Pure water filters - the truth about potentially dangerous filter you can buy in stores

Pure water filters - the truth about potentially dangerous filter you can buy in stores

Water Filter

If you're like me, you probably do not trust your city's water supply and can not believe every claim of the companies that make wild water filters pure.

What we need is an overview of products on the market, and a better understanding of how the health, clean water can be brought into our homes and gave confidence to our children. Let me do for you.

From what I read, we can divide all the systems of pure water into two large groups: those who seek to make the water soShe also strips of pure natural minerals in it, and others who seek to filter out the smallest particles and organisms. Neither makes the water safe and healthy, as you might expect.

Let's first look at water filters to produce pure water demineralization.

And 'popular for pure filtered water to remove minerals, because the water is clean. It seems logical, there are some old science, backing up and his widely used in wastewater treatment plants large industrial. Many citiesWater Authority, for example, give to drink this water. But it is not healthy.

The easiest way to remove the minerals in the water is distilled to it.

Do you remember high school chemistry experiments, and the college where the water was boiled converted into gas, passed through a coil of glass and condensed back to water. The distillation.

While the final sample of distilled water looks clean and definitely does not contain bacteria, it still contains the chemical synthesisthat boil at a lower temperature than water and leaves behind the minerals, it absorbs all the water in the depths of the earth, as it creeps past the pristine rocks and small traces of dissolved minerals.

Why do you want to remove these trace elements with pure water filter?

And 'through our drinking water, to get the minerals such as calcium, magnesium and potassium in the body. Thank God, because we need them, and they are sick and unhealthy without it. The World HealthOrganization not completed long ago that "drinking water must contain a minimum amount of essential minerals." No water anywhere on earth is a natural mineral-free. There must be a reason. I think we can say that distilled water is used for a long period unhealthy, and pure water filters, which are made of strips of minerals are not recommended.

There is another common way to desalinate the water.

Putting them through a very thin membrane filters with a sophisticatedDeveloped method called reverse osmosis requires 40 or more years in the printing industry, the mineral-free water in some printing processes.

Reverse osmosis was popular in the Middle East after the first oil crisis of 1970, when the Arab states have money to spend on industrial-size desalination along its coasts, the deep desert, which could be irrigated, and a population that could accept less-than-healthy water for specific purposes. U-boats also installed a reverse osmosisUnits.

It works by forcing water through a thin membrane that blocks all the water molecules smaller.

And therein lies the first problem. The molecules of synthetic chemicals such as herbicides and pesticides are smaller than water molecules. So, running water in the so-called "pure". And the second big problem is that trace elements are stopped by the membrane filter. We have just seen that this is not good for us.

OtherCategory filtering systems for fresh water are the candles that we see in commercial advertising.

Block carbon and granular activated carbon filters are used in many water filters pure.

Among these active elements in free form, as a handful of sand. These pure water filters work by creating a process in which contaminated particles chemically or physically bond to the surface of the filter. In this way, the pollutants are absorbed into the filter or block them. Minerals willfrom. But, as the microscopic cysts, disease and suffering are to be transported.

A certain type of activated carbon such as carbon is the best available at the time, after the U.S. Environmental Protection Agency. But even this has its limits.

Then there are multi-media block filters clean water.

These are among the best. You use what you can do charcoal, and then cleaning company to the next level. These water filters are the pure material, the recording and stops alongImpurities, but the company in a form "candle" compressed. In addition, these extremely fine porous barriers filter unit, the water must be let through. This barrier stops the sediment and Cryptosporidium and Giardia cysts dangerous diseases of the stomach. With the active filter that prevents this type of system the effect of channeling granular filter, a portion of water is not actually physical contact with cleaning materials in the activeFilter.

So to summarize, pure water filters are divided into two groups. Those who take the healthy trace elements we need and where they can try to be blocked by synthetic chemicals, bacteria and viruses. In my opinion the second type is better if they stop components, all the harmful impurities, because our bodies can in trace elements from drinking they need to take.

How to select a portion of the water filter 7: dangerous pollutants

Select Part 7 of the way to the range of water filter, we are on volatile organic compounds (VOCs), heavy metals, arsenic and focus. We begin by considering the short-term VOC. Volatile refers to substances that vaporize or evaporate quickly. For example, auto gasoline contains many VOC and evaporates very quickly, which is why the smell of gas so easily. At the molecular level VOCs contain carbon, which is why as organic. They areNatural disasters and man-made and are sometimes found in almost everything. The U.S. Environmental Protection Agency (EPA) estimates that VOCs are present in one fifth of the nation's water supply. High on the harmful effects can be acute (immediately hazardous), while long-term impact with small chronic health problems in general can cause central nervous system. There are many substances that qualify as VOCs, but not all dangerous.Perhaps most frustrating is the lack of information on this topic. There is very little known many of the VOCs. Currently, EPA regulates the VOC most commonly found in water. The list includes benzene, 1,2-dichloropropane, dichloromethane, tetrachloroethene, carbon tetrachloride, 1,2-dichloroethane, vinyl chloride and trichlorethylene. Do not be overwhelmed by the scientific name. Although the fear sounding name, and do not want contact with one of them, are all but onequite easily from the water with granular activated carbon (GAC) filter to remove water. The hard part is vinyl chloride, which takes a ventilation system. In short, this is a single system, nozzles, water jets and combine with air used. This allows the vinyl chloride evaporates water. All this is accomplished in a tank that traps and removes harmful gases, average or with special openings to the outside safely. Eventually, the VOCs are terrible, but faireasily removed from the water.

Heavy metals are a bit 'more complicated, especially because there is little scientific consensus on what is known as Heavy Metal. It has been suggested that the term "toxic metals" better, not because the molecular weight of the metal, the main problem. Toxicity is the main problem.

Water Filter

Lead is the most common followed by toxic metals, often in water, the density of Mercury. Fortunately, the lead can be easily removed with standard sodiumTion based softening and / or granular activated carbon (GAC) filtration. Mercury in water, organic and inorganic, and each should be treated differently. Organic mercury is readily removed from the GAC, while inorganic mercury complex needs of a reverse osmosis filtration. This is usually done with a drinking water system, although whole house RO systems are available, but are much more expensive.

As a word of caution you should quit immediately, you mustRemove any contamination at home. This is a typical overreaction to every drop of water throughout the house has to think 100% free of contamination. Maybe in a perfect world, but many pollutants, but very bad if it is ingested, are fairly benign, if artificial respiration or absorbed through the skin, making drinking water and cooking, the main concern. Please do not miss the point, I wish everyone had the ultrapure water in their house, but compromises. SomeThe impurities are only at concentrations harmful dermal eight or ten thousand times higher than levels that are harmful through consumption.

more harmful trivalent arsenic and arsenic a bit 'less harmful than pentavalent arsenic is available in two variants found in water. Both are carcinogenic, but both are fairly easy to remove from water. For situations of drinking water, reverse osmosis systems with a (Thin Film Composite) membrane and reduced trivalent TFCpentavalent arsenic to 70-80% and 93-99% for applications throughout the home must first be oxidized trivalent arsenic in its pentavalent form. Although chlorination is the traditional method, there are other ways to oxidize the trivalent arsenic. Once oxidized pentavalent arsenic, can be shared with KDF / GAC water cartridges are removed. KDF is kinetic degradation fluxion GAC and activated carbon in granular form. These are the filters regularly, not difficult to find.

*** PleaseNote: It is important to remove pentavalent arsenic filter replacement schedule! It would be better to get in early rather than risk, such as replacing out and start dumping contaminants back into the water .***

With recent events in Japan, especially the radioactive nuclear disaster and subsequent editions devote part 8 of the road for the series of filter for the water with radioactive substances Select.
