Whether you’ve noticed that your air filter is suddenly clogging faster, or you’ve always had an excessively dirty air filter in spite of following the professional recommendations, there are causes and solutions. Besides the hassle of changing filters often, a quickly clogging filter may indicate an HVAC problem that needs attention.
You have pets.
It’s surprising how much pet hair and dander cats and dogs contribute to the indoor environment. What doesn’t show up on your furniture and floors probably gets trapped on the air filter. If you have large long-haired pets or more than one, the filter will clog quickly.
Frequent vacuuming helps, but the most effective way to reduce airborne fur is to brush your pets frequently, especially during the spring and fall.
The filter has a high efficiency rating.
A filter that traps more particulates is denser and will fill with dust faster than an inexpensive filter that’s porous. As long as the filter isn’t too dense for your system, most HVAC manufacturers recommend that you use a use more efficient filters to protect the equipment.
You have leaking ductwork.
Your ductwork can develop leaks at any stage, from brand new to old. If you’ve noticed that the dirty air filter is a recent change to your HVAC system, it’s possible for the ductwork to have broken apart.
Look at the registers in each room for an excessive amount of dust, or check the air volume coming from the duct. If you suspect a leak, contact your HVAC contractor immediately. Professionals will test the ductwork and use a variety of methods to seal them completely.
Ductwork leaks waste energy by losing the air you’ve paid to cool to places where you don’t need it. They also pull in harmful substances into your home’s breathable air, which can irritate anyone with allergies, asthma, or a compromised respiratory system.
