Choosing the right 1 inch furnace filters for your system can be a daunting task. Our 1 inch air filters are not only used for furnace filters despite the common term, but are also a great choice for air conditioners and combination HVAC systems. Made in the USA, our filters provide high quality pleated media to capture airborne particulate matter before it enters your system.
Just be sure to select the correct size for your heating and cooling systems. A filter that is too small allows gaps for contaminants to enter into your system and home. You can find the correct size for you by checking your system manual, viewing the sizing on your old filter, measuring your old filter, or measuring your cabinet space. SpiroPure makes it easy to find the right size for your filtration system by offering both standard sizes and custom sizes of filters so you can ensure the perfect fit.
What do we mean by both nominal standard sizes and custom sizes are available? Nominal sizes are filters that are labeled by cabinet size rather than actual filter size. The actual 1 inch air filter will be smaller than the listed nominal size. For example, a 20x20x1 filter is most likely an actual size of 19.5x19.5x0.75. Custom size filters are cut to order to the requested actual size. However, even a custom size 1 in filter is actually cut to 0.75”, which is the industry standard thickness for 1 in air filter replacements. The easiest way to find our the size of furnace filter you require is to check the printed dimensions on your current air filter.
In addition to running effectively, your system may last longer with less failures with regular changing of furnace filters. A dirty air filter hinders air flow, causing strain. Our air filters are not only premium quality, but are also available in bulk packs with regular email reminders, ensuring you are ready to go when it is time for replacement.
In general, 1 inch furnace filter replacement is every 30-90 days, but this number can increase depending on lifestyle factors like pets, allergies, smoking, and more. Houses with pets, for example, may need to replace filters more often to maintain air flow A MERV 13 filter will also need more frequent replacement than a MERV 8 rated filter.
