I was told I have allergic rhinitis and currently have a puppy. I did a deep search on finding the perfect air purifier and I am across Sans and fell in love. I have it set on automatic and I can feel the difference after two days of it running, it randomly switched to the different settings from blue, yellow and red, when it switches to red the fan goes on the highest setting until it switches to the blue or yellow setting.

No high up-front costs compared to other brands, fair amount of maintenance replacing the HEPA 13 filter every 3 months or so. Definitely worth the investment, cleaner air is a great step toward having a better quality of life. Filter takes a little adjusting and getting used to.

I kept seeing advertisements for the sans air purifier and have wanted to try an air purifier to help with allergies and dust. I have 4 pets also and the pet hair was crazy! Vacuuming daily is such a pain! I broke down and spent the money! Well worth it!!! Been running for about 3 weeks now. My husband no longer has nightly sneezing fits and pet hair barely any!!!! I am so happy with this purchase!
