Summary: This works as advertised. I really needed one for my tiny windowless bedroom, and it has helped immensely in cleaning up the air. The first night, I was breathing more clearly than I have in years. My sinuses opened up, it was a great relief to literally breathe easy for once. People complain about the size, but really it's not so bad. The design makes it blend in stylishly.
Summary: After much research, I settled on a larger air purifier model for the company for whom I work to provide for my workplace accommodation. Because that purifier made a great difference in my abilities to breath and function at work, and because the company immediately replaced it when it malfunctioned and could not be repaired, I automatically went to Alen for a purifier to take with me on my travels.
Summary: I purchased this unit after searching for air purifiers that may help asthmatics. I have 15 month old twins and one has had numerous respiratory problems ranging from small coughs to pneumonia that had him recovering in the hospital for 3 days. Pediatrician suggested he may benefit from an air purifier so I did a little research and figured I'd try the Alen T100 before investing in a larger more expensive unit.
Summary: When the cooling was "re-calibrated" at my office recently, I began to cough and sneeze endlessly, and I went through boxes and boxes of tissue. Co-workers also showed signs of discomfort, and I figured it was more than just seasonal allergies. I bought this unit based on reviews and ratings and from the moment I plugged it in and turned it on, I found relief.
Summary: Item does what it said it would do. I like the three different settings for speed of air movement and that you can turn on and off the ionizer. It's very quiet on the low setting. We noticed a difference in the air quality right away in our 12x12 office. You walk into to the room and you notice the difference. I would recommend this product. I am considering purchasing a larger model for my home.
Summary: My wife has allergies and we recently pruchase an air purifier for our bedroom. It was a Alen product and it has worked quite well for her. For this reason we recently purchased a smaller Alen T100. Orginally we were going to use it where we keep the cat litter box (for obvious reasons), however, my wife has decided that she had to have it for her office. So now the T100 sits in her office, making the air smell fresher and taking the allergens out.
