Worth it, if you don't mind the noise
I have been dealing with asthmatic bronchitis since October. I finally decided to buy an air purifier. I found this and I took it to work. In my office I couldn't hear it. My 3 year old son got sick and I brought it home and put it in his room. I'm never taking it out of his room. He has always suffered with congestion and allergy medicine hasn't always made a difference. After two night in his room he has been sleeping much better and doesn't cough like he used to. The machine is very noisy. It's a loud white noise like your furnace noise. My son sleeps right through it and it seems to help keep him asleep because he doesn't hear much else.<br />My mom decided she liked it and tried it in her bathroom. She now owns her own purifier. Her bathroom smelled like mold and it helps take care of that smell. My dad has had surgeries so now his bowel movements are horrendous. This purifier has made a huge difference in diffusing that smell and my dad isn't as self conscious using the bathroom any more. So they now have their own. I bought another one for my work and I have bought a few more larger purifiers for the house. All of these have made a difference for me. The house isn't as dusty and I feel better.
