I would consider them ongoing consumables. The lifespan of many filters is measured in days or months, not years, which seems to put them on the shorter-term scale. And they are a consumable product, not a "durable" one.The important thing, as you probably know, is to make a consistent determination one way or the other.

John, After speaking to a few haulers and vendors in California, we found that there is not a method in place for recycling filters. We've been looking for a place to take used filters to be recycled. Can you please provide more information?

Hi Andy, The complete composition of the filters are metal framed, plastic holding parts perpendicular to the filter (kinda' inside the frame), pleated filter cell w/ a mesh of bent wire holding the filter fabric in the direction of the air flow. Currently the project team's maintenance contractor dismantles all the AHU filters into its basic components. These are then stored in separated boxes and then are periodically given to a waste hauler for recycling. A very dedicated team! Reminds me of doing that to carpet sample binders in the garage just yesterday to ship back to the manufacturer. I evaluated the materials based on consistent determination within the entire project submittal rather than if the material was exactly "ongoing" vs "durable". As a project team member, however, I would have placed them in ongoing consumable per Tristan's thoughts, though these types of filters (international project) last longer than the ones we typically think of.
