How Your Filters Work Together

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 2-years.
  • VOC Carbon Filter: Reduces VOCs and "forever chemicals" like PFOA and PFOS. Replaced every 1-year.

"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."

Love it! Cleanest water ive

"Love it! Cleanest water ive tasted ever and you can tell how clean because it never leaves anybresidue lines on carafe. Filters are expensive but unfortunatelu necessary due to toxic chemicals, metal pharmaceuticals and the list is too long to mention here. Worth evey penny and its Certified always a plus plus plus. Thankyou for this product. I do hope the price comes down so everyone can afford clean drinking and coolong water. A must for the health of mankind. God Bless you Mrs Arthur"

The new filter seems to

"The new filter seems to work fine, but we have pretty good water here already, so it is hard to tell how much of a difference it makes. I did appreciate also receiving the filter removal tool, however. Another thing I do appreciate about this filter is that if after filling the rear carafe with tap water, you forget to also put the empty front carafe in its proper place, it won't work. Without that I would have made a big mess in my bathroom."

I just started using it

"I just started using it a few days ago, but I am very pleased so far. Everything has been very clear and easy to understand. All of the hard work has already been done before the box arrives. Very professional. I am absolutely thrilled that I found AquaTru. I can rest assured that my family is drinking the safest and best tasting water. Thanks so much."

AQUATRU has been a game

"AQUATRU has been a game changer in our water consumption. For years we were drinking plastic bottle water and were concerned about the harmful plastic in the water. Now with AQUATRU that is no longer a concern and we drink so much more better tasting better for our health water!!"

We love not having to

"We love not having to buy bottled water anymore and not having to change filter monthly. However I give 4 stars because the tank has been really difficult to get set on the connection tightly and the time it takes to filter seems to have slowed down. We purchased this in July 2026"

— Diane K. (4/5)

"They have sent me the wrong product twice now. Do not order from them if you value your time. You will have to spend time correcting their mess ups."

— Kieran (1/5)

We have been using the

"We have been using the Aqua Tru Carafe system for just over a year and are very happy with it. The combo pack will maintain our system for another year. This is a much cheaper system that performs as well as an under sink system, but allows us to take it with us (if we move) and make use of the residual water on ornamental plants."

— Raymond I. (5/5)
