Westinghouse Air Purifiers Remove:


Smoke - 99.72%

Smoke in all its forms is dangerous to our lungs. Most air purifiers can't trap gaseous pollutants. Westinghouse removes up to 99.72% of Respirable Suspended Particulates (Smoke). Prepare for wildfires or trap kitchen smoke.

"Like how this unit has a thing sleek design. Runs quietly in sleep mode and regular mode. The air quality produced by this unit is truly “a breath of fresh air”. Really like this unit and am so glad I bought it!!"

- Monica 

Pet Odor - 99.9%

Cleaning pet hair is one thing, but odors are small particulates in the air that can be difficult to trap. Only true HEPA and activated carbon filters trap odors. Westinghouse uses both, plus NCCO technology to sanitize up to 99.97% of harmful air and odors

"This machine (bought three med. size for entire house) is quiet, easy to set up and move around, if needed, great white noise on EC for sleeping at night. Have a large dog and no more doggy smell as before. Room smells fresh and night time allergies/sniffles are gone! Like that it is simple to operate-no programs to set up. Very satisfied with all three that I bought!"

Germs, Viruses & Allergens - 99.99%

Most air purifiers trap bacteria at best, but Westinghouse neutralizes and eliminates up to 99.9% of germs, viruses, bacteria and fungi (verify that’s the correct figure) to keep your home safe. Only True HEPA (like those in Westinghouse purifiers) filters perform at this level. 

"We have a dog and I suffer from seasonal allergies. After 3 days with this in my room, I woke up with little to no congestion. I went from taking over the counter allergy meds daily to MAYBE 2 days a week. I move it into my room at night and into the main area if the house during the day. Put it on Eco mode at night if in your room on a low setting. Great product!!"

- Lisa

Finally, An Air Purifier That Sweats The Small Stuff

Most other air purifiers simply don't have the technology to handle smaller compounds like carcinogenic chemicals in the air (a.k.a. VOCs):

- Benzene,

- Ethylene glycol,

- Formaldehyde, etc

- Odors

- Fine smoke particles.


You can see for yourself that Westinghouse's NCCO technology can handle it.
