One button controls the fan speed and the power to the purifier, so it’s easy enough for anyone to use. No matter how long you run the Koios Desktop Air Purifier, you can count on it to keep your electricity bill low. As a bonus, it has a built-in LED nightlight to help you relax or fall asleep.


Small and Energy Efficient

This air purifier only stands 7.5 inches tall and has a diameter of 6.9 inches; therefore, it fits nicely on your desk, nightstand or kitchen counter without taking up valuable space. Since it weighs a featherlight 2.1 pounds, moving it to a new location requires no effort.

It even has a blue LED ring that acts as a soothing nightlight. You don’t have to worry about it consuming a lot of electricity; the purifier only needs 8 watts to operate and 0.5 watts when it’s on standby.

Three-Layer Filter

As air flows into the bottom outlet that circles around the purifier, the outer layer of the filter blocks pollen, dust mites and other large particles. Then, 99.97 percent of the 0.3-plus micron particles are captured by the HEPA filter in the middle. These particles include airborne contaminants like bacteria, mold and pet dander.

Finally, the inner activated carbon layer eliminates odors caused by cooking, cigarette smoke and pets. After the now-clean air passes through all three layers, it’s released via the outlet at the top of the purifier.

Easy to Operate

With just one button to control the entire air purifier, operating it is uncomplicated. Simply press the button to turn the purifier on and off as well as change between the two fan speeds. On its highest speed, the fan blows air at a rate of 16 cubic feet per minute, and it does it almost silently too. Even the necessary biannual filter change is simple and quick. To replace the filter, flip the purifier over and turn the knob counterclockwise to remove the cover. After inserting the new filter, replace the cover and turn the knob clockwise to secure.
