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: 15.38x25.5x5.25
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!

The 16x25x5 furnace filter is a premium filter size built for compact whole-house systems. This air filter is designed for specialized media cabinets, combining an extended lifespan with powerful airflow solutions. Its 5-inch thickness provides greater surface area compared to 1-inch air filters. This ultimately means fewer replacements for improved indoor air quality, or IAQ.
This article explains system compatibility, 5-inch performance in compact size benefits, MERV options, replacement timing, and selection guidance. In this guide, discover which air filters work for your household, whether your goal is to trap as many particles and allergens as possible or if you want to reduce dander from pets and odors from cooking.
Common brands such as Honeywell, Carrier, Trane, Lennox, Bryant, Goodman, and Aprilaire produce 16x25x5 air filters. These filters are common in systems that are designed for whole-home filtration (with smaller footprints). Typical compatible models include:
In most instances, these cabinets are installed between the air handler (or furnace) and return duct. Open the cabinet door to check existing labels printed on existing air filters that are currently in your media housing. You can also reference your HVAC system's official manual or guide to determine which filter size is right for you. The actual measured size of a 16x25x5 air filter is 15.5 x 24.5 x 4.75".
Even though 5-inch 16x25x5 air filters are a bit more compact than 20-inch solutions, their 5-inch pleated design provides the same advantages for those seeking premium air quality improvements.
Pleated media within the 16x25x5 air filters provide between 35 and 40 square feet of filtration surface. This is approximately 4 to 5 times more than traditional, standard, 1-inch filters. With larger surface area, it's possible to trap more allergens and particles while protecting and preserving airflow. In many cases, replacing a 16x25x5 air filter is only necessary once every 6 to 12 months.
With a pleated surface, these 16x25x5 air filters capture a greater volume of dust, dander, and airborne particles. Investing in these filters allows you to change your filters less often while enjoying consistently clean air.
Even with higher MERV ratings, this 5-inch depth filter is capable of maintaining its low static pressure. This design is ideal for blower performance while protecting your system's overall efficiency.
For homes with smaller HVAC media cabinets, the 16x25x5 air filter provides performance with a narrower carbon footprint. These filters provide the same benefits of a larger 5-inch pleated filter while fitting into compact media cabinets and systems without a hassle.
Filter King offers pleated air filters in various replacement sizes and with differing MERV ratings. Each is suited for different household needs.
With expanded surface area, 5-inch filters handle higher MERV levels without a hassle. Air is capable of spreading evenly through the pleats, which prevents airflow restriction. This makes 5-inch filters ideal for high-efficiency filtration demands without reducing overall performance.
16x25x5 air filters are designed for smaller, more compact homes and HVAC systems. These filters are also optimal for whole-house air cleaning. Common uses include:
A notable benefit of 16x25x5 air filters is its extended replacement cycle, requiring fewer replacements throughout each year. Many homeowners only need to change these filters every 6 to 12 months, depending on environmental factors and lifestyle demands.

As a customer of Filter King, selecting a filter that's designed for smoke, allergens, and airborne particles is a decision you should not take lightly. When selecting an air filter for your home, there are a few steps to follow for the best results:
Compatibility: Verifying system compatibility is crucial as a homeowner when investing in new air filters. Check your cabinet's size label and existing filter labels to determine which size (and depth) is ideal for your current HVAC system or setup. Confirm that 16x25x5 is the right dimension for your next filter before placing an order.
Household needs: MERV 8 is ideal for basic protection, whereas MERV 11 and MERV 13 are designed for excessive allergies and even those who struggle with asthma. For odor control, consider MERV 8 Carbon filters (especially in homes with plenty of smoke and smoke from cooking).
Airflow: The 5-inch pleated design supports even higher MERV ratings in compact systems without interfering with airflow.
Budget considerations: Replacing a 16x25x5 filter will likely be necessary once every 6 to 12 months, depending on environmental and runtime factors involving your HVAC system. Consider investing in multi-packs by purchasing your filters in bulk or using Filter King's subscription solution for the best value.

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.
