Everyone is looking for new ways to help improve their health. Whether you’re dieting, working out, or simply trying to increase your water intake, it’s requires dedicated effort with some parts easier than others.
When it comes to the water you’re drinking, are you confident that you’re ingesting lead-free, healthy, treated water? Can you count on the water you’re getting from your home?
It’s time to start thinking about how your water is filtered, regardless of whether you’re drinking water at home, out and about, or in any other location. If you live in America, water filtration and clean water probably isn’t the first thing on your mind when you head to the sink to fill up a cup.
You’re not living in a developing country, so your water has to be clean, right? Unfortunately, toxic tap water is a real issue in several different cities throughout the United States, including (but not limited to), Milwaukee, Wisconsin, Brady, Texas, and the well-publicized and infamous Flint, Michigan.
We’re going to lay out everything you need to know about the state of your water, water filtration, and the types of water filters that might be available to you, as well as the benefits of water filtration for you home and your family.
What Is a Water Filtering System?
If you’re unsure about what a water filtering system is to begin with, here are the basic. In its simplest form, a water filter helps decontaminate water by either using a physical barrier, chemical process, or a biological process.
People use water filter systems for a variety of different reasons, and there are dozens of benefits of filtering your own water. For example, people will use water filters to remove chlorine and bacterial contaminants to provide better tasting and better smelling drinking water. They’ll also use them to remove lead from drinking water immediately before they drink it, eliminating the chance of a harmful substance entering their bodies.
Another benefit of water filter systems is that they provide you with clean water without racking up a huge bill from plastic water bottles ( environmentally-speaking, this is a much better option too).
Overall, drinking clean, filtered water can help to protect your body from diseases and lead to greater overall health. Filtered water can reduce the risk of gastrointestinal disease by more than 33 percent, help children’s’ developing immune systems grow strong, act as the last line of defense against 2,100 known toxins from drinking water, and greatly reduce the risk of rectal cancer, colon cancer and bladder cancer by removing chlorine and chlorine byproducts.
And water filtration doesn’t only benefit drinking water. In fact, filtered water should be used for cooking, drinking, brushing teeth, bathing, and more. Using filtered water means there’s a healthy mineral deposit and a healthy pH in the water you ingest!
Types of Water Filters
There are several types of water filters that are typically used, each with different mechanics and functions, but all serving the same purpose: cleaning your water supply to provide healthy, safe water. Let’s focus on a few common types.
The activated carbon filter is one of the most common household water filters. This type of filter uses activated carbon granules that attract and trap chemical impurities through an absorption process.
Activated carbon granules are based on charcoal and are very porous forms of the carbon that is created by burning wood with a reduced supply of oxygen. Charcoal, somewhat like a cross between lead and a sponge, has an internal surface area that’s riddled with nooks and crannies that can help to boost that absorption process.
The Environmental Working Group does offer one important caveat to remember when using carbon filters:
Keep in mind that carbon filters vary greatly in effectiveness. Some just remove chlorine, and improve taste and odor. Others remove contaminants including asbestos, lead, mercury and volatile organic compounds, or VOCs. However, activated carbon doesn’t remove common inorganic pollutants such as arsenic, fluoride, hexavalent chromium, nitrate and perchlorate.
Additionally, this type of filter isn’t ideal for dealing with hardness like limescale heavy metals, nitrates, fluorine, microbes, and sodium.
Here’s a helpful overview of how activated carbon works:
You remember osmosis from science class, right? It’s when one things absorbs another. Reverse osmosis is the forcing of contaminated water through a membrane at pressure so that the water is able to pass through, but the contaminants in the water are left behind.
Essentially, you’re making the water go against its natural inclination, to force the comaninents out of a water supply. Unfiltered water is pumped in through a plastic membrane, clean water flows through the membrane at pressure, and that semipermeable filter or membrane will catch all the contaminants in said water.
Again, the Environmental Working Group offers a helpful note regarding reverse osmosis:
Also, consumers should be aware that reverse osmosis systems waste a lot of water – they typically use three to 20 times more water than they produce. For this reason, EWG recommends that they be used for drinking and cooking water only.
Ion Exchange filters are some of the best filters for softening water. They can take hard water and make it more digestible by removing limescale. In layman’s terms, these filters are designed to split apart atoms of contaminating substances to make ions, then, then traps those ions and releases less good ions.
These types of filters use zeolite beads that contain sodium ions. These beads, which act as filters, trap the incoming contaminants and replace them with sodium ions. Without that magnesium and calcium, your water is going to taste softer much more pleasant.
This is one of the simplest ways to purify water. While this is less of a type of filter and more of a way to filter water on your own without the use of a fancy device, distillation is still one of the best ways to filter or purify water.
Distillation involves boiling the water, but then taking things a step further to ensure purity. First, you boil water to make steam, much as you would boil it to kill the bacteria. Then you capture the steam and cool it back into water in a separate container. Because water boils at a much lower temperature than other contaminants (like toxic heavy metals), these will stay back as the steam separates and boils off, leaving you with clean water.
Regardless of where you live (home, on the road, or when you’re camping), it’s important to keep your water as clean and filtered as possible. Water filters are becoming more and more important in a world where every day health seems to be diminishing. Remember to change your water filter every 3 to 6 months, or sooner if you notice the water flow slowing down or your water color becoming darker.
You can easily pick up a water filter at your local grocery store or supply shop, and it doesn’t have to be fancy. Even a simple $30 home filter that you put on the end of your sink faucet will significantly help,. Ultimately, it’s important that you’re putting your health first, and keeping you water clean and filtered is a big step in that direction.
