When To Choose Custom Size HVAC And Air Filters

Custom Air FiltersWhile there are many standard and commonly used air filter sizes, the HVAC industry as a whole has not standardized air filter sizing. Most of the time, air filter sizes are determined by the manufacturer of your HVAC unit, based off the finished size of the unit itself, instead of the standard size air filters available. This can be quite an inconvenience for many homeowners. Some will recommend your focus should be on the type of air filter you use. While this is important, when choosing custom size air filters, your main concern should be determining the exact size you need. The type of filter you use is irrelevant if it does not fit properly. If you've measured your air filter housing slot and are unable to find a standard sized air filter within 5/8th-inch smaller than the housing slot, then your unit requires a custom sized air filter.

Custom air filter sizes are not stocked on shelves or found at local stores. There are tens of thousands of possible size combinations for filters so there is no way to keep each size in stock. However, you can get the exact size you need by building a custom air filter. US Home Filter keeps a vast array of standard sizes, including many uncommon hard-to-find sizes, in stock and can make any custom size air filter that you may need!

The Purpose of Air Filters: Why Size Matters

An air filter's main purpose is to keep the air we breathe as clean as possible. They also prevent atmospheric dust and other airborne particles from building up on heating and cooling system's fan motor, coil and drip pans. If your air filter isn't clean, your furnace or AC system cannot operate properly, leading to costly repairs and replacements. It is imperative to ensure your air filter fits your unit properly so the air can move THROUGH the filter, not around it. If you have the wrong sized air filter in your unit, dust, allergens, and pollutants will not be filtered from your indoor air, as the air is bypassing the filter, entering and returning into the ventilation.

This is where custom air filters can be extremely beneficial. Once you have determined the filter size you need, it is important to change your custom air filters on a regular basis. By doing so, you will have a constant flow of clean air coming into your home, avoiding respiratory difficulties, allergies, and illness.

Custom Air Filters Reduce Indoor Air Pollution

According to the EPA, indoor air pollution is among the top five environmental health risks. Making sure your air filter fits properly within your system and regularly cleaned is imperative to keep your furnace or AC system operating properly and preventing indoor air quality. This is where custom sized air filters are essential. As we stated before, the air should move through the filter, not around it, so those indoor air pollutants are caught in the filter.

After you've figured out the exact dimensions you need for your custom air filters, then you can choose the type of filter you want/need. This selection will depend on your budget as well as the level of filtration you want.
