Air Filters And Seasonal Allergies

Seasonal Allergies

As many as 50 million Americans suffer from seasonal allergies each spring and fall. Allergies cause sneezing, coughing, and phlegm irritations. While allergies can be caused by blooming plants and household pets, there are other more insidious causes. Here’s more information about non-natural causes and how to fix them.

Causes of Seasonal Allergies

Radon gas has been known to cause allergy symptoms, as has formaldehyde, insecticides, pesticides, cleaning and personal care products. Irritants from smoking and wood-burning fireplaces can also aggravate allergies. Gasses from cooking appliances and water heaters cause allergies. Central air conditioning can worsen allergy symptoms. Cool air is transported through air ducts that are found in walls and your attic. This can lead to condensation and mold, a major irritant for most allergy sufferers.

The Cure is An Air Filter

A good air filter is your main defense against bad air quality. A Merve rating refers to a minimum Efficiency Reporting Value, and allergy sufferers need to find a filter rated at least an 8. You have to check air filters monthly and replace them every three months or sooner if they appear dirty. Allergens can be taken care of using an electrostatic filter, touted as a good choice for allergy sufferers. Other types of filters include a HEPA filter or a High-Efficiency air filter, which removes 99.97% of contaminants and allergens. You need an HVAC professional to help determine how to set up your ventilation system.

Ventilation Systems

Heating and cooling ventilation systems are found in residential structures such as single-family homes. Dust from the outside can be pulled inside the ventilation system. Ventilation is the process of exchanging or replacing air in any space because the HVAC system is supposed to filter air providing better air quality inside the home. Mold grows in a humid environment and can aggravate allergy symptoms, also leading to illness and death if you are not careful to have mold ratings at 30-50% humidity. Having a ventilation system is merely a method for ventilating a building.
