Filtrete Under-Sink Advanced Water Filtration System (3US-PS01)

The Filtrete under sink water filtration system is a professional water filtration system that can help reduce the level of sediments, odor, and chlorine taste of water. The water that comes out of the tap will be cleaner and taste better.


The system will maintain the typical water flow that you are used to from your sink. The unit is connected to the cold water supply in your kitchen sink. The installation process is fairly simple and the filters are quite easy to change when necessary. There are no tools needed to change the filters and no extra faucet is required.

Does it Filter Lead?

When the maximum version is purchased it will remove lead from the water as well. The system is designed to remove chlorine odors and taste, parasitic cysts, soil, silt, sand, sediment, and rust as well as other chemicals and minerals that may be found in the water supply. The filter will remove particulates to 0.45 microns, which is sufficient for removing most bacteria as well as all protozoa, for example cryptosporidium.

How Much Room is Needed to Mount the Filter

While the under sink water filter is not extremely large, it does take up a decent amount of room underneath your sink. You should not try to mount the filters at an angle as they may not work properly as a result. If you are struggling with room under your sink, you may want to contact the manufacturer in order to discuss alternative mounting options for the filters.

How to Test the Effectiveness of the Filter

The easiest way to test whether or not the filter is working is to compare the color, smell, and taste of the water from before the filter is installed to after the water is filtered. Hot water remains unfiltered so a comparison of the cold water with the hot water can be completed once you have installed the under sink water filter. There are also home water testing kits available that can be used for a more scientific testing of the water after it is filtered.
