This picture says it all. I have 3 dogs. My furnace filter is changed monthly. I currently replace my Sans filter every 3 months, but based on this will probably drop it to every 2 months. I can't imagine if we had been breathing all this in. Thank you Sans for keeping our air clean!

I developed CAT allergies, I rescued cats, I have 3 indoors & 15 barn cats. I take allergy shots weekly and until I bought the SANS I would wake with eye crusty, the cats would even sneeze. The Sans is on auto constantly and the first day I plugged it in it stayed on RED by the morning it was BLUE. As we walk around the Sans will change colors ....

A week in and NO MORE eye crusty and the AIR is Clear, no more particulars floating around. I bought 1 whole house unit, my living space is about 800 sqft due to 10' ceilings.

I am on the shipping list for filters.

THANK YOU for a better breathing living environment.

I always believed air purifiers seemed kind of scammy.

Paying a bunch of money to " clean" your free air.

I didn't realize how much of a difference it would make. My husband used to sneeze all the time and say he had a tickle in his throat. First week after purchase he stopped sneezing all the time and we could notice a difference in pet odor control. We have one big dog and three cats.

I'm very happy with our purchase and will continue to be a customer.
