Easy to Assemble. It uses a simple, three-step assembly process that is much faster than other expandable filters on the market. Other expandable filters can take up to 15 minutes to assemble, requiring the installation of up to five combs (pleat spacers). The patented design of the EZ Flex does not require combs and assembles in less than 15 seconds. Three easy steps:

1. Simply remove the filter from its box and expand to full size.
2. Place one of the re-usable end pieces on a flat surface and insert the expanded filter.
3. To complete assembly, place the second end piece across the opposite side of the filter.
