It is quiet and energy efficient It is quiet and energy efficient. There is no noticible rise in my electric bill. I keep it on auto, 24/7, and that is perfect for me. I have allergies and the sneezing is significantly reduced from several times a day to just two or three. Living in a split level home had me questioning if it would work well, but it fulfills it's duty to clean the air. Love it!

I made a request for a missing part I made a request for a missing part. Several months later I still dont have it. POOR service

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?

I have extreme allergies and I can… I have extreme allergies and I can immediate feel the difference in the air quality. I also like that it is easy to move from my bedroom to the main living area durning the day. Highly recommended

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!
