  • 1000 MPR has a rating of MERV 11
  • The higher the MPR, the more microparticles--such as pollen, pet dander, smoke,...

The famous Filtrete Allergen Defense is an excellent option for a furnace filter since it effectively reduces dust, allergies, and other airborne particles. The MERV 11 rating of this furnace filter indicates that it removes more than 90% of particles between 1 and 3 microns in size. (A MERV 11 filter would be classified as “Superior Residential” under ASHRAE standards.) It filters smoke and smog and is greatest at capturing dust, pollen, and pet dander.

The filter is simple to install, ideal for use in a central or wall unit, and electrostatic, meaning the fibers inside the filter cartridge have been “charged” to attract and hold onto dust and other particles. It should be changed, like many 1-inch furnace filters, every one to three months. You may monitor this with the Filtrete Smart app. Simply scan the package’s barcode, choose how frequently you want the filter to be replaced, and you’ll get a notification when that time comes.

Filters in your furnace prevent material from entering the heating, ventilation, and air conditioning (HVAC) system, which could cause damaged components, soiled ductwork, and poor indoor air quality. Even if it’s only a cheap, disposable furnace filter like the Filtrete Basic Dust and Lint Air Filter, you should always have one installed in your home.

This furnace filter collects particles between 3 and 10 microns in size and is designed to be swiftly installed and readily disposed of after its 90-day usage. The Filtrete Basic Dust and Lint Air Filter is ideal for minimizing common household allergens including dust, lint, and dust mite detritus, as the name suggests. Its MPR 300 rating is not as high as that of more sophisticated furnace filters, therefore it won’t be able to trap as many microparticles. However, compared to the most inexpensive furnace filters, this one is a definite upgrade thanks to its MERV 5 rating.


  • Affordable
  • Quick installation


  • Limited MPR 300 rating

Buying Guide: What to Things When Choose a Furnace Filter 

a) Air Filter Type

Both temporary and permanent furnace filters are readily available in a wide variety of configurations. The normal lifespan of a disposable filter is 30–90 days, while there are longer-lasting variants available (up to 6–12 months). Most inexpensive disposable furnace filters are constructed of fiberglass and can only filter out bigger dust and dirt particles. Synthetic filter media, which has a higher capacity to catch air pollutants, is another option.

When properly cared for, permanent furnace filters can serve you for many years. Filters for heating systems of this type require extensive washing and rinsing to remove debris and pollutants.

It is possible to install an electrostatic filter on either a disposable or a permanent furnace filter. To capture dust and other particles, these filters use material that is permanently charged (often cotton or paper).

b) MERV Rating

The ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) created the Minimum Efficiency Reporting Value (MERV) rating system so that consumers could easily evaluate the filtration efficiency of different brands of air cleaners.

The minimum efficiency reporting value (MERV) for furnace filters is 1. Filters with a MERV rating of 1 are the least efficient, filtering out particles as large as 10 microns, while filters with a MERV rating of 16 can collect particles as fine as 0.30 to 1 micron.

A filter with a MERV value of 1 to 4 could be enough for most standard household needs. However, a MERV 5 to MERV 8 filter is the superior option for most houses. It’s recommended that you get a filter with a MERV 9 rating or above if you want to improve air quality and cut down on allergies.

c) Filter Performance Rating

The Home Depot has created its own ranking system called the Filter Performance Rating (FPR). It takes into account the filter’s lifetime, its capacity to trap large and tiny particles separately, and any weight gain due to particle capture. To help customers select the best furnace filter, it ranks filters from decent to better to best to premium and gives each a score out of 10.

d) Filter Material

Filter media for heating appliances can be made from a variety of materials, such as fiberglass, cotton, polyester, or synthetic fibers. It’s common knowledge that fiberglass furnace filters are the most budget-friendly disposable option. While their low air resistance makes them easier for HVAC systems, their inability to trap smaller particles means that only larger debris is removed. Pleated furnace filters, whether they’re comprised of cotton paper or synthetic fibers, have the advantage of a higher filtration rate but may reduce airflow. The filters used in heating systems can be removed and washed if they are made of cotton or synthetic fibers.


It’s only normal to have questions regarding the best furnace filter for your home, given the wide selection of filters available, each of which claims to do an excellent job of filtering the air and capturing dust and other airborne particles.

i) What is the best MERV rating for furnace filters?

While the highest MERV rating is 20, the highest quality filters are typically only installed in hospitals and universities. In the case of home heating systems, a rating of 12 is optimal.

ii) Do higher MERV ratings decrease airflow?

As the MERV rating increases, airflow restriction typically follows. However, the limitations have little to no effect when applied in a domestic context.

iii) Is a thicker furnace filter better than a thinner one?

The opposite is not always true. Denser, thicker filters are better at trapping dust and other particles, but they may make your heating system work more to draw in air. Be sure to only use filters of the type and thickness suggested by the furnace’s maker.

iv) What is the best type of furnace filter for viruses?

Most home furnaces cannot pull air through a dense HEPA filter, but according to a CNN report, HEPA filters with MERV ratings of 17 to 20 are optimal for preventing the transmission of viruses.

v) How often should you change your furnace filter?

Filters for heating systems often come in packs of four to six since they need to be swapped out every two to three months. Some alternatives, however, can go nine to twelve months without being replaced.


The Filtrete Allergen Defense is the best furnace filter available, in our opinion. The MERV 11 rating indicates that this air filter captures particles more effectively than others. Being an electrostatically charged filter, it draws in and traps particles of dust and the like. However, if you’re merely looking to extend the life of your HVAC system by catching big particles, the Rheem Indoor Air Filter is a great cost-effective option. These filters typically come in packs of three or more and have a MERV 8 rating.
