Our Verdict

The Woder 10K-Gen3 Is No Longer Available as of Winter 2019

The Woder 10K-Gen3 delivered an overall unimpressive performance in our tests, making us hesitant to recommend it. While it is the least expensive of the under the sink models, it also delivered uninspiring performance in our tests relative to competing filters we tested. However, it does have a few redeeming traits, doing a decent job at extracting chlorine from the water supply and having one of the highest flow rates of the group. Unfortunately, it is quite hard to overlook this filter's lackluster performances in our lead and mineral removal metrics, as well as our taste test.

Our Analysis and Test Results

The Woder finished in the middle of the group, right behind the BRITA SAFF-100. However, the SAFF-100 was far superior in our tests at extracting lead and chlorine from water. Neither of these filters did very well at extracting minerals from the water or made water that tasted particularly great. The SAFF-100 also usually retails for about a third of the cost of the Woder, making it much more desirable in our opinion.

Overall  the Woder failed to impress.

Performance Comparison


To decide which water filters are really worth our recommendation, we conducted extensive research, then bought all of the filters that had the most potential to test side-by-side. The results of the Woder are explained in the sections below, comparing how this filter did against the rest of the other models that we reviewed.

Lead Removal


The 10K-Gen3 didn't get off to a good start with this metric, delivering a substandard performance in our tests and earning a 4 out of 10. We evaluated this by running water with very high levels of lead through each filter, then sending the filtered water off to an independent lab for analysis.

This lab found that our supply water had lead concentrations of around 2.3 ppm — significantly higher than the 0.015 ppm deemed allowable by the EPA. The Woder removed about 93% of the lead, but failed to meet the standard, with lead levels about 10 times higher than the allowable amount in the filtered water, as measured by the lab.

Chlorine Removal


The Woder 10K fared much better in our chlorine removal tests, earning a 7 out of 10 for its solid performance. We made two batches of chlorinated water, one with very high levels of chlorine and one with much more moderate levels, then used indicator strips as well as an electronic meter to assess how much chlorine each filter removed.

The Woder didn't do very well with the highly chlorinated water, with the test strips still maxing out when measuring the filtered water. However, the Woder did remove all of the chlorine from the less chlorinated water, with the strips failing to indicate anything.

Salt Removal


Unfortunately, the Woder's performance plummeted in this metric, with this filter failing to remove any of our sample salt. Consequently, this filter earned a 1 out of 10 due to its performance in this test. We used table salt, dissolving it into the water supply for our filters until our meter registered levels of about 445 ppm. After running it through the Woder, we measured the filtered water, finding that the concentration remained unchanged.

We weren't fans of drinking the water produced by the Woder.

Taste


The Woder continued its lackluster performance in our taste tests, delivering a mediocre showing in each of the assessments in this metric, earning it a 4 out of 10.

For the first test, we used already purified water for the supply of the filters, then had a panel taste the water after it had been filtered by the Woder. This was to see if the Woder added any unpleasant or unsavory flavors. It did, making clean water taste a bit stale and generally unpalatable to our water tasting judges.

Next, we made a batch of exceptionally undrinkable water using chlorine bleach and salt, then ran it through the 10K-Gen3. It did improve the flavor a decent amount, but definitely didn't improve the test of the water to a level our panel considered to be drinkable.

Flow


The Woder actually has one of the highest flow rates of the group, earning it top marks and a 10 out of 10. To determine scores, we timed how long it took the Woder to fill up a 1-quart vessel. The Woder only took about 12 seconds — just a little bit more time than the standard faucet's 9 seconds.

Value


While this is one of the least expensive under the sink filters we have tested, it isn't an amazing value, as we found its performance in our tests to be disappointing overall compared to competitors we tested.

Conclusion


The Woder 10K-Gen3 is not a water filter we'd recommend to a friend unless their primary interests were in fast flow rate and filtering out chlorine, the two areas in our tests in performed very strongly versus competitors.
