Quality Water Filters 4 You Archive Page
Wednesday, October 31, 2012
Flooding is a natural disaster that can easily fill water that is ordinarily clean and safe with dangerous chemicals and organisms, and necessitate the use of water filters in areas that don't usually need them. If you're in a flood-prone area, such as living on flat ground near a major river like the Mississippi, or if the area where your home is located is struck periodically by hurricanes, it's a good idea to prepare ahead of time for water purification.

No matter how diligent the local sanitation department, all bets are off when a sheet of brown, opaque water spreads over the landscape. Flood waters flow into factories and wash chemicals out of storage vats, and cause sewage treatment plants and sewer pipes to disgorge their stored filth into the water. With a mix of industrial chemicals and human urine and feces mixed into the slurry of mud and debris they also carry, flood waters are extremely dangerous to drink.

Of course, the water from a flood also penetrates wells, water reservoirs, and so on in the local area. Even if you aren't directly affected by the flood, your water supply can still end up befouled if it's drawn from anywhere the flood waters can reach.

Drinking polluted water can make you violently sick, with vomiting and diarrhea making you more likely to dehydrate in the hot weather that often follows a hurricane. If you're trapped on your roof amid a muddy, brown sea of sluggish water, waiting for rescuers for several days, it is extremely useful to have a way to drink clean water rather than quaffing the semi-sewage “neat”.

Anyone who lives in a flood-prone area should store a good water filter and a supply of Chlorox or iodine tablets for water purification, as well as a spare canteen and some clean drinking containers that can be kept clear of the flood waters, too.

Gravity feed filters are the most viable means of supplying yourself with clean water after a disaster because they require no running water or electricity to work. One example – though certainly not the only one – are the famous Berkey filters, with two stainless steel chambers stacked one above the other and upright “candle” filter cartridges. Water is placed in the upper chamber and percolates through the cartridge in order to reach the lower chamber, purified.

While you could use a reverse osmosis filter, you will need a hand pump to force water through the membrane in the absence of water pressure. This represents something with moving parts, which can break and leave you with no way to cleanse water. When choosing water filters for flood emergencies, the simplest approach – a passive gravity feed system – is truly the best.

Though this filtration is enough to remove chemicals and most microbes, it's best to err on the side of caution and throw in an iodine tablet, too. Add a scoop for filling the filter and a spare container or two and you will have the water filter kit you need to weather a flood disaster safely.

Seychelle's water filter pitcher sets out to break through the limitations that this configuration usually impose, and largely succeeds at its mission. The pitcher is more versatile and useful than most filters made in this configuration, while offering water storage at the same time. The pitcher shape makes it easy to put this filter into the refrigerator when in civilized surroundings for a cool drink on a hot day, and also eases pouring of the water more than is typical in gravity feed filters.

The Seychelle water filter pitcher consists of two levels – the reservoir at the top, and the main pitcher space at the bottom. Water is put into the reservoir through a flip top opening, and up to half a gallon can be held at once. This water then percolates down through the filter cartridge into the main storage area of the pitcher. This area holds 1 gallon of water; it can fully filled by filling the top section twice in a row.

There is no limit to the amount of water that can be processed through the filter cartridge daily. Some pitcher filters can only be used once or twice daily, and then left so that the cartridge can “recover”, but the Seychelle model can be used continuously if desired.

Filtering capabilities of the Seychelle water filter pitcher

The Seychelle water filter pitcher naturally centers around the cartridge that connects the reservoir and the storage chamber. The purification system removes around 85% of fluoride, but is more effective with other substances, cleansing over 99% of heavy metals like chromium, mercury, or lead, clearing out dangerous volatile organic compounds like DDT, insecticides, pesticides, and herbicides, and improving the taste, appearance, and flavor of the water by removing all sand, sediment, and rust particles, plus other particulate matter.

150 gallons, or 300 half-gallon refills, is the maximum working capacity of each cartridge in this device. After that, the cartridge ought to be replaced to continue to offer fast and effective filtering. You will likely be able to tell when this point is being reached because of slowdown in the filtering of water, as the cartridge's spaces become clogged with sifted-out contaminants.

Three different kinds of filters are available for the Seychelle water filter pitcher – a regular filter that removes everything that the standard does except bacteria a standard filter that centers on removing bacteria plus everything the regular filter removes, and a radiological filter that handles water contaminated by the most hazardous substances known to man. The latter can remove all or over 99% of strontium, uranium, cesium 137, radioactive iodine 131, radon 222, and gross beta, so the filter is useful in a nuclear disaster area, too, such as near a melted-down reactor.

 Filter pitcher features

The Seychelle water filter pitcher is made out of plastic, but this is Food & Drug Administration (FDA) approved material that does not leach BPA into your drinking water. The capabilities and safety of the pitcher have been tested independently and found to comply fully with both EPA and NSF standards.

This purification device is designed specifically with travelers, RV users, campers, and boaters in mind. Since it can also handle microorganisms like E. coli, cryptosporidium, and Giardia, it can be used with mucky outdoor waters, though abundant sediment naturally reduces filter cartridge lifespan. It cannot be used to filter salt water, however.

The pistol grip features ergonomic finger ripples to give a secure grip, even while pouring when the pitcher is full (at which time it will weigh around 10 pounds, since water is heavy). The pitcher weighs 3.2 pounds empty, with the cartridge fitted. Fully assembled, the Seychelle water filter pitcher measures 12 ¼” by 13” by 6 ¾”.

Designed to provide robust portable water filtration to people away from their home for extended periods of time, this Seychelle product enables advanced filtering of water at many different remote locations. It is also made in the United States, which is a positive feature for those who want to support American industry with their purchase or who trust American quality.

Berkey water filters make a virtue of sturdy, highly efficient simplicity. Almost all of them are two chambered designs, made out of either stainless steel or plastic, with one chamber set above the other. The connection between the two chambers is through one or 4 cartridges screwed into holes in the upper chamber's floor. Water is poured in the top and gravity pulls it downward through the cartridge into the lower chamber, where is it found fresh and pure a little later.

Berkey filters come in a range of sizes, from the Go Berkey – which can purify one gallon of water per hour, and features a nesting setup that renders it super-compact for travel – to the Big Berkey, which, when configured correctly, cleans up to 7 gallons of H2O per hour. None of the filters require any tools for assembly, and can be quickly and fully disassembled for cleaning. All components can be separated out, and the cartridges can be rinsed carefully with water to prolong their useful life (which is already quite long).

The cartridges or “elements” of Berkey water filters achieve astonishing reductions in a laundry list of harmful substances, from heavy metals to viruses to radon. This is achieved partly by the very fact that gravity is the only motive force for the water.

Rather than water pressure from a faucet “shooting” the fluid past the filtration elements in a split second, the water processed by Berkey devices percolates through at a natural rate. This gives the micropore barriers and various filtering substances a longer time to strain out or otherwise capture the harmful things the water is carrying. Filtration is still fast, but it takes place at a measured pace that enables greater cleansing than, for example, in-line filters can provide.

                                                      Black Berkey elements

Certain models of Berkey water filters, including one variant of the Berkey Light, the Travel Berkey, the Big Berkey, and the Royal Berkey include the justly famous Black Berkey elements. “Elements” is a term that Berkey uses to describe the upright cartridges mounted inside the upper chamber of their filters, screwed into place with a butterfly nut or other type of hand-tightened nut. These cartridges are black in color, hence their name, and offer enhanced filtration.

The ordinary white cartridges formerly used in many Berkey water filters provided a high degree of filtration already (again, partly thanks to the gravity feed system, allowing water to move through at a more leisurely pace and thus deposit more of its contaminants in the filter). The Black Berkey carries this a long step further, however, with results that place these filters at the cutting edge of success when it comes to small-scale or home water purification.

Black Berkey elements work by moving the water through extremely fine, complex channels; all the time the water is moving along these channels it is exposed to media that capture harmful substances in a wide range of ways. This has the effect of removing practically 100% of volatile organic compounds such as chlorine, benzene, xylene, and so on; cutting heavy metals to 5% of their pre-filtration levels; more than 99% of viruses, bacteria, cysts, and parasites, reducing them all to harmless levels; and practically all radon 222 and poisonous chemicals, leaving the water completely pure and safe to drink.Needless to say, particles, rust, odors, and colors are also removed from the water.

Rapid rates of filtration are achieved in Berkey water filters, despite the slow speed at which the water seeps through the twisted, microscopic channels of the cartridge interiors, by putting multiple elements into each filter. The smallest model has only one cartridge; most have two; and the largest have two mounted, with the option to mount two more for a total of four. The number of gallons per minute that the filters can produce will range from slightly more than 1 up to 7.

       Berkey's emergency utility

Emergency situations are another place where Berkey water filters shine. They can process water that is practically thin mud and extract clean, fresh, clear water from it. And they can be used without power – a boon in an emergency, and a benefit to your electric bill in normal times.

Are You Looking For Clean Water From Every Outlet in Your Home?

A whole house water filter helps improve water quality at all points in your home. You can have fewer fixtures and buildup on water pipes with the use of this filter. All water dispensing outlets including toilets and showers will give you clean water at all times.

The filter will be connected to your main water line to make sure that all impurities are kept out using one solution. You will then have cleaner water coming out of every tap in your home at all times.

What type of home water filter will work the best for you? You can have a good look over the common water problems faced by customers to decide the one that will work best you.  The water entering your home may contain bacteria, chemicals, sediments, salts and chlorine which may make water look, taste or smell bad. Adding a filter system to every outlet can be a daunting task but a whole house filter makes this simple and easy.

Let A Whole House Water Filter Address All Your Needs!

Typically, water contaminants that are a bit of an extra concern include chemicals and agents that cause hardness. These can be quite a nuisance especially when hardness concentration is on a higher side.  How can you know this? Your soap consumption will be high as it will not lather well. Even after you clean your tubs and sinks thoroughly, you will still notice white stains left behind. Your laundry may feel stiff or show white streaks after subsequent exposure to hard water.

The troubles don’t end here. Your water heaters will probably suffer the most if they are continuously exposed to hard water. High concentrations of chemicals and salts that cause hardness will ultimately result in the buildup of scales or hard deposits. Your water pipes may have reduced flow which can add to your worries. Hard water is mainly due to calcium and magnesium salts dissolved in water. You can easily get rid of these troubles by using a whole house saltless water conditioner. It helps remove calcium and magnesium salts effectively which are mainly responsible for causing hardness.

With the use of a whole house saltless water conditioner, you can have softer clothes and softer skin. You will also have reduced stains on your tubs and sinks. This water filter can also prolong the life of water pipes by reducing corrosion and scale buildup.

Water pipes made of copper are particularly susceptible to corrosion if water contains iron. Iron, as you are familiar, reacts readily with oxygen to form a reddish brown deposit (ferric oxide) also known as rust. If your water is high in iron content, you will observe reddish brown stains in your toilets and sinks. Your dishwasher will also show similar signs.

High iron content may lead to the yellowing of your laundry especially if you use chlorine bleach. You may also feel a metallic taste every time you drink water. The easiest way to know whether or not water in your home contains high iron content is by observing the sediments left after water is allowed to stand for long. A whole house iron water filter is a good option to be used in these cases. You will be relieved from this annoying problem as the filter will keep away iron from entering your water for good.

You will also be able to keep away heavy metals that are a potential hazard to your family’s health. The water flowing through the home water filter is cleared of mercury, lead, copper, nickel, chromium and cadmium. The result you obtain is pure water free from metal traces and other dissolved impurities.

Some water impurities can be extremely hazardous to your health. Frequent stomach upsets, intestinal disturbances, unpleasant odor and odd taste of water may point towards contamination due to runoffs. Your water does need to travel a lot before reaching you and may get contaminated during the process. Getting the right water filter installed will give you protection against all possible sources of contamination.

The rotten egg like odor from both cold and hot water pipes indicates sulfur bacteria or presence of hydrogen sulfide. Your water pipes may show signs of turning black and release black particles in the water. A whole house hydrogen sulfide/iron water filter can be utilized as an appropriate treatment to ensure none of the contaminants interfere with quality and purity of water from every tap at your home.

If you wish to have clear and contamination free water in your home for many years to come, trying a whole house water filter will definitely be worth it.
