Was delivered as promised on time. So easy to set up and it’s been working ever since. It’s been a week and big difference in the air in our home. High allergy alert for two days this week, as soon as we opened our door to outside, it kicked into high gear. No more runny eyes and stuffy nose.

I was skeptical, but thought I'd give Sans air purifier a chance. It was easy to set up. Upon powering it on, I saw the blue ring and low numbers and thought, of course. They want you to think it's working. And nothing changed for several days, adding to my skepticism. Then I made popcorn one evening. The Sans was quick to react! Immediately, the fan went to high, the ring turned yellow, then red, and the numbers dramatically increased! Within 15 minutes, all returned to normal. This thing DOES work! Now when I cook, I see it change. I'm also noticing lest dust in my (what was very dusty) home. I'm now a believer and very happy I brought Sans into my home!

After several weeks of reading Sans reviews, I purchased the bundle. I had hopes it would help, realistically not eliminate mostly the dander, from my two German Shepherds. I still vacuum every other day with lots of dander and hair in my Dyson. But I do feel that the air quality is cleaner and my home smells fresh. Spring is the heaviest shedding season, so I’ll see what the filter looks like .
