Engineered with friction-welded, no-glue construction and 3/8" quick connect fittings, it offers easy, leak-free installation. Ideal for upgrading reverse osmosis systems, it restores essential minerals and neutralizes acidity for healthier, better-tasting water. ## Description The PHPLUSKIT-38 cartridge is a super high capacity, naturally occurring PH increaser. It is for general drinking water pH increase purposes. It can also be used as an reverse osmosis polisher if desired (installed at the last stage). Since it is sacrificial, the calcite acid cartridge will add 2-5 ppm of hardness to the water. This is also an excellent way to reduce the corrosiveness low tds water. This filter is constructed totally from FDA grade materials and media. This calcite filter will deliver a neutral effluent form acidic feed as low as pH5. Low pH's require slower flow rates. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with Calcite, acidic water slowly dissolve the calcium carbonate to raise the pH.

Review: If you have a Reverse Osmosis (RO) drinking water system you should definately install one of these. The RO system is so good at removing impurities, it even removes all the minerals. While this might sound like perfect water, it is far from that. Without minerals in the water, when you drink that water, it will leach those minerals out from your bones. You see, water "wants" to be mineralized, which is why it leaches minerals out of the ground. This device will solve the problem. You will have drinking water with none of the nasties and all of the minerals, just like back when we were cavemen, and the cavewomen were dragging us into the caves by our hair for some R&R. I might have that part slightly wrong. So get you a RO system, install this hunk of loveliness, and you'll be ready to go T-Rex hunting! ## Features - Increase pH level of the water by adding calcium carbonate mineral back into the water - Made of 100% US-Made high purity calcium carbonate to effectively neutralized acidity - Friction-welded construction with no glues or binder to provide reliable, no-leak seal - 3/8" Quick connection fittings (for upgraded 3/8" output system) for easy leak free installation - A perfect add on filter to compliment any existing or new RO drinking water systems ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07GCB8N4G | | Brand | APEC WATER | | Colour | White | | Customer Reviews | 4.4 4.4 out of 5 stars (93) | | Date First Available | 15 Aug. 2018 | | Item Weight | 789 g | | Material | Carbon Fibre | | Model Number | PHPLUSKIT-38 | | Product Dimensions | 25.4 x 5.08 x 5.08 cm; 789 g | ## Product Details - **Brand:** APEC WATER - **External testing certification:** REACH, FDA - **Material:** Carbon Fibre - **Product benefits:** Increases pH Level - **Product dimensions:** 5.1D x 25.4W x 5.1H centimetres ## Images ![APEC PHPLUSKIT-38 US MADE 10" Alkaline High Purity pH+ Calcium Carbonate Inline Filter Kit with 3/8" QC (For Upgrade 3/8" Output RO System) - Image 1](https://m.media-amazon.com/images/I/31bzjWtxnBL.jpg) ![APEC PHPLUSKIT-38 US MADE 10" Alkaline High Purity pH+ Calcium Carbonate Inline Filter Kit with 3/8" QC (For Upgrade 3/8" Output RO System) - Image 2](https://m.media-amazon.com/images/I/41cOsnybY5L.jpg) ![APEC PHPLUSKIT-38 US MADE 10" Alkaline High Purity pH+ Calcium Carbonate Inline Filter Kit with 3/8" QC (For Upgrade 3/8" Output RO System) - Image 3](https://m.media-amazon.com/images/I/51F-PXgJbXL.jpg) ![APEC PHPLUSKIT-38 US MADE 10" Alkaline High Purity pH+ Calcium Carbonate Inline Filter Kit with 3/8" QC (For Upgrade 3/8" Output RO System) - Image 4](https://m.media-amazon.com/images/I/61rIfDUHtxL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***K on 15 November 2025* Great tasting water. ### ⭐⭐⭐⭐⭐ Review *by W***E on 9 January 2024* If you have a Reverse Osmosis (RO) drinking water system you should definately install one of these.

I purchased a warehouse deal to save a little money it was not used people don't understand also when they just buy the filter they just have little plugs in the end and they say it's not wrap well it doesn't need to be wrapped it's protected nobody used it before if they did water would come out of it. This lasts me about a year. Just one caveat the manufacturer answered in a question that made sense first thing in the morning let the filter run a little bit say about 45 seconds because water was sitting in the filter overnight which would cause it to be a little stronger with the minerals I also run the cold tap water at the same time so that water that was sitting in the pipe doesn't go into the RO system just to give it more life. Also a lot of people misconceive this doesn't really raise your pH if it is too low or too high it will balance it out. Also those pH meters are not really accurate I compared it to a alkaline water that was 8.8 and it showed higher about two points so I used my base from that. There is a lot of learn a lot about a RO system but this was my first one I bought from APEC on a warehouse deal I did upgrade it though to the 3/8 upgrade kit and it does come out a lot of faster at first for filling cups up or coffee pots saves me time. You do save money sometime on warehouse deal so keep an eye out I bought the yearly up graded filters in a kit that included the membrane and and a finishing filter for under the price of just those upgraded filter so I'm good for when I need to change the membrane. They are kind of expensive these mineral filters at full price but you can also go to the company's website at free drinking water dot com and maybe get a cheaper when they have sales. But it does taste a lot better than being just stripped water which I don't like but as I may have said look at a plastic bottled water and see the ingredients.
