Best 20x20x1 air filter?

To properly maintain your home's heating and cooling (HVAC) system, you should replace the air filter regularly. Air filters are designed to improve air quality by reducing a variety of particulates found in the air you breathe every day. But the options for air filters of 20x20x1 are enough. The well-known Filtrete brand, manufactured by 3M Corporation, has earned a reputation in the filtration industry.

This Micro Allergen Defense model is more than just a common air conditioning filter. With an MPR rating of 1100 (equivalent to a MERV 11 rating), this provides a high degree of filtration to remove impurities from the air. Since MERV ratings range from 1 to 16, this air filter is an excellent choice if you consider having desirable air quality. This air filter uses 3-in-1 technology that sucks in unwanted air particles, traps them, and then provides you with fresh air in return.

With this technology, you are less likely to experience poor indoor air quality and higher energy costs. Available in over a dozen sizes, the Filtrete AC oven air filter comes as our best overall oven replacement filter. Its high-efficiency MERV-12 rating makes it a great choice for homeowners who want to trap as much debris as possible in the air. You may also be exposed to viruses and bacteria, so improving air is better for your overall health.

K%26N has made a name for itself in automotive air filters and brings this expertise to home HVAC systems with this permanent furnace filter. Compared to cheaper basic filters available, medium-efficiency MERV filters like the Nordic Pure MERV 12 can greatly reduce airborne dust, mold spores, pollen and even smoke, and doing so can help ease respiratory ailments, according to an NIH review. Essentially, cheap air filters without a MERV rating can be so porous that particles that can damage your HVAC equipment can pass through the filter. Filtrete uses exclusive 3-in-1 technology to trap lint, dust, pet dander, soot, pollen and mold spores, while allowing fresh air to flow through the filter.

A MERV 11 20x20x1 pleated air filter will achieve superior performance by using electrostatic properties to filter more and smaller particles from the air your family breathes in your home. You can buy 20x20x1 air filters in bulk (a box of six) and save a considerable amount of what you would pay at ACE Hardware or Lowes for a single filter. While the home depot uses FPR, the industry standard is to use the Minimum Efficiency Report Value (MERV) air filter rating system. Coarser filters are denser and block more dust and particles, but they can also make the oven work harder to suck in air.

Fiberglass, polyester, washable, pleated and electrostatic filters offer different air filtration capabilities. This static creates a load that essentially absorbs all unwanted air parts, leaving you with a higher quality of air to breathe every day. The air is charged with particles, sent through the filter only once and the results are measured. Created with a washable and reusable material, this is a fantastic option for you if buying air filters often isn't appealing.

This reuse factor also adds an environmentally friendly element, as you don't have to constantly buy and dispose of new air filters.
