The 3M™ Aqua–Pure™ Whole House Large Sump Replacement Water Filter Drop–in Cartridge AP817–2 is a large diameter 2–high 4–5/8" diameter by 20–1/8" drop–in cartridge that is manufacturer tested and verified to reduce sediment to 25–µm nominal1.

Importantly, this drop–in cartridge also reduces chlorine taste and odor1 for cleaner, clearer and better tasting water. Here’s how it works – the rigid outer shell construction helps capture sediment while retaining the granular activated carbon which is used to reduce chlorine taste and odor. It’s ideal for larger homes with at least 2.5 bathrooms. Features include: Flow rate up to 20 gpm/75.71 lpm (housing dependent), 6 months (varies depending on local water quality), 4 ⁵/₈"/11.75 cm by 20 ¹/₈"/51.13 cm, 25 to 125 psi/172 to 862 kPa pressure range, 4.4...37.8 °C (40...100 °F) temperature range.

To maximize system performance and efficiency, regularly scheduled maintenance including replacement of the filter cartridges at the required interval, at the rated capacity, or sooner if a reduction in water flow occurs is required. Filter life is dependent on actual use and incoming water quality.
