Sometimes you may find HVAC systems that require non-standard sized air filters, which is the main reason why there are so many options for customizing air filters. Whether you are looking to get custom furnace filters online or from local stores, that is something you should consider.
Where to Order Custom Size Air Filters
Most air filter manufacturers offer customized filters. When you are buying air filters, you should find out if the manufacturer has filters that would match your HVAC system. Be cautious and ask about their return policy just in case they don’t fit.
Most companies offer premium custom air filters and provide safe, efficient, and cost-effective filters for your furnace and air conditioning units. Custom size filters are generally built to your exact specification to tolerances of + or – 1/8″. Their lead time may take longer than the standard size filters, but they are usually shipped within two weeks.
Choose The Right Size
If you order your custom size air filters online, you will first need to choose your dimensions (length, width, depth). When measuring your filter, check whether it is square; if not, measure the shortest side first, then the longer side, and lastly, the depth. It would be best to round the measurements up to the nearest whole number, as the filter will generally be smaller than the nominal size.
Choose the Right MERV Rating
After choosing the size of your air filters, you need to select your filter material. Most providers offer MERV-rated filter media of 8, 11, and 13. MERV 11 is best for pet owners, while MERV 13 is ideal for those with allergies or asthma.
- MERV 8 – blocks mold spores, dust mites, lint, household dust, and pollen
- MERV 11 – blocks odors, pet dander, smoke, smog, dust mites, mold spores, lint, household dust, and pollen
- MERV 13 – blocks bacteria, pet dander, virus carriers, smog, mold spores, lint, household dust, pollen, smog, microscopic allergens, and coronavirus
Why are Custom Air Filters Important?
According to the Environmental Protection Agency (EPA), indoor air pollution is among the top five environmental health risks. Air filters must fit properly within your HVAC system and be regularly cleaned to ensure that your AC operates efficiently and you have good indoor air quality.
The air must move through the filter and not around it; otherwise, the system will not filter dust, allergens, and pollutants from the air. But once you determine the size of the filter you need, it is highly beneficial to clean or replace it regularly. By doing so, you will ensure a constant flow of clean air coming into your home while avoiding illness, allergies, and respiratory difficulties.
There are several air filter sizes, and most sellers can help you get the correct filter. No matter what HVAC system you have, it needs the proper filter to run at its maximum efficiency and keep your home safe and the air you breathe clean.
If your air filter is not the correct size, your furnace may not operate properly, leading to costly repairs or even replacement. It is imperative to have a properly fitting air filter for your HVAC system, as it will increase your system’s performance and longevity while decreasing energy bills.
