Where can I purchase a highly efficient air purifier with a sterilizer?
my house needs an air purifier really bad because my mom has breathing problems. she wants one that has a sterilizer and that is very strong like 2000 sq ft coverage. please help if you know any goods air purifiers and tell me the name and where I can purchase it. Thanks!

Here’s one to consider http://www.air-purifier.org/homeandoffice.html
Rabbit Air is a great purifier. 2000 sq ft is a large area you’ll probably have to get two of them and place them in opposite sides of the house.
