There are all sorts of products being sold as allergy control products now days. Some work great and many are just hype. Do your homework. Talk you your friends, doctors and companies that have been selling the products. Ask them what worked, how fast, what did it cost, easy or hard to use.
Have a friend that bought several air cleaners while living in London and even though they were rated #1 she thought they were junk. She now uses Austin Air Healthmates and loves them. Plastic vs metal??
Here is a fairly good article about how some of the allergy control products work.
Enjoy
