A great product to eliminate unnecessary stench & odours around your cubicle in the work area that usually makes working atmosphere so difficult.

Boys breathing much better

This our first purchase of an air purifier, but when our grandsons (aged 10,8,2)moved in with us last month and 2 have breathing issues (asthma and allergy) it was time to do something. Did lots of research first before selecting the Alen. Went small at first because was not convinced they really worked as advertised. However after only a couple hours of operation the boys noticed and felt a significant difference in the air quality. They feel very comfortable now and have had no breathing problems. Will most likely purchase a larger unit or units for other rooms in the house. Thought the unit was noisy but does not seems to bother the kids so I consider it "white noise" now. Would recommend this unit to friends!

I purchased this for my son's dorm room. He has asthma and sensitivities to environmental allergies. I looked at many purifiers and did a lot of research online. This unit is of excellent quality and you can't get anthing comparable for the price. I wanted true HEPA filtration. It is so easy to use, and is very quiet. My son says he and his roommate don't even know it's on. Another important feature is that is does not take up much space on a desk or table. Only wish all filters had odor control for the price. I feel very comfortable recommending this unit.

It works great in my 200 sq ft bedroom. I only use the low fan setting, as the others are too loud and not needed where I have it. I can breathe easy at night now, even in the peak of allergy season! I bought one for my son's dorm room too, since I liked it so much.

We used this for our 5 month old daughter who had dust allergies. Within 2 days of using the filter she was less congested!

This is the second T100 I've purchased, one for personal use and now one for my business. The second one I got had a slight rattle to it when the fans are running but not enough to want to send it back. After letting it run for a few hours we could instantly tell a change in the area it was in. Great little unit that is perfect for around the desk area. I took a star off for the rattle.

wow, to be honest, i was skeptical of the all the hype from all the reviews. But, it seems they really weren't kidding about how effective the filtration is. It was delivered to my dorm, got it running and I immediately realized that I wasn't sneezing anymore.... and this was after 5 minutes of it on. And since dorms are small, the air filter is perfect for the room. Worth every penny....

This air purifier started making a difference in my air quality within a few hours. It was so easy to use - just put it where you want it, plug it in, and hit the power button! The three different speeds are also a great convenience for regulating air flow. I have bad congestion, and indoor pollutants really exacerbate that. Thanks to this air purifier I have MUCH clearer breathing! The only downside is this model is not super quiet, so I can't always leave it on at night. But the price was right for me, since I didn't have much to spare and I was looking for something small that could fit into my really small room. I've already recommended it to friends!
