    Just bought number 3

    I'm running my Sans in conjunction with Honeywell 300s! My wife was making dinner and got to watch the monitoring light change colors in the living room! With three large dogs there is plenty of airborne activity and scents in the air!

    My Sans works harder than Kris Jenner

    I LOVE my sans. We moved into an older townhome back in August and noticed our air smelt weird. We also don’t have a vent in the kitchen so every time we cook our sans gets right to work to clear any smells and smoke. We received our first replacement filter since ordering the sans back in september and I am amazed! My parents ordered one and loves it just as much as we do. Truly the best purifier purchase. I am so happy!

    Sans Review

    When I first plugged in my Sans, I wasn't sure it was working correctly. I spent the first 2 weeks watching to see if the number changed and never noticed it change unless I unplugged and then plug it back in. This is an older house, so I didn't think it was working and I considered returning it. Then about a week ago, I turned on the heat when the weather got cooler and I noticed that the number went up to 18, which made it me think maybe it really did work after all. Then 2 nights ago, I was cooking ribeyes in a cast iron skillet and of course they were smoking, so I turned on my hood vent and the smoke dissipated. As the steaks continued to cook, after removing them from the skillet, I covered the steaks to allow them to rest and walked into the next room where the Sans unit was located and immediately saw that the numbers and the symbol on top of the unit were red and the numbers had shot up to 185. So now I know that the unit works and that it's working well. I'm a believer! However, I think you should have a diagram of the unit with parts labeled and more detailed instructions included with the units. There were some things that weren't clear to begin with and there is no number to speak to a representative. Sometimes it's hard to make yourself understood by only typing questions or texting.

    Yeah, I’ll be keeping it…..

    This unit is quite loud on ‘HI’ and can’t even hear it on the rest of the settings. I wasn’t sure about it as it didn’t budge off ‘005’ for the first several days, then when we started pulling the pillow cases and sheets off the bed it went to ‘021’ in red, then 20 minutes later was back down to ‘005’. My wife and I both had covid last year/first part of this year so we wanted one and so far, we love it (after two weeks)...
