Are air purifiers as strong as a fan?
Right now I’m thinking of buying the 0 or so HEPA type air purifiers. I would like to get an air purifier for my apartment, but want to know if they can double as a fan. Do they usually blow like a fan as well, or do they just purify the air without the breeze? If not, are there some you can think of that blow as well as purify? Which ones can you guys recommend?

The purpose of the air purifier is to process all the air in the room, which means it has a blower fan and the air must move. The problem with moving air is it creates noise, so the manufacturers of the air purifiers must move the air as effectively as possible without making too much noise. The result is a high volume of air being moved with low velocity or speed. Usually, you want high velocity for a cooling fan, since it is the breeze that makes you feel cooler. So, don’t expect to get cool from your air purifier.
If you want my advice on an air purifier, buy one that works. Take a look at the Sun Pure units at http://www.smoke-eaters-supply.com/home-smoke-eaters.html These are the units used in hospitals for their efficiency and effectiveness. I hope this helps.
