We use this product in our bedroom and see a noticable dust reduction. I plan to purchase one for our computer room in the future.

I bought this to help out with allergies in my grandchildren who are coming for the holidays and have a challenge with pet dander. I have been using for 2 weeks and I myself already notice a difference in the air quality.

The T300 is very quiet and has indicator to show when the filter needs to be changed. I tried the T100 which is smaller for my daughter's room. It was a big disappointment so don't waste your money on it.

The Devil is in the Detail

After research we purchased five T300s. They do a nice job when they run but the cost to operate out weighs the performance. We have two units that are basically dead after a year of constant running. The cost and hassle to return them is too much to deal with. If we fix them we would be on the hook for more lights and filters. On high the units are a bit noisy. We also had bad lights that did not last but a few months. I give Alen credit they replaced the lights but after a few more months the year was up and the lights failed again. Lights are $59 each and good filters are costly. If you buy lights and filters twice you can just about replace the unit. The main problem other than questionable quality is the cost to operate. Do some math and see what the costs to operate will be.
