11.5x21x1 Air Filter

Filter King 11.5x21x1air filters create an active layer of protection for air systems to help keep airborne irritants out of your home. Depending on its location, your home may be subject to a full range of airborne pollutants and allergens. Your home’s indoor air quality suffers over time if the incoming airflow is not filtered properly. This is where air filters come in, the tools clean up airflow so that when it comes in all it brings is freshness. The filters themselves become dirty in the process and will inevitably require replacement.

The air filters in your home become dirty over time and when they do that becomes an issue for your entire home. Airflow cannot properly travel through dirty air filters, which deprives your home of fresh air. The dirty air filters will also cause problems with their accompanying air systems by creating a rise in energy usage. The electrical spike a system undergoes affects your home’s billing and causes the mechanical parts of your air systems to wear down faster. The problems that come up only make it more important to replace your dirty air filters as soon as possible.

Filter King offers new 11.5x21x1 size air filters that are easily installed in any accompanying systems. The new filters will allow airflow to pass easily while also protecting your home against irritants. Our 11.5x21x1 size air filters have a rating of eight on the MERV (Minimum Efficiency Reporting Value) scale. The filters are capable of blocking irritants like:

  • Pollen
  • Dust
  • Mold
  • Dust Mites
  • Bacteria
  • Pet Dander
  • Smoke
  • Viruses
