Filter Selection Guide
The following handy filter selection guide will start you on your way to selecting an appropriate filter for your application. To use the guide, first identify your application area in the chart. Scan down the “Typical Applications” column to the category that most closely matches your intended
use. Then scan over to the left column. This will give you the MERVE value. Finally, scan over to the far right-hand column to see your selection of filters. This will give you a place to start but keep in mind that this is not a specific recommendation for a filter for a specific application. Rather, it is a starting point. Please contact us for specific filter recommendations. For an explanation of MERV values, see this publication.
