Why You Need a Water Filter (And What Kind I Think You Should Get)

I don’t like water. Never have. It’s bland and it’s flavorless. Its biggest crime is that it doesn’t taste like coffee.

I have lived in a state of extreme dehydration for years now. But recently, I’ve been on a mission to remedy that. The ultimate reason I’ve been reforming my wicked waterless ways is because of my daughter. I want to be healthier for her, so as she grows up I can offer her the best in word, example and deed. I can’t exactly push her water intake as a child while never taking a sip myself, can I? (I mean, I guess I can, but I’d prefer to avoid the douche-bag do-as-I-say-not-as-I-do parenting style.)

The second reason I’m pushing my water intake is because of my struggle with extremely dry skin and cracked heels. That is such a huge topic all on its own that I plan to follow up this blog post with more info on that particular issue later.

So moving on to my quest for more water! In looking up how best to hydrate myself, I stumbled upon this lovely little tidbit of information:

Pensacola has the absolute worst drinking water in the entire United States of America.

In a nationwide study of the safety of tap water in major cities, the Pensacola water supply was found to have 21 chemicals that exceeded health guidelines, including radium, lead, bezene and carbon tetrachloride.

After learning this information, I spent the rest of the week researching water filtration options and ordering the best water filter method for my home. I was in such a hurry to get my water filters, I even signed up for Amazon Prime for the two day shipping. Think I’m overreacting? (Probably.) But check out the full list of contaminants found in Pensacola’s water supply:

Barium (total), Chromium (total), Cyanide, Mercury (total inorganic), Nitrate, Nitrite, Selenium (total), Trichlorofluoromethane, 1,2,4-Trichlorobenzene, cis-1,2-Dichloroethylene, 2,2-Dichloropropane, Monochloroacetic acid, Dibromoacetic acid, Chloroform, Xylenes (total), p-Dichlorobenzene, 1,1-Dichloroethylene, 1,1-Dichloroethane, 1,1,1,2-Tetrachloroethane, Monochlorobenzene (Chlorobenzene), Toluene, Ethylbenzene, Alpha particle activity (incl. radon & uranium), Combined Uranium (pCi/L), Cadmium (total), Lead (total), Di(2-ethylhexyl) phthalate, Heptachlor epoxide, MTBE, Total haloacetic acids (HAAs), 1,2-Dibromo-3-chloropropane (DBCP), Bromoform, Bromodichloromethane, Dibromochloromethane, Total trihalomethanes (TTHMs), 1,2-Dichloroethane, Carbon tetrachloride, 1,2-Dichloropropane, Trichloroethylene, 1,1,2-Trichloroethane, Tetrachloroethylene, Benzene, Alpha particle activity (excl radon and uranium), Radium-226, Radium-228.

OMGWTF?!?!??!?! I can’t even pronounce half the crap on that list, and I stopped Google searching what each one was and why drinking it is bad half way through the list because I was getting all twitchy. And this isn’t even the worst of it.

Most people don’t realize that federal law does not require tap water to be safe for long-term consumption. Only 91 contaminants are regulated by the Safe Drinking Water Act, yet more than 60,000 harmful chemicals are found in drinking water in the United States.

Why is this allowed? Because the long-term risks of cancer and other health threats are balanced against the cost and feasibility of purification by each city. The current mindset is that the contaminants are fully disclosed to the public, therefore if you care about your long term health, you will take steps to filter your water to your liking. Your water does not have to be healthy. And in Pensacola’s case, it is decidedly not so. You can check out your local drinking water quality by visiting the EPA website here.

So! Are you convinced you need a water filter? Since I’ve spent more hours than I care to admit researching the different options when it comes to water filters, let me share my findings with you. Here’s a simple guide to the most popular methods of water filtration and why I think all but one method sucks:

Distilled Water

How It Works – This process passes water over a heated coil‚ causing the water to vaporize and become gaseous. The steam then rises and transfers to a cooling chamber‚ where it condenses back into a liquid. This process separates water from inorganic compounds like lead‚ calcium‚ magnesium‚ etc. and destroys bacteria.

Why I Think It Sucks – This process does not remove most organic chemicals, since they typically vaporize at a lower temperature than water and are transferred over with the steam. FAIL.

Reverse Osmosis

How It Works – This is a process that exposes water under pressure‚ to a semi-permeable membrane with a very fine pore structure. Because most inorganic contaminants are of a larger molecular size than water‚ the membrane rejects certain contaminants‚ minerals and a large part of the water.

Why I Think It Sucks – Because many synthetic chemicals like herbicides and pesticides are smaller molecularly than water, they slip through. FAIL.

Granular Carbon Filters

This is the most popular home filtration method. (It’s what is used in Brita filters.) Granular carbon filters remove contaminants by adsorption‚ which is the chemical or physical bond of a contaminant to the surface of the filter. Activated carbon bonds to thousands of chemicals, in fact it bonds to almost all known chemicals! Water runs around the carbon granules, and the bad joo joo in the water sticks to the surface of the granules.

Why I Think It Sucks – This type of filter does NOTHING for straining out bacteria. They are worthless in terms of virus and protozoa, which aren’t adsorbed by the granules and just continue on their merry way through the filter and straight into your mouth. Yum yum! Plus, many chemicals that WOULD be adsorbed by the granules can make their way through the filter without being adsopbed if not exposed long enough. DOUBLE FAIL.

Carbon Block Filters (What I Recommend You Use)

How It Works – A carbon block filter is made of the exact same stuff a granular carbon filter is made up of… only it’s in solid block form.

Why I Think It Rocks – It works with the same method of chemical bonding through adsorption, but it has the added element of mechanical straining.

When water is pushed through the solid carbon block, it is FORCED to slow down and increase the contact time with the carbon, allowing the carbon bonding to take place to remove the chemical pollutants like toxins, pesticides, trihalomethanes, chlorine, bad tastes, odors, etc.

And whatever is missed by adsorption – like bacteria and protozoa and heavy metals like lead – are then strained out by the pore size of the block. Basically, it’s like trying to put a basketball through a hole the size of a ping pong ball. The pores in the block of carbon can filter particles down to sub-micron size. That filters dirt, sediment, rust, algae, bacteria, microscopic worms, cryptosporidium and asbestos. And because of the density of the solid carbon block, there is no room for bacteria to grow so this type of filter does not become an incubator for them.

This type of filter is so hardcore, they’re known as survivalist filters. They are what wilderness backpackers use to purify bacteria infested waters on trails. For added safety, you can put a couple drops of chlorine or bleach in your water to kill off bacteria gathered in a stream, and then it run it through the filter. The filter then removes the chlorine and bleach and dead bacteria and your bacteria infested spring water is now safer and tastier than your Pensacola tap water. Uhhh, WIN.

Best part is? They are super affordable! Since Jonathan and I are going to be moving around quite a bit in the future, we can’t really invest in a whole home filtration system. So instead, we’ve purchased a pitcher style carbon block filter (made with BPA free plastic!) for less than $25 and a sports water bottle carbon block filter for less than $20. So far, we are extremely happy with our purchases and will be using our bottles on upcoming camping and hiking excursions!

Do you use a water filtration system? If so, what kind do you use and why? Talk me people, my blog is so much more fun when the empty void I send this drivel into talks back. 😉
