Review on RENPHO Large Room Air Purifier for Bedroom - Up to 720 Ft², True HEPA Filter Intercepts 99.97% Dust, Smoke, Odors, Allergens, Pet Hair - Quiet 26dB, CADR 170m³/h by Lynn Hans

We stayed at a friend's house in the mountains with an air purification system and found my allergies didn't flare up overnight. I already bought a Renpho body weight scale in January and I really liked this product, so it made sense to try the Renpho air purifier. I have a little over a week now. Cat and dog dander no longer irritate my sinuses in the bedroom every night and I sleep incredibly well. I think replacement filters priced under $20 each are quite reasonable for this level of filtering. Highly recommended!
