20x21.5x1 Air Filter
Filter King 20x21.5x1 air filters protect your home by cleaning out incoming airflow free of harmful irritants. The airflow in your home is constantly coming through your systems, but they have no way to tell the clean air from the dirty. AC and furnace filters are made of a tight mesh weaving that allows airflow to pass through naturally, while particles are captured and absorbed. The process cleanses the airflow, but the filters become dirtier over time and cause indoor air quality to dip. Eventually, air filter replacement is required in order to keep the air coming in without any issues.
Your air filters will become covered in particles over time as they continue to capture and absorb them. The dirty air filters eventually become so covered in particles that they are cannot effectively allow airflow to pass through. Without fresh airflow, the air inside your home is subjected to drying out and stagnation. Your air systems also become more strained as they try to push airflow through the blockage. The resulting effort caused mechanical problems and leads to a rise in energy billing.
Your home air filters need regular maintenance in order to keep airflow coming in smooth and clean. Filter King offers new, fresh 20x21.5x1 air filters that are installable upon their arrival. We also have air filter delivery service, along with a subscription option, where orders of two or more filters are shipped for free. Filter King model filters have a MERV rating(Minimum Efficiency Reporting Value) rating of eight and block out more than 90% of all particles less than 3 microns. Such particles include:
- Pollen
- Dust & Lint
- Mold & Mildew
- Fine dust & other dust particles
- Fumes & Odors
- Dust Mites
- Bacteria
- Smoke
- Viruses
- Mold spores
- Allergy, asthma, and other airborne particles
Furnace Air Filter 20x21.5x1
Your AC and furnace filters work in the system to clean heated airflow before distribution into your home. Your filters will continue working until they become dirty, and at this point they become a problem that needs addressing. Heated airflow needs release, or the furnace temperature begins to rise to a high degree. If the temperatures are too high, then the furnace may become damaged and require some expensive repairs. Your home will also see temperature fluctuations when the heated airflow is not able to warm its rooms. Order our new high-quality filters today and keep airflow coming in through your systems without issue.
