10 Best Portable Air Coolers in 2026

The heat hits, and the first thing you notice is the absence of a breeze. A desk fan just pushes warm air around. A window AC requires installation, landlord permission, and a summer of cranky electricity bills. That is the gap a portable air cooler fills. These evaporative coolers pull in hot air, pass it over a wet pad or through a mist, and send out air that feels noticeably cooler and more humid. They work best in dry climates or arid rooms, and they use a fraction of the power of a compressor-based unit. But the category ranges from palm-sized desk toys to rolling floor towers with seven-gallon tanks. Picking the wrong one means getting a trickle of lukewarm air when you wanted a room-wide chill.

We sorted through the ten most popular portable air coolers on Amazon, evaluating them for how much real cooling they deliver, how often you have to refill, how loud they get, and whether they actually cover the space they claim to. The result is a set of picks that spans personal desktop coolers, mid-room towers, and heavy-duty swamp coolers for garages or large bedrooms. Here is the short version.

TL;DR: The LIFECREEK Portable Air Cooler with its 3.2-gallon tank and six ice packs is the one most people should buy for a medium-sized room. The CrmyPeg 7.5-Gallon Swamp Cooler is the answer for large spaces and all-day operation. The FODFINU 3.5-Gallon Cooler is the quietest option for bedrooms. The Arctic Air Pure Chill 2.0 is the best personal desktop unit. And the ChillWell 2.0 is the most portable battery-powered pick for camping or travel.

How We Picked

• Tank capacity and real-world run time. A cooler that runs dry after two hours is an annoyance. We prioritized units that can go a full workday or a full night without a refill. Larger tanks (3+ gallons) matter for whole-room use; smaller tanks (under 1 liter) are acceptable for personal desktop cooling if the unit is easy to refill.
• Cooling method and effectiveness. Some coolers rely only on a fan blowing over a wet pad. Others add ice packs or dual ultrasonic atomizers that create a fine mist. We looked for the approach that delivers a noticeable temperature drop rather than just a humid breeze.
• Noise level. Evaporative coolers can be surprisingly loud because of water sloshing and pump motors. We favored units that stay under 45 dB or offer a dedicated sleep mode. A quiet unit makes the difference between a cool night and a sleepless one.
• Portability and footprint. A cooler that sits on a desk must be compact and light. A floor unit needs casters or at least a handle. We considered how easy it is to move the cooler from the bedroom to the living room or pack it for a trip.
• Build quality and features. Plastic that feels hollow, a pump that rattles, or a flimsy remote are red flags. We looked for solid construction, intuitive controls (touch panel, remote, timer), and features that actually get used: oscillation, adjustable mist levels, and water-level visibility.

1. LIFECREEK Portable Air Cooler: Best Overall

Pros

• Huge 3.2-gallon tank lasts through a full workday or night without refilling.
• Comes with six reusable ice packs that slot into the tank for an extra chill.
• Rolling casters and a top-fill design make setup and moving genuinely easy.
• Four modes including a dedicated cooling mode; remote control works from across the room.

Cons

• At 10.4 pounds it is not something you want to carry up and down stairs regularly.
• The plastic housing feels a bit thin around the water-level window.
• Sleep mode could be quieter; the pump is audible in a silent room.

Best for: Anyone with a medium-sized bedroom or home office who wants set-it-and-forget-it cooling without a window unit.

The LIFECREEK hits the sweet spot between tank capacity and practicality. With a 3.2-gallon reservoir, you can fill it in the morning and not think about it until bedtime. The top-fill opening is wide enough to pour from a pitcher without spilling, and there is a clear water-level window on the side so you can see at a glance how much is left. The six included ice packs are not an afterthought. They are sized to fit the tank easily, and when you freeze them overnight and drop them in, the outgoing air is genuinely cooler than what most desk fans produce. The unit oscillates, though the range is modest, and the remote gives you full control from across the room. The casters are a real plus. Most coolers at this size expect you to lift them; this one rolls. The three speeds are enough, and the four modes (Normal, Natural, Sleep, Cooling) give you room to adjust. The cooling mode runs the pump continuously for maximum evaporation, which is exactly what you want on a scorching day. The sleep mode cuts fan speed but keeps the pump running intermittently. It is not whisper-quiet, but it is quieter than most window ACs. The biggest compromise is the build. The plastic casing has a hollow feel, and the water-level window sits in a cutout that looks like it could crack if the unit takes a hard knock. But for the money, you get more cooling substance than any desktop evaporative cooler can deliver.

2. CrmyPeg 4-in-1 Swamp Cooler: Best for Large Spaces

Pros

• Massive 7.5-gallon tank can run for up to 30 hours on low, making it a true all-day cooler.
• Four included ice packs plus a three-sided ice curtain that filters dust and pet hair.
• 120-degree oscillation covers a wide area; claims up to 300 square feet.
• Swivel casters and a bottom drain port simplify cleaning and moving.

Cons

• Very tall (31.6 inches) and heavy; not something you tuck under a desk.
• The ice curtain adds cooling but also increases noise from the pump pushing water.
• No sleep mode: the lowest fan setting is still fairly audible in a quiet bedroom.

Best for: Large living rooms, open-plan apartments, garages, or workshops where you need sustained cooling for hours without refills.

The CrmyPeg is the heavy lifter of this roundup. If you have a space bigger than a standard bedroom, or if you just do not want to babysit a water tank, this is the one. The 7.5-gallon reservoir is enormous. On the lowest fan setting, the company says you can get 30 hours before needing a refill. Even on high, it will outlast any other unit in this list by a wide margin. The three-sided ice curtain is an interesting design: it serves as a pre-filter that traps dust and pet hair, and it cools the water before it hits the evaporative pad. In practice, that means the air feels fresher and slightly cooler from the start. The four ice packs add another layer of chill. The oscillation sweeps 120 degrees, which actually moves air across a room rather than just in one spot. The build is solid. The unit sits on four swivel casters and rolls smoothly over hardwood and tile. The bottom drain port makes emptying the tank for cleaning far less messy than tipping the whole thing over. The downsides are size and noise. This is a floor-standing appliance that is over two and a half feet tall. It dominates a corner. The fan and pump are not subtle; on the highest setting, you will hear it across the room. There is no dedicated sleep mode, so if you are sensitive to noise, this is not a bedroom pick. But for a living room or garage, it is the most effective portable cooler here.

3. FODFINU Swamp Cooler: Quietest for Bedrooms

Pros

• Claims a noise level of 45 dB, which is quieter than a typical conversation and barely noticeable in a bedroom.
• 3.5-gallon tank delivers up to 12 hours of cooling per fill, covering a full night's sleep.
• Four fan speeds plus a dedicated sleep mode that drops the fan to its lowest, quietest setting.
• Includes four ice packs and supports aromatherapy (just add a few drops to the water).

Cons

• The hand pump must be manually placed into the water tank after filling, which is an odd extra step.
• The oscillation range is wide but the vertical adjustment is manual and limited.
• The remote feels cheap and has a short range compared to others.

Best for: Light sleepers who need cool air and quiet operation in the bedroom.

The FODFINU tries to solve the two biggest problems with evaporative coolers: noise and refilling. On the noise front, it mostly succeeds. At 45 dB, the fan and pump are quiet enough that you can fall asleep with it running. The sleep mode drops the fan to the lowest speed, and the pump cycles on and off so the hum does not become a drone. The 3.5-gallon tank is generous for a unit this size. Twelve hours of run time means you can fill it before bed and not think about it until the next evening. The four ice packs fit into a compartment at the back, and they make a real difference in the first few hours. The cooling pad is washable, which is nice for maintenance. The unit has casters, but they are small and plastic, so it rolls better on hard floors than carpet. The oddest thing about the FODFINU is the hand pump. The instructions tell you to remove the pump from the unit body and place it into the water tank. It is a small hassle that is easy to forget, and if you do, the unit runs as a fan only. The remote is basic and only works reliably within about ten feet. Still, for a bedroom, the trade-off is worth it. The quiet operation is real, and the cool air it produces is enough to take the edge off a warm night without waking you up.

4. Zenolix 4-in-1 Tower Fan Cooler: Best Tower Design

Pros

• Tall, slim tower design fits into corners and spaces where a boxy cooler would look out of place.
• 1200 ml water tank with a fine mist spray that adds noticeable humidity and cooling.
• 120-degree oscillation and four fan speeds provide good room coverage for a desktop unit.
• Remote control and a 12-hour timer make it easy to set and forget.

Cons

• The tank is small relative to the cooler size, lasting only a few hours on high mist.
• The plastic feels lightweight, and the base is not very stable if bumped.
• The mist can leave a fine layer of moisture on nearby surfaces if the unit is too close.

Best for: Someone who wants a cooling tower that blends into a home office or living room and prefers remote convenience.

The Zenolix stands out visually. It is a tall, white tower that looks more like a modern fan than a plastic box of water. That design matters if the cooler is going to sit in a visible spot. The oscillation is genuinely wide, and the four fan speeds range from a gentle whisper to a strong breeze. The fine mist spray is the key feature here. It creates a literal cloud of cool air that feels good on the skin, especially in dry climates. The 1200 ml tank is refilled from the top, and a 12-hour timer means you can set it to run all day and turn off automatically. The remote works well from across the room. The downsides are the tank capacity and the build. The 1200 ml tank is small for the size of the unit. On the highest mist setting, you will need to refill every two to three hours. There is a water-level indicator, but it is not backlit, so it is hard to read in low light. The tower wobbles a bit if you push it, and the plastic base feels like it could snap if you are not careful moving it. But as a desk or floor tower that actually looks good, the Zenolix fills a niche that most boxy evaporative coolers ignore.

5. Arctic Air Pure Chill 2.0: Best Personal Desktop Cooler

Pros

• Small footprint (roughly the size of a tissue box) fits on any desk without taking over.
• Hydro-Chill Technology uses a wet cartridge to cool and humidify air effectively for one person.
• Four fan speeds and a built-in LED nightlight with seven color options.
• Runs for up to 10 hours on a full tank, depending on settings.

Cons

• Only cools personal space, not a room. The airflow is narrow and directional.
• The water tank is not large; on high mist you will refill more often than 10 hours.
• The fan is quiet but not silent; the pump adds a faint whirring sound.

Best for: Office workers, students, or anyone who needs a personal cooling zone at their desk without disturbing coworkers.

Check current price on Amazon →

The Arctic Air Pure Chill 2.0 is the most popular personal evaporative cooler on Amazon for a reason. It is simple. You fill the top tank with water, plug it into a USB or wall outlet, and choose your fan speed. The Hydro-Chill cartridge absorbs water and the fan pulls air through it, dropping the temperature by a few degrees. It is not going to cool a room, but sitting two feet away on a desk, it makes a real difference. The four fan speeds let you dial in exactly how much breeze you want. The LED nightlight cycles through seven colors, which is more of a mood feature than a practical one, but it is nice to have. The run time is decent. On the lowest fan setting with no mist, you can get close to 10 hours. On high mist, expect more like four to five hours. The tank is not removable, so you pour water into the top. It is easy enough, but you cannot take it to a sink. The build is solid for the size, though the plastic feels a bit light. The biggest limitation is the narrow airflow. The Pure Chill 2.0 is designed for one person. If you need to cool a room, keep scrolling. But as a personal desk cooler, it is well executed and dependable.

6. Arctic Air Ice Jet X3: Best Travel Cooler

Pros

• Extremely compact and lightweight (1.43 pounds), easy to toss into a bag.
• USB-C powered, so you can run it from a laptop, power bank, or car adapter.
• Dual mist modes (high and low) plus three fan speeds for fine control.
• Double-walled insulated reservoir keeps water cooler longer.

Cons

• Small water capacity; on high mist you get maybe two hours before refilling.
• The adjustable head moves up and down but does not swivel side to side.
• The fan is quiet at low speed but gets noticeably loud on high.

Best for: Travelers, campers, or anyone who wants a portable cooling option that runs off USB-C.

Check current price on Amazon →

The Arctic Air Ice Jet X3 shrinks the evaporative cooler concept down to something that can sit on a nightstand or fit in a cooler bag. It is powered by USB-C, which is a big deal for portability. You can plug it into a power bank and take it to a campsite, a tailgate, or a desk where wall outlets are scarce. The insulated reservoir is a smart touch. It keeps the water cold longer, which means the mist stays cooler for the first hour or so. The dual mist modes let you choose between a gentle moisture and a heavier spray. The three fan speeds are enough. The design is rounded and compact, with a head that tilts up or down. It feels solid for its weight. The drawbacks are capacity and coverage. The tank is small, so on the highest mist setting you will need to refill often. The airflow is directed and does not oscillate, so it only cools the spot you aim it at. The fan is quiet on low but not silent. For a travel unit, though, these are acceptable trade-offs. The Ice Jet X3 is not a room cooler. It is a personal zone cooler that goes where you go.

7. Anyrap 16" Standing Fan Cooler: Fast Mist Cooler

Pros

• 16-inch tower design with a tall air column that covers more of your body than a desktop box.
• Dual ultrasonic atomizers claim to drop temperature from 86°F to 68°F in three seconds.
• 120-degree oscillation with five modes and four speeds for flexibility.
• 650 ml top-fill tank with a water-deficiency auto shutoff.

Cons

• The “3-second cooling” claim is highly dependent on ambient humidity; in humid rooms the effect is minimal.
• The 650 ml tank is small for a standing cooler; expect refills every two to three hours.
• Touch controls are not backlit, making them hard to see in the dark.

Best for: Someone who wants a tall, oscillating fan that also delivers a fine mist for instant skin cooling.

Check current price on Amazon →

The Anyrap looks like a regular standing fan at first glance. But the base houses a 650 ml water tank and two ultrasonic atomizers that shoot a cold mist into the airflow. The result is a breeze that feels noticeably cooler than a standard fan. The tall column means the air hits you from head to toe, unlike a desk cooler that only chills your torso. The 120-degree oscillation spreads that cool air across a wide arc. The five modes include a natural wind pattern and a sleep mode. The four fan speeds give you control over intensity. The machine is lightweight at 3.2 pounds, so moving it around the house is easy. The 3-second cooling marketing is hyperbolic. What it means is that the mist starts instantly, and your skin feels cooler almost right away. But in a humid environment, evaporative cooling loses effectiveness. The tank is small for a standing cooler. Refilling from the top is simple, but you will do it often if you run the mist on high. The touch controls are unlit, which is annoying in a dark room. The build is mostly plastic, and the base feels a bit light, but it has not tipped over during normal use. This is a good choice for people who want a tall fan with a cooling boost, not a standalone air conditioner replacement.

8. MLLFW 4-in-1 Personal Cooler: Best for RGB and Remote

Pros

• Seven RGB light modes create a mood lighting effect that cycles or stays on one color.
• 40 oz (1200 ml) water tank claims up to 10 hours of continuous cooling on low.
• 3-second rapid cooling with dual atomizers and triple refrigeration tech.
• Remote control works from 16 feet, and the unit weighs only 3 pounds for easy portability.

Cons

• The RGB lights are bright and cannot be dimmed, which may be too much for a bedroom.
• The cooling effect is real but heavily dependent on adding ice for a noticeable drop.
• The plastic handle feels flimsy and the build quality is average.

Best for: Gamers, dorm residents, or anyone who wants a cool-colored light show with their personal air cooler.

Check current price on Amazon →

The MLLFW is aimed at a younger, more style-conscious user. The seven RGB light modes are the headline: you can set it to a single color or let it cycle through a rainbow. The lights are on the front and they are bright, so this cooler doubles as ambient room lighting. The cooling side is legit. The dual atomizers and a high-speed motor push out a fine mist that feels cold when it hits your skin. The 40 oz tank is larger than most personal coolers, and the company claims up to 10 hours of run time. In practice, on the highest mist setting, you will get more like four to five hours before a refill. The remote works well from across a dorm room. The unit is small and light enough to move from desk to nightstand. The downsides are the build and the lights. The plastic body has a cheap, hollow feel. The handle on top is thin and flexes when you carry it. The RGB lights cannot be adjusted in brightness, so in a dark room they are distracting. The “3-second cooling” claim is again dependent on cold water and ice. Without ice, the cooling is more like a humid fan. But if you want a colorful desk companion that also provides a cooling mist, the MLLFW fits the bill.

9. ChillWell 2.0 Evaporative Cooler: Best Battery-Powered Portable

Pros

• Built-in rechargeable battery provides up to 4 hours of cordless cooling, great for camping or power outages.
• Compact square design (roughly 6 inches), easy to pack in a duffel bag.
• Four fan speeds including a “Super Chill Turbo Mode” for maximum cooling.
• Insta-Frost Technology uses a cooling cartridge that absorbs water and delivers chilled air quickly.

Cons

• Small 550 ml water tank means frequent refills, especially in Turbo Mode.
• Battery life is only 4 hours, and recharging takes a while via USB.
• The cooling cartridge needs to be soaked before first use, which is an extra step.

Best for: Campers, van-lifers, or anyone who needs a cooler that runs off battery without a wall plug.

Check current price on Amazon →

The ChillWell 2.0 is the only unit in this roundup with a built-in rechargeable battery. That changes what it can do. You can take it to a campsite, use it in a tent, charge it in the car, and set it on a picnic table. When plugged in, it runs up to 8 hours on low. On battery, you get about 4 hours, which is enough for a night in a tent or a long afternoon at a park. The Insta-Frost cartridge is a key part of the design. You soak it in water, and the fan pulls air through it. The cartridge stays cool for a while, but it does not hold as much moisture as a traditional pad. The four fan speeds are good, and the Turbo Mode is noticeably stronger. The 550 ml tank is small. Expect to refill it every two to three hours on high. The unit is light and square, fitting easily into a backpack side pocket. The build is mostly plastic, but it feels sturdy enough for travel. The nightlight with seven colors is a nice touch for camping. The biggest trade-off is coverage. The ChillWell 2.0 is strictly a personal cooler. The airflow is narrow and does not oscillate. But for portable, battery-powered cooling, it is the most functional option.

10. Cokque Mini Personal Cooler: Most Compact USB-C Option

Pros

• Ultra-compact at 9.7 x 7.2 x 4.9 inches and only 1.98 pounds, the smallest cooler in this roundup.
• USB-C powered, so it works with laptops, power banks, and car chargers.
• 1100 ml water tank is surprisingly large for such a small unit, claiming 10 to 15 hours of humidification.
• Comes with a remote control, a rare feature in sub-2-pound coolers.

Cons

• The fan is not very powerful; it moves a gentle breeze that is noticeable only within arm's reach.
• The mist output is modest; do not expect a strong cooling effect without ice.
• The remote is tiny and easy to lose.

Best for: People who want an almost weightless cooler for a small desk, car, or nightstand with the convenience of USB-C power.

Check current price on Amazon →

The Cokque prioritizes being small and light. At under two pounds, it is the lightest cooler here. The USB-C power means you can run it from a laptop USB port or a phone charger. The 1100 ml tank is generous for a device this size. The company claims 10 to 15 hours of humidification, which is plausible on the lowest mist setting. The remote control is a surprising inclusion at this size. It lets you adjust fan speed, mist mode, and the timer (2, 4, or 6 hours) without getting up. The water level is visible through a clear panel. The no-water protection automatically stops the spray when the tank is low, which protects the pump. The downsides are power and mist intensity. The fan moves a gentle breeze, not a strong one. On the highest setting, you feel it from two feet away, but not across a desk. The mist output is fine for a small personal space, but it does not produce a visible cloud like some larger units. The build is all plastic, and the remote is easy to misplace. For someone who needs a barely-there cooler that runs off USB and looks unobtrusive, the Cokque does the job without taking up space.

Buyer's Guide: How to Choose a Portable Air Cooler

The portable air cooler market is full of optimistic claims about square footage and temperature drops. To cut through the noise, focus on a few concrete specs and real-world behaviors.

Tank Size and Run Time

The water tank determines how long the cooler can run before you have to get up and refill it. For a desk cooler, a tank under 1 liter (about 34 oz) means refills every two to four hours. That is fine if you are sitting right there. For a bedroom cooler, look for at least 3 gallons if you want to make it through a full night without interruption. A larger tank also means you can add more ice, which extends the cooling effect. But bigger tanks mean bigger, heavier units. The trade-off is between convenience and portability.

Cooling Method: Pad vs. Mist vs. Atomizer

All evaporative coolers work by passing air over water, but the mechanism matters. Pad-based coolers (like the Arctic Air Pure Chill) use a sponge or cellulose pad that wicks water and the fan blows through it. They are quiet and simple, but the cooling is modest. Mist-based coolers spray water into the airflow using a nozzle. They provide a more noticeable cool blast, but they can dampen nearby surfaces. Ultrasonic atomizers (like in the Anyrap and MLLFW) vibrate water into a fine fog. They produce the most dramatic temperature drop on the skin, but they also consume water fastest. For dry climates, atomizers are a clear win. In humid conditions, all evaporative cooling loses effectiveness, but pad coolers fare slightly better because they do not add as much moisture.

Fan Speed and Noise

A cooler that sounds like a blender defeats the purpose. Check the decibel rating. Under 40 dB is whisper-quiet; 40 to 50 dB is acceptable for a bedroom if you are not a light sleeper. Above 50 dB, expect a constant hum that might bother you during work or sleep. Also look for a sleep mode that drops the fan to the lowest speed and cycles the pump on and off to reduce noise. Some units have quieter pumps than others, and that is hard to know without hearing them. As a rule, larger tanks and more powerful fans produce more noise.

Oscillation and Coverage

A cooler that only blows air in one direction is okay for personal use, but for any shared or larger space, oscillation is essential. Most coolers in this price range offer 60 to 120 degrees of horizontal oscillation. The wider the arc, the more even the cooling across the room. Vertical oscillation is rare in this category. Some coolers let you manually tilt the head, but that is not the same as automatic vertical sweep. If you need to cool a room, prioritize a unit with 120-degree horizontal oscillation and a tall fan column (at least 12 inches) to distribute air at different heights.

Controls and Convenience Features

Touch controls on the unit are standard, but a remote control makes a big difference when the cooler is across the room. A timer (2 to 12 hours) is useful for sleep or workday scheduling. A visible water level window or top indicator prevents running the pump dry. Some coolers have auto shutoff when the water runs out, which protects the pump. USB power is a plus for desktop use or travel. Battery power (like in the ChillWell 2.0) is rare but transformative for camping or areas without convenient outlets.

Frequently Asked Questions

Do portable air coolers actually work?

Yes, but within limits. They lower the temperature of the air through evaporation, which works best in dry climates. In humid weather, the effect is reduced. They are not a replacement for an air conditioner in hot, humid conditions. But in dry heat or a moderately warm room, they can make the air feel several degrees cooler while using a fraction of the electricity.

How much water does a portable air cooler use?

It depends on the unit and the setting. A personal desk cooler with a 500 ml tank might need refilling every two to four hours. A large floor cooler with a 3-gallon tank can run for 10 to 12 hours. The higher the fan speed and the more mist you use, the faster the water evaporates.

Can I use a portable air cooler in a closed room?

Yes, but you need some airflow. Evaporative coolers increase humidity, and in a sealed room, the air can become uncomfortably damp. Crack a window or leave a door open to allow some air exchange. That helps the cooler work more effectively because it can pull in drier air.

Are portable air coolers safe for pets?

Generally yes. The mist is just water, and the units do not get hot or use refrigerants. However, keep the water tank clean to prevent mold or bacteria growth, which can be harmful if inhaled. Clean the unit and change the water regularly.

How do I clean a portable air cooler?

Empty the water tank, disassemble any removable pads or filters, and wash them with mild soap and water. Wipe down the interior of the tank with a vinegar solution to prevent scale and algae. Most coolers recommend cleaning every one to two weeks during regular use.

What is the difference between a swamp cooler and a portable air conditioner?

A swamp cooler (or evaporative cooler) uses evaporation, adding moisture to the air. A portable air conditioner uses a compressor and refrigerant, removing heat and often dehumidifying. Swamp coolers cost less to run but only work well in dry climates. Portable ACs work in any climate but are more expensive and require a vent hose to a window.

Can I put ice in the water tank?

Yes, and it helps. Adding ice to the tank or using included ice packs lowers the water temperature, which means the air coming out is cooler. However, the effect is temporary. Once the ice melts, the cooler returns to its baseline evaporation temperature.

---

Final Verdict

The LIFECREEK Portable Air Cooler is the top pick for most people because it balances a large tank, effective cooling with ice packs, and features like casters and a remote that make it easy to use in a bedroom or office. If you need to cool a large area or want to go a full day without a refill, the CrmyPeg 7.5-Gallon Swamp Cooler is the workhorse you want. For a quiet bedroom solution, the FODFINU delivers the lowest noise level in a mid-size package. And for personal desk cooling or travel, the Arctic Air Pure Chill 2.0 and ChillWell 2.0 cover those niches well.

If you are still undecided, think about where you need the cool air most. A desk user should get a personal cooler like the Pure Chill 2.0 or the MLLFW if they want RGB lights. A bedroom or home office user should step up to a floor unit with a 3-gallon tank. And anyone who needs to beat the heat in a garage, workshop, or large living room should go straight to the CrmyPeg. That unit will not run out of water, and it will not run out of breeze.
