Aqua-Pure™ AP917HD-S Sanitary Quick-Change Whole House Water Filter Cartridge - (5621008)

Overview

The AP917HD-S is a high-performance replacement cartridge designed for use with the Aqua‑Pure AP900-series whole-house filtration systems (specifically the AP904 system). It combines heavy-duty sediment reduction, carbon block filtration for taste/odor control, and scale inhibition, all in a Sanitary Quick Change (SQC) design for fast, clean cartridge swaps. 

Key Features & Benefits

• Multi-Stage Filtration: The cartridge incorporates a non-woven pleated media for sediment reduction (nominal 5 microns) plus a carbon block filtration layer for chlorine taste & odor control, and scale inhibitor media to help reduce hardness scale build-up in applications like water heaters.

• High Flow Capacity: Designed to handle whole-house flow rates up to 20 GPM (≈ 75.7 L/min) under peak conditions, making it suitable for larger homes or light commercial use. 

• Large Capacity: The cartridge is rated for about 100,000 gallons (~378,540 litres) of treated water under typical conditions, or an approximate 12-month service life depending on water quality. 

• Sanitary Quick Change (SQC): Enables fast, tool-free cartridge replacements without having to contact the filter media, which helps improve hygiene and ease of maintenance. 

• Robust Construction: The AP900-series head is made with 304 stainless steel for corrosion resistance and allows “sweat-in” installation on copper piping for durable whole-house service.

• Versatile Application: Suitable for both chlorinated municipal water and non-chlorinated well water systems, given the multi-media design.

Specifications (at a glance)

• Micron rating: 5 µm nominal. 

• Flow rate: Up to ~20 GPM (≈ 75.7 L/min) in peak/off-cycle conditions; typical continuous service up to ~10 GPM. 

• Rated capacity: ~100,000 gallons (~378,000 L) under typical conditions. 

• Operating temperature: approx 40°F to 100°F (4.4°C to 37.8°C). 

• Pressure range: typically 25-125 psi (172-862 kPa).

• Compatible system: AP904 and AP900-series whole-house systems.

Why Choose This Cartridge?

If you’re looking for a reliable, high-capacity whole-house filtration upgrade that addresses not only sediment and chlorine taste/odor but also potential scale issues, the AP917HD-S is a strong option. Its SQC design makes maintenance easier and cleaner than conventional large house filters, while the high flow rating means you can maintain strong water performance across multiple bathrooms or heavy usage without drops in pressure.

Maintenance & Tips

• Replace the cartridge every 12 months or when a noticeable drop in flow or change in water taste/odor occurs. Water quality, usage, and inlet sediment levels will affect actual life.

• When installing, ensure proper shut-off and depressurization of the system, then follow the SQC cartridge swap procedure to avoid contact with spent media.

• For homes with very heavy sediment loads or well-water conditions with high particulate content, consider installing a pre-sediment filter/upstream sediment trap to extend cartridge life.

• Keep a maintenance log of the replacement date, approximate gallons treated (if available from usage estimates), and any observed changes in flow or water quality.

• Ensure the filter head and all plumbing connections remain free of corrosion and that O-rings are properly seated when replacing the cartridge, to maintain leak-free performance.
