Best Air Filter For Your Home AC

It’s easy to become overwhelmed by the alternatives while shopping for a new HVAC air filter to keep your home’s air pure. Filters for your forced-air system are available in an almost limitless variety of sizes, materials, and filtration levels. 

If you change your filters regularly, have your AC system tuned once or twice a year, and don’t have allergies, a simple, low-cost fibreglass filter should suffice. Other types of air filters, depending on your needs, may be more suitable for your home. So, which one is best for your home, and how frequently should you clean the HVAC air filter? 

You are aware of the significance of replacing your home’s air filter. You likely update your AC filter at least three times a year, or at least homeowners should. Your filter impacts the air quality in your home, whether you’re preparing for summer air conditioning or winter heat. Here is what you need to know before purchasing the first cheap air filter for home ac at the store.

Is It Important Which Air Filter You Use in Your Home?

The one hard and fast rule regarding replacing your air filter is to buy the correct size for your system. You should be able to find the dimensions on the side of your old filter, or you may measure the size of your HVAC’s air intake vent before heading to the store.

Once you’ve determined the size you’re searching for; it’s time to consider the various sorts of filters:

  1. Fiberglass: The most prevalent and cost-effective HVAC filters; however, they lack effective air quality defense.
  2. Pleated: Pleated cotton filter surfaces trap more particles than non-pleated surfaces and range in price from $20 to $60. Washable filters are constructed of a synthetic substance and can be washed once a month for up to a year. They do not typically filter out as much stuff as other models.
  3. High effectiveness: Remove Most mold, dust, pollen, and bacteria with high-efficiency particulate air (HEPA) filters. HEPA filters offer the maximum level of protection for your house, with a MERV rating of almost 16. Even the tiniest microns or airborne particles, including tobacco and pathogens, can be eliminated by them. The most likely beneficiaries of HEPA filters are those who suffer from allergies or other respiratory conditions. A contractor must modify these filters to fit your particular HVAC system.

How Do I Select the Best Air Filter for My Needs?

Replacing your home’s HVAC air filter is essential to system maintenance. You should replace your air filter every three months for optimal performance.

You might want to try a different type the next time you alter your filter. Here are two reasons why you might want to change your filter:

Changing the Type of Filter for Convenience

It would help if you considered using a polyester air filter instead of a standard fiberglass filter because they last longer before they wear out. A fiberglass filter, for example, may only last one month, whereas a polyester filter will easily last three months or more.

Some homeowners can get away with waiting six months before changing them, depending on where they live. As a result, filter changes can be done quickly twice a year, at the beginning and the close of the AC season.

Changing the furnace air filter

A furnace filter is essential to any home’s ventilation system, helping keep the air going through your home smelling fresh and clean. Furnace filters need periodic changing, or they become dirty and ineffective. You can swap out furnace filters easily in a process that usually only takes moments. The furnace filter replacement steps are straightforward to follow.

Changing Your Filter Type for Allergies or Asthma 

Those who suffer from allergies or asthma should know the MERV (minimum efficiency reporting values) rating on modern air filters. The performance varies between filters and is ascertained with a MERV rating.

MERV ratings range from 1 to 16, but most home air filters fall between 1 and 12. The rating system indicates the filter’s capacity to catch particles between 0.3 and 10 microns. Higher ratings mean that the filter captures a given type of particle more effectively. Lint, pollen, and dust, among other more critical common particles, are primarily filtered out by MERV-rated filters with ratings between 1-4 that many homes install. Regrettably, they do little to capture tiny micro particles. The most effective MERV filters for eradicating bacteria, cigarette smoke, and sneeze residue are those rated 13 to 16, despite carrying higher price tags. For those who suffer from allergies and asthma, these are the most excellent options for air filtration.

A Different Filter Type Can Help You Reduce Your Carbon Footprint

There is a third, less popular option for altering your filter type. You can also get a reusable or electrostatic filter to lessen your home’s environmental impact. These are filters that you clean once a month as opposed to discarding and replacing.

This filter type’s electrostatic cells are 97% effective at capturing particles between 0.1 and 10 microns in size. In contrast, the HEPA filter is approximately 99.97% effective in capturing micron-sized particles between 0.3 and 10 microns. If none of those above scenarios apply to you, a fiberglass filter that costs less can be a great option.

Duration of Replacement: 30, 60, or 90 Days

When determining how frequently to change your air filter, there are a few things to consider. Once or twice a year is fine if you don’t have allergies or pets. If not, you should prepare to change the air filter more frequently.

90 Days: If you don’t have pets but have multiple occupants in the house, you should replace your air filter every 90 days.

60 Days: People with one pet and allergies should change their air filters every two months.

30 Days: Pet owners with multiple animals should change their air filters every month. It also applies if there is a resident with a breathing disorder.


Some disposable air filters cost less than $5, and others cost more than $100. The price and quality of the air filter are both influenced by the type. The best HVAC air filters don’t have to be expensive, but you also don’t want to get the most affordable ones.
