How to measure your filter cartridge
If the number on your old cartridge has worn off, or you want to check a replacement for the PDM28, measure these four things and compare them with the product page.
- Length: from the outside of one end cap to the outside of the other. Leave out any handle.
- Diameter: across the end cap at its widest point, not across the pleats.
- Top and bottom openings: note whether each end is open (measure the hole), closed, threaded (for example 1-1/2 in male thread) or has a handle. Both ends must match.
- Filter area: printed on the label or end cap in square feet. A replacement should have the same area to fit your filter's flow rating.
