Why so much noise about water filters? Everyone has a water filter installed in their homes now right? Have you ever asked yourself if this stuff is safe enough to be used by you and your family?

Millions of people, perhaps including you, make do with public water for most of their house chores including for drinking purposes.


How safe is public water

 A recent study by the National Resources Defense Council (NRDC) shows that although public water may test fine at the source, it picks up a lot of contaminants on the way to your house. This results due to the combination of pollution and deteriorating equipment and pipes. These contaminants include arsenic, fecal waste, lead and chemical by-products.

Any alternative?

Perhaps, you consider yourself not at risk of all these because you drink bottled water. Unluckily, you aren’t. In fact, bottled water marketing campaigns have been so successful in shaming tap water (public water) and making people suspicious about its credibility that their sales went up 700 percent between 1997 and 2005. Skyrocketed with it, however, was the environmental degradations, landfill waste, human right abuse and a whole lot of other disadvantages associated with drinking bottled water.

What else?

I bring to you a much better option- water filters. Using either a physical barrier or observing a chemical process, a water filter removes impurities and lowers contamination of water, bringing you superb water quality that you wouldn’t have gotten without it.  

In a bid to fully grasp how safe water filters really are, we should learn the types of the filtration system and what contaminants they eliminate from our water system:

Activated Carbon

Charcoal is like a cross between graphite ‘lead’ in a pencil and a sponge. Through a process called absorption, charcoal attracts and traps chemical impurities. Basically, absorption involves the process where solid or liquid trap other gases or liquid. Water being liquid easily gives up these contaminants which are later on trapped. Do not underestimate charcoal with its large surface area, packed with several nooks and crannies. Charcoal is specifically good for removing chlorine-based impurities and chemicals introduced during waste-water purification, by some pesticides, and by industrial solvents. However, it can’t cope with limestone heavy metals and hardness. Although this a disadvantage, the probability of finding these metals in public water is low. Looking at the cost, you might need to do some replacing over time because the filter often clogs up at times. But, with this filter, be sure of drinking “clean” water.

Reverse osmosis

This method is quite easy to understand. A reverse osmosis process doesn’t use charcoal. It uses the simple act of pressure. Unfiltered water is forced to go through a membrane (effectively, a fine filter) at pressure, so the water gushes through, leaving the contaminants behind. A reason this might be better than the previously stated method is its ability to effectively remove heavy metal contaminants from your drinking water. still having problems understanding? Read this.


You might want to look at this from the “boiling” perspective. One of the simplest ways to purify water is boiling it. but, distillation goes a step further than ordinary boiling: you boil to make the steam, the capture the steam in a separate container leaving it to condense back to liquid. Since water boils at a lower temperature than most contaminants, the contaminants are left behind.

Wrapping Up

Truly, water filters have more effective ways of giving you access to clean, affordable water at your convenience even better than bottled water. Opt for one.
