Silver Onyx Desk Air Purifier Review

The SilverSilver Onyx 5in1 Onyx desk HEPA filter has some impressive air cleaning technology packed into it, including extras you don’t often see at this size.

Within its compact tower design this model utilizes 5 different stages of air purification:

  1. An H13 medical-grade True HEPA filter. H13 HEPA is superior to H11 filters used in the majority of competitors.
  2. A mesh prefilter to trap hairs, lint and pet dander. This can be vacuumed occasionally to increase the HEPA filter’s efficiency.
  3. An activated charcoal filter to neutralize bad smells and odors. Activated charcoal also combats harmful VOCs and can remove indoor ozone.
  4. An optional ‘Vita-Ion’ air ionizer, generating 3 million ions per second. Negative ions combat tiring positive ion pollution in office environments.
  5. An optional UV-C light with antibacterial photocatalyst layer to kill viruses and bacteria. Office cubicles are often full of airborne pathogens so this is a useful feature to have.

The Silver Onyx air cleaner comes in 3 stylish black, silver and white designs and is 10.5 x 16.5 inches and weighs 5.3 pounds.

The touch control panel on top has extra features, usually only seen in larger and more expensive models including:

  • 5 fan speeds in manual mode. Set it on high to clear smoke, when pets are around or on heavy pollen days.
  • An auto mode that adjusts to the level of indoor air pollution and displays different colors, blue for good down to red for poor, on the air quality indicator.
  • A PM 2.5 air quality indicator so you can tell how the Silver Onyx is working to purify the air in your workspace.
  • An auto timer you can set from 30 minutes to a full 24 hours.
  • Optional ionizer and UV-C/photocatalyst buttons. Both of these functions can be switched on or off.
  • Sleep mode, where lights turn off and the fan runs at the lowest speed. Silver Onyx says their tabletop model is whisper quiet in sleep mode at just 25 dB.
