Water Filter 2021 Test: Which Brand Wins?

the AquaTru did by far the best job yet at improving the appearance of the water. 35 parts per million, which is just about as good as the ZeroWater... the AquaTru definitely seems to have come out on top

the ZeroWater did by far the best job yet at improving the appearance of the water, zero parts per million

Aquafor actually did better than the homemade filter at 221 parts per million

the Berkey did by far the best job yet at improving the appearance of the water. It pretty much left all the dissolved solids in the water though at 359 parts per million

the Brita did a little bit better at removing dissolved solids at 265 parts per million

the Survivor makes pretty quick work at filtering the water, but the water looks about the same as the LifeStraw. 355 parts per million

the water still looks pretty bright red even after it's been filtered by the PUR brand. 302 parts per million

the appearance of the water improved slightly with the Filtrete, but it didn't perform nearly as well as the ZeroWater. 335 parts per million

the appearance of the LifeStraw water looks to be about the same as the Filtrete. 343 parts per million

the water filtered by the Sawyer is about the same color as the unfiltered water. 343 parts per million

the RV filter did quite a bit better job than some of the other brands at improving the appearance of the water. However, there's still quite a bit of dissolved solids in the water at 348 parts per million

the appearance of the Frieling water just doesn't seem to be as clear as some of the other brands. 665 parts per million

the homemade filter actually cleaned up the water a little and it's now at 248 parts per million compared to 364 for the untreated water

the AquaTru reverse osmosis did very well at only 36 parts per million

the ZeroWater filter lives up to its reputation, zero parts per million

Aquafor did slightly better than homemade filter at 233 parts per million

which is actually higher than the unfiltered water. After doing some research, this is pretty common in the Berkey filters when the filters are new

the Brita performed nearly the same as the Aquafor at 234 parts per million

the Survivor Filter Pro performed fairly well at 231 parts per million

for the PUR brand

for the Filtrete

for the LifeStraw

the Sawyer didn't perform as well as the Aquafor at 256 parts per million

so pretty close to the unfiltered tap water

so there's definitely a little bit of improvement

AquaTru and ZeroWater came out on top at 0 mg per liter

the ZeroWater has done by far the best job yet at improving the appearance of the water. Zero parts per million, very impressive. The test strip is showing less than 5 mg per liter, which is by far the best yet

the Aquaphor actually did a pretty good job at removing the iron. It appears to be around 5 to 10 mg per liter

the Berkey water appears to have around 50 mg per liter of iron content

the test strip for the Brita is showing that it did a better job removing the iron than some of the other brands at around 50 mg per liter

the Survivor didn't do much to change the color of the water, it did a pretty good job at improving the transparency. 616 parts per million

the Pur definitely seems to perform better than the RV filter at around 100 parts per million for iron

the LifeStraw performed about as well as the Sawyer at 600 parts per million. It appears to be around 100 mg per liter of iron content

the test strip is showing that the Sawyer didn't do nearly as well as the Aquaphor at removing the iron

the RV filter didn't perform as well as the Aquaphor or Sawyer at 617 parts per million. Unfortunately, the water that passed through the RV filter still has quite a bit of iron left in it

the test strip showed that the Frieling water actually did a pretty good job at removing the iron at 50 mg per liter

... the test strip is showing that the homemade water filter left quite a bit of iron in the water
