It is quiet and energy efficient It is quiet and energy efficient. There is no noticible rise in my electric bill. I keep it on auto, 24/7, and that is perfect for me. I have allergies and the sneezing is significantly reduced from several times a day to just two or three. Living in a split level home had me questioning if it would work well, but it fulfills it's duty to clean the air. Love it!

2 small sans & one large sans I wrote one review, they deleted it. I bought a small Sans for my bedroom because I have multiple medical issues. I then bought another one for an elderly man that I am caregiver to, THEN I bought a big unit for the kitchen and living room area. You advertised that the units would eliminate the dust issue in the house. It did not. The dust seems to be worse like it is just floating it around. Fraudulent advertising should be punishable with a huge fine! I've had all three now for at least 3 months. Your review tips says you want feedback and when I put my honest review, you deleted it, which is what I am sure you will do with this one.

Nice, quiet unit I have not had the product long but so far I like it. It’s incredibly quiet and I believe I notice a difference in the air quality. I like the variable fan speed and auto options. I did not rate 5 stars because I am disappointed that I can not replace the UV-C bulb. From my understanding, UV-C is only effective for a limited number of hours. I was told by their customer service that the bulb would last 7 years. Is that 7 years of continuous use? How many hours before the efficacy wanes?

I love it I love it. I slept so well the first night I had it on. But, where are all the explanations and guidelines for the functionality of the appliance?

I made a request for a missing part I made a request for a missing part. Several months later I still dont have it. POOR service
