How to Read Air Purifier Reviews

When you try to sit down and create an air purifier review it can be really hard as every consumer needs the purifier for different things. One unit will work great for someone who has a major allergy but this same unit might be awful at helping someone who has asthma.

The task of a purifier is to remove pollutants from the air so that they don't cause discomfort or lead to an allergic reaction. A hay fever sufferer will use an air purifier to clean the air of pollen so as to reduce the risk of an allergic reaction. Another person with a dust allergy will try to use a purifier to remove dust mite allergens from the air. Certain purifiers are good at removing one type of pollutant more than other types. Taking into account the needs of different people I will try and test each air purifier in many situations and give it a mark based on the efficiency for each task.

You will generally need to use a laboratory to successful compare the efficiency of an air purifier in removing different allergens.

There is a multitude of technology that purifiers use such as UV, HEPA and even Ionizers. When you don't understand each of these technologies it can be tricky to know which is the best unit for your need. In the Navy, HEPA was first created so that air could be purified on board submarines. The way that a HEPA purifier works is by using a polymer or paper filter that has so small holes that pollutants are stopped and blocked.

At cleaning air, HEPA has good efficiency but the problem is that filters will need to be replaced. The cost of filters can be very high and in some cases can cost more than the price of an air purifier! If you are reading a review for a particular HEPA model then make sure you find out how much the filters cost and when they will need to be replaced.
