What We Look For In Air Purifier Reviews

For each purifier that we review, we look at the following points:

Air-Purifier-Reviews

1. Make sure that no gas leaks [this includes ozone]

2. Check that the filtration process is up to HEPA industrial standards.

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

4. How easy will it be to fix yourself? Can you replace parts and filters easily?

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

6. How noisy is the machine when it’s running?

7. What level of trust do we have for the company? Do we trust the returns policy?

8. Is the price fair for what you receive?

9. Have customers made complaints about the purifier?

10. Is the design attractive?

Using this guideline we find that all our reviews are both fair and informative to the consumer.

Be careful with reviews that mention:

warning

1. Really positive reviews that don’t mention any negative points

2. Small review with very little detail

3. Any site or magazine that only sells on purifier as they will be biased.

If you find any of the above points in your review then we think you should not trust it.

You should combine reading reviews from sites such as air-purifier-reviewsite.com with looking at big retailers like Amazon.com and epinions.com. These big retailers allow their customers to provide reviews and will often cover most air purifiers on the market. You will find that many air purifiers have already been given star ratings at amazon and epinions.

Most sites and blogs will only review that popular purifiers from Oreck, Sharper image, Alen and Honeywell.

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

We recommend that you should always look at reviews that test the machine under conditions that you plan to use it.

Guide To Air Purifier Reviews

The Environmental Protection Agency of the United States ranks indoor air pollutants among the top five environmental health risks. Indoor air pollutants include particulate matter such as dust, smoke, pollen, animal hair, tobacco smoke, and cooking stove emissions. The home’s air can also be laden with harmful dust mites, molds, bacteria and viruses as well as the particles they produce. Gases from combustion processes (cooking, vehicles, tobacco) as well as from paints, varnishes, cleaning products and pesticides also contaminate the air. Usually, these products are easily removed by simply allowing fresh air from the exterior (i.e. ventilation). However, ventilation may be constrained by bad weather and external environmental pollution. It is in these cases that air purifiers come in handy. However, air purifiers are of all types. It is important for the customer to be able to effect an Air purifier review on his own in order to be able to make a purchase decision and be satisfied with the product. Air purifier ratings can be made using several clear criteria as follows:

1. Maximum Air Flow Rate

air-flow-room-size

While purchasing an air purifier, the size of the room should be taken into account. Under normal circumstances, the entire air in a given room should go through the purifier at least twice per hour.

2. Cleaning Efficiency

Cleaning Efficiency

This is the efficiency with which the purifier removes particulate matter. Two types of tests are done to quantify this: physical count of particulate matter in the air and Blood Agar Plate test. The consumer can gain access to performance evaluation reports of the air purifier (they can ask the seller) that detail the results of these tests.

3. Life of the filters

Most air purifiers are based on HEPA filters. HEPA filters, if operating alone, easily clogs up and needs frequent cleaning and replacement. On the other hand, if a pre-filter is present, it can remove the larger particles before the air reaches the HEPA filter, leaving the latter to deal with the smaller molecules. This prolongs the life of the HEPA filter.

4. Cost and availability of Replacement Filters

Before purchasing a purifier consider the cost of replacement filters. If they are too high, your equipment may not be economical enough to run in the long term.
