Your Allergies and Your HVAC

Posted by at 11:12 AM

Allergies and asthma can both be triggered by indoor air pollution, which is, shockingly, usually much higher than outdoor pollution. Some of the most common indoor allergens are: 

  • Pet Dander

  • Mold

  • Dust Mites

  • Pollen

All of these can become airborne particles that trigger allergic reactions and asthma attacks when inhaled.  Unfortunately, any particle that’s capable of becoming airborne is also capable of being spread by your HVAC system.  So, what can you do?

Regular Maintenance

Because HVAC systems can easily harbor allergens and spread them every time they’re in use, it’s vital to follow proper maintenance protocols for your system.  Filters should be changed as recommended, usually at least every two months. Any maintenance schedules recommended by the manufacturer should be followed to a tee to make sure the system is running optimally. Additionally, it’s a good idea to schedule regular duct cleanings to clear any allergens and pollutants that may be getting trapped in the ductwork. 

Quality Filters

The air filter in your HVAC system plays an integral role in the air quality of the home and reducing indoor allergens.  A quality filter can trap even the tiniest of particles, preventing them from dispersing throughout the home.  Filter efficiency is given a MERV, or minimum efficiency recording value, rating ranging from one to twenty with the highest ratings offering the highest filtration levels. 

Air Purifiers

When your HVAC’s high efficiency filter isn’t cutting it, it’s a good idea to explore air purifiers.  A whole-home air purifier with a HEPA filter will pick up where the HVAC system’s filter left off, trapping allergens that are too small for the filter alone.  Whole-home air purifiers are a great idea for families dealing with severe asthma and allergies. 

Indoor air pollution can take a considerable toll on a family’s health, especially for those already suffering from respiratory issues like asthma.  Regular HVAC maintenance, along with high-quality filters and the addition of air purifiers where necessary, can help stop allergies in their tracks allowing the whole family to breathe a little (or a lot) easier.
