Best Air Filter for Your HVAC

How To Pick The Best Air Filter For Your HVAC

Each HVAC system relies on air filters as a key component. The better the quality of your air filter system in the HVAC unit, the superior will be the air quality that you're breathing. Selecting the appropriate air filter is critical because if you don't, your HVAC unit will circulate dust particles throughout your home, posing a health concern.

It's critical to conduct thorough research while looking for the correct air filter for your best HVAC system in USA. Friends and family recommendations, internet user evaluations, and expert HVAC contractor recommendations can all help you make the right decision. However, be sure the air filter you choose is compatible with your particular furnace or air conditioner since each make and model differs.

Though there are a few elements to keep in mind when selecting an air filter for your HVAC system, it is critical. There is no need for you to worry if you are buying an air filter for the first time or if HVAC terminology isn't your strong suit. US Home Filter has you covered with some simple suggestions to help you choose the best air filter in the USA for your system.

1. Determine Which Filters Are Appropriate For Your System

The very first step is to determine which air filters are compatible with your HVAC system. Your HVAC system's owner's handbook or manufacturer's guide will tell you what size and kind of filter to use to get the greatest results. It's critical to pick a suitable air filter since it will result in improved and healthier indoor air quality as well as increased energy efficiency.

If you've lost your owner's handbook or manufacturer's guide, you'll need to measure the size of your present air filter to figure out which filters will work. Accurately determine the size of the present air filter in your HVAC system. As a rule of thumb, a normal air conditioning unit or furnace filter measures 20 inches in length and 25 inches in height.

2. MERV Rating

Minimum Efficiency Reporting Value, or MERV, ratings are used in the HVAC sector to assess the efficacy of various air filters. The MERV rating system evaluates how successfully air filters catch and screen dust, dirt, and other airborne particles. The greater the MERV rating, the better the air filter's capacity to catch dust particles and provide better indoor air quality.

Air filters having higher MERV ratings are often more costly since they perform better. The additional expense, on the other hand, tends to balance out. If you choose a cheap air filter with a MERV rating on the lower side, you'll have to change it sooner since it won't filter harmful airborne particles very well.

Manufacturers of custom air filters will occasionally utilize their own grading systems instead of the MERV system. If you purchase from such a manufacturer, keep in mind that a higher numerical rating typically means better filtration.

3. Choose The Right Material For Your Filter

For varied filter types and filter materials, you have a few distinct alternatives. A fiberglass filter is a common and economical alternative. These air filters are typically an inch thick and, being a low-cost and thin choice, are less effective at capturing dirt particles in the air. If you go with a fiberglass air filter, you'll have to change it at least once a month.

Pleated filters are an improvement over fiberglass filters. Pleated filters are frequently marketed in 4-inch thick versions, making them extra sturdy and effective in preventing dusty particles from entering your house and lungs. Whilst the up-front cost of pleated filters is a bit on the higher side than fiberglass filters, premium-quality pleated filters could easily last up to a year.

Another alternative that you have got is using a washable air filter. Washable air filters, which are often constructed of polypropylene media, are by far the most expensive alternative, but they may last for years and have a minimal environmental effect. Whilst fiberglass and pleated filters are only good for one-time usage before being discarded; washable air filters may be reused with regular washing.

4. Know The Right Time To Replace Your Filter

It's just as vital to know when to toss out your old air filter and replace it with a new one as it is to pick the appropriate one. If you follow the guidelines above and pick the proper air filter for your HVAC unit but don't change it on time, the filter will simply stop working as it should. The following are some indicators that your present air filter is unclean or blocked and needs to be replaced:

  • Dirt or other airborne particles visible in the air: If debris, dirt, or other air pollutants can be seen in the air within your house, it's time to replace the air filter. If the hazardous particulates are visible, your air filter is probably unclean or clogged, and it can no further collect and filter them.
  • Your home isn't properly heated or cooled: Your air filter may require replacement if the air conditioning system or the furnace is having trouble cooling or heating your house to the correct temperature. A filthy or blocked filter can cause your HVAC unit to function harder than necessary, eventually causing it to fail.
  • High electricity bills: When your HVAC unit has to operate more to cool your house or dissipate heat, it requires a lot of energy. You'll notice particularly significant energy costs if your air filters are unclean or blocked. A new air filter helps your HVAC system to work properly while using the least amount of energy feasible.


These four pointers should help you choose the correct air filter for your HVAC unit. In addition to these suggestions, it's critical to thoroughly investigate each prospective air filter before deciding if it's the right match. Customer reviews and other resources might help you understand the benefits and drawbacks of the filter you're contemplating buying. Given how important it is to choose the correct filter to preserve your and your family's happiness and comfort, you should take some time to evaluate different filters and make the finest decision possible.
