What Causes Indoor Allergies and How To Prevent Them

 

Furnace filters and air conditioner filters act as very effective tools for containing indoor allergens. Furnace filters and air conditioner filters can help prevent asthma and hay fever which though categorized as outdoor allergies can also be triggered indoors during the pollination season when ragweed and other types of pollen grains become airborne and are carried into homes through windows and other openings in the house. During these times, simply remaining indoors does not necessarily provide safety from allergic attacks of hay fever and asthma. Hence, there is a pressing need for ways and means to remove these allergens from indoor air to improve indoor environment and air quality. However, the potential cause for indoor allergies remains to be house dust.

What exactly makes up house dust? No standard list can apply to house dust in every house. It would in fact depend on the age and the type of a home, the humidity and temperature inside, what is found inside (for example clothes, furniture, types of food items) and the living beings/things in the home such as people, pets and plants. It is impossible to prevent the existence of dust inside a home regardless of the level of cleaning. House dust consists of an airborne mixture that may contain fine soil and plant material particles either from outdoor or indoor sources, human skin flakes and pet dander and hair, mold spores, dead insect fragments and their waste, dust mites, fabric fibers, food particles and other type of debris. Dust mites and their dropping account for the major part of house dust and are placed high on the scale as allergic reaction triggers.

Unlike seasonal outdoor allergies, indoor allergies usually exist all the year round as the symptoms persist as long as there is exposure to allergens. This poses a much bigger problem. This is why it becomes extremely important to use furnace filters and air conditioning filters to remove indoor allergens to make indoor air quality healthy and safe.

There are many things that can be done to check and weed out indoor allergens. The best way would be to remove the source of the allergen whether pet or plant, and then to initiate way(s) for the removal of maximum allergens from indoor air. The first may not always be possible. Best would be to install air cleaners along with installation of suitable furnace filters and air-conditioner filters as an allergy control measure and let the HVAC system support trapping allergens.

When indoor air re-circulates through the HVAC system fitted with furnace filters on the induction side of the furnace, and furnace filters with a MERV rating of 8 or above, help trap and retain dust, dust mites, skin flakes, pet dander, mold spores, pollen grains and other allergens letting clean air circulate through the house. Installing air cleaners with HEPA filters in rooms such as nurseries and bedrooms can help trap other bacteria and viruses in the rooms. Some of these particles are so small they escape the furnace filter or air conditioner filter.
