If you are going to do some air purifier comparisons, there are some definite areas you should look at before making a choice.  Most people tend to do air purifier comparisons based on price.  Price is definitely one thing to look at, but by no means should it be the only or main consideration.

Air purifier comparisons can be difficult for consumers because the terminology and the "world" of air purifiers is confusing.  How many people use the word "electrostatic precipitator" on a daily basis?  Our guess is not many.

So, we've assembled a list of things to examine when doing any air purifier comparisons.  We've ranked these in order of importance as we see it.  Granted, some people may find other areas to be more important.  That's fine, this list is presented merely as a starting point for some things you may want to consider.

There you have it.  People may argue that the order could be different or that other factors need to be added.  But any serious air purifier comparison takes all of these things into account in one way or another.
