What to check before you order

This page does not say this part works in any particular housing or swaps for any other brand's part. Before ordering, compare these against what you use today:

  1. Size. This part is 4.5″ × 20″ (diameter × length). Check your housing's cartridge size or the label on the part you use today.
  2. Micron rating. 25 Micron nominal. If your specification calls for an absolute rating or a particular rating type, say so in your request.
  3. Media. Mixed-bed deionization resin (ResinTech® MBD-10-SC). If the part you use now has a different media, flag it so the change is a conscious one.
  4. End style and seal. The manufacturer data we hold does not list end caps or gaskets for this part. If your housing needs a spring seat, a fin end or a gasket, tell us.
  5. Certification. If your specification requires NSF/ANSI 61 or 42, put that in your request.

Our spec comparison guide walks through each item.
