Asthma though very common can be fatal in some instances when a person suffers a severe attack. Patients can have an attack triggered by many allergens, the most common of which are dust, pollen, pet dander and smoke. It may sound like a difficult task to stay away from allergens as common as these around your house. But by investing in a good quality residential air filter you can reduce your exposure to these substances inside your house and thereby reduce the frequency of getting attacks. In fact the American Lung Association recommends using air filters for people suffering from asthma.

With the very wide range of air filters available in the market, what special features should you look for to satisfy your specific need?

Most air filters will purify the air and keep the air fresh, but you need something more like a Filtrete filter to filter all the miniscule particles that you may be allergic to. A High Efficiency Particulate Arrestant (HEPA) air filter is highly recommended by medical professionals for people with such allergies. A HEPA filter like the Filtrete Eureka HEPA filters will capture more than 90% of all particles 0.3 microns or larger. The particles in the air that cause allergic reactions are not smaller than 0.3 microns so you can be pretty sure of eliminating a good part of allergens with a residential air filter fitted with a HEPA filter purchased from www.yourfilterconnection.com .

High efficiency filters should not only be used in residential air filters but should also be used as your furnace filter and air conditioning filter as these will be circulating the air in your home most part of the year. Normal filters installed in these will not filter most of the smaller particles in the air leaving you susceptible to an allergic reaction.

But furnaces in older homes will not be geared for the HEPA furnace filters, if so, you can select a Filtrete filter such as the Micro Allergen Reduction filters which can capture microscopic allergens like dust, smoke and smog particles, as well as large allergens like pet dander.

Installing good quality filters in your air filter and as your furnace filter is a good start but it will not stop there. You need to make sure that they are replaced regularly to maintain the efficient filtering process. These filters should be replaced every three months for maximum efficiency.
