To get all the information that you need, you might think that it is a good thing to go through the internet. Instead of doing this, just pop over to the house of a friend and check out how his airpurifier is working. He will be able to tell you all plus and minus points and also advise you on the correct brand and capacity that you might require for your own home. Therefore, forget about the internet for some time and do some reality checking on an air purifier before you decide to buy one.
