Tea AL

I had a severe issue with allergy. One day, I get the opportunity to use the beta version of the product. Even though it was a beta version, I found it very effective. After 1 months of use I find that there is a noticeable difference in the quality of the air. It feels fresher, smells cleaner. It's reduced my sneezing at night. Also, it works as a noise canceler for me. I use it in my bedroom...
