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:
- Size. This part is 4″ × 40″ (diameter × length). Check your housing's cartridge size or the label on the part you use today.
- Media. Thin-film composite (TFC) polyamide. If the part you use now has a different media, flag it so the change is a conscious one.
- Certification. If your specification requires NSF/ANSI 61 or 42, put that in your request.
Our spec comparison guide walks through each item.
