How AquaTru Purifiers Work

Every AquaTru filter has one job, and they work together to get your water fully purified.

  • Pre/Carbon Filter: Captures sediment and rust, then reduces chlorine and chloramine for cleaner-tasting water. Replaced every 6-months.
  • Reverse Osmosis Filter: Reduces lead, arsenic, chromium-6, and other heavy metals. Replaced every 1-year.
  • VOC Carbon Filter: Reduces VOCs and "forever chemicals" like PFOA and PFOS. Replaced every 2-years.

Dr. Corey Herbert stands confidently with arms crossed beside an AQUA Tru water filtration system.

"One of the most popular pitcher filters that everybody thinks of is only certified to remove 8 contaminants. AquaTru is certified to remove 84. There’s really no comparison."
