PuroAir distinguishes itself by using a grade HEPA-14 filter, which removes 99.99% of particles everything from fine dust and pollen to pet dander. Within just a few days of running the purifier in their open-concept living area, the Johnsons noticed markedly fewer allergy symptoms and easier breathing for their people. https://www.tumblr.com/getpuroair/788034919471415296/breathing-new-life-with-puroair-a-familys?source=share #Puroairdiscount
