(3 Pack) Mixed Bed Ion Exchange Aquarium Filter Resin 0 PPM RO DI Refillable Housing w/Clamps & Fittings, Compatible with 10" Reverse Osmosis Water Filtration Systems, for High TDS in Water

Provides greatcspot free rinsing

Connected with only two adapters (from Home Depot) to my RO system output. Decent price, and on time delivery.

Nice compact unit. You do need to buy 1/2 inch connectors for it to connect your 1/4 inch plastic piping into. You also need to make sure to add teflon tape and tighten the ends firmly or you may get a leak. Also make sure to pay attention to the hard to see arrow on it, which indicates the flow direction.

Meant to return this but forgot & missed the window. At least it's refillable, but if you're purchasing additional mixed-bed DI resin anyway then you might as well go with a transparent 10" x 2.5" housing and refillable DI canister. This product will not work with all this headspace, water will easily flow over rather than through DI resin, particularly in a typical horizontal orientation. This housing will need to be tightly packed with additional mixed-bed DI resin to be effective. Further, the resin included appears to contain odd bits of strange debris. Factor $50+ for additional mixed-bed DI resin into your decision with this purchase & it'll then be worthwhile if you require this style of housing.Does not include the pictured quick-disconnect fittings, just bare FNPT on each cap end.
