Why Buy Air Filters From Filter King?

In comparison to fiberglass filters, 17.25x17.25x1 pleated air filters are at least 20 times more effective. All Filter King air filters are made in the US.

Filters frames are made out of heat resistant paperboard with horizontal grid supports. Able to withstand temperatures of up to 200° F and resistant to moisture, the paperboard frames do not support microbial growth and outperforms traditional cardboard frames.

Chemical free, electrostatically charged synthetic polyester media is pleated, maximizing the surface area, to capture a high number of airborne particles as small as 0.3 microns with low air flow resistance. To increase durability, the media is supported with a corrosion resistant steel wire.

How Often to Change Your 17.25x17.25x1 Air Filter?

Filter King AC & furnace filters aren’t the typical fiberglass filters that need to be replaced every 30 days. Our filters can typically be used for 3 to 5 months before requiring to be changed. Naturally, a variety of things influence filter lifespan.

Some of the factors that influence your filter’s life include outdoor air quality, whether pets are in the home, and how well your HVAC system is maintained.

Your air filter becomes clogged over time by trapped particles, preventing airflow. The efficiency of the HVAC filter declines. Your system must work harder to heat and cool your home. The extra strain on the HVAC system causes higher energy bills. Regular home air filter replacements can prevent expensive system repairs or replacements down the road.

You should change your filter more frequently if you notice:

Household dust build-up
The air isn’t cooling as is used to
There’s more dust near the air vents
A dirty filter surface
Higher energy bills
Burning smells near your HVAC system.

Why Picking the Right Filter Size Matters

Too Small? The air might sneak around the edges of the filter, causing noise and letting dust and other tiny bits float around your home.

Too Big? The filter will not fit into the vent/return.

Getting it Wrong? It could end up costing you more since sending back wrong-sized filters isn't cheap.

How to Avoid Mistakes

Know the Difference: Nominal vs. Actual Size

Nominal Size is the rounded number you see in ads or on boxes.
Actual Size is the real deal – the exact size of the filter.

Think of it like this: a filter might say 20x20x1 inches – that's the nominal size. But in reality (actual size), it might be a bit smaller - 19.5x19.5x0.75.

Both these sizes should be on your filter or heating/cooling system. Can't find them? Best to grab a tape measure and check. If you don’t have an existing filter to measure, simply measure your return vent.

Finding Your Filter on Our Site

Go to our homepage at filterking.com
Pick the type of filter you need, like one for a furnace.
Choose the thickness (it's usually a number from 1 to 6 inches).
Next, pick the length and width (like 20x20 from our example).

Can't find your size? No worries, we can make one just for you. Just ask us!

Can't Find Your Size? Use the Model Number

Sometimes filters have a model number (like "Honeywell FC40R1094"). Just type this number into our search bar.

Checking Your Choice

Did you find a filter? Great! Just double-check that the actual size listed on our site matches your needs. If it's super close, you're good to go.
