Woder WD-S-8K-DC Under Sink Water Filter Reviews

The Woder WD-S-8K-DC, just like the CuZn-200 above is a really popular under sink water filter and this is mainly due to its simplicity and effective filtration ability.

The other thing that makes it very attractive to many is the large capacity it has, in fact, it’s the second-highest in this list. If you are looking for a compact unit that can give you good value for your money, then this may be the best choice for you.

Filtration Performance

Although quite small, this powerful water filter is extremely capable of reducing a huge percentage of contaminants that water treatment facilities fail to remove as well as those picked up along the way.

The filtration media the system uses is a special blend of granulated carbon and silver that have been grounded to microparticles, screened, and then blended together rather than layered.

This filter design provides a large surface area hence ensuring optimum contact time with the water which extremely boosts the absorption ability of the filter making it super effective at extracting contaminants from the water.

It will be able to remove 99.99% of chlorine and lead plus many more other contaminants like VOCs, carcinogens, chloramine, as well as heavy metals such as mercury and chromium 6.

It will filter out turbidity too and get rid of that unpleasant odor and tastes often caused by most of the chemical contaminants in the water. In addition to that, the Woder 8K is bacteriostatic, so it will prevent the growth of bacteria, mold or any other microorganisms within the filter.

Its special blend of media also gives it a selective filtration ability which clears out harmful impurities but keeps all the essential minerals that are vital to our health, including calcium, magnesium, and potassium. Therefore, you and the family will get to enjoy a healthy and great-tasting purified water.

Capacity and Efficiency

This Woder WD-S-8K-DC is an under sink water filter with a large capacity as it can process up to 8, 480 gallons of water before needing a change of filter which is the second-highest capacity on this list.

It means it can last more than 3 years with normal use hence it’s ideal for long-term use. If you are not a fun of changing filters frequently, this will fit you right. 

Regarding the flow rate, the filter will deliver around 2 gallons of water a minute at 65 psi which is the average rate of most under sink filters. The best part is the fact that it uses microparticles means that it will be able to remain optimally effective while purifying your water for those 3 years.

However, this will only be possible if you make sure you use it with municipally treated cold water alone or at least disinfected water, not well water.

Installation and Maintenance

With its simple and compact design, the installation process of the Woder 8K is easy and straightforward. It shouldn’t take more than 5 minutes. The package features all the parts you need including the direct connect hoses.

You just mount it where you want and connect it directly to your 3/8” cold water line under the sink and the existing standard cold water valve faucet. You don’t need a separate dedicated faucet to dispense the filtered water.

Low maintenance is another advantage you will get from this filter since it can for about 3 years before requiring changing and it has a built-in valve to allow you to perform the replacement without turning off the water. You will have to replace the whole thing though.

To sum it all, Woder WD-S-8K-DC is a very capable under sink water filter that will give you amazing value for your money, especially because of its high capacity. It’s a suitable choice for city water and its construction feels solid and strong, so you are assured durability.
