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?

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.

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!

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!

I really love this product...example..I… I really love this product...example..I was telling my sister how well it automatically cleans the air, when my son came home from work , took his work boots off and set them beside the Sans...long story short..the machine went bezerk...blue light turned red and fan turned up on high..when the laughter from all subsided he decided he should clean his boots before coming in the house..lesson learned..well done Sans....well done :)
