Let’s get started!
APEC WFS-1000 Under-Sink Water Filter Overview
The APEC WFS-1000 Under-Sink Water Filter is a point-of-use (POU) which means that it is installed in a specific household division to filter the water there, and not to filter the water in the entire household.
Another important characteristic of this water filter is that it is a conventional under-sink water filter and not a simple under-sink water filter. The APEC WFS-100 is connected to the cold water pipe and the filtered water flows through a specific faucet that needs to be installed as part of the installation process.
This system filters the water through a 3-stage filtration process which is good to remove the most common contaminants found in municipal water such as chlorine, sediments, chemicals, VOCs, bad taste & odors.
The system comes with long-lasting filters that last twice the competition, which is a nice plus.
Another good feature of this system is the quality of the faucet that is included, which is a 100% lead-free well-designed faucet.
And the manufacturer offers a 2-year extended warranty which should assure you that APEC trusts the quality of its product.
APEC WFS-1000 Under-Sink Water Filter Filtration Capabilities
The APEC WFS-1000 Under-Sink Water Filter is a good option for city water as it can remove some of the common contaminants found in this type of water, such as sediments, dust, chlorine, chemicals, VOCs, bad taste & odors, etc.
Is important to notice that while it filters out these contaminants, it won’t reduce TDS (so not suited for well water) and won’t remove minerals like calcium and magnesium that are beneficial for you and your family.
This device filters out contaminants from your water using a 3-stage filtration process:
- 1st stage: 10’’ high-capacity polypropylene sediment filter, that removes larger particles like sediments, dust, and rust
- 2nd stage: 10’’ premium high-capacity extruded carbon filter, which removes chlorine, chemicals, VOCs, cloudiness, and bad taste & odors
- 3rd stage: another 10’’ premium high-capacity extruded carbon filter, that ensures that all the contaminants mentioned before are filtered out, to improve the water quality and taste

You can also opt to use other filter cartridges in the 3rd stage to filter out specific water contaminants impacting your household water:
- a specific fluoride filter to remove excessive fluoride from your water
- a specific chloramine filter to reduce water impacted by this contaminant
Apart from the contaminants mentioned above, that can be removed with specific filters, it is important to know that this under-sink water filter isn’t suited to remove microbes and heavy metals.
