On Water filters

[Guest guest]

Water filters are not all the same There is some controversy on the subject of whether or not you need a water filter. In Hawaii, they are blessed to have water that is exceptionally clean at the source. By the time it reaches your faucet, however, chlorine has been added—as well as potential contaminants from the pipes that it runs through. The chlorine, which is added to kill bacteria, can pose a health risk if it reacts with organic matter such as soil, fertilizer, or plant materials. According to the Environmental Working Group, “a compelling body of scientific evidence—nearly 30 peer-reviewed epidemiological studies—links chlorinated by-products to increased risks of cancer.” Here are three of

the most common types of water filters that you are likely to find on the market, and a few of their pros and cons: Activated carbon filters are granulated carbon filters that remove chlorine, parasites, viruses, and organic chemicals from your water. Unfortunately, they have two down sides: first, they are not the best when it comes to removing heavy metals and all microorganisms. Second, bacteria collected by these filters can actually be dumped back into the water that you’ve filtered. I generally don’t recommend this type of filter. Solid carbon block filters are better than activated carbon filters because they are less likely to allow bacteria to thrive in their filtering systems. They trap everything that activated carbon filters do, while also trapping more organic pollutants and chemicals.

However, it is important to change the filters twice a year, or when they are no longer able to filter water efficiently. Reverse Osmosis filters are the most effective for purifying your water, because they have three filtering mechanisms: a sedimentation filter, a reverse osmosis filter, and a carbon filter. These systems remove everything that solid carbon block filters do, along with 100 percent of the organic material, but they remove all beneficial minerals as well. Reverse osmosis filters are energy efficient, but not water efficient; they can waste about two to three gallons of water a day. They may require a plumber to install, and their filtering membranes should be replaced every year. Some water filtering systems are countertop units, while others can be stored under your sink.

Many types of filtering systems can be attached to your sink faucet. Suzi List Owner health/ http://360./suziesgoats What is a weed? A plant whose virtues have not yet been
