“This little thing is great, I’m not sure why the reviews aren’t better! It was the best quality ionizer I could find for the price. It is low ozone producing and doesn’t have a UV-C filter, which were both important to me. I’ve been using it for over 3 months in our bedroom and it helps with our allergies (no more waking up with puffy eyes!). It also makes the air smell/feel fresher. I want to get one for every room!”
