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 👍🌈

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!

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

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!
