Why we chose it

Its replacement cartridge has a published lab test for chlorine reduction, and Crystal Quest documents operating limits and care steps in detail.

What is included

The filter housing with the cartridge, a spare O-ring and a flow-restricting gasket already inside, plus plumber's tape (Crystal Quest).
Choose 'With Shower Head' to add a shower head.

Will it fit my shower?

Crystal Quest says the filter connects to any standard shower arm with ½-inch NPT threading and takes a standard shower head.
Assembled with its head it measures 8 × 3 in; the housing alone is about 5.1 × 2.9 in. Flow rate 2 gpm.
Operating pressure: 30 to 60 psi. Water temperature: 40 to 110°F.
Choose 'With Shower Head' to include a shower head, or 'Without Shower Head' to use your own.
Not intended for outdoor use (Crystal Quest).

Filtration details

Its replacement cartridge (CQE-RC-04045) was tested by QFT Laboratory to NSF/ANSI 177 for chlorine reduction in 2020 (report 20-730): about 72 to 89 percent reduction at 1.5 gallons per minute through 500 gallons of room-temperature test water. This is a test report, not a product certification.
Not designed to treat hardness (it is not a water softener), bacteria and viruses, fluoride, nitrate or total dissolved solids. Use only on microbiologically safe water.

Installation & care

Crystal Quest says installation is done by hand, with no tools: wrap 2 to 3 layers of the included plumber's tape clockwise around the shower arm threads, then tighten hand-tight plus a quarter turn.
After installing a new cartridge, run hot water through the filter for 2 to 3 minutes to flush loose media fines, which are normal in a new cartridge. More than one flush may be needed. Let the water cool before you step in.
At each cartridge change, check that both housing O-rings sit in their grooves and coat them lightly with a non-petroleum oil (not coconut oil).
Between changes, you can reverse the cartridge in the housing to back-flush the media.
Protect the filter from freezing and direct sunlight.

Replacement guidance

Crystal Quest recommends a new cartridge every 6 to 12 months, or sooner if water flow drops or a chlorine smell returns. Actual life depends on feed water quality, system configuration and usage. In hard-water areas, plan on the shorter end of the range.
The matching part is the Crystal Quest Shower Filter Replacement Cartridge (CQE-RC-04045).
