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: I bought the T100 back in 2008 for my son who has dust allergies. It's worked well, and using a Kill-A-Watt, I found that leaving it on 24/7 on low costs something like $1/month. Last week, the fan got pretty loud, sounded like it was loose or a bearing was shot. I took it apart to see if I could fix it, then couldn't find my graphite powder and decided to check the warranty on Alen's website. Lifetime?? No way.
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.
Summary: I've been using this air purifier in my room for several years and it's still working fine. It is very quiet at the lowest fan setting. Even at the highest setting, it is not as loud compared to the other air purifiers being sold in the market. I mostly use it at night time and could tell the difference when it is not used in the room.
Summary: I purchased this item plus replacement filters at a total cost of just under $200. It is quiet and does clean the air well. Placed in my bedroom, I noticed that it did help with my pet allergies. However, after 9 months it started emitting a loud screeching sound, and can no longer be used. I am now going to spend the money for a Rabbitair purifier, which some of my friends recommend.
Summary: I bought this desktop air cleaner for my office and hoped that it would help with the airborne dust in the place. My allergies have been affected on a daily basis in spite of the nightly cleaning my building provides. Unfortunately, this product did nothing to improve the situation. The air quality is exactly the same and my allergies haven't lessened any. There has literally been no change at all except for a little air blowing out of the unit.
