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!

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!

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 signed up for their auto filter… I signed up for their auto filter replacement program because I live near a landfill having a chemical reaction, so this was very important and not a one-and-done. They notified me last month it was time but then nothing showed up. Come to find out they were on back-order. I had to research it. They NEVER notified me and my machine turned to a red signal notifying me it was time. Finally, they came in and it was shipped. I live in the same state and even the same area of the state of this business (southern CA) and now I am looking at day 6 and the filter is still NOT here. I have contacted them a few times now to find out they will NEVER let you speak to a human. All communication must be done online. No phone service. Now I discovered that they have handed off the delivery to UPS which notes they can't deliver because they need a code for a gate. I have NO gates and neither does my neighborhood. So, I contacted Sans and they told me to contact UPS. I am NOT UPS's customer I am Sans customer. I still don't have the filter and I have now cancelled the program with Sans which was not easy either. The program only has a skip delivery option, not a cancel. You have to contact their online customer service yet again. I have no proof they actually canceled it. Do yourself a favor and pick a different company. My time is more valuable than this bull. Zero for customer service. The product is okay but not quiet at all if you need to run it on high which we do need to do.
