The 40851-NQPC replacement carbon ring combines activated carbon and potassium permanganate to effectively adsorb chemicals, VOC's, and odors from the air.

Almost all odors are connected with gases, and even HEPA filters have almost no ability to remove them from the air you breathe. Therefore, the best solution to odor control uses a combination of adsorption and oxidation.

The 40851-NQPC replacement carbon ring is compatible with the NQ Clarifier Standard, NQ Clarifier Medical, and NQ Clarifier Medical Plus air purifiers, has the ability to trap impurities such as VOC's, chemicals, and odors, and lasts up to 24 months with normal use. As well, for those tough-to-remove odor causing particles such as tobacco smoke, the 40851-NQPC carbon filter combines activated carbon and potassium permanganate to actually oxidize the air. This results in a clean, odor and contaminant-free air stream.

To ensure optimal odor control, replace the carbon ring filter in your NQ Clarifier air purifier every 24 months (18 months is recommended).
