Nice, quiet unit I have not had the product long but so far I like it. It’s incredibly quiet and I believe I notice a difference in the air quality. I like the variable fan speed and auto options. I did not rate 5 stars because I am disappointed that I can not replace the UV-C bulb. From my understanding, UV-C is only effective for a limited number of hours. I was told by their customer service that the bulb would last 7 years. Is that 7 years of continuous use? How many hours before the efficacy wanes?

Poor customer service I have been on hold for customer service for 28 minutes and then hung up. On the talk icon on the website I have waited for 30 minutes after entering my question and then disconnected.

The BEST! Ever since I became a mom I became aware of the potential toxins that we breathe everyday in our own homes. It has been my mission to to my sons environment as clean and non toxic as much as possible. I began researching air purifiers and have tried NUMEROUS brands. I invested in a high quality air quality monitor to measure vocs, etc and let me tell you NONE of the purifiers that I've used have give me a consistent green light on my air quality monitor than SANS after using it for a couple of weeks. I can feel and smell a difference. If your a concerned mom or anyone just looking for something to give you good quality air, look no further. This is the one, I promise you!!! I only wish this was invented sooner!! Thank you Sans!

I've left an earlier review and as an… I've left an earlier review and as an additional piece of information, buyers need to be aware that they need to save the box and all packaging if they want to return the Sans for a refund. I was confident after reading so many glowing reviews and I didn't save the packaging. I'm out of luck. Additionally, the company has deleted my Facebook review. I'm very suspicious of the 5 Star reviews on their site.

I love my Sans! I love my Sans!! I have multiple health issues. Finding something that actually helps me is a real blessing!! My cat and I both breathe much better now.
