Which air purifier is the best to buy?

What is the best air purifier that i can buy?

• I live in the city and there the air quality is usually pretty bad here. I am looking to purchase an air purifier that will help filter out as many of the dangerous impurities in the air as possible. I have about a $300 budget, any recommendations on what make and model that I should purchase?

• Answer:

  I absolutely love my Austin Air machines. I own several. When my kids moved out they took theirs with them, so that is the same model I purchased again. If you are looking for something for the bedroom, the make a Junior model. That is what I put in my kids rooms. I like Austin because they last and last and last. You only have to change the filters every 5 years. One of my units is over 10 years old. The plastic junk like Honeywell just doesn't work as well or last. I'll give you a link to an article that tells you how to evaluate filters, a web site that rates the filters, and a place that sells the one I have. I highly recommend Austin Air
