It features with 3 modes (Normal/Nature/Sleep) and 3 wind speeds (Low/Medium/High) to offer a wide range of use for any activity. It can absorb the surrounding hot air and cool it down quickly, creating a comfortable space environment for you.
- ❄️【Internal Turbo Technology】 The internal turbo design of this windowless room air conditioner can guide the air flow more effectively, generate stronger wind power, and the noise is relatively small. It can balance the temperature and promote air circulation, which is something that ordinary fans cannot do.
- ❄️【120° Oscillation】 The inner blades are designed with auto-swings horizontally by 120° to cool down the area evenly. Moreover, vertical airflow can be adjusted to 20° through its manual shutters for maximum cooling, ensures air is evenly distributed throughout the area, providing a comfortable breeze. It efficiently produces 25.6ft/s of strong airflow, and cools spaces of up to 300 sq.ft within minutes.

- ❄️【Cool Function】When you use the “Cool” function, please add water and ice packs to the water tank, and this cooling fan will blow cooler wind. This swamp cooler includes 4 upgraded ice bags.

## Customer Reviews

### ⭐ Not worth purchasing
*by D***I on August 26, 2025*

This AC did nothing more than act as a fan. The filter on the back that was supposed to be wet by the ice cold water always turned bone-dry, even after manually soaking it. We ending up returning it.

### ⭐⭐ Glorified fan, absolutely useless “cooling” ability.
*by M***5 on July 16, 2025*

2 stars only because I feel bad giving it a 1 star. This is a FAN. This does not blow cold or even cooled air whatsoever. The idea is a tube pulls ice water from a tank and empties it above a filter. The filter is supposed to get drenched in cold water, so when the air is pulled from the back of the unit, it passes through the cold soaked filter and then blows chilled air into the room. It does not do this with any level of efficacy at all. The water tube sucks water out of the tank as such a slow pace that it barely drips the water into the filter, so the air passing through isn’t cooled at all. This is a glorified fan with an absolutely useless water tank at the bottom. Save your water, save your ice, save your time, save your money, and don’t even consider buying this product. I’ll be returning it tomorrow after using it for barely half a day.

### ⭐ Not that effective
*by C***  on October 3, 2024*

Remote that comes with the unit is cheap and never worked, I even changed the battery. Water container on the unit has a hose attached so you can't remove the container to empty the water, you have to carry the entire unit to somewhere that you can tip it over so that the water pours out. Whatever the temperature of the water that is in the container is how cool the air that blows out will be. It comes with 4 freezer packs that you place in the water container in order for it to blow out cool air. Using only two freezer packs hardly cooled off the small office room it was placed in. Maybe using chilled water with the 4 freezer packs would make it more effective? I returned them since it's way to much hassle to use in an office environment.
