APEK is a well-known manufacturer of water filtration systems and the WFS-1000 under sink filtration system is one of their most popular products. It has a decent price and broad possibilities, it’s easy to install and maintain and has high capacity. Filtration is pretty long-lasting.


The system is designed, engineered and assembled in the USA. It has a one-year satisfaction guarantee and lifetime support by a certified WQA water specialist based in CA.

The set includes a 10″ polypropylene sediment filter and 2×10″ extruded carbon block filters. At the first stage of filtration, the dust, rust and other major particles are removed from your water. Further, your water will be gotten rid of chlorine, tastes, odor, cloudiness, color, VOCs and other chemicals. At the last stage, you get the filter with the smallest micron rating.

The alkalinity and the mineral composition of the water will not be harmed. Which is for sure important for your health as alkalinity helps control the PH levels in your body.

Note that even though it can be used both with tap and well water, the system will not remove heavy metals such as lead and fluoride.
