HEPA Air Filter Tips
To maximize the filtration power of your HVAC system, change filters frequently and monitor its energy consumption. Higher quality MERV-rated filters may increase the filter effectiveness, but can come at the price of higher energy usage and increased wear and tear on your HVAC's systems mechanical components.
For maximum performance of your home HVAC system and to maintain energy efficiency levels, replace your filter at least every three months. Replace more often if you are introducing higher levels of particulates into your home, such as when renovations are being done. Also, consider more frequent replacements if you have a family member with asthma, allergies or another lung disease.
