Quality Water Filters 4 You Posting Page
Tuesday, April 9, 2013
Even at their most polite, kidney stones are unwelcome guests, causing assorted aches and pains and requiring expensive treatments to remove them. Though there are many causes for kidney stones, one possible source of these nasty little renal maces is excessive mineral and sediment content in your water. Minerals in solution can accumulate into stones in your kidneys when these perform their natural role of filtration – which is why a good reverse osmosis water filter can be useful in areas with high mineral content in the drinking water supply.
Drinking ample water (though not enough to cause you to float away) is one of the key methods of preventing kidney stones, and of keeping them from growing if you already have them. However, if you have hard water, it can raise the risk of stones calcifying in your kidneys, and is especially likely to cause recurrence of stones after they've been removed if surgical removal is necessary.
“Hard water” is water with a high mineral content. This mineral “contamination” occurs naturally in certain regions and can only be avoided by living where softer water is present. However, a good reverse osmosis filter removes approximately 90% to 95% of minerals, enough to greatly soften the water and remove any risk that drinking liquids will cause kidney stones.
Reverse osmosis water filters operate on a simple principle, although plenty of science and technology goes into designing them correctly. Most reverse osmosis filters require water pressure to operate – that is, they must be hooked up to a home's water pipes, rather than operating by gravity feed. The water pressure forces the fluid through a membrane that allows only water to pass while blocking most dissolved salts, minerals, and other contaminants.
Only cold water can be filtered properly by reverse osmosis, so the filter is hooked into the cold water supply running to a sink. The filter features a storage tank, often of several gallons capacity, and a drain line that connects to the drain pipe that draws grey water away from the sink basin. Not all of the water is forced through the membrane – a fraction of it is sent out the drain line to flush the blocked contaminants away.
Reverse osmosis water filters are “serious” water filters, since they are installed directly into the water piping system running to your kitchen sink. However, their filtration of contaminants in solution is second to none for those who need to get excessive mineral loads out of their water – such as those who want to keep their kidney stones from returning for a second act.
