Air Filters That Improve Indoor Air Quality and System Performance


Keep your home’s air clean and your HVAC system running smoothly with quality air filters. Designed to trap dust, pollen and airborne particles, these filters help create a fresher indoor environment while supporting better airflow. Explore our top-rated options for every furnace and HVAC system at Lowe’s.


Benefits of Air Filters

  • Cleaner Indoor Air: Capture dust, dirt and allergens to improve air quality throughout your home.
  • Better HVAC Performance: A clean furnace filter promotes steady airflow and consistent temperature control.
  • Extended System Life: Reduce strain on your HVAC unit by keeping components free of buildup.
  • Allergen Control: Help minimize common irritants such as pet dander and pollen.
  • Simple Replacement: Most filters can be easily installed or changed in minutes.

Key Features of Air Filters

  • Multiple MERV Ratings: Choose from various filtration levels based on the number of particles each air filter captures.
  • Disposable and Reusable Options: Select from washable or single-use filters to match your maintenance routine.
  • Durable Frame Construction: Frames are designed to maintain shape and prevent air leaks during operation.
  • Pleated Designs: Increased surface area allows the filter to capture more particles and support efficient airflow.
  • Custom Sizes: These can fit a range of systems, including central HVAC and furnace air filter units.
  • For enhanced air purification, explore products in Air Purifiers & Accessories.

How to Choose an Air Filter

  • Confirm the length, width and thickness required for your HVAC or furnace model.
  • A higher MERV rating captures smaller particles, while lower ratings allow stronger airflow.
  • Choose filters that target allergens or odors if pets or sensitivities are a concern.
  • Compare Product Types: Pair with Air Purifiers for whole-home coverage and added air freshness.
  • Replace filters every one to three months, depending on usage and environment.


Installation Steps for Air Filters


  • Step 1: Turn off your HVAC or furnace system before replacing the filter.
  • Step 2: Remove the existing filter and note its size and airflow direction.
  • Step 3: Insert the new filter with the arrows facing the correct direction.
  • Step 4: Secure the filter panel or grille in place.
  • Step 5: Turn the system back on and check airflow to ensure proper installation.

Maintenance Tips for Air Filters

  • Swap out disposable filters based on manufacturer recommendations or household conditions.
  • Gently clean washable filters to remove accumulated debris.
  • Always check arrows before installation to ensure efficient circulation.
  • Replace sooner if you notice reduced airflow or increased dust indoors.
  • Ensure furniture or curtains don’t block air returns and supply vents.
