WHOLE HOUSE MULTI MEDIA WATER SYSTEMS KDF 55 Media Guard - GAC Coconut Shell Carbon

KDF 55 Media Guard

KDF-55 filter media consists of finely granulated copper and zinc alloys. The combination of these two alloys in the media allows the chemical reaction of redox (Oxidation-Reduction) to take place when water passes through the media. Redox involves the transfer of electrons between two molecules, changing these molecules into entirely different elements. In the KDF process, electrons are taken from harmful contaminants like chlorine and microorganisms. This loss of electrons changes contaminants into far less harmful, or even harmless, elements. For example, chlorine-- when it loses an electron in a redox reaction--is changed into the harmless, water-soluble chemical chloride. While there are several different KDF media, KDF-55 is designed to specifically remove or reduce chlorine, heavy metals, and microbiological contaminants. When a KDF-55 filter media is used during the first stage of filtration (as is the case with our mixed media filter) the life of the entire filter unit is greatly lengthened. Translation of water contaminants into harmless elements in the first stage reduces the amount of scaling and bacterial growth that will take place on the more expensive carbon filter media of subsequent stages. Also, the preliminary reduction of contaminants allows the absorptive process of the carbon media to focus on more harmful and elusive contaminants.

1.5 CU FT OF GRANULAR ACTIVATED CARBON:

Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can absorb literally thousands of different chemicals. Activated carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the of the contaminants are drawn to the surface of the carbon granules. Activated carbon filters used for home water treatment typically contain either granular activated carbon or powdered block carbon. Although both are effective, carbon block filters generally have a higher contaminant removal ratio. The two most important factors affecting the efficiency of activated carbon filtration are the amount of carbon in the unit and the amount of time the contaminant spends in contact with it. the more carbon the better. Similarly, the lower the flow rate of the water, the more time contaminants will be in contact with the carbon, and the more absorption that will take place. Particle size also affects removal rates. The most common carbon types used in water filtration are bituminous, wood, and coconut shell carbons. While coconut shell carbon typically costs 20% more than the others, it is generally regarded as the most effective of the three. All of our activated carbon filters use coconut shell carbon. There are two principal mechanisms by which activated carbon removes contaminants from water; absorption, and catalytic reduction, a process involving the attraction of negatively-charged contaminants ions to the positively-charged activated carbon. Organic compounds are removed by absorption and residual disinfectants such as chlorine and chloramines are removed by catalytic reduction. Activated carbon filtration is very common in a number of home water treatment systems. It can be used as a stand alone filter to reduce or eliminate bad tastes and odors, chlorine, and many organic contaminants in municipal (pre-treated or chlorinated) water supplies to produce a significantly improved drinking water. It is also very commonly used as a pre-treatment as part of a reverse osmosis system to reduce many organic contaminants, chlorine, and other items that could foul the reverse osmosis membrane. 0.5 block filters are commonly used to remove cysts such as giardia and cryptosporidium. Activated carbon filters remove/reduce many volatile organic chemicals (VOC), pesticides and herbicides, as well as chlorine, benzene, trihalomethane (THM) compounds, radon, solvents and hundreds of other man-made chemicals found in tap water.

good value and battery life
Color: Purple
Love this!! the keyboard has a good life on it and charges pretty fast. I at first didn't really like that it detaches, but being able to hold the keyboard in my lap and type on the screen while I sit on the sofa is actually pretty nice. the trackpad does have a bit of a learning curve, but gestures/hotkeys are all listed on the bottom so it's easy to check whenever necessary. The material of the case itself also cleans really easy. I spilled a drink on it and it wiped right off. I feel like this is a pretty good value all things considered, especially when similar products at big box stores can eb a couple hudnred bucks. The only downside is that the keyboard, while slim, does add a bit of bulk to the case. It's not a huge deal for me, but my boyfriend who also has an ipad did notice the difference immediately.

Works
Color: Light Gray
Heavy! It is a nice case and the keyboard works good. Turns off randomly, but not too annoying. This case is heavy though! It at least triples the weight of my iPad, which is opposite the reason I got an iPad Air. Too late to return, I just take the keyboard out, but it must be the magnets in the case that are so heavy.

Fantastic keyboard!
Color: Navy Blue, Color: Navy Blue
Pleasantly surprised!! And less than half the price of an ipad folio keyboard - I know, one feels like one has to stay in brand. So I was nervous about buying a keyboard that wasn't made by Apple. But to be honest, the Apple keyboards and mice have betrayed me on numerous occasions. They have not earned my loyalty and need to reassess their dubious life choices. I needed a protective cover to stop my cats doom scrolling while I am asleep. I am OK with them using the internet - even though I have had random people text me back a picture of a large feline left nostril and just the letters WFT? It is what it is. I think they are little geniuses. But they scratch the ipad surface which is annoying. So I thought, what the heck - I am about to do my RN-BSN online and need a way to make my ipad transportable while protected, and set up so I can easily bang out some homework assignments on the run. Easy set up! What a relief! Tech usually hates me - sees me coming from a mile off and starts planning to at best ruin my day, and at worst have me calling my therapist. At first I started reading the instructions and my teeth hurt from the bad translation into English. But even with that negative energy I was able to set it up very quickly. Everything just WORKED!! I know. I set a low bar. These days one has to. This time I didn't need to. The cover is sturdy, soft and coffee resistant, thank goodness. The keyboard just plops on, connects through magic and immediately makes me feel like I am not as stupid as I thought! Absolutely recommend this wonderful keyboard - I dunno who do this voodoo but I am very excited. Crack on my lovelies! Make those dreams a reality.

Great product!
Color: Light Pink, Color: Light Pink
I really love this. The baby pink is so cute! I had my hesitations because I couldn’t see if the pink would be as good in real life. It’s like a soft blush color. Honestly, I was going to drop $350 on the Magic Keyboard for my iPad Air. Which is ridiculously expensive. This is a way better alternative. It fits my iPad pen. The iPad itself fits perfectly. I thought the keyboard was going to be tacky and cheap. But it’s pretty legit too. I love that when I’m done using the iPad, the whole case protects everything, even the keyboard inside and especially the camera lense. The magic key board does not have that feature. Like that it’s magnetic too. The material is so soft to touch. I can see how it can get dirty with ink spot if not careful. Overall, really happy with this purchase!

Sleek, Functional, and Feels Like a Laptop Replacement
Color: Navy Blue
I’m really impressed with this keyboard case. The magnetic attachment is strong and secure, and the keyboard connects quickly without any issues. The trackpad is smooth and responsive, which makes using the iPad feel almost like a laptop. The backlit keys are a great touch, especially with the different color options, and the lighting is even and easy on the eyes. The case itself feels well made and protective, and I like that it’s stain resistant because it stays looking clean. The navy blue color looks sleek and professional. It fits my iPad perfectly and doesn’t add unnecessary bulk. Battery life has also been solid so far. Overall, this is a great value for the quality and features you get. Highly recommend if you want a reliable keyboard case that’s both functional and stylish.
