Calcite Filter Cartridges for Neutralizing Low pH Water

pH Neutralizer Cartridge - 100% Calcite - For 20" Big Blue Filter Housing


AMI calcite filter cartridges are filled with 100% calcite media to naturally remineralize acidic drinking waters, raising the pH and alkalinity to a non-corrosive equilibrium. Calcite, a naturally occurring mineral, is self-limiting - dissolving only enough to increase the water's alkalinity to reach a non-aggressive, non-corrosive level. Applied Membranes calcite mineral cartridges are designed to fit standard filter housings for ease of compatibility - H-F4220CALCITE is 20" length and fits inside of a 20" Big Blue filter housings (actual outside dimensions of these housings are approximately 7.5" OD x 22" H).


Features and Benefits of AMI Calcite Filter Cartridges

  • Built-in 20 micron spun-bonded polypropylene post filter to prevent media fines from being washed out of the filter cartridge
  • Raises pH of water to a non-corrosive equilibrium
  • Reduces Leaching of Metal Plumbing Components and Copper Piping
  • Contains 100% calcite filtration media, a naturally occurring mineral
  • Low uniformity coefficient for maximum contact
  • Slower Reacting for controlled pH correction
  • Standard Cartridge Design Fits Most Standard Residential and Commercial Filter Housings

Functional divider for windows privacy
Size: 8 Panel, Color: White, Size: 8 Panel, Color: White
I ordered both a six and eight panel version of the white divider. There was some confusion on the FedEx deliveries. The eight panel divider arrived at first, but Amazon showed both as delivered. I had to contact both the seller and Amazon to learn that the six panel divider was to arrive the following day by FedEx, which did occur. Both the boxes were a bit dirty and had some small punctures. This divider had a top area and bottom area set of plastic wrap tapes, both of which were loose or undone. (The eight panel divider was not so, and properly wrapped.) The top of thid divider looked a little dirty, but passable/cleanable. The seller should consider wrapping the entire product with bubble wrap to protect against potential delivery/shipping physical and water damage. (FedEx left the box by my outside door, which could have gotten potentially soaked in rain. One better be home to take delivery if the weather is bad.) This said, the divider was easy to set up, with all the metal hinges working. No assembly was required, just unboxing and standing up. The left side was a little uneven on the bottom with the first panel, but ok. In combination with my mini-blinds, it provides the additional layer of privacy I desired. I even don't notice outside headlights and tailights through the windows with my room lights on. Additionally, the divider is easy to adjust to allow access to my windows for opening and closing. So, no need for me to hang curtains and damage my drywall. Overall I give the product a C grade because of the lack of protection for the FedEx shipping. (As a former University told me years ago, "The A has been cheapened. In this class you will work for an A." And, I got a B. So, I am a bit jaded. :-)) Lastly, if one had cats and dogs, or even small children, the divider could be easy for them to topple over. I would not consider these dividerd in that case. My motto is, "Safety first."

Nice quality, looks brand new even with daily use! Worth it!
Size: 6 Panel, Color: White
I got the Rose Home 6 panel room divider folding privacy screen and I LOVE it. I use it every day - extending it out to both block the sun, provide a backdrop for my plant wall, use as a backdrop for zoom calls, create privacy at night in front of the big windows and clear doors, and make impromptu study privacy walls in the office. This 6-panel has been the GOAT! Even though the screen is made of a woven paper material, it is still going strong despite daily use and has NOT broken anywhere. The frame is taller than other folding screens I've purchased and this one is also heavier and sturdy. Additionally the hinges fold open in BOTH directions (some screens only fold open in 1 direction like a Z). I use the folding screens indoors, but they have no issue with the AC or fans for wind resistance indoors. Sometimes I use them to hide storage or junk in the corner and make the room look neater. I also have a different brand that is the same material but has 8 panels and I love them both. I got 2 others that were made from synthetic canvas webbing belt/leash fabric and those break so fast - I just had to throw 1 away. This one is worth the money, even after daily use, it looks brand new!

Already assembled!
Size: 8 Panel, Color: Natural
Came way sooner than the estimated delivery date and it looks awesome! Biggest plus is it came ALREADY ASSEMBLED! I was expecting self assembly but maybe that's on me for not reading the specifics. Hoping it's the right size for my new studio apartment. So far the look and functionality is 10/10
