Choosing the Correct Filter Size

Nominal Size vs. Actual Size The nominal size is a rounded shorthand number (ex: 16 x 20 x 1), while the actual size is an exact measurement (ex: 15.50 x 19.50 x 0.75). All filters have both.

Measuring Your Air Filter If your current air filter doesn't have dimensions listed, use a tape measure to record the width, length, and depth to find the actual size. Round up these measurements to the nearest inch to find a corresponding nominal size, making it easier to search online.

Why should I change my air filter? To maintain a healthy lifestyle. Breathing dirty air can lead to asthma, allergies, and other respiratory ailments. Additionally, old filters can cause system defects, resulting in higher energy costs and repairs.

When should I change my air filter? We generally recommend replacing your filter every 90 days for optimal efficiency and clean air. However, this may vary based on filter size and specific factors such as pets, allergies, and children in the household.

Will these air filters fit my system?
