The Best Air Purifiers for Smoke in 2023

The Westinghouse portable air purifier uses a combination of HEPA filtration and nano confined catalytic oxidation (NCCO) technology to remove and decompose airborne pollutants. Incoming air passes through an oxygen generator, HEPA filter, and NCCO reactor. In the patented NCCO process, activated oxygen particles and polluted air pass through a nano tunnel where transition metals vibrate the air, reducing pollutants to harmless materials that include carbon and water molecules.

This portable, personal air purifier is ideal for car, plane, and train travel, as well as compact spaces including bathrooms and small offices. It's incredibly quiet and weighs only 2 pounds, with a leather strap for easy transport. The rechargeable lithium-ion battery provides 8 hours of runtime per charge on low power.
