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 MY NEW AIR PURIFIER!!! I LOVE MY NEW AIR PURIFIER!!! I HAVE BEEN LOOKING FOR ONE FOR A WHILE AND WHEN I SAW THIS ONE I GOT SO EXITED AND PURCHED IT. GOT IT DELIVERED IN 3 DAYS AND SO FAR I AM IMPRESSED WITHH THE QUALITY and the difference it made in our house. It is very quite and elegant looking. I highly recommend it.

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 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 :)

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.
