I deal with some pretty bad air due to my neighbor (duplex) I added the heavy smoke filter. I am so happy to have validation when it kicks on turbo red, after turbo purple (heavy smoke) all evening, every evening. Also, I don't have a stove fan for cooking odors and this does the job, hands down. I just ordered a T500 for my upstairs tiny bedroom that is like an oven in the summer and has no cross ventilation. I look forward to better night breathing! Thank You Alen Co for the great, ethical company you are.
Bought two 45I, to help with my allergies Love the sleek design, choose the graphic cover. Very happy so far , air feel much cleaner . The fan is pretty quiet on the low speed and acceptable when running at high speed.
After first time using in my bedroom I woke up the next morning without puffy eyes & I had increased energy. Felt like a new person. I live in studio-size stand alone older cottage. Mold is big problem, but the Allen is such a blessing and so very easy to use. I love it.
I am so excited about this Air Purifier. Within two hours of operation, It went from red to green. I now wait to see it turn to anything but green or blue, just to see how fast it cleans the air. And It is so quiet. that there are times that I don't realize that it's on. I will purchase the lifetime filters for the lifetime warranty. We are going to order another one for the upper level.

Wonderful air purifier that Alen generously donated to me as a COVID-19 front-line physician. I have more peace of mind when I come home from work knowing that the air in my home is being filtered, and sleep better with fewer allergy symptoms than I had before. The automatic mode saves energy and keeps the air perfectly clean. Thank you Alen!
