Spring Allergies

Spring’s a lovely time of year when the weather is warmer, the trees and shrubs are leafing out, and we start to see some bulbs and other plants bursting into bloom. But it’s also a time when allergy sufferers brace themselves for an assault as the trees and shrubs release their load of springtime pollen.

There isn’t much you can do about spring allergies when you’re outdoors. Just take your allergy medication or get some shots from your allergist. But indoors, it’s a different story. Your HVAC system can actually help you control allergens in your home to alleviate spring allergies.

How the HVAC System Helps Control Allergens

Your HVAC system needs an air filter to keep dirt out of the workings. While some people choose a cheap filter that just keeps dirt out of the system, you can opt for a denser, better-quality filter that traps pollen and other pollutants. Install a filter rated 8-12 on the MERV (Minimum Efficiency Reporting Value) scale.

If you have a permanent, washable filter in your unit, be sure to wash it as the manufacturer recommends so that it will perform as it’s designed to do by trapping pollutants electrostatically.

You can help minimize the level of pollutants in your home and their effect on your spring allergies by keeping doors and windows shut so pollen doesn’t get inside. When you’ve been outdoors, brush off your clothes or change them immediately, putting them in a bag and washing them before you wear them again. Likewise, brush your pets off before they come back indoors.

Some homeowners find air purifiers effective in controlling pollen and other pollutants. There are several different types of air purifiers. You might opt for one that is installed in your HVAC system, called a whole-home air purifier. The filters, which are built into the return-air ductwork, trap particles as air flows through.

Portable models are also available, but they must be moved from room to room. Both portable and whole-house air purifiers use various types of media or electrostatic filters.
