Some of us never seem to be able to escape dust irritations.

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

You can’t do much about containing allergens while outdoors, but you can do some things indoors by enlisting the help of your heating, ventilation and A/C system. Replace the air filter, because if you don’t change your air filter often, it will not capture airborne particulates as well. Besides conditioning the air, heating, ventilation and A/C systems require very good air flow to remove particulates from the filtering system. Make sure your air filter is of high quality as fiberglass filters are not dense enough to capture the smaller particles of pollen that may be circulating in your home and triggering your dust irritations. Your best defense is a dense, pleated filter rated 8-12 on the MERV scale. Consider an air purification system, and the type of air purification system you choose will depend on the kind of allergen you want to control. Your heating, ventilation and A/C unit might benefit from an electrostatic filter if pollen is your allergen issue. Permanent filters are more fancy than disposable filters, but they last for a long time. Electrostatic charges attract particles and periodic cleaning is required. A true HEPA air filter may be necessary if your dust irritations are serious enough. In order for a HEPA filter to work in your heating, ventilation and A/C system, the unit must be modified to accommodate this ultra-dense filtration. As a result, the heating, ventilation and A/C system would not be able to cool or heat sufficiently.
