As a homeowner, one of the simplest things you can do to keep clean air circulating through your home is to change the air filter. The filter traps dust particles, contaminants, and pollutants as the air passes through, purifying the air on the other side. <\/p>\n\n\n\n

In a perfect world, the most effective air filter you could buy for your HVAC system would capture up to 99.9% of particles but allow the air to pass through without straining your HVAC\u2019s blower or other moving parts. <\/p>\n\n\n\n

If you\u2019re wondering what the most effective type of air filter is, then read on. We discuss the importance of air conditioner filter replacements<\/a>, discuss the best air filter ratings, and compare popular products.<\/p>\n\n\n\n

\"What<\/figure>\n\n\n\n

Why Are Air Filters Important in Your HVAC System?<\/h2>\n\n\n\n

Construction and HVAC companies started using air filters in HVAC<\/strong><\/a> systems as early as the 1940s as a way to reduce dust and odors. The concept still stands today. Air filters play a central role in heating and cooling hygiene. <\/p>\n\n\n\n

A filter performs five valuable functions:<\/p>\n\n\n\n

    \n
  1. Improve indoor air quality<\/li>\n\n\n\n
  2. Enhance system efficiency<\/li>\n\n\n\n
  3. Prevent dust buildup in ducts<\/li>\n\n\n\n
  4. Protect HVAC components<\/li>\n\n\n\n
  5. Reduce energy consumption<\/li>\n<\/ol>\n\n\n\n

    These functions add up to a core HVAC component that keeps your air conditioner running smoothly with less dirt buildup, fewer repairs, and lower energy consumption. As a result, you save money in the long run.\u00a0<\/p>\n\n\n\n

    As an added feature, a filter allows you to breathe cleaner air, which is always a good thing. If you have allergies<\/a>, an air filter is an essential part of your heating and cooling system.<\/p>\n\n\n\n

    Minimum Efficiency Reporting Value: What Is MERV and Why Is It Important?<\/h2>\n\n\n\n

    When comparing hvac filters, you need a measuring stick to determine which products do the best job of removing small particles from the air.\u00a0<\/p>\n\n\n\n

    The measuring stick we\u2019re referring to is known as the MERV rating<\/strong><\/a>. <\/p>\n\n\n\n

    MERV = <\/strong>M<\/em><\/strong>inimum <\/em>E<\/em><\/strong>fficiency <\/em>R<\/em><\/strong>eporting <\/em>V<\/em><\/strong>alue<\/em><\/p>\n\n\n\n

    The rating range is 1 to 20, with 1 being the lowest efficiency and 20 being the highest. For instance, a MERV rating of 1 suggests that a filter captures less than 20 percent of tiny particles. On the other hand, a MERV rating of 20 means that a filter captures 99.9+ percent of tiny particles. <\/p>\n\n\n\n

    \"What<\/figure>\n\n\n\n

    Look at the table below to compare six different MERV ratings to get a better idea of how the rating system works (keep in mind HEPA filters stand for High-Efficiency Particulate Air and refer to the air filter efficiency):<\/p>\n\n\n\n

    What MERV Is Best in an Air Filter?<\/h2>\n\n\n\n

    The best MERV rating depends on what you\u2019re using it for.<\/p>\n\n\n\n

    Now that you have an understanding of how the MERV rating works, you need to learn the best application for each rating or group of ratings. While filters with low ratings may not capture tiny particles, they are still ideal in certain settings. Filters with the highest ratings may do a better job of catching tiny particles but may not be good for your home. <\/p>\n\n\n\n

    Let\u2019s take a closer look at different ratings to determine how best to use them. Note:<\/strong> We\u2019re comparing 20x2x1 air filters:<\/p>\n\n\n\n

    MERV Rating<\/strong><\/td>Best Uses<\/strong><\/td><\/tr>
    1-4<\/strong><\/td>Best for residential window air conditioners and basic HVAC systems, filtering larger particles like dust and pollen.<\/td><\/tr>
    5-8<\/strong><\/td>Ideal for residential and light commercial buildings, capturing common pollutants such as mold spores and pet dander.<\/td><\/tr>
    9-13<\/strong><\/td>Suitable for hospitals and superior residential filtration, effectively trapping lead dust and auto emissions.<\/td><\/tr>
    14-16<\/strong><\/td>Used in hospitals and cleanrooms, capturing bacteria and smoke particles for high air quality control.<\/td><\/tr>

    What Is the Best 20x20x1 Air Filter for Allergies?<\/h2>\n\n\n\n

    One of the most common air filter sizes in homes is 20x20x1 air filters<\/a>. The size and dimensions are designed for durability, longevity, and capacity. It can capture a healthy amount of particles over a long period. The dimension also influences the MERV rating. <\/p>\n\n\n\n
