Refrigerator Water Filter

Drinking clean and pure water is very vital for every household. Water filters have played an important role in ensuring that waters are rid of contaminants that pose danger to one’s health. With the growing awareness of the significance of hygienic drinking water, manufacturers have produced various types of water filters for every need and requirement. These days, one can find almost any type of water filter for different purposes that make it easier for homes to have fresh and safe water.

Among the many innovations of water filter is the refrigerator water filter. A refrigerator water filter may be of two types specifically designed for refrigerator use. Refrigerator water filters, depending on its type, can be simply set inside the refrigerator or directly installed into it. It is intended for the water that runs through the refrigerator, either fir the in-the-door water and ice dispenser or the automatic icemaker.

The refrigerator water filter is like the water filter installed on faucets. Water passing the refrigerator’s waterline that supplies the water for the dispenser or icemaker goes through the filter that is directly installed in the dispensing unit of the refrigerator. The filter removes metals and chemicals that can be present in the water source. The newer refrigerator models come ready with built-in water filters, but a refrigerator water filter can also be bought and installed for the majority of existing refrigerator dispensers.

Changing Refrigerator Water Filters

How long a refrigerator water filter will last, depends on the amount of impurities the water contains and degree of use of the filter. A rule of thumb for refrigerator water filter replacement should be according to the specified instructions of the manufacturer or at the least, every six months.

Carbon is a main substance utilized in water filtration processes as it has the potential of absorbing a lot of the contaminants found in water. Nearly all of the refrigerator water filters that meet “NSF/ANSI 42” certification standards utilize “granular activated carbon” or GAC to draw contaminants and chemicals accountable for odor and bad taste in water. However, these types of filters can’t rid the water of more health-threatening impurities.

The process through which water goes through “GAC filters” do not enough time for completing the absorption of the more dangerous contaminants. Different bacteria are trapped, formed and multiply, further contaminating the water being processed by these filters. Also, Carbon does not get rid of heavy metals like lead –they may trap some sediments and heavy metal, but permit others to go through the output water.

Thus, not being able to change water filters every six months permits the unabsorbed and trapped water contaminants, as well as newly developed bacteria to flood the filter. This will allow contaminant leaks into the processed water. This will result to having more impurities in the water that’s supposed to be clean after filter process.

On the other hand, the advancement of technology has led to developments of “more absorbent” carbon-based filters, the “solid carbon block filters”. The filters absorb more contaminants as it takes longer to filter through the blocks of carbon. This gives enough time for the filter to absorb the more dangerous water impurities. The carbon blocks allow restraining bacteria and heavy metals from the output water, but sulfides and nitrates aren’t filtered. Nonetheless, these filters are enough to meet “NSF/ANSI 53” certification standards.

A number of refrigerator water filters can include “fiber water filters”. The filters are constructed of “tightly wrapped” spun cellulose or rayon fibers, which traps lead, rust, and other sediments. However, these types of filters are best effective when they’re used in combination with other filter types.

Refrigerator water filter is one way of ensuring that the water you drink from your refrigerator dispenser or even the ice cubes you use are pure. After all, there’s nothing like a cold drink straight from the refrigerator that’s utterly safe and clean.
