Frequently Asked Questions
1. How often should I replace my 20x20x4 Honeywell HVAC filter?
Typically, every 3 to 6 months, depending on your indoor air quality, usage, and whether you have pets, allergies, or live in a high-dust area. Regular checks can help you adjust the schedule as needed.
2. What is the difference between MERV 11 and MERV 13 in Honeywell filters?
MERV 11 captures common household particles like dust, pollen, and pet dander.
MERV 13 offers enhanced filtration for finer particles, including smoke, bacteria, and virus-carrying aerosols—ideal for allergy-sensitive homes or improved health protection.
3. Will a 4-inch filter fit in my HVAC system?
