What is the difference between an HVAC and a HEPA filter?

HEPA is a High Efficiency Pleated Air filter with small tightly pleated media and high MERV ratings.

What is a MERV rating?

A MERV (Minimum Efficiency Reporting Value) is a measure of how effective an air filter is. Filters with higher ratings can prevent finer particles from getting through than filters with lower ratings. An example of a lower merv rating filter (MERV 1-4) would be a simple throwaway fiberglass or synthetic panel filter. An average filter (MERV 8) could be a pleated filter with cotton/polyester blend material.

What is filter foam?

Filter foam is a reticulated foam that has open cells to allow air or liquid through it.

How often should I replace my filter?

This depends on the type of filter you have. If you have a fiberglass air filter, you'll want to replace it roughly every month or so. If you have a pleated air filter, you'll want to replace it roughly every three months, depending on use. Please review your owners manual or consult with the manufacturer or supply representative if you are unsure of the replacement schedule.

What type of foam can be die cut?

Soft flexible polyurethane up to 2” thick may be die cut to meet your needs.
