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?

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!

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.

I made a request for a missing part I made a request for a missing part. Several months later I still dont have it. POOR service

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 👍🌈
