What size air filter do I need?

Read the size printed on the frame of the one you are replacing, or measure the slot it sits in. Filter sizes are NOMINAL and rounded - a filter sold as 20x25x1 actually measures about 19-1/2 x 24-1/2 x 3/4. Buy by the nominal size printed on the frame, not by what your tape measure says.

Which way does the arrow point?

Toward the blower - the same direction the air is travelling, away from the return grille. Installed backwards the pleats collapse and airflow drops.

Is a higher MERV always better?

No. MERV measures how fine a particle the filter catches, but finer media also restricts airflow. Most residential blowers are happy at MERV 8 to 11. Going higher than the system was designed for trades dust for airflow problems - long run times, a frozen coil, or short cycling on the limit.

How often should I change it in Dallas?

Check a 1 inch filter monthly and change it every one to three months - sooner with pets or during cottonwood season. A 4 inch media filter usually runs six to twelve months. Dallas dust and a long cooling season are hard on filters.

What is the difference between a 1 inch and a 4 inch filter?

A 4 inch filter holds far more media, so it catches more, restricts airflow less and lasts much longer. It only fits if your cabinet or filter base has a 4 inch slot - a 4 inch filter will not go into a 1 inch rack.

Do you have my size on the shelf?
