Why Should You change Your Refrigerator Water Filter Every Six Months?

The life of refrigerator water filters is dependent upon the volume of contaminants in the water as well as the amount of use of the filter. Well water is more likely to comprise contaminants not found in publicly treated water and may need more frequent filter changes. As a rule of thumb, the filter should be changed as specified by the builder or at least every six months.

Carbon is the primary substance used in water filtration methods because carbon has the potential to suck in many of the chemicals found in water. Most refrigerator water filters, which meet Nsf/Ansi 42 certification standards, use granular activated carbon (Gac) to attract chemicals and impurities responsible for bad taste and odor, such as those that are a by-product of chlorine. These filters are not capable, however, to rid water of more dangerous, health-threatening contaminants. The recipe by which water is channeled straight through Gac filters does not allow sufficient time to complete the absorption of such substances. Various bacteria are formed, trapped and allowed to multiply, which supplementary contaminates water processed by the filters. Carbon is not capable to suck in heavy metals, such as lead. Gac filters may trap some heavy metals and sediments, but allow others to filter straight through to the production water. Failure to convert the water filter, every six months, allows unabsorbed water contaminants and newly formed bacteria to saturate the filter, forcing the filter to leak contaminants back into processed water. The water production may comprise more contaminants than the filter was intended to take off in the first place.

Technology has lead to the development of more absorbent carbon-based filters, solid carbon block filters. These filters comprise solid blocks of carbon to suck in contaminants from water. Water takes longer to strain straight through carbon blocks than it does carbon granules, so that carbon blocks contribute sufficient time for the absorption of more health-threatening containments. While carbon block filters are capable to suck in toxics, pesticides, Tthm's and other contaminants, they cannot suck in heavy metals or contaminants that are by-products of agricultural fertilization, such as nitrates or sulfides. The blend of carbon blocks allows them to restrain heavy metals and bacteria away from production water, however, nitrates and sulfides are not filtered. Even so, carbon block filters are sufficient to meet Nsf/Ansi 53 certification standards. Failure to convert carbon block filters, every six months, allows contaminants to saturate the filter, forcing the filter to leak contaminants into the processed water. When sediments are not removed from water, those sediments buildup and corrode filter fittings and water fixtures, causing them to leak. This type of damage to filters and fixtures may cause the production water to comprise more contaminants than the water input to the filter. Failure to convert the filters might also sell out the water pressure, within the filtering system, forcing it to be ineffective.

Some refrigerator water filters may comprise fiber water filters. These filters are made of tightly wrapped fibers of rayon or spun cellulose, which trap rust, lead and other sediments found in water. When used alone, these filters are ineffective in reducing any chemical or health-threatening contaminants. Fiber filters are best powerful for use with other types of filters to sell out the attention of sediments. They should be replaced, every six months, to avoid a build-up of sediments that would force the filter to leak the contaminants back into the processed water.

Buying a Used market Refrigerator? What Should You Look Out For?

As with any used product, used refrigerators should be considered inspected before they are purchased, in order to prevent getting a cooler that may have a preexisting problem. Even though there is no way to know what the compressor looks like on the inside, there are some indicators to pay attentiveness to on the outside. This is to avoid spoiling the great price you may have gotten on the unit by spending a huge number on repairs.

There are three things that are the most foremost to seek when seeing at a used refrigeration unit. These are the evaporator, the cabinet, and the condenser.

Evaporator Check

The evaporator is the box inside the refrigerator that contains a fan. All its parts should be secure and straight. Check the drainage by pouring water into the drain pan.

The fans should be running and not development any unusual noises. The blades should all look the same and be nick-free.

An evaporator qoute can also cause compressor failure. A exchange evaporator costs approximately as much as a new compressor.

Cabinet Check

Don't forget to check the cabinet. If it looks old and worn out, it's time to find an additional one unit. Be sure the door shuts tightly. Make sure the lights turn off when you close the doors. The gaskets should be checked to make sure they are not loose, split, or too dry. Be sure there aren't cracks. Problems with any of these things can lead to compressor failure later on.

Condenser Check

The condenser is the part on the outside of the refrigerator that has the compressor and fan on it. The compressor is black and has a large and a small tube arrival from it. With the refrigerator turned off, you should be able to slightly rock the compressor back and forth. If it doesn't rock, the shipping bolts were probably never loosened and the compressor will most likely be damaged.

Inspect the fan blades and the cowl colse to the fan for dirt. A unit that has been run constantly with a dirty condenser most likely has a damaged compressor. Check the condenser fins as well. Grease can cause damage by overheating and overworking the compressor.

If all things looks okay, you may have ruled out many potentially costly problems, although there is no guarantee. By inspecting the machine, you have greatly reduced your risk, but it is impossible to eliminate it all together. So stay diligent and be a smart consumer. Good luck buying a used refrigerator.
