I was confident after reading so many glowing reviews and I didn't save the packaging. I'm out of luck. Additionally, the company has deleted my Facebook review. I'm very suspicious of the 5 Star reviews on their site.

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 👍🌈

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.

2 small sans & one large sans I wrote one review, they deleted it. I bought a small Sans for my bedroom because I have multiple medical issues. I then bought another one for an elderly man that I am caregiver to, THEN I bought a big unit for the kitchen and living room area. You advertised that the units would eliminate the dust issue in the house. It did not. The dust seems to be worse like it is just floating it around. Fraudulent advertising should be punishable with a huge fine! I've had all three now for at least 3 months. Your review tips says you want feedback and when I put my honest review, you deleted it, which is what I am sure you will do with this one.

I received my Sans air purifier and… I received my Sans air purifier and have used it non stop for five days. I can honestly say that with each day the quality of air gets better. I believe over time the air quality will continue to improve.only I really need another purifier because I move mine from room to room. I have not turned it off since I received it. It’s truly a great product so far. I wanted to wait longer before I reviewed, but I feel better already. I breathe better!! I had questions and the owner reached out immediately. It doesn’t get any better than that. It’s definitely not a product that requires a lot of reading to make it work but occasionally questions need to be answered. So with it all said, a great product and outstanding customer service, I’m looking forward to improving my quality of air.
