The SGF-G22 filter is a replacement for the Whirlpool 4396508 water filter. To keep your SGF-G22 refrigerator water filter properly functioning, you will need to replace it from time to time. This filter works to remove unwanted materials and particles from your water supply, so you never have to wonder what is in the glass of water you are drinking. When you replace your water filter routinely, you maintain fresh, crystal-clear water every time you dispense it. To do this, consider replacing your existing SGF-G22 water filter with a new one. It is easier to do than you may realize.
How the SGF-G22 filter process works
When in place, the SGF-G22 works to cleanse water as it comes in from your home’s supply and before it dispenses into your glass. The way it works is by using a scientifically engineered filtration method that removes impurities quickly. It works through the use of activated carbon. This is a form of carbon designed to be very porous. This occurs because it has an increased amount of surface area. This allows for the activated carbon to use the method of adsorption to remove particles. Adsorption allows gas, liquid and other dissolved solids to hold onto the carbon surface.
So, how does it work? When water comes into your refrigerator, it enters into the SGF-G22 filter chamber. Then, as it fills up with water, the filter is pushed through an internal chamber that contains the activated carbon material. It is there that anything in the water, such as lead, chlorine, cysts, bacteria, asbestos or other materials, is removed. These particles attach to the carbon while the water, now clean, washes through the filter and into your drinking glass.
Changing your SGF-G22 filter
To change your filter, there are basically two potential methods. The first step is to locate the existing SGF-G22 water filter, which may be at the interior top portion of the fridge, between the sliding doors, or on the door itself. Once you find the filter, you will need to follow either a push or pull method of removing the old water filter and replacing it with the new one.
A push-tab design will generally have a tab located at the very front of the filter housing. If this is the type you have, open the housing by pushing the tab. When you do, this will cause it to release a latch. Hold that latch and turn it counterclockwise. This causes the filter to pop out slightly and allows you to pull it out.
A secondary option is to locate the pull tab on the housing and pull it forward to release the same latch. In both cases, follow the same steps in reverse to insert the new SGF-G22 filter. Afterwards, run a gallon or more of water through the filter before consuming any water from your fridge.
It is often recommended by refrigerator manufacturers to change your filter on a regular basis. How frequently depends on your overall use, though you should do so at least one time every six months. If you notice the water is coming out slowly, this means the carbon has bulked and the filter needs to be replaced, check out Discount Filters for a large supply of filters for your home.
