Check the label on your current filter or use a tape measure to determine the length, width, and thickness. Just make sure you know the difference between nominal and actual size.
Nominal Size: 16x25x5
Actual Size: 15.88x24.88x4.38
Nominal size is what you normally see printed on the label. This is usually a rounded size which is often not the true size of your filter.
Actual size is the true size of the air filter, usually written in smaller font below the nominal size.
Measure your current air filter or the length, width, and depth of the opening slot to get the actual size. Round it up to the nearest whole inch to get the nominal size.
Installing 16x25x5 furnace filter or HVAC air filter is easy. Just make sure to align the arrow printed on the side with the airflow direction!
Remove the air filter from the package
Locate the arrow and point it in the direction of the fan
Slide the filter in to the slot of the central unit
For return grills, insert the filter into the grill, pointing the arrow inwards

No, a 16x25x4 filter will not fit properly if your media cabinet or HVAC system is designed for a 5-inch filter. A smaller filter will leave gaps, making your filter much less efficient. Always verify the proper size of the filter you require before replacing an existing filter.
The actual size of a 16x25x5 filter is 15.5x24.5x4.75 inches. These measurements are designed for a proper fit in media filters that require a 16x25x5 filter.
No, the 5-inch pleated depth provides adequate surface area to maintain airflow, even with higher MERV ratings being considered. Compact systems can handle MERV 11 and MERV 13 filters without causing unnecessary strain on your system.
16x25x5 filters are more expensive than 1-inch filters as they provide an extended surface area with the use of premium materials. Reinforced paperboard frames are also included. In addition, 5-inch pleated filters provide between four and five times more the filtration media. Additionally, replacing a 16x25x5 filter is often only required once every 6 to 12 months, depending on system runtime and household environmental factors.
Yes, both filter sizes perform similarly in terms of lifespan. Choosing a width that matches your HVAC cabinet's design is ideal for the best seal and for proper airflow (without causing strain on the system).
No. 16x25x5 air filters can be installed as any other air filter. Installation is straightforward and involves sliding out and replacing old filters with a new filter while ensuring the airflow arrow is pointed toward the furnace or motor blower. When a filter fits in its designed media cabinet, you should experience little to no resistance as you replace it.
No, not all 16x25x5 filters fit every whole-house air cleaner. Honeywell, Aprilaire, and Lennox cabinets may all vary slightly, which is why paying close attention to the descriptors on your frames matters. Take a bit of time to match your system's model number to ensure the correct fit when shopping for a new air filter product, even when doing so via Filter King.
Yes. A 16x25x5 filter captures more pollutants, dust, and allergens over time than thinner, 1-inch filters. Its deep-pleated design ensures consistent filtration, improving your IAQ, or Indoor Air Quality, in less time.
