- Durable end caps and strong internal core structure for long service life.
- Open-top and open-bottom design for quick installation and secure seating.

Typical Applications
This replacement cartridge is ideal for residential in-ground pool systems using a 100 sq ft cartridge filter. It is used when the original cartridge becomes clogged, torn, collapsed, or when water clarity or circulation begins to decline.
Installation & Compatibility Notes
Turn off the pump and relieve pressure from the filtration system. Remove the filter lid or clamp and pull out the existing cartridge. Clean the filter tank body and check for any wear or cracks. Insert the new C-7499 cartridge, ensuring it is seated properly. Reassemble the filter, restore water flow and verify normal operating pressure.
Why Choose This Cartridge?
The C-7499 provides durable construction, consistent filtration, and a long service lifespan. Replacing worn cartridges helps maintain clear water, reduces strain on the pump, and improves overall system efficiency.
Maintenance Tips
- Check filter pressure regularly; clean or replace the cartridge when pressure rises 8–10 psi above the clean starting point.
- Rinse the cartridge thoroughly with a hose; soak in a cartridge cleaning solution periodically to remove oils and fine debris.
- Inspect pleats, end caps and center core for damage—replace immediately if compromised.
- Keep a spare cartridge on hand to rotate during cleaning and reduce downtime.
