What are High Flow Return Grilles?
A high flow return grille is also called a fixed bar type return grille.
What's the differnce?
There are two types of return filter grilles that are used in residential homes. There is a fixed bar type grille, and a stamped face grille. A high flow return grille (or fixed bar return grille) is type of return grille that is much more aerodynamic than a stamped face return grille. The louvers positioned on a fixed bar return grille are further apart, and are designed much more aerodynamically than those of a stamped face grille. A high flow return grille (or fixed bar type return grille) has essentially more open area to let air flow through the actual grille.

Why Does This Matter?
We care about this for multiple reasons.
- Reduce static pressure- lower bills and increase lifespan of equipment
- Less noise- ever hear a whistling sound, or noise coming from the return grille when your equipment is running? Upgrade to a properly sized fixed bar return grille and the noise will be gone
- Increased airflow- a great effective surface area of a return grille means greater comfort throughout your home
