My SANS is working flawlessly. We bought it to keep the dust down in the house. Since we received ours, the amount of dusting has gone down. I haven’t looked at the filter lately, but it seems to be working just fine.

We enjoy everything about the Sans.

When the Roomba was cleaning, i noticed a significant increase in the particulate count on the Sans. Within 10 minutes, the air quality had changed back to a healthier level.

I was definitely skeptical at first, but Wow, after replacing the air filter for the 1st time, I was blown away with how much additional dirt/debris this thing captures. Super easy to replace, and my wife was mentioning how little she has to dust now with this thing running 24/7. Whisper quiet settings too!

So far we are loving the Sans. Auto mode detects cooking smells and its keeping our space fresh.

We have two Sans air filters, one on each floor. They both do a great job of collecting so much dust and debris out of the air. We have the autoship replacement filters in place which helps to ensure our air stays as clean as possible. Yes we still have dust but it is a lot less than we had prior to getting the Sans air filter.

Excellent

We have noticed less dust in the house since using the Sans this last month. I am allergic to dust so having these in our home has been great.

My husband and I are so impressed with the Sans Air Purifier. We not only bought the whole house purifier but also one for our bedroom. Just within the first day there was a noticeable change - especially as we have 2 fluffy cats in the house that shed. We're breathing better, the air feels cleaner, and far less sniffles. Plus, it's quiet - and I love that. Sans had everything packaged well and delivered was incredibly fast! Absolutely recommend.

One unit in living area one smaller unit in bedroom air seems cleaner. Asthma attacks have been reduced.
