Helpful Info About Our Air Filters

This month, we are passing on a little information regarding our Electrostatic Air Filters.  When speaking to our customers, we are often asked about the difference in filter type, size and arrestance.  Here’s some information that might help you when determining what your customer needs.

Custom filters
  – are cut to the exact measurements that are entered when you are ordering online.

Standard filters
  – are undercut by 3/8″ from the size listed.  Keep in mind you should allow for a 1/8″ overall manufacturing tolerance.

We offer 2 types of arrestance; 82% and 94%. The 94% arrestance filter has a higher filtering capacity whereas the 82% is slightly less but it is also less restrictive on the airflow.  If you are concerned about which one to choose, you can calculate the proper filter arrestance using the tab on our online ordering site, it is located right above the filter types after you login.

We also offer 3 types of filter frames; Gold, Silver and Flex.

Our Gold frame is a gold anodized extruded aluminum frame, that consists of 4 separate pieces fastened together by a screw in each corner.  These filters only come in a 1″ depth.

Our Silver frame is made of a single piece of roll-formed aluminum riveted together at each corner.  It slightly less strong and sturdy as the gold frame but, it is more cost effective.  These filters can be purchased in ½”, 1″, or 2″ depths.

Our 3rd option is the Flexible filters which are not made with aluminum frames but rather sewn with flexible polypropylene webbing around the edge.  This allows for use in tight fitting areas where bending the filter might be needed to get it installed.

One other thing to be aware of when it comes to our filters is production time. When you login and get to the filter page you will notice what our current production time is.  This is determined by how many filter orders we are currently working on.  We send out an average of 300-400 filters a day and try to keep production to about 2-3 business days, but this can change at any time, knowing this will help you determine when you or your customer should receive their filter.   Hopefully this should help!
