Quality Water Filters 4 You Posting Page
Wednesday, November 21, 2012
In the midst of our hygienic modern lives, it's often easy to forget that the organisms that caused the pestilence of past centuries are still alive and well – it's only a good water filter, better-constructed pipes, or chlorination, which guards us from the same afflictions that troubled and sometimes killed our ancestors. One invisible menace that water filters can help deal with is Giardia, a microscopic protozoan parasite that infests the intestines.

Giardia is a tiny, bug-like organism that moves by swimming with the help of several minute tentacles. These protozoans can be found in any water that has been tinged with infected sewage or animal droppings. Once in your body, they cause diarrhea, bloating, and possibly dehydration. If untreated, you'll eventually recover, perhaps in a month, perhaps in year. However, you will then carry the parasites like a strike force of miniscule commandos that can infect others.

The parasite is fairly successful thanks to the fact that it can exist outside a host for a long time as an inert cyst. This is basically a “parasite in a box” – once it's inside a potential host, the Giardia pops out, attaches to the inside of the intestine, and starts multiplying.

Though there's more Giardia in poor countries where sewer lines aren't well maintained and a lot of people have little access to doctors, the protozoan lurks just about everywhere. That includes the posh neighborhoods of the United States as well as shantytowns – there's nowhere, in short, where taking precautions against these microscopic villains isn't a good idea.

You can boil water to kill Giardia cysts, but this is expensive and time-consuming. You can save a lot of money on electric bills – and help save the planet with a greener solution – by using a filter instead of boiling water to deal with the possible presence of these parasites.

Not every filter is created equally when it comes to protecting against Giardia. The protozoans will pass like greased lightning through shower filters, for example. A lot of regular water filters also have pores too big to catch the cysts. Ideally, you should find a water filter that is specifically labeled as being able to handle Giardia cysts.

Failing this, though, you can identify water filters that remove Giardia in several different ways. Those whose pores are 1 micron or smaller can catch the tiny cysts. Reverse osmosis filters keep Giardia out of the finished, purified water, and anything that has NSF Standard 53 Certification Giardia-proofs your drinking water supply.

If there is even the slightest chance of cysts infecting your water, using a water filter capable of removing them is a wise and prudent step towards protecting yourself and your family from much unpleasantness. Fortunately, such filters are readily available today and are usually multifunctional enough to deal with many other waterborne threats at the same time.  These filters can attach right to the faucet, can be installed beneath the sink, or be placed right on the countertop.
