Fridge Water Filter

The fridge water filter is a replaceable unit that purifies the water used by fridges to make ice cubes and cold water. It removes most the harmful impurities without removing beneficial elements, like fluoride. A filter makes the water taste and smell better, and is especially helpful in areas that have poor water quality. Even in areas with good water quality, maintenance work on pipes occurs regularly and this can introduce impurities into the water. Filters need to be replaced every six months but they are inexpensive and easy to change.

The filters have a cylindrical plastic canister that is sealed at one end and has openings at the other end. Some filters are long and slender while others are short and bulky. Some have two connectors while others have just the one. The single connector has one hole on top and another hole on the side. These holes allow water to enter and leave the filter from the same connector. A filter holder can be found either at the base or inside the refrigerator, and may have a cover that needs to be removed before the filter can be changed.

Inside the canister of a fridge water filter are several different layers that remove the various impurities. Micropore pads remove silt, dirt, sediment, rust and other undissolved particles. The pads also remove cysts that can cause severe illness, such as giardia and cryptosporidium. Outbreaks of these cysts in public water supplies occur from time to time and often result in people being hospitalized. The pads also remove microorganisms and other biological matter.

Another layer has granules of activated carbon that absorb chemicals dissolved in the water. The granules are very porous and have a high surface area which allows them to absorb a lot of chemicals. Some chemicals only make the water smell and taste strange but other pose a serious health risk. Very small amounts of chemicals such as chlorine, lead, mercury and pesticides can be found in most water supplies. Chemicals that have been linked to cancer, like benzene, can also be found.

Filters have an average life of about six months but this will vary depending on the amount and quality of water that flows through them. Once the filter starts to become saturated with impurities, the amount it can absorb from the water quickly drops. It is usually obvious when a filter is nearing the end of its life as the color and taste of the water starts to resemble that coming from the taps.

The procedure for removing the fridge water filter depends on what type it is. Some filters are ejected by pressing a button next to them, while other need to be unscrewed and pulled out. Always consult the fridge manual before attempting to remove the filter because the water and power supply may need to be turned off before the filter is changed. Some fridges have a light that indicates when the filter needs to be changed, and this may need to be reset by holding down a button for a few seconds.

Manufacturers recommend using certain brands of water filter but there are also generic brands available that are often cheaper. However, it pays to check that the generic filters are suitable for the fridge make and model as not all filters are compatible. Filters are not expensive and most have a retail price of around forty dollars. That works out to a very affordable cost of twenty cents per day for clean and tasteless water. The filters can be purchased individually or in triple packs that are slightly cheaper. Filters have no expiration date and can be stored for years before use.
