How to Choose the Right HVAC Air Filter

The air filter in your HVAC system acts as the lungs of your home, trapping dust, allergens, and other airborne nasties before they circulate throughout your living space. But with so many filter options available, choosing the right one can feel overwhelming. Here’s a guide to help you select the perfect air filter for your needs.

Considerations for Choosing an Air Filter:

Here’s a table to help you compare MERV and FPR ratings:

MERV RatingFPR RatingPerformance DescriptionTypical Applications
1-42-3LowBasic dust control
5-84-7GoodCaptures dust mites, pollen, and mold spores
9-128-10HighIdeal for allergy sufferers or homes with pets
13-16N/AVery HighRemoves most airborne contaminants

HEPA Filters

HEPA (High-Efficiency Particulate Air) filters are a distinct category of air filters known for their exceptional ability to capture even microscopic particles. They typically fall into the MERV 13-16 range, but don’t have a designated FPR. HEPA filters achieve a filtration performance of 99.97% at 0.3 microns, making them ideal for:

It’s important to note that HEPA filters can restrict airflow more than standard filters. Consult your HVAC system’s manual or an HVAC professional to ensure your system can handle a HEPA filter without compromising efficiency.
