Love my Sans Air Purifiers! I have a large one upstairs and down as well as 2 mini’s for bedrooms. I can breathe better, the air smells cleaner, and I don’t have to dust very often. Before I purchased my Sans, a visible layer of dust appeared within a couple days of dusting. Now I only have to dust about once every 2 weeks, but even at that, the dust is minimal.

My mini Sans air purifier/filter is great. My room had so much dust which I was breathing in for 20 years. I have air filter and I have virtually no dusk accumulating at all. I never write reviews but this air purifier really works. I am going to purchase the larger model for the downstair of my home.

We have purchased 3 Mini Sans Air Purifiers this past month (March 2026). We board dogs. They spend a lot of time indoors and sleep in our house. Our 3 Sans Mini's have been set up for 1 week so far. Our home smells fresh, so much better! We completely vacuumed and dusted before setting them up so that we could appreciate the "no dust" feature! So far, excellent results!! Thank you Sans!

These units (one small for a room and one lg for our great room) ran when VICs were released, smoke from wood stove and recreational smoking were in the air. The light indicated the concentration intensity of suspended particulates. To validate the effectiveness, upon changing the filter elements, there was a visible greying of the outside of the filter cartridge. Runny noses without colds were significantly decreased.

I have a subscription for quarterly filter replacements. I am a skeptic regarding subscription replacements, often suspecting account churning for profit. In this case the timing was correct and well worth the expense.
