Okaysou Air Purifier Review
My cat has picked up a nasty habit that I am desperately striving to change. Almost every evening, she returns to the house with a mouse clenched between her jaws. Velvet then drops the panicky rodent onto the floor and chases it around. I suppose this has something to do with instinct, but, to me, it comes across as mean and pitiless.
Yesterday I noticed a particularly nasty odor emitting from my office. Suspecting one of my cat’s mortally wounded victims had hidden and later expired in the room, I spent an hour emptying cabinets and pulling them away from the wall. I was correct, but it wasn’t a mouse. She’d brought a full-grown rat into my house!
After cleaning up the mess, I turned on the window fan, set my Levoit air purifier to its maximum speed, and closed off the room. It didn’t work. The next morning my office smelled just as bad.
By lucky coincidence, my new Okaysou air purifier arrived that very day. The AirMax8L is a huge, multi-filtered unit intended to clean the air of very large rooms. I placed the air purifier into the tiny office and turned it to its maximum speed. Five hours later, the room smelled fresh and clean.
While not the type of situation an air purifier is typically expected to cope with, this little success puts me in a positive frame of mind as I write this review.
The Okaysou AirMax8L Air Purifier weighs in at about 10 pounds. It is 19.4 inches high, 12.9 inches wide, and 7 inches deep.
The main body is composed of white plastic, although, to provide contrast, the air purifier’s upper surface is colored black.
A sizable fan situated inside the air purifier draws air through two multi-filters. The clean air is then driven upward and out.
Various controls, accessible at the top of the unit, allow changes to fan speed and permit the operator to adjust how long the air purifier will remain on. There is also a child lock and a sleep mode button.

Five-Step Filtration System
This air purifier is fitted with two filtration units. The outer unit incorporates a Pre-filter and a HEPA filter, which removes most airborne particles. Also included is an Antimicrobial filter designed to ensure bacteria do not grow inside the air purifier and to eliminate some viruses, bacteria, and germs.
The inner filtration unit includes an activated carbon filter, which extracts unpleasant odors, smoke, and formaldehyde. A Cold Catalyst filter intended to remove VOCs, ammonia, and hydrogen is also integrated into this unit.
These filtration units, which are priced at about 20 dollars each, should be replaced every six to eight months.
The AirMax8L has a CADR (clean air delivery rate) of 210 square meters per hour. This figure denotes the amount of air that is cleaned of particles, sized 0.3 microns or larger, within one hour.
This air purifier can recirculate the air of a 500 square feet room within 20 minutes. In a 320 square foot room, the air is exchanged five times every hour.
My Levoit air purifier is useful, but because of its compact size, the device’s fan must rotate very quickly. When the air purifier is running at its highest setting, the noise produced by its quickly rotating fan becomes quite annoying.
The Okaysou AirMax8L is equipped with a 14.17 x 9.52-inch intake, two massive filter units, and a large 45 vane turbine. This device can move the same amount of air at significantly lower fan speeds than its smaller competitors.
The air intake is located at the rear of the unit in order to help minimize noise levels. To ensure proper circulation, Okaysou recommends that a clearance of 18 inches be maintained between the air purifier and a wall.
Noise levels range from a whisper-quiet 28db in sleep mode to about 60db at the maximum of this air purifier’s three speeds.
If properly maintained, this air purifier will last for many years. The two replaceable filter units are rated for six to eight months.
The AirMax8L is guaranteed for five years, which, while unusual, does make sense. Owners are likely to continue purchasing filters rather than replacing their air purifiers as long as the device is protected by a warranty.
This device is well-designed and equipped with a far more advanced filtering system than you would normally expect to find in this price range. If you are looking for an air purifier capable of handling medium to large-sized rooms, the Okaysou AirMax8L is strongly recommended.
