  • Under the Sink Filtration Installation Diagram
Friday, July 29, 2016


The under the sink filtration unit is the most commonly used water treatment system to remove bad taste, odour, lead, and chlorine from a chlorinated water source (ie: city water from your municipality).

The first step to this filtration system is a sediment filter. The sediment filter is designed to remove suspended solids (sediment, turbidity or particulates). The filter acts as a net that catches unwanted particles in your water as it flows through the system. Only sediment will be trapped where traces of pathogen elements, heavy metals, and volatile organic compounds can still remain in your water.

The second step is a lead/chloramine reduction filter, also known as a carbon filter. The carbon filter will remove left over sediment, but also chlorine, volatile organic compounds, odours and unpleasant taste from water. As the water passes through the carbon filter, impurities like volatile organic compounds and heavy metals become chemically bonded to the carbon. The impurities will stick to the carbon bonding sites and water will leave the filter clean and safe for consumption.

The sediment filters must be replaced every 4 to 6 months and carbon filters must be replaced every 6 to 8 months depending on the water flow. Over time as the filters get used, they will become clogged making it difficult for water to pass through. You can replace the filter sooner if you notice the water flow is slowing down or the water colour becomes darker. We recommend marking your calendar to make it easier when remembering to change the filter.
