Get 14x14x1 Filters with Guaranteed Quality

When it comes to air filters, exact sizing is everything, and that’s especially true for compact sizes like the 14x14x1 air filter. A loose or undersized filter can let unfiltered air pass through your HVAC system, reducing efficiency and air quality.

Filter King solves this with precision-cut filters, made in the USA. Every 14x14x1 filter is built to spec and designed to:

  • Fit snugly without bending or gaps
  • Eliminate air bypass
  • Maintain airflow and system performance

All our standard-size filters are backed by a 30-day money-back guarantee.

Common HVAC Systems That Use This Size

The 14x14x1 air filter is used in compact return vents, often in smaller HVAC units or tight utility spaces. You’ll typically find this size in:

  • Apartments and condos with limited return vent space
  • Closet-installed HVAC systems

  • Systems from brands like Goodman, Lennox, and Carrier

  • Seal the used filter in a trash bag to contain allergens and debris.
  • Check local recycling guidelines. Some areas accept filters at special drop-off centers.
  • Avoid burning or composting. Filter materials often contain synthetic fibers and trapped pollutants.

  • Higher quality, sturdy and durable
Fiberglass Filter
Fiberglass Filter
  • Smaller surface area captures less particles
