Frequently Asked Questions (FAQs)
Can I use a 16x25x4 filter instead of 16x25x5?
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.
What is the actual size of a 16x25x5 air 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.
Will a 16x25x5 MERV 13 filter restrict airflow in compact systems?
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.
Why are 16x25x5 filters more expensive than 1-inch filters?
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.
Does a narrower 16x25x5 filter work as well as 20x25x5?
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).
Are 16x25x5 filters harder to install than wider 5-inch filters?
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.
Do all 16x25x5 filters fit Honeywell and Aprilaire systems?
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.
Will a 16x25x5 filter improve my indoor air quality significantly?
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.
