When we review a purifier on our comparison site, we look at the following:

1. No leakage of gass (such as ozone)

2. Make sure that the amount of particles that are filtered is up to HEPA standards.

3. Is the purifier well built or will it fall apart in a few weeks?

4. Are part easily replaced? Can you replace filters yourself?

5. Do the filters last long? How much do they cost?

6. Does the purifier make much noise?

7. Is the company who makes the unit trustworthy? Is the returns policy kept to?

8. Do we think that the purifier is good value for money?

9. Have customers made complaints about the purifier?

10. Is the design attractive?

We find that following this particular approach helps us to create a fair and informative air purifier review.

Watch out for reviews that are:

1. Highly positive or any those don’t mention any downsides.

2. Any review that is very short as its likely the tests might not be through enough.

3. A site magazine or site that is aimed at selling one type of purifier. This review will likely be biased.

Reviews that contain any of the above three points will often be untrustworthy and are not worth reading.

It is helpful to combine reading reviews at air-purifier-reviewsite.com with amazon.com and epinions.com. Using these big retailers you can find customer reviews for most of the popular air purifiers. Overall star ratings will be provided for most products so you can quickly see problem products.

Most reviewers will only target the most popular purifiers from brands such as Alen, Honeywell, Sharp, Oreck and Sharper Image.

We will recommend that new customers should go with the popular brands as its easier to find reviews, parts and replacement filters with ease.

For every review you should look for tests that involve conditions that you are most likely to use your purifier for.

After conducting different tests we found that the Oreck XL Range beat the competition in every category. Do you want more information about Air Purifier Ratings then feel free to visit our blog.
