How to Choose the Most Effective Water Filter for Your Refrigerator

It’s highly likely that when you go to get a new refrigerator, you’ll find at least one with a built-in water filter. In today’s world, the truth of dangerous chemicals in our water is demonstrated by the availability of pricey bottled water almost everywhere. As the demand for fresh, healthy water on the go has grown, so have the techniques to make filtered water more accessible. For more details click refrigerator water filter replacement.

There are numerous refrigerator water filters on the market today, but the quality of these filters has vastly improved in recent years. They all, for the most part, use GAC (Granular Activated Carbon). However, not all refrigerator filters are created equal. Because of the quality of the filter media and combination of the most successful technologies, the Aquasana AQ-7000 has earned the right to be dubbed the most effective in-line water filter on the market.

A GAC (Granular Activated Carbon) Filter of High Quality Is Required

The EPA considers a GAC carbon filter to be the best available technology for organic chemical removal since it can absorb a wide range of hazardous compounds. Micro pores occur when activated carbon is subjected to high temperatures. This newly developed surface is capable of filtering out a wide range of contaminants, including chlorine, pesticides, trihalomethanes (THMs), and other cancer-causing substances. GAC also eliminates unpleasant tastes and odours.

In a refrigerator water filter, there are three different technologies to look for. Mechanical filtering (down to 0.5 microns), adsorption (contaminants chemically attach to the surface of the GAC filter medium), and ion exchange are the three methods (replaces harmful lead ions with healthful potassium ions).

1. Filtration down to the sub-micron level
A highly porous surface should be present on a high-quality in-line refrigerator filter. A coconut shell carbon block is one of the more expensive and high-performing materials. The filter should be able to filter sub-micron particles down to 0.5 microns or fewer. This allows chlorine-resistant microscopic organisms like cryptosporidium and giardia to be effectively removed. Low-cost carbon is less effective and requires more frequent replacement. Choose a filter that will last for at least six months.

2. Assimilation
While sub-micron filtration works by physically blocking impurities, adsorption occurs when a carbon filter attracts a range of dissolved contaminants, which are then held or adsorbed on the carbon particles’ surface. A fridge water filter, unlike pitcher water filters like Brita, has a lot more carbon to go around. Because of the wide surface area, the water contact time is prolonged. As a result, increased adsorption of various substances is possible. Chlorine, lead, VOCs (Volatile Organic Chemicals), THMs, cysts, turbidity (sediment level), and most other tap water contaminants are filtered out using a highly compressed carbon media in filter systems like the AQ7000.

3. Ion Exchange Ion exchange is the final filtration technology. Lead is filtered out at this stage through a complicated ion exchange process that replaces lead ions with potassium ions. This method is particularly good at removing lead and heavy metals. It also improves the mineral balance of your water. One of the minerals that gives your water its natural spring water flavour and a neutral pH is potassium. To achieve this result, a coconut shell carbon block can be coated with potassium charged microporous zeolite.
