We purchased 4 Sirena air purifiers and distributed throughout our home. They are very pretty to watch with the light colors changing while the units are on. We added the Ocean Breeze to the water and it makes the house smell very nice. Not sure how much they are filtering because the water look's clean once it’s low when we clean them and refill. They do make some noise but it is a constant sound that’s soothing and not annoying. We are very happy with the purchase.

Love these bought 4

I bought 4 of these and love them in every room and our basement. They clean the air and make the rooms smell amazing. I’ve had them for over a month and run them constantly. Additionally I received 1 out of the 4 that was broken, but after one email they quickly sent me a new one. No issues. Would like to try other products too!

From the moment I plugged it in!! Friends and family noticed it immediately and asked what it was! Ordering theirs today!

Love mine I first bought 4 then after having them in my home for three days I bought 4 more!
