Five More Water Filter Pitchers Tested

We tested five more water filter pitchers (Aquagear, Berkey, Brita, Kirkland, and LifeStraw) and found surprising results.

While all did an excellent job of removing the heavy metals lead, cadmium, and mercury, pitchers varied dramatically in their ability to remove chlorine, (which affects taste), fluoride, arsenic, total dissolved solids (TDS), and microplastic particles. Be aware that some pitchers actually increase the amount of microplastics in water after filtering!

See our Top Picks for:

• Removing Chlorine Taste
• Reducing Fluoride
• Removing Arsenic
• Reducing Earthy Taste (due to high TDS)
