Airversa True HEPA PRO Replacement Filter Set (99.99%) for AP2 Purelle

Over the past two years; my two Airversa Purelle air purifiers have maintained clean breathing air in my home every day, working extra hard to combat exterior pollutants during the Canadian Wildfires of 2023 that brought dangerous AQI levels to our city, and throughout our recent move to a new city’s heavily populated and polluted downtown. When it came time to change the purifiers’ filters, I decided to upgrade to Airversa’s newest True HEPA PRO Replacement Filter Set, which filters up to 99.99% of fine particles in the air.While the difference between the Airversa HEPA PRO air filters with 99.99% filtration efficiency and the Airversa HEPA air filters with 99.97% efficiency might not appear much different on paper, in reality, a filter that removes 99.99% of dust, smoke, dander and other hazardous particles is capturing not only more, but also smaller sized elements than a filter offering 99.97% efficiency. These even smaller particles are considered more hazardous to human health as they are too small to be trapped by our nasal system’s natural filters. This allows smaller particles to more easily reach our lungs, and in turn our bloodstreams, which can create a risk of impact on health. Living with multiple pets in the downtown of a large metropolitan area, upgrading to more powerful air filters that capture more of the hazardous particles present in the air that enters our home was a no brainer.After understanding how much the HEPA PRO filters benefit the my home’s air quality immediately gave me an impression of lighter and cleaner air after swapping out the old filters, but the substantiated proof came shortly thereafter while cooking, when the smoke from a fry pan’s high heat sent the air purifier’s PM2.5 sensor levels soaring. The subsequent speed at which the new HEPA PRO filters tackled the high PM2.5 levels and brought them back down into single digits was noticeably faster than the previous filters, bringing me peace of mind that my new Airversa HEPA PRO filters will continue to protect the air inside my home — at an even higher rate of purification.

Great ! Last long ! Worth the price .
