HVAC Filters: Choosing The Right One For Your Home

thumb image

Indoor air quality in our homes is a hot topic these days, for obvious reasons – but the truth is that air quality should always be a top consideration if you want to live as healthy as possible, especially during spring allergy season.

If you have a forced air system (one with vents and a furnace rather than baseboards or radiators and a boiler), one of your most important jobs is to change its filters regularly. Simply put, a clean filter will do a better job than a clogged one at blocking the microorganisms, dander, and other allergens that will inevitably find their way into your home. As a side bonus, a clean air filter will also lower energy bills and contribute to a longer lifespan for your equipment.

What are the different types of air filters?

Air filters come in a number of types and materials, each with different capabilities and price points. Here’s an overview of basic types of air filters you’ll find at your local hardware store:

What do MERV, MPR, and FPR mean?

When it comes time to buy your replacement filter, you’ll also encounter a sea of acronyms – specifically MERV, MPR, FPR. Each term describes a system that uses numbers to describe the tightness of the filter weave, with higher numbers indicating finer filtration. The only difference among the three systems is who manufactured them.

Converting MERV, MPR and FPR values

Here’s a conversion table of MERV, MPR and FPR ratings for common residential usage (higher-valued filters are often used in hospitals and operating rooms, but are not necessary for home use):
