Whether you’re getting ready for summer air conditioning or heat in the winter, your filter affects the air quality in your home. Before you grab the first inexpensive air filter at the store, here’s what you need to know.

Best Air Filtration For Your Home

Dirty AC filters not only reduce air quality but also affects your energy bills. Clogged filters reduce airflow, making your HVAC system work harder. Low airflow means your AC is running longer and more often, causing a spike in your utility bills.

The best HVAC air filters for the home fit your system perfectly. You don’t want gaps around the edges or a filter that’s bent to fit inside. Thicker filters are better equipped to prevent dust, pollen, and other allergens from getting into the air you breathe at home.

Know This Before Buying

You need to know a few things before buying air filters for your home’s ac. It will ensure you get the best home air filter that will also last through the season.

Filter Type: Not All Filters Are Created Equal

There are several types of home HVAC filters, and not all are created equal. Materials vary, along with other factors, such as high-efficiency. What works great for your neighbor may not be the best air filter for your home furnace.

Pleated vs. Fiberglass Filters

Fiberglass air filters are easy to find and are usually affordably priced. The flat design is adequate at filtering out particles, and you throw it away when it’s time for a replacement. Initially, you will save money. The filters are cheaper than some other types. However, you will have to replace it more often. Some of the best ac filters are pleated. Pleated or folder air filters are less porous than flat ones. You will pay a little more, but these filters also trap more airborne allergens. You still want to change the filter every six months, but it will work longer than a fiberglass one.

Disposable vs. Washable Air Filters

Eco-conscious consumers may want to opt for washable air filters. You are reducing your carbon footprint, but there is a downside. Reusable filters aren’t designed to trap small particles. You’ll still breathe in allergens in your home.

The best house air filters are disposable. While washable ones will filter out dust, disposable ones also trap smoke, bacteria, and pet dander. You’ll breathe easier at home with a quality disposable air filter.

HEPA-Type Air Filters

Chances are you’re not using true HEPA filters. These medical and industrial-grade air filters are expensive and aren’t always designed for home use. You can boost indoor air quality with a true HEPA air purifier. These filters are priced higher but are worth it to prevent allergies and bacterial viruses.

HEPA type air filters do not trap 99.97% of airborne particles, but they come close. Only true ones meet the exact standard. Some of the newer and high-priced HEPA-type filters can trap up to 97% of dust, smoke, and allergen particles. However, before you buy one, carefully read the manufacturer’s specifications to see if it is a true HEPA air filter.

MERV Rating: What Are You Filtering Out?

The minimum efficiency reporting value (MERV) refers to the air filter efficiency. The higher the MERV rating, the better the filter is at trapping large and small particles. The MERV rating also denotes the filter’s use. Air filters with lower ratings are typically found in commercial and residential buildings, while higher rated ones are used in hospitals and industry settings.

MERV Rating 1-6: Pollen, Dust Mites, Carpet Fibers, etc.

Air filters with MERV ratings ranging from 1-6 trap particles with a 10.0-micron size and larger. They are often used as a pre-filter in commercial buildings to provide staff with added protection. You can also find these air filters in window ac units and residential furnaces.

MERV Rating 8-13: Fumes, Smoke, Mold, Dust Mites, Smog, etc.

Depending on the type of industry, these filters are used in both commercial and residential structures. They can filter out particles with sizes from 3.0-10.0 microns. Dust from sand and cement work is trapped in the filters, along with dust, dust mites, mold spores, and carpet fibers.

MERV Rating 14-20: Bacteria, Viruses, Odors, etc.

These are the best air filters, very few microscopic particles get through. Hospitals, operating and smoking rooms all use this type of filter. It is able to trap particles as small as 0.30 microns. They will also filter out carcinogenic and radioactive materials. These are industry quality air filters and are rarely used in the home.


The air you breathe does affect your health. It’s why you want the best air filter for your home.. You’ll find the same pollutants indoors as you do outside. Every time you open a door or window, you’re letting airborne particles in.

The best air filter for your home ac eliminates the particles that irritate existing breathing conditions like pet dander, dust, mold, tobacco smoke, and other allergens.


How often you change your home’s air filter matters. Filters do get clogged, slowing down airflow and letting allergens pass through. Some people only change their air filters twice a year, typically in the summer and winter. However, it might not be often enough.

30, 60, or 90 Days Replacement Duration

There are a few factors to consider when you’re deciding how often to change your air filter. If you don’t have pets or allergies, once or twice a year is fine. Otherwise, you want to plan on replacing the air filter more frequently.

  • 90 Days: You should switch out your air filter every 90 days if you don’t have pets, but more than one person lives in the home.
  • 60 Days: People with one pet and/or allergies will want to replace their air filters every two months.
  • 30 Days: Anyone with multiple pets should change their air filter once a month. It also applies if someone in the home suffers from a breathing condition.
