Overall, we weren't terribly impressed with the faucet mount filters, but if we had to pick one, then we would go with the BRITA SAFF-100. While this model didn't do very well in our lead and mineral removal tests, it has a decent flow rate and extracted the bulk of the chlorine from the water supply in our tests. It's also relatively inexpensive compared to many of the other filters in our tests, so if you want a faucet mount filter and you are only really concerned about removing chlorine from your water, the SAFF-100 is a solid choice.

|Pros||Inexpensive, removes tons of chlorine||Fantastic at removing impurities, makes great tasting water, inexpensive||Great at removing both lead and chlorine, makes great tasting water||Performed well in our lead removal, chlorine removal, and salt removal tests||Inexpensive for an under the sink filter, removes tons of lead and chlorine|
|Cons||Didn’t do well in our lead or salt removal tests||Smaller capacity, takes some time to refill and refilter||Mediocre flow rate, pricey||Low flow rate, pricey||Filtered water didn’t taste amazing, didn’t remove minerals well|
|Bottom Line||If you are set on a faucet mount filter, then the SAFF-100 is your best bet||Doing a fantastic job in most of our tests, the ZeroWater combines an amazing performance with an even better price||The best filter for permanent installation that we have seen to date||This relatively expensive under the sink model was outperformed by products that cost much less||If you are set on an under the sink filter and are shopping on a budget, the WFS-1000 is the perfect choice|

Our Analysis and Test Results
This filter finished in the middle of the group overall, behind the APEC WFS-1000. However, there was a marked drop in performance between these two filters, with the SAFF-100 scoring almost 20 points lower. However, it is much less expensive and does almost as good of a job at extracting chlorine from the tap water.
To rank and score these products, we did extensive research and analysis on practically every water filter that currently exists. We then selected the most promising models and bought them to test head-to-head in a variety of challenges. The results of the SAFF-100 in our weighted rating metrics are described below.
Worth 25% of the overall score, our Lead Removal metric evaluated each water filter on how well it extracted this heavy metal from its supply water. We did this by dissolving lead shavings in peracetic acid, then mixing this into the isolated water supply of our filter testing apparatus. We took samples for the water quality lab of the supply and the water after it had passed through each filter, then scored based on the results, looking at the percentage of lead removed and if the filtered water met the acceptable lead standard as set out by the EPA.
The SAFF-100 did a decent job, earning it a 6 out of 10. While this filter did remove about 97.13% of the lead from the contaminated water, the filtered water still had levels that were a little more than four times higher than the EPA acceptable level, 0.066 ppm to 0.015 ppm. However, our supply water did have extremely high concentrations of lead at 2.3 ppm — much, much higher than these filters should encounter in typical use.
Again, our Chlorine Removal metric constituted a quarter of the overall score for each home water filter. We made two batches of chlorinated water — one with over 1000 ppm and one with between 20-50 ppm — to run through our filters and assess their skills at extracting chlorine. The BRITA SAFF-100 actually delivered a great performance in this impurity removal metric, earning a 9 out of 10 for its stellar showing.
This filter did very well with the lower level chlorine test, completing removing all of it to the point where the chlorine test strips would not change color at all. However, some chlorine did sneak through when we ran the highly chlorinated water through it, with the filtered water registering about 10-20 ppm of chlorine remaining after filtration
This metric tested how well each filter did at removing dissolved salts from the water supply. It also constitutes 25% of the total score, identical to the prior two metrics. The BRITA SAFF-100 delivered a dismal performance, earning a 1 out of 10. This filter failed to remove essentially any of the salt, with the water showing salt levels around 445 ppm, both before and after filtration.
For the pair of taste tests, worth 15% of the overall score, we used a panel of taste testers to score and rank the water produced by each filter. They weren't the biggest fan of the water produced by the filter, causing the SAFF-100 to earn a 5 out of 10 for its overall lackluster performance.
Initially, we ran clean water through each filter, to see if our taste testers noticed any unsavory or undesirable flavors added to the water by the filters. Our pane didn't note any distinct additions by the SAFF-100, but it just wasn't quite as crisp and clean-tasting as before it went through the filter.
For the second test, we made some very foul-tasting water by dissolving salt and chlorine bleach into the experimental water supply, then ran this through each filter. The BRITA failed to remove all of the contaminants, producing filtered water that was very salty with a slight hint of chlorine, though this was a slight improvement to the exceptionally undrinkable supply water.
For the last metric of our testing process, we looked at how long it took each filter to fill up a quart container, as no one wants to be standing there for ages to fill up your coffee pot in the morning. This test is responsible for the last 10% of the score, with the BRITA SAFF-100 doing a decent job, earning a 5 out of 10.
This filter took about 25 seconds to fill a quart container — about 2.5 times longer than the unimpeded faucet's 9 seconds.
This filter is a decent value, though you can get a better bang for your buck by purchasing other filters that cost less and performed better.
While the BRITA SAFF-100 is our favorite of the faucet mount filters, we still weren't too impressed by its performance overall, causing us to favor the under the sink or pitcher filters much more.
