Not sure it has been long enough to give a thorough review but so far this product has been great. It is very quiet and easy to use. Air smells and feels much cleaner and fresher. We purchased it with the silver HEPA filter to help remove mold, and my allergies have been much better.
Pros: Good Performance, User Friendly, Quiet, Attractive Design
Concerns: Allergies, Bacteria/Germs, Dust, mold
Yes, I recommend this product.

I have allergies and had to improve the air quality in my office. This T300 HEPA tower air filter did the job. It reduced the amount of dust so I don't cough and sneeze so much. I replace filters every 6 months. $1/week for cleaner air is well worth it. Alen has always delivered timely and the website is easy to navigate.
Pros: Good Performance, Attractive Design
Concerns: Allergies, Bacteria/Germs
Yes, I recommend this product.

The Alen A350 is the first air purifier I have owned and there is nothing I can find about it that I do not like. Initially, the appearance and quiet operation met all expectations. On low speed I cannot even hear it which is great for sleeping. I am also impressed with its effectiveness; I no longer wake up with a stuffy nose. The air definitely smells fresher without any chemical odors. I read many reviews prior to this purchase and definitely support the many positive things they had to say.
Pros: Good Performance, User Friendly, Great Warranty, Quiet, Attractive Design
Concerns: Allergies, Odor, Dust
Yes, I recommend this product.
