|Pros||Inexpensive for an under the sink filter, removes tons of lead and chlorine||Fantastic at removing impurities, makes great tasting water, inexpensive||Great contaminant removal, fairly inexpensive||Great at removing both lead and chlorine, makes great tasting water||Performed well in our lead removal, chlorine removal, and salt removal tests|
|Cons||Filtered water didn’t taste amazing, didn’t remove minerals well||Smaller capacity, takes some time to refill and refilter||Slow flow rate||Mediocre flow rate, pricey||Low flow rate, pricey|
|Bottom Line||If you aren’t a fan of water filter pitchers and are looking to save some cash, then the APEC WFS-1000 gives you the best bang for the buck||The best water filter we have seen by far, delivering an unmatched performance at an amazing price||This filter jug delivered excellent results in our impurity removal tests and is very easy to use||If constantly refilling a pitcher water filter is too much of a hassle, then the iSpring is a great choice||While this filter did deliver a solid performance overall, other less expensive filters gave a much better performance|

Our Analysis and Test Results
The WFS-1000 finished in the middle of the group overall and was outperformed by the most of the other under the sink filters: Home Master HydroPerfection, iSpring RCC7, and the APEC Essence. The WFS-1000 is on par with this trio when it came to extracting chlorine or lead, but fell far short in our mineral removal test. However, the WFS-1000 is much less expensive, ranging anywhere from $20 to $350 cheaper, making it a much better value.
To rank and score these products in our quest to find the best possible water filter, we researched all of the top products, then bought all of the most promising to test side-by-side. We conducted several different tests, divided up over five weighted rating metrics, with the results of the WFS-1000 detailed below.
Comprising a quarter of the overall score for each filter, we evaluated how well each filter did at extracting lead from water for this metric. The APEC WFS-1000 got off to a strong start, removing essentially all of the lead and finishing in the top-tier of water filters.
We contaminated our experimental water supply with lead until it was significantly higher than the EPA acceptable level of 0.015 ppm — about 2.3 ppm, according to the results of the water quality lab. When we ran this water through the WFS-1000, it reduced the concentration to around 0.012ppm — about 1.25 times less than the EPA standard. This calculates out to a reduction of about 99.48%.
Moving on from lead, our Chlorine Removal metric is also worth 25% of the final score. We followed a similar procedure as our lead test, using chlorine bleach to spike the concentration of the isolated supply, then testing the concentration of the filtered water using chlorine test strips. The WFS-1000 again delivered an exceptional performance, putting it right at the top of the group.
Differing from the lead test, we actually conducted two different trials for this metric — one with extremely high chlorine levels, on the order of 1000 times the level in a swimming pool, and one with more moderate levels, on the order of 5-10 times as much as a pool. The WFS-1000 did an extremely good job in both tests, dropping the concentration to around 0 ppm, or at least low enough that the test strips failed to indicate anything. We found this to be particularly impressive, as the high concentration test had far more chlorine than these products should ever come close to encountering through normal use.
Unfortunately, the WFS-1000 couldn't maintain its strong performance through all of our impurity removal metrics, delivering an exceptionally lackluster performance and finishing near the bottom of the group in this test.
We used standard sodium chloride (table salt) as our contaminant, mixing it into our water supply until we measured levels of around 445 ppm, according to our TDS meter. The WFS-1000 barely made a dent in this, failing to remove even 10% of the salt and leaving the filtered water tasting so salty that it was close to undrinkable.
After the WFS-1000's somewhat shoddy performance in the previous metric, we didn't expect much from it in our Taste metric, as this also involved filtering out salt. We weren't wrong, with the APEC earning a 5 out of 10 for its mediocre showing in this metric, which accounts for 15% of the overall score.
However, this filter did deliver a decent showing in the first component of this metric. We ran pure water through each filter, then had our taste-testing panel try each one to see if there were any undesirable flavors imparted on the water. The majority of our panel rated this water from good to excellent, with no detectable unsavory flavors imparted.
For the second test, we ran heavily chlorinated and salted water through each filter, again having our panel rate the results from each filter. The water produced by the WFS-1000 was exceptionally salty and not really something that anyone really wanted to drink.
For the last test, responsible for the remaining 10% of the score, we timed how long it took for each filter to produce a quart of water. The WFS-1000 finished on a high note, having one of the highest flow rates of the group.
This filter took 15 seconds to fill the container, only about 6 seconds longer than the standard faucet.
This filter is an exceptional value, giving you the most bang for the buck of all the under the sink or faucet models, earning it the Best Buy Award.
The APEC WFS-1000 does a great job of pulling lead and chlorine from your water, without pulling out too much cash from your bank account. It's not the greatest option if your water is full of minerals that you would like to remove or if you are shopping on a tight budget. If that is the case, then you should definitely look at a water filter pitcher instead.
