LOVE LOVE… I didn’t think I had indoor allergies until I bought this purifier. My nose was always drooling using tissues all day long. Those days are gone with this purifier. Sneezing attacks, usually 6-8 sneezes at a time are gone. Husband says his stuffiness has improved we don’t wake up all stuffed up. Hesitant to buy, don’t be, you’ll be happy you bought it….LOVE..LOVE…buy and be stuffy free……
