Air purifier comparisons are not always as accurate as you might think!

At first sight you might think that it is easy to do air purifier comparisons, but then we forget that there are many aspects to air purifiers that are important. For that reason most air purifier comparisons are a waste of time, because they fail take all these important criteria into account.

So what should you look for in a good air purifier comparison?

Well, it should at least answer the following questions, and put these answers in a table for every air purifier reviewed, so that it indeed is possible to compare apples with apples.

Does the air purifier comparison categorize the air purifiers by the quality of air that they generate? You can not compare an air purifier that has been designed just to get rid of some pollen, with one that gives people relief from serious allergy/asthma problems. The latter air purifier will be far more expensive, but will also have a far more positive impact on indoor air quality.

An air purifier comparison can not compare whole house air purifiers with room only air purifiers. Whole house purifiers are generally more expensive, and are not as effective as room air purifiers. They could actually be a cost effective solution if you want to have reasonably clean air in every room, but don’t have a need for top of the line air purification.

Air purifier comparisons should state the CADR - Clean Air Delivery Rate - for every air purifier reviewed. It is a very useful measure because it will allow you to work out the cost per square feet that is purified, and them on that basis.

Most people would like to know how silent the various air purifiers are. Preferably the air purifier comparison states the amount of noise in decibel at the lowest and highest setting, or at least contains a subjective comment.

For many the best air purifier is inexpensive, and has low operating expenses, so the air purifier comparison should state:

• the likely purchase price,
• the cost of any replacement parts, especially if HEPA filters need to be replaced, as they are quite expensive, and
• electricity consumption.

Finally, a good air purifier comparison details the warranty on the units involved and any filters.

To date we have not found an air purifier comparison that actually lists all the above details.

So what to do?

A good idea would be to first familiarize yourself with the various cleaning technologies. That puts you in a position where you can make preliminary decisions on the above categories, so that you end up with a description of what the required features are.

This narrows the field considerably, and because you can do the research on the internet it is not too hard to compile an air purifier comparison table that is relevant for you!
