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!

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?

Buyer Beware This is not True Sans, would you like to see a copy of the transcript conversation? I still have it. I replied back within minutes with the recording, which showed the problem in both machines. John didn't address the first issue at all. Of the second SANS unit issue, he only said not to worry as the warning light would probably come on in a few days to a week. When I pointed out I had changed the filters once before and reset both lights at the same time. So they both should have come on together or at least a week apart, that's when SANS stopped talking. Oh SANS don't you wanna talk anymore 😂 _____________ I purchased three units and they work decently. Not as great as they claim but it definitely helped with my allergies to an extent. Then I started experiencing minor problems with two of my units. When I brought the problem to the companies attention, the company line was, "This has never happened before." When I pointed out there is always a first they stopped talking. Decent product Really bad customer service. The reason you don't hear the negative is bc they block all bad press.

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.

Best customer service experience of whole pandemic! I have never ever when ordering online received such responsive and throughly helpful customer service I have now added 2 Sans to our home health team! We have 2 hairy big doggies 4 family members that are human and also drag a lot of the outside indoors unintentionally as we are all huge outdoors periods all year long. We are excited to ha e a way to tell the air quality and love that we can see the numbers improve as the machines do their invaluable jobs bringing the level of pollutants down and cleansing the air we breathe at home Pure pleasure to have had such an comprehensive walk though via text with a rep for set up and to answer our many questions about why Sans Happy healthier home!
