Alen T100 Air Purifier

Pros: It does the job well and it's quiet even on the highest setting.
Cons: I'm wondering how much the hepa filter is going to cost me to replace it.

I did a lot of research on the web before I decided on The Alen T100 Air Purifier. It was highly recommended. At first I thought it wasn't working because I was checking the filter every day and didn't see anything so then I didn't check it for a week or so and I saw lot's of dust and stuff on the filters. I have an allergy to dust and now I feel a big difference in the quality of the air in my bedroom. I have my computer in my bedroom so I spend a lot of time in that room and I'm not coughing and sneezing anymore. What really proved it to me was the tv screen in my bedroom had to be cleaned every few days because the dust was so thick on it. Now I hardly ever have to clean it. That amazed me!
