Furnace & HVAC Filters

Air filters remove dust, debris, and particulates from the air moving through a furnace or HVAC system, protecting internal components while supporting indoor air quality. A clogged or incorrectly sized filter can restrict airflow and reduce system efficiency.

Furnace Part Source carries a selection of furnace and HVAC filters in standard sizes and MERV ratings for residential and light-commercial equipment.

Common Filter Types We Carry

Common filter options include:

  • Standard pleated filters for everyday dust and debris capture.
  • Higher MERV-rated filters for improved filtration of finer particles.
  • Equipment-specific filters sized for particular furnace or air handler models.

How to Find the Right Filter

Before ordering, confirm the exact filter dimensions (length, width, and depth) either from the existing filter or the equipment's filter slot. Also check the recommended MERV rating for your system, since some HVAC equipment has airflow limitations that restrict how high a MERV rating can be used.

For best fit, compare:

  • Filter dimensions (length x width x depth)
  • MERV rating
  • Airflow direction arrow on the filter frame
  • Equipment model, if using an OEM-specific filter

Replacing Your Furnace or HVAC Filter

Regular filter replacement helps maintain airflow, protect the blower motor, and support consistent indoor air quality. Check filters monthly and replace them according to the manufacturer's recommended schedule or sooner if visibly dirty.

Need Help Choosing a Filter?

Not sure which filter size or MERV rating you need? Check the existing filter or the filter slot in your equipment, or contact Furnace Part Source for help identifying the correct replacement.

HVAC Filter FAQs

How often should I change my furnace filter?

Most furnace filters should be checked monthly and replaced every one to three months, depending on usage, filter type, and household conditions such as pets or allergies.

What does MERV rating mean?

MERV (Minimum Efficiency Reporting Value) measures how effectively a filter captures particles. Higher MERV ratings capture smaller particles but may increase airflow resistance, so confirm your system supports the rating you choose.

Can a dirty filter damage my furnace?

Yes. A clogged filter restricts airflow, which can cause the system to overheat, reduce efficiency, and place added strain on the blower motor and heat exchanger.

Which way does the airflow arrow on a filter go?

The airflow arrow should point in the direction air travels through the system, typically toward the blower or air handler. Installing a filter backward can reduce filtration efficiency.
