While it’s almost always better to choose products that are reusable instead of disposable to keep the planet healthier, it’s not so with most washable air filters for your HVAC system. The air filter you use for your system affects its energy consumption, dependability and durability.
The differences between reusable and throwaway filters might be hidden to the eye, but over time, your HVAC system might show the signs, which include:
- Higher repair costs. Reusable filters aren’t as dense as disposable filters, which let smaller particles enter your air handler. They may only catch animal fur and human hair, along with lint and larger dust particles.
The remaining particulates, including dust mite waste, mold spores, animal dander and pollen will pass through. When these smaller particles get inside the air handler, they’ll land on the parts and act as insulation.
Heat builds on the parts, which is one of the most common causes of reduced component life and system breakdowns.
- Poor air quality. Since the smaller particulates will circulate through the air, your indoor air quality will suffer when exclusively using washable air filters in your home. Family members who suffer from allergies or asthma will experience more discomfort.
- Mold growth. Reusable air filters have to be washed to remove the particles on them. If they’re replaced with any kind of moisture inside them, they can support mold growth. Some types of mold are harmless, but others may precipitate a health problem in sensitive individuals.
When you’re choosing an air filter, check your owner’s manual or contact us contractor for the best type to use. One the filter becomes too dense it will slow the airflow through the system too much, and one that’s too porous, like reusable filters, won’t trap small particles that eventually will harm the equipment.
The money and materials you save using washable air filters may not have a positive effect on the environment or your budget if they result in higher costs associated with repairs or your health.
