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 :)

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 received my Sans air purifier and… I received my Sans air purifier and have used it non stop for five days. I can honestly say that with each day the quality of air gets better. I believe over time the air quality will continue to improve.only I really need another purifier because I move mine from room to room. I have not turned it off since I received it. It’s truly a great product so far. I wanted to wait longer before I reviewed, but I feel better already. I breathe better!! I had questions and the owner reached out immediately. It doesn’t get any better than that. It’s definitely not a product that requires a lot of reading to make it work but occasionally questions need to be answered. So with it all said, a great product and outstanding customer service, I’m looking forward to improving my quality of air.

Flashing light at the bottom of the top… Flashing light at the bottom of the top display panel would not turn off. Contacted Sans and rep instructed to hold the flashing light button for 7 seconds. I followed instructions and the light is now solid. Great product 👍🌈

Featuring and a good pick. The delivery was timely and arrived in great condition. I want to say that I am confident that the air purifier will do the job that it was intended to do , but it’s too early to tell having it only a week. Air movement is on par with other machines in its class compared to others that I have owned i.e. the Orecks but not as powerful as a Kenmore hepa or something like that. Reserving one star for experience. Good price point by the way. I recommend!
