Three in One Filtration System

Many air purifiers use three levels of filtration, and that technology is proven to work best. Koios also has this system. The first filter is used to grab all the big particles, while the True HEPA system is used to eliminate all the small particles.

The True HEPA filter in Koios air purifier is powerful to grab 99.97% of airborne particles. Pollen, dust,  smoke, mold spores, and pet dander can easily be removed with this air filtration system.

The Carbon Layer on the filter is included to remove bad smells and unpleasant odors.

How it Works:

The air gets sucked from the bottom of the air purifier and goes through the three-stage filtration system. All the pollutants are removed in the process, and then on the top, the fresh, clean air gets ejected. You can put your face on the top of the air purifier to feel the fresh air.

Filters need to be replaced every six months for best performance and to keep high-quality air in the room. There is no filter replacement warning, so you need to monitor the quality of the filters by yourself.

Easy to Understand and Portable

There is not much to do with this simple device. You just need to push a button, and the air purifier will do its work. The Koios Desktop air purifier has two speeds and depending on the pollution in the air you should choose a higher or lower speed.

Being a portable air purifier means that you can without a problem use this air purifier in different rooms. You can transfer it from place to place and keep it close to you at all times. It is like bringing fresh air with you.

Extremely Low Power Consumption

Being small and portable and having only two speeds saves energy. The Koios air purifier will use as little as 8 watts at maximum speed. While being on standby, it will use less than 0.5 watts.

For an air purifier that is capable of removing 99.97% of airborne particles, this is extremely low energy consumption.


The design of this air purifier follows the trend. It is a modern cylindrical design that will fit any room. Maybe folks that visit your home will ask about the device because it looks like it is some futuristic device.


If you decide to buy this device, you will get a 3-year warranty, and the customer service of Koios is at your disposal for 24 hours a day. Just contact them if you have any troubles with this product.
