Rating An Air Purifier---5 Easy Ways to Rate An Air Purifier's Effectiveness

Trying to find the best air purifier for your situation can be confusing and frustrating. But there are certain constants that every cleaner needs to have to work well for you. Take this check list of 5 features with you in your search and you will be surprised at how much easier rating the purifiers will be. Choosing a cleaner with these features will insure that you bring home the best one for you and your family.

Four Filters---The more filters a cleaner has the better it will be able to remove airborne pollutants. Units that have one or no filter will need frequent maintenance either through washing and cleaning something inside; or they will require frequent purchase and replacing of the filter. Either way, this is valuable time lost for you and down time for the unit when it is not cleaning your air.

The most important type is the high efficiency particle arresting (usually shortened to HEPA) filter. This technology continues to prove itself to be best at removing particles from the air. By definition this filter is required to be able to remove 99,997 out of every 10,000 airborne particulates that are.3 microns or greater with a micron being defined as one millionth of a meter. This means it is able to remove normal household pollutants such as dust, dust mites, pet dander, mold and mildew spores, and seasonal irritants such as pollen.

Your cleaner should also contain a carbon filter because it has proven best at removing gaseous pollutants such as smoke, chemicals, and odors. Having both types of filters in the unit means that one cleaner is able to take out multiple types of pollutants.

A large and medium particle pre-filter will catch large and medium particles that can be seen with the naked eye. These include particles like pet and human hair, dust, and lint. These filters save the HEPA filter for the microscopic particles and prevent if from becoming clogged with big particles that the pre-filters can remove.

Variable Speed Options---When the unexpected happens, you need the ability to clear the air faster. Being able to choose the rate at which the air is cleaned is invaluable when life happens. High, medium, and low filtration settings will give you the most control.

Steel Housing---Units made of plastic often off-gas fumes from the plastic when the motor heats up. Steel insures that when the motor gets warm, it will not produce obnoxious fumes. The last thing you want to do is to pay money for a cleaner that puts more pollutants into your air. Steel casing insure that the only by-product will be fresh clean air.

24 Hour Coverage---In order to keep indoor air quality high, pollutant levels need to be kept low. The only way to do that is to continuously filter the air. Your purifier needs to be able to run 24 hours a day safely, efficiently, and effectively. Don't settle for less.

Pro-rated Filter Warranty---One of the best ways to tell whether the filter will last is to look at how long the manufacturer will guarantee it to work. A 5-year prorated warranty on a filter lets you know that the company is serious about the filter lasting and is willing to pay if it doesn't. That kind of guarantee almost insures that you want have to use it.
