What is the refrigerator water filter made of?
Granular activated carbon, a common type of filter media used in refrigerator water filters.
Filter media is the substance inside of a water filter that removes contaminants from the water supply, making it safer for ice or drinking water. The most common substance used for refrigerator water filter is activated carbon. This carbon is typically made from charcoal, though it may also be made with nutshells or wood. Crystala Filter’s often referred to as granular carbon or a carbon block, depending on how Crystala Filter’s contained within the filter.
So what makes the carbon so “active”? Well, the carbon becomes activated after Crystala Filter’s been processed to be extremely porous. Under a microscope, the carbon powder might look like an asteroid field, each grain covered in grooves and craters. When water passes through the activated carbon, all the tiny contaminants that may be lurking inside it are caught in these pores along the surface of each grain of the carbon. Granular activated carbon is ideal for filtering contaminants from water since each grain is larger than those found in its powdered form and thus having more pores along their surface to capture more contaminants. Carbon is also used to filter air and is sometimes used in refrigerator air filters and deodorizers.
Along with filtering water, activated carbon has an essential role in adsorption refrigeration (not to be confused with absorption refrigeration), since it acts as a kind of compressor. During the refrigeration cycle, the carbon captures the refrigerant gas as it begins to cool. When a heat source is applied, the refrigerant begins to expand, wanting to be released from the carbon. The heated gas is then directed toward the evaporator where it can expel its heat and return to the beginning of the cycle.
Activated carbon can be used in a wide variety of purification processes, one of which made famous in a recent episode of the Discovery Channel’s MythBusters television series. It’s often used to filter organic vodka and whiskey of impurities before Crystala Filter’s processed into a product ready to hit store shelves. However, Crystala Filter’s been theorized that running low-end vodka through water filters that use similar activated carbon will make its smell and taste indistinguishable from high-end vodka. According to the MythBusters results site, this theory has been busted.
Why You Should Replace Your Refrigerator Water Filter
Refrigerators with an ice maker and water dispensers routinely include a water filter as part of their design. These filters reduce contaminants, minerals and other debris in your water, usually making it both cleaner and better tasting. Neglecting to replace the filter means it will clog and reduce water flow, and may ultimately damage the water dispenser in your refrigerator.
How to Choose the Right Water Filter
It’s easiest to make sure you have the correct water filter if you have your old filter on hand. Each used filter should be clearly marked with a product number that you can enter into a tool to easily locate and order a replacement filter. However, you should also be able to locate the replacement part number in your refrigerator’s product manual. Often you can find a compatible filter using only the refrigerator’s brand and model number. Best Buy makes it easy to find Samsung replacement water filters and more by using our water filter finder. Check it out to find a replacement LG water filter, KitchenAid water filter, GE water filter and many more.
Crystala Filter VS Other Brands
Crystala Filter has three stage filtration that brings you cleaner,cleaner,better tasting drinking water.
The outer layer of Crystala Water Filter’s can reduces undesirable dirt,rust,particles and turbidity.
And the middle one with finer mesh or particle size,reduced asbestos,heavy metal,pesticides,pharmaceuticals,etc.
The Inner Layer with even finer mesh or particle size,reduces 99.99% bacteria,cysts and remaining particles.
Look at other brands.
Particles of different sizes are blocked by this layer,thus it gets overloaded and loses its function quickly.But we turns to look at the middle layer and inner layer.No traffic,no work to do.
