WHOLE HOUSE MULTI MEDIA WATER SYSTEMS KDF 55 MediaGuard - GAC 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.

2 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.

Light, Moisturizing, and Smells Great, Totally Worth It
Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1)
I’ve been loving this Neutrogena Beach Defense sunscreen. It goes on so smoothly and feels more like a light body lotion than a typical sunscreen, which I really appreciate. It’s super easy to apply and doesn’t leave that sticky or greasy feeling that a lot of other sunscreens do. My skin actually feels hydrated after I use it, which is a nice bonus especially when I’m out in the sun all day. The scent is fresh and beachy, not overpowering or too “sunscreen-y,” and it fades nicely after a while. It also absorbs quickly and doesn’t leave a white cast, which makes it great for reapplying throughout the day. I’ve used it at the pool, the beach, and just for everyday sun protection, and it’s held up really well every time. It’s a little pricier than some drugstore sunscreens, but honestly, the quality makes it worth it. It feels good on my skin, protects well, and doesn’t make me feel gross after hours in the sun. I’ll definitely be picking up another bottle when this one runs out.

Protected Our Skin and Smells Good
Size: 6 Ounce (Pack of 1)
I love this stuff! My husband and I bought it as a last minute grab for our honeymoon and it was well worth it! I'm very sensitive to the sun AND to sunscreens, so I needed something with simple ingredients that would also protect my skin without breaking me out. This not only kept away the burning rash I get from the sun, but protected my husband and I from any sunburn at all. It worked not only in dry conditions, but it stayed on for hours after we swam in the ocean. We also liked the fact that it smelled herbal, almost like pizza/Italian seasoning. That didn't bother us because we both hate the smell of most sunscreens. If you have sensitive skin or are looking for a more natural product, I highly recommend this!

Great reef-safe, easy-to-apply sunscreen (comparison of three ThinkSport products)
Size: 6 Ounce (Pack of 1)
I will start by saying that I am used to traditional non-mineral sunscreens and tend to only buy physical/mineral-based sunscreens when I'm going to be in a tropical ocean and need something reef-safe, though more and more kids sunscreens are shifting to mineral-based. After quite a bit of research I settled on ThinkSport for my family's recent trip to Hawaii, and I'm very pleased with it. I brought and used three types of Thinksport sunscreen: Thinksport Kids lotion (yellow/orange and teal squeeze bottle), Thinksport adult lotion (Black, white, and orange squeeze bottle), and Thinksport adult spray (black, white and orange spray bottle). All protected us from sunburn and rubbed in to be invisible as long as skin was dry and free of visible hair (visible whiteness persisted around my husbands facial stubble and chest hair). The only difference between the kids lotion versus the adult lotion is scent--the kids version has a fruitier, more tropical but not-too-strong scent (possibly coconut and something else? it was hard to identify) that I found unobjectionable (though one if my kids wasn't a fan), and the adult lotion had a lighter, less sweet, more citrus-y scent (my son though maybe lime and mint, but I'm not sure that's accurate) that I LOVE. The adult spray had no discernible scent, so I suspect the kids spray might be fairly unscented as well. The easiest to apply by far was the spray--it sprays on white, but feels very light, rubs in easily, and becomes invisible quickly. I was a little worried about whether it could possibly be effective given how light and thin it felt, but it was! The lotions weren't thick for a lotion (but much thicker than the spray) and went on easily, but took more rubbing in to disappear than the spray (this is consistent with my experience with lotion vs spray in traditional sunscreens as well). Invisibility was harder to get after a second or third application or when skin was damp, but all-in-all I found all three Thinksport products to be superior to other mineral-based sunscreens I have tried in the past. In the future I'll probably buy the adult thinksport spray for my kids and husband (who all much prefer a spray-on sunscreen) and the adult thinksport lotion for myself (because I love the scent and don't mind rubbing it in).

Dependable sun protection for active days outdoors
Size: 6 Ounce (Pack of 1)
I like how this sunscreen provides reliable broad-spectrum protection and holds up well during outdoor activities. The zinc oxide formula gives me peace of mind, and I appreciate that it's water resistant and reef-safe. It applies smoothly for a mineral sunscreen and stays on effectively during sports, swimming, and long days in the sun. Overall, it's a trustworthy option for anyone looking for strong sun protection.

Clean product
Size: 3 Ounce (Pack of 1)
I only gave it 4 stars because of the smell. Of course it’s sunscreen so it’s going to have a chemical smell but this smell is just too strong for me. Other then that, it’s a great sunscreen. Does take some more rubbing in and be carful to rub it in really good or you’ll have white streaks all over your face. Leaves a bit of a white cast. You don’t need much.
