Using Your Heating and A/C to Combat Fall Allergies

Some of us never seem to be able to escape flu symptoms.

In the fall, we find ourselves sniffling, coughing, sneezing and wheezing from a current round of pollen, such as that from trees or fall-blooming flowers.

You cannot do much about containing allergens while enjoying pollen while outdoors, however you can do some things indoors by enlisting the help of your heating and A/C system. Replace the air filter, because if you do not change your air filter often it will not capture airborne particulates as well. Besides conditioning the air, heating and A/C systems require decent air flow to remove particulates from the filtering system, so make sure your air filter is of nice quality. Fiberglass filters are not dense enough to capture the smaller particles of pollen that may be circulating in your home and triggering your flu and allergy symptoms. Your best defense is a dense, pleated filter rated 9-12 on the MERV scale. Consider an air cleaner, as the type of air cleaner you choose will depend on the kind of allergen you want to control. Your heating and A/C unit might benefit from an electrostatic filter if pollen is your problematic allergen. Permanent filters are more expensive than disposable filters, however they last for a long time. Electrostatic charges attract particles and periodic cleaning is required. A good quality HEPA air filter may be necessary if your flu symptoms are severe enough. In order for a HEPA filter to work in your heating and A/C system, the unit must be modified to accommodate this ultra-dense filtration. As a result, the heating and A/C system would not be able to cool or heat properly, which could cost you more money in electric bills.
