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!

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!

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!

Poor customer service I have been on hold for customer service for 28 minutes and then hung up. On the talk icon on the website I have waited for 30 minutes after entering my question and then disconnected.

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 👍🌈
