When was the last time you replaced your furnace or air filter?
Before switching the "on" button, your home's furnace filter should be inspected and replaced. Your furnace will run more efficiently and your indoor air can be improved by replacing your furnace filter on a regular basis. The cost of replacing your furnace filter on a regular basis vs the damage that can be caused by a dirty furnace filter makes it a simple choice.
What is the difference between Furnace Filters and Air Conditioner Filters?
There is no difference between furnace filters and air conditioner filters. If a filter is listed as a furnace filter it can also be used in a air conditioning system. More often than not they are referred to as furnace filters. Other terms you may come across are HVAC filters, home air filters, pleated furnace filters, basic fiberglass furnace filters and more. Your main concern should be the filter size and how well you would like to improve indoor air quality (IAQ).
Can't find your filter size anywhere?
Are you having a tough time finding your filter size? We can help by making you custom furnace filters to your exact size. Custom furnace filters provide the filtration and protection you need. The primary purpose of furnace filters are to protect your system, so with out a properly fit air filter the protection won't be sufficient. Custom furnace filters and AC filters will help protect your system and improve your indoor air quality.
Filter Sizing
Where is my filter located?
Your filter can be located anywhere between the furnace and the where warm or cool air enters the room. Common locations include inside the ductwork, behind vents or in the air handler itself.
What size filter do I need?
Most furnace filters have two sets of dimensions; nominal and actual. If you measure your filter and it's actually 15 1/2" x 24 3/4" x 3/4", you would round up and search based on the nominal dimensions of 16" x 25" x 1". If the nominal size isn't printed on your old filter just measure your filter width, length and thickness. Round up and you'll get the nominal size. We always recommend measuring your filter just to be sure.
Custom size filters
When ordering custom filters submit the exact size down to 1/8" you would like us to make your filters. Please don't submit the nominal size (rounded size) of the filter, submit the actual exact size.
