COMMON FAQ'S

Frequently
Asked Questions

Find quick answers to the most common questions about choosing, sizing, and replacing your air filters.

How often should I change my filter? +
It depends on filter size, MERV rating, and your home’s conditions. Most 1” filters should be changed monthly, 2” filters every 2–3 months, and 4–5” filters every 4–6 months. If you have pets, allergies, or high system use, you may need to change them more often. Some high-efficiency filters can last 6–12 months in mild conditions. Always check your manufacturer’s recommendations for the best schedule for your system.
What is the difference between nominal size and actual size? +
Nominal size is the rounded measurement used for labeling (for example, 16×25×1), while actual size is the filter’s true, slightly smaller dimension (such as 15.5×24.5×0.75). Filters are made slightly smaller than their nominal size so they fit properly in your system. Always check the actual size if you need a precise fit.
What is a MERV rating and what should I choose? +
MERV (Minimum Efficiency Reporting Value) shows how well a filter captures particles between 0.3–10 microns. A MERV 8–11 is a great balance for most homes (dust, pollen, pets), while MERV 13+ is better for allergy, asthma, or smoke concerns — if your HVAC system can handle the higher airflow restrictions.
Do higher-rated filters harm my HVAC system? +
They can if your system isn’t designed for them. Higher MERV filters block more particles but may reduce airflow. Always check your system’s specs or manual before moving up.
