Our Review Of The Okaysou AirMic4s Air Purifier:

I found that the Okaysou H13 air purifier was extremely easy to unpack and get started. It as intuitive operation controls and can be set up within minutes. One point to note, be sure to unscrew the base and remove the plastic wrapping around the filter canister prior to operating the air filter.

Air Filter:

Okaysou AirMic4s HEPA Filter
The air filter uses a three-stage purification system. Stage one consists of a washable and detachable prefilter. This is good for capturing large particles such as dust, pet for, hair, fibers, etc.

Stage two contains the home medical grade H13 true HEPA filter. This HEPA filter removes up to 99.97% of airborne particles 0.3 µm in diameter. It can remove small particles such as smoke, small dust particles, mold spores, viruses, bacteria, and allergens.

The third stage consists of a high-efficiency active carbon filter. This is perfect for absorbing stubborn and un-wanted odors and fumes. This can also filter compounds like Formaldehyde, ammonia, hydrogen sulfide, benzene, and volatile organic compounds (VOCs).

The manufacturer recommends replacing the filter every 6 to 8 months. However, they do know that you might need to replace your filter sooner depending on the frequency of use.

In the instruction manual, they note that you might need to replace your filter if you notice the following:

  • Increased noise when the air filter is on
  • Decreased airflow
