Ordering Electrostatic Air Filters

Throughout the year we have numerous customers call about the difference between custom and standard filters. It’s important to remember when ordering filters to make sure that you take the time to order the correct size and type of filter.

All custom filters are cut to the exact measurements of the sizes that are entered in the online ordering system. You have to allow for a 1/8” overall manufacturing tolerance on both custom and standard filters. Custom filters cannot be returned, so be sure your are accurate in entering measurements.

All standard filters are a nominal cut, meaning we undercut 3/8” from the size listed. All standard filters can be returned as long as they are still in the original shrink wrap and have not been used. Standard filters are subject to a 20% restocking fee and return shipping at your expense. You must call prior to returning filters to obtain a return authorization number from our customer service department.

All of our filters are offered in arrestance rates of 82% & 94%. The difference between these are: 82% percent has one less layer of polypropylene which allows more air to flow through but it will collect less debris than the 94% which has the extra layer of polypropylene and will collect more debris.

We also offer 3 types of filters: Gold Frame, Silver Frame or Flexible Frame. Our Gold filters have a rigid frame and the polypropylene material is UV resistant, which means that if you have a UV light in the system you need to use this type of filter. Silver filters have a little more give to them and the flex filters have no rigid frame around the material.
