Zephyr filters provide excellent value — quality filtration at a fair price.

Why Regular Filter Changes Matter

A clogged filter restricts airflow, forcing your system to work harder and use more energy. Over time, restricted airflow can cause evaporator coil freeze-ups, compressor strain, and premature equipment failure. Most 1-inch filters should be replaced every 30 to 90 days depending on usage, pets, and air quality conditions. Stock up so you always have a fresh filter ready.

Frequently Asked Questions

How often should I change my HVAC filter?

Standard 1-inch filters should be changed every 30 to 90 days. Homes with pets, allergies, or heavy use should lean toward the 30-day side. Thicker 4-inch filters can last 6 to 12 months depending on conditions. Check your filter monthly and replace it when it looks dirty.

What MERV rating should I use?

For most residential systems, a MERV 8 to MERV 11 filter balances good filtration with adequate airflow. Higher MERV ratings catch smaller particles but can restrict airflow if your system is not designed for them. Ask our staff for a recommendation based on your system and needs.

Do you carry uncommon filter sizes?

We stock all standard residential sizes. If you need an unusual dimension, call ahead at 214-340-9421 — we may have it in stock or can order it for you quickly.
