How Often Should I Change My Refrigerator Water Filter?
If your refrigerator dispenses water, chances are it uses a water filter. And if it’s been a long time since you’ve replaced it, the inside of it may be clogged with some of the gunk. Changing your refrigerator water filter is the kind of routine maintenance that can be easily be ignored, but just like the oil in your car, it’s important to keep a regular schedule. Most manufacturer guidelines recommend that you replace your water filters every six months. Of course, these guidelines are just for broad situations – rather than your specific situation. If your family uses a heavier than average amount of water, your filter could expire…

Why Active Carbon Water Filter
Is Your Best Choice What’s activated carbon block water filter? How it works and how to choose among options for your specific needs? During water filtration, Activated carbon is often the media used to remove contaminants and impurities. Carbon is probably the most efficient absorbent known to man, and it is unique because of its thousand tiny pores that can absorb. The carbon is positively charged to attract negatively charged impurities such as chlorine, chemicals and volatile organic compounds (VOCs). Most carbon water filters are either made with granular activated carbon (GAC), or powdered block carbon material. Activated carbon water filters are rated by the size of contaminants they remove.…

Which type of GAC filter system do I need?
A filter with granular activated carbon (GAC) is a proven solution to remove certain chemicals (in particular organic chemicals) from water. There are commonly two types of GAC filter system, including a whole-house filter or a point of use filter. Each system has its own features and is used in different applications. Sounds confusing? Don’t worry. Here it’s a guide for to find out your Mr. Filter. There are several factors to consider: The type and amount of contaminants in the water, Other chemicals in the water, Water use, and Exposure pathways that need to be eliminated. For those who have no clue about exposure pathways, exposure pathways are the…

Water: Our Suffering Best Friend
I live along a lakeshore. For years, water has been my best companion. Its face changes moment to moment. Water is just a lady with a thousand faces. This spring, I saw a new face. In March, our neighbourhood experienced a very unpleasant smell and taste in the lake water. For days, its surface stayed still. Volvox algae was soon found out to be the source of problems. It is non-toxic, but meanwhile depletes lake oxygen as it dies off. The algae bloom tells us that our lake is processing a load of nutrients, which typically flow from human settlements. Our lake is a rural lake with forested park on…

Activated Carbon & Water Filters
Carbon is a substance that has a long history of being used to adsorb impurities and is perhaps the most powerful adsorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can adsorb literally thousands of different chemicals. Activated carbon is carbon that is electro-positively charge, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules. Activated carbon filters used for home water treatment typically contain either granular activated carbon (GAC) or powdered block carbon. Although both are effective,…

Beware of Bottled Water – Little thought for your health
In a hot summer day, I was in a supermarket trying to find some sparkling water to kill my thirst. Stopped in front of different brands of bottled water, I was confused. There were so many labels of pure springs and ice water that almost convinced me the liquid inside these bottles is the purest drink around. But then, a thought hit my mind: labels could be misleading, or sometimes deceptive. I remember in one case, water coming from a well located near a hazardous waste site was sold and labelled as “spring water.” I withdrew my hand from these bottles and decided to find out the best water solution.…
