The BEST! Ever since I became a mom I became aware of the potential toxins that we breathe everyday in our own homes. It has been my mission to to my sons environment as clean and non toxic as much as possible. I began researching air purifiers and have tried NUMEROUS brands. I invested in a high quality air quality monitor to measure vocs, etc and let me tell you NONE of the purifiers that I've used have give me a consistent green light on my air quality monitor than SANS after using it for a couple of weeks. I can feel and smell a difference. If your a concerned mom or anyone just looking for something to give you good quality air, look no further. This is the one, I promise you!!! I only wish this was invented sooner!! Thank you Sans!

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!

If you go on the web Sans isn’t even… If you go on the web Sans isn’t even listed on the list of best air purifyers. For this reason I’m out. Not into scamming

Works great Works great, the sound set on medium is peaceful. I like that you can watch the numbers go down as the air gets cleaner.

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?
