Wildfire, tobacco, and cannabis smoke have three things in common: harmful ultrafine particles, VOCs, and lingering odor. When it comes to the microscopic size of smoke particles, we recommend an air purifier with powerful filtration technology. Our True HEPA Filtration removes 99.99% of smoke and ultrafine particles as small as 0.003 microns in size while our Carbon Filters effectively reduce smoke odors and VOCs.
