Designed as a direct-fit compatible replacement for a wide range of spa and hot tub models, the POOLPURE 5CH-352 combines a large filtration area and upgraded trilobal fabric to trap fine debris and help keep water clear.

This listing is for a POOLPURE independent-brand replacement; original equipment manufacturer names are provided only for reference to compatible part numbers.

How does this filter capture fine particles?

The cartridge uses trilobal synthetic fibers arranged to increase surface area and improve particle retention without excessive back pressure. Its rated nominal capture is around 50 microns, which helps remove hair, grit, sediment and other small debris that cloud spa water.

• 35 square feet of filtration media for more dirt-holding capacity
• Trilobal fabric structure increases surface contact and particle capture
• Nominal 50-micron performance for fine sediment and organic debris

Is the 5CH-352 compatible with my spa model?

This POOLPURE cartridge is built to fit many common hot tub and spa makes that accept 2" male-thread cartridges. Check your existing filter length and thread type; the 5CH-352 measures about 12 3/16" long with a 5 1/4" outer diameter and a 2" MPT bottom.

• Overall length: 12 3/16" — compare to your current cartridge
• Outer diameter: 5 1/4" and 2" male thread base for standard MPT housings
• Compatible references include common OEM part numbers for cross-checking

How do I install, clean, and maintain these cartridges?

Installation is straightforward: turn off the pump, unthread the old cartridge, and screw the POOLPURE cartridge into the 2" MPT port until snug. Monthly rinsing with a hose or periodic deep cleaning with a filter cleaner will preserve flow and extend service life; the reinforced handle eases removal.

• Turn off circulation before removing or installing
• Rinse monthly; use a specialty cleaner for deep soiling
• Not designed for backwashing — backwashing can damage the cartridge

How long will the filter last and what makes it durable?

POOLPURE engineered thicker filtration fabric and robust end caps to withstand regular chemical exposure and handling. The result is improved longevity versus standard cartridges when maintained properly, though frequency of replacement depends on use, water quality and maintenance habits.

• 25% thicker filtration fabric than many standard cartridges
• Chlorine-resistant, impact-resistant end caps reduce cracking
• Expected longer service life with routine cleaning and proper use

Who this is for: The POOLPURE 5CH-352 two-pack is for spa owners who need a reliable, easy-to-change replacement cartridge for 2" MPT systems. It suits anyone looking to restore flow and clarity without buying OEM-branded parts, including homeowners maintaining frequent hot tub use, property managers, and technicians who stock common compatible filters.
