2-Pack Refillable Mixed Bed DI Resin Filter Cartridge Fits wide style 3.15" openings standard 10" size WH Filter Housings and Systems, Car Wash, Window Cleaning, Aquarium

Bought this for 10x2.5in filtration system, cartridges were about 1/2” too tall. Ended up ordering empty canisters that would fit and salvaging the DI resin, filtration could not drop below .60TDS. DI resin has strong fishy odor. Money wasted. Save your self the trouble, don’t order.

I purchased this resine at end of 2023 and installed it recently (end of July 2-24)… keep it in a dry place in its original packaging. Within 15 days, the résine started to turn blue over the lower quarter of each cartridge (I placed two cartridge into two housing conceited in series to get a near zero TDS on my RO system… my water started smelling like rotten fish last week. After a careful investigation, I found that it was this résine. Apparently, once saturated, it release a chemical coupoir d because of the die or something like that… anyway, even with a carbon filter, the stink was horrible, especially with heated water. I had to remove all cartridge and carbon block, and even change some pipes…. Buyer beware

I followed the installation and usage instructions. Even went so far as to put a water pressure regulator inline and also used a water flow control so the pressure never exceeded 50 PSI and the water flow never exceeded 2 gpm. Using a TDS metering device, the incoming water was 150-155 ppm and after passing thru the dual filters the best reading was 30 ppm TDS.I tried reaching out to the company via their website and 1 week later I've not received any type of response.Before the end of this week (in the next 3 days) I will try executing a refund request thru Amazon.I did submit the refund request which was accepted. I used the return label provided and it is on the way back to the seller/manufacturer.Update - After withholding 40% of the refund for "restocking fee" I recommend you avoid this company/storefront at all costs. They claimed the reason for the refund was "customer return" and ignored the fact the product was defective and didn't/couldn't meet the promised 0 ppm TDS.

Be aware does not fit culigan filter housings and broke the filter. This sent the resin all through my system.

I use this for a RODI setup for window cleaning. From 385 TDS to 0.
