Navigating Nominal vs. Actual Filter Sizes The nominal size is a rounded whole or half inch number, while the actual size reflects the filter's precise dimensions. Both are provided to ensure proper fit.

Measuring Your Air Filter If no size is listed, measure the width, length, and depth, then round up to the nearest inch to find the corresponding nominal size.

Why Change Your Air Filter? Replacing filters maintains indoor air quality, preventing respiratory issues and system inefficiencies that lead to higher energy costs and repairs.

When to Change Your Air Filter? Generally, we recommend replacing every 3 months, but frequency may vary based on factors like pet ownership, allergies, and household occupants.

Ensuring a Proper Fit Our filters are universally compatible with most HVAC systems. However, double-check for brand-specific compatibility if noted.

Determining the Quantity Needed The required number of filters depends on your home's ventilation setup. Our packages range from 1 to 12 to accommodate diverse needs.

Changing Your Air Filter After identifying the right size, simply power off, remove the old filter, insert the new one matching airflow direction, replace the cover, and restore power.
