Frequently Asked Questions
What does a 14x24x1 air filter do?
A 14x24x1 air filter helps trap airborne particles like dust, pollen, pet dander, and mold spores before they enter your HVAC system, improving your indoor air quality and protecting your system from buildup and wear.
How often should I replace my 14x24x1 air filter?
You should replace it every 90 days under normal conditions, but if you have pets, allergies, or heavy HVAC use, it’s best to change it every 30 to 60 days to maintain optimal performance.
What’s the difference between MERV 8, 11, and 13?
MERV 8 provides basic protection against larger particles like dust and lint. MERV 11 offers better filtration for households with pets or mild allergies. MERV 13 captures even finer particles such as smoke, bacteria, and allergens—ideal for more sensitive environments. The higher the MERV rating, the finer the filtration, though it's important to ensure your system supports higher ratings.
Why is a proper filter size like 14x24x1 so important?
Using the correct size ensures a snug fit that prevents air from bypassing the filter, which improves particle capture and helps your HVAC system operate more efficiently and with less strain.
Can a high-quality filter lower my energy bills?
Yes—based on Filterbuy’s field data and independent studies, a clean, well-fitting filter reduces system strain and improves airflow, which can lower energy usage by up to 10–15% over time.
