    Improve Indoor Air Quality and System Performance

    Air filters are one of the simplest yet most important components of any HVAC system. They help capture dust, pollen, pet dander, lint, and other airborne particles before they circulate throughout a home or business. Clean filters also help protect critical HVAC components from dirt buildup that can reduce efficiency and shorten equipment life.

    Replacing filters on a regular schedule helps maintain proper airflow, improve energy efficiency, and reduce unnecessary strain on your heating and cooling equipment.

    HVAC Air Filters by Size, MERV Rating & Application

    Caudill Supply stocks and sources HVAC air filters and replacement filter media for residential and light commercial air conditioners, heat pumps, air handlers, packaged units and other HVAC equipment. We carry filters in many of the most commonly used sizes, thicknesses and MERV ratings for routine HVAC maintenance and replacement applications.

    Our selection includes popular MERV 8, MERV 11 and MERV 13 HVAC filters, along with common filter sizes such as 14x20x1, 14x25x1, 16x20x1, 16x25x1, 20x20x1, 20x25x1 and 20x30x1. Additional and less-common filter sizes may also be available depending on the application.

    MERV 8, MERV 11 & MERV 13 HVAC Filters

    The MERV rating indicates how effectively an air filter captures airborne particles. MERV 8 filters are commonly used for standard residential and light commercial HVAC filtration, while MERV 11 and MERV 13 filters provide increased filtration for applications requiring greater particle capture.

    Selecting the proper filter involves more than choosing a MERV rating. The filter dimensions, thickness and HVAC system requirements should also be considered to maintain proper airflow and avoid unnecessary restriction.

    Replacement AC & Air Handler Filters

    HVAC filters help capture dust, pollen, lint, pet dander and other airborne particles while helping protect evaporator coils, blower assemblies and other HVAC components from dirt buildup.
