✅ Frequently Asked Questions

❓ What does a 24x25x4 BDP HVAC furnace air filter do?

 The 24x25x4 BDP filter traps airborne particles like dust, pollen, pet dander, and mold spores before they enter your HVAC system. It protects your equipment from damage and helps maintain healthy indoor air quality.

❓ How often should I replace my 24x25x4 BDP furnace air filter?

 For most homes, replace it every 60–90 days. If you have pets, allergies, or live in a high-dust area, change it more frequently—every 30–60 days is ideal.

❓ What happens if I don’t replace my HVAC filter on time?

 A clogged or old filter can restrict airflow, causing your system to work harder. This leads to higher energy bills, poor indoor air quality, and can even damage components like the blower motor or heat exchanger.

❓ How do I know if the 24x25x4 filter is the right size for my BDP furnace?

 Check your furnace manual or look at your current filter’s frame. The size should be printed on the side. The “24x25x4” refers to the filter’s dimensions in inches (length x width x depth).

❓ Are there different quality levels for 24x25x4 BDP filters?

 Yes. Filters come in different MERV ratings. For most homes, a MERV 8 to MERV 13 filter is best. Higher MERV ratings capture finer particles but may restrict airflow if not compatible with your system.
