When buying an air filter for your HVAC system, you need to know what size you need. Buying a filter that fits inside the air filter compartment properly is essential. One of the most popular air filter sizes is 20x23x1, suitable for standard homes and businesses. They can trap most air particles in any space, such as dust mites, pollen, and mold, among other things.
But before you buy a 20x23x1 filter, you need to choose the right manufacturer. Many air filter manufacturers make filters of this size, but only three on the market have gained wide popularity for their construction and durability. These are:
- Filter King
- FilterBuy
- Nordic Pure
Each manufacturer has something unique to offer.

Filter King
20x23x1 Filter King air filters are considered one of the best on the market — and for good reason. The best part is that you can choose the filter quality as well. The higher the quality, the higher the MERV rating — and the more you would have to pay.
But their standard models work excellently, too, and provide supreme protection against smoke, pet dander, bacteria, dust mites, pollen, and other airborne particles. The line-up starts from the standard air filter with a MERV rating of 8 and goes up to MERV 13, which is popular among homeowners.
What Makes Them Different
Filter King manufactures 20x23x1 pleated air filters instead of fiberglass filters, making them about 20 times more effective. Speaking of the frames, they come with horizontal grid supports and are made from heat-resistant paperboard. Due to their sturdy construction, they can handle up to 200° F and sport excellent resistance against moisture.
FilterBuy
FilterBuy is another prominent air filter manufacturer with scores of customers in the United States. The 20x23x1 filter they’ve designed comes in three MERV ratings — 8, 11, and 13. All three are good options for home and office use, provided they are compatible with your HVAC system specifications.
You can customize your order by choosing the quantity of each air filter and buying exactly what you need.
What Makes Them Different
FilterBuy’s 20x23x1 air filter is known for its durability. They can last about three times longer than fiberglass filters and are made to last up to 90 days. With their filter, you can manage your home’s indoor air quality and protect your family from harmful particles that could trigger allergies or asthma.
The frames of the filter are made of a beverage board, enabling it to withstand temperature levels up to 200° F and humidity.
Nordic Pure
Next, we have Nordic Pure. Along with Filter King and FilterBuy, Nordic Pure is among the best 20x23x1 air filter manufacturers. Their filter is perfect for both residential and commercial uses. They are known for their sturdy construction, durability, and exceptional filtration capabilities, making them one of the best on the market.
What Makes Them Different
The pleated air filter by Normic Pure can handle a range of particles, including bacteria, dust, pet dander, smoke particles, allergens, and viruses. With a heavy-duty, moisture-resistant frame, you can expect this air filter to stand the test of time. Their attention to detail makes their product popular. Yet, it falls short of what the air filters Filter King has to offer. Although, in the end, the best air filter for your needs depends on your needs and budget.
These three manufacturers are considered the best on the market. If you are unsure about which one to choose, speak to a professional for expert guidance.
How Often Should You Change an Air Filter?
Regardless of which air filter company you choose to buy from, you must change the air filter regularly to keep the air healthy and safe. The interval between each change depends on several factors. If you have someone in your home who suffers from asthma or allergies, then it’s best to change the filters after every six weeks.
On the other hand, if your pets shed, then it’s ideal to replace your filter every two months. Other than that, changing the filter every two to three months is essential to keep your home or office safe and healthy.
