I have two Alen air purifiers that run 24/7. I never have to worry about up-keep because my filter replacements arrive just on time and I pop them in, no keeping up with when a new filter is needed. The service from this company is perfect.
Pros: Good Performance, User Friendly
Cons: Loud
Concerns: Pets
Yes, I recommend this product.

Orderd the upgraded version of the filter and found it is noisy. I need to call customer service to find out why.

This product definitely delivers! I bought it for my son who lives in a very small bachelor apt. and he smokes!! It definitely
cleaned the air, including the smoke.

This filter is used in a room where cigarette smoking is a constant. The old filter was covered in a greenish-yellow residue,evidence that the smoke and nicotine were effectively being captured. Not on the walls and window. Air quality is high , with little noticeable detection of cigarette odor.

I have the T300 with odor filter in my living room and it works very well! It clears cigarette smoke odors from the air (condo hallway air comes into foyer). No complaints; easy to use and highly recommended.
