Deionization Filter - DI Polishing Filter - For 10" Standard Filter Housing

Deionization Polishing Filter Cartridge

The DI-4 is a non-regenerable general-purpose deionization cartridge designed for use as an RO polisher for potable as well as laboratory grade water. The DI-4 has a carbon bed acting as a post filter to reduce TOC,taste, and odor. It is especially useful for polishing CA membrane RO water as it can remove free chlorine as well as CO2 gas.

The DI-4 is constructed totally from FDA grade materials and media. It can be used in recirculating mode or single pass. For best capacity, use two DI-4 cartridges in series.

Downflow operation is preferred. Intermittent up-flow may cause bed separation and quality failure. Continuous up-flow to exhaustion is acceptable.

Easy install, wide and sturdy

I put these shelves in a strange little cubby that was created in my kitchen by removing the sad excuse for a pantry that was once there. Super easy to hang, I’ve only hung two here and have other plans for the 3rd one. Good purchase for sure. Very sturdy and look expensive, without the high cost.

Great shelves!
Size: 12"D x 35.4"W, Color: Black
These were perfect for what I needed & easy to install with included hardware; looks great and looks like quality item. I like that they will hold 20 lbs so I can change what I place on them with no worries.

Sleek and attractive

While these didn't come in the color I was looking for, the size and price point were just what I was looking for. Installing them didn't take too long and was simple enough, but the end result did seem a little more wobbly than expected. I used them to display mine and my boyfriend's boots, and they held up fine, but I think 22 lbs per shelf would be pushing it. I was able to easily cover the shelves with wood grain look contact paper and easily trim the excess off with an Exacto knife to get the look I wanted. I'm happy with how it turned out.
