Frequently Asked Questions (FAQ)

1. How often should I replace a 16x25x4 Honeywell furnace filter?

Replace every 6 to 12 months, depending on usage, indoor air quality, and whether you have pets, allergies, or high HVAC usage. Homes with pets or allergies may benefit from replacing it every 6 months.

2. What’s the difference between MERV 11 and MERV 13 in Honeywell filters?

  • MERV 11: Great for dust, pollen, and pet dander

  • MERV 13: Captures finer particles like bacteria, smoke, and some viruses
    Both are excellent, but choose MERV 13 if health and air purity are top priorities.

3. Is 16x25x4 the actual size of the filter?

Not exactly. The nominal size is 16x25x4, but the actual size may be slightly smaller (e.g., 15.75" x 24.75" x 4.38"). Always check the manufacturer’s specs or your old filter’s label before ordering.

4. Will a 4-inch filter like this fit my HVAC system?

Check your system’s filter slot depth. If it’s designed for 4-inch filters, the Honeywell 16x25x4 will fit perfectly. If you currently use a 1-inch filter, you’ll need to confirm compatibility or consult your HVAC technician.

5. Do Honeywell furnace filters lower energy bills?

Yes. Higher-quality filters like the Honeywell 16x25x4 improve airflow and reduce system strain. Based on customer feedback and field data, many users report lower energy usage and fewer HVAC service calls after upgrading.
