Costway's evaporative air conditioners are cheaper than compressor air conditioners and require less maintenance.

Summer is coming soon. In some places in the United States, such as Los Angeles where I am, it is already here. The only way to survive these 80-degree days is to use air conditioners, and portable air conditioners with wheels are a convenient and versatile way to cool your room without spending a lot of money on air conditioners. Costway has an affordable portable air conditioner with a remote control, which usually sells for about $136 on Amazon and Costway's own website. But now, when you apply the promotional code CNETPAC at checkout, as long as the supply continues, you can get the Costway 215 CFM air conditioner cooler and remote control for $125. 

This is an evaporative cooler, sometimes called a swamp cooler. This kind of air-conditioning device does not use a compressor to cool the air, but sucks in the air through a fan, and then passes through a reservoir to keep a certain medium moist. The moisture in the material evaporates and cools the air. Therefore, although there is no waste water tank that needs to be emptied every few hours, you do need to fill up the 8 liter water tank to start the process. Costway also includes an ice box-in addition to water, you can also enhance the cooling effect by adding ice cubes to the system. 

The air conditioner should run most of the day at the three fan speeds you choose, and have a 7.5 hour timer to automatically shut down the system. It can be used as a cooler, humidifier, fan or even air purifier, and is equipped with a removable and washable filter to prevent the spread of bacteria, dust and other airborne particles.
