13x21x1 Air Filter

Filter King 13x21x1 size air filters are used by your air systems to clean up the incoming airflow pumped in from outside. The air coming into your home may not be the cleanest, and without filtration your air systems have no way of ensuring the air coming in is safe. Your air filters will be able to clean up incoming airflow by trapping and absorbing incoming irritants inside their tight mesh weaving. The indoor air quality of your home benefits from the clean airflow, but the filters are not capable of remaining effective forever.

Your air filters are capable of trapping harmful irritants for as long as they mesh weaving is capable of stopping them. Eventually, the weaving becomes so full of irritants that the airflow coming into your home is hindered or stopped entirely. A home without airflow sees its air stagnate and dry out, which is both uncomfortable and unhealthy to breathe in. Your home air systems will also begin using more energy, which becomes a burden on billing and creates mechanical strain for a system.

You will need to replace the air filters in your home with new ones to avoid complications throughout your systems from becoming worse. We offer 13x21x1 size air filters that are available for easy installation into accompanying air systems. Once installed, the filters are capable of effectively cleaning out airflow, they have a MERV (Minimum Efficiency Reporting Value) rating of eight. The MERV rating of a filter is the measured efficiency of its mesh weaving, our filters are capable of blocking out irritants like:

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

13x21x1 Air Filter Delivery

  • Less replacement frequency
  • Average lifespans of 3-12 months
  • Higher MERV rating 8-13
  • Higher quality, sturdy and durable
Fiberglass Filter
Fiberglass Filter
  • Smaller surface area captures less particles
  • More replacement frequency
  • Average lifespans of 1-2 months
  • Lower MERV rating 2-4
  • Lower quality, flimsy and porous

How often should you change your filter?

  • Higher energy bills
  • The air isn’t cooling as is used to
  • There’s more dust near the air vents
  • A dirty filter surface
  • Burning smells near your HVAC system
