Okay, whats a CADR?
We mentioned CADR earlier, and it is the most important rating to look for overall. It stands for Clean Air Delivery Rate, and is exactly what it sounds like it tells you how quickly it will circulate clean air throughout the room, filtering all of the air through the filtering system once. Currently, twenty-nine manufacturers of air purifiers list their CADR rating on their packaging so that you can easily compare them to each other.
You should look for an air purifier with a CADR number that is equal to about two-thirds the size of the room you will be using it in. For instance, if you have a 10 X 15 room (150 square feet), then you should get a purifier with a CADR number no less than 100.
If you get a rating higher than you need, you will simply have your air cleaned even more quickly and efficiently, but if you get a rating lower than recommended, the efficiency wont be there and the air purifier will struggle.
There will actually be three CADR numbers: one for pollen, one for tobacco smoke, and one for dust. For the best results, use the number for tobacco smoke, which is the smallest particulate in the ratings system.

The cost of air purifiers can vary widely, and its a bit surprising to note that you cant always judge the value of an air cleaner by its cost. There are several things to consider when you buy one that will impact your decision. While you may pay less for one over another initially, operating costs and accessories can add up over time, making some systems much more expensive in the long run.
Filters If you choose an air purifier that uses paper or fiber filters that are disposable, be sure that they are HEPA filters. These are 99.97%
efficient for dust and mold spores and well worth the cost. Anything less is throwing money away. Also check to see if you can order replacement filters in bulk for a discounted price.
Plates An air purifier with cleanable plates may cost more initially, but figure out the cost of filters over a few years time and compare. Will you save money by paying more up front and cleaning the metal plates rather than worrying about the filters?
Operating Costs Always try to find out what the estimated operating costs will be. What does the manufacturer estimate the monthly electrical usage will be? Will the air purifier run constantly or will it cycle?
Extras If you have someone in your family who is particularly sensitive to environmental changes, such as a migraine sufferer, you may
