In independent PFAS testing, all 14 compounds in the test panel came back "Not Detected" after treatment. That's the kind of result you normally see from whole-house systems costing thousands more.

Setup took under 10 minutes with no tools required. The 4-stage filtration process takes about 15 minutes to purify 11 cups - roughly 0.04 GPM. That's slow, but you're getting hospital-grade water purity.

The 4:1 water efficiency is exceptional for reverse osmosis. Traditional under-sink RO systems waste 3-4 gallons for every gallon produced. AquaTru wastes just 1 gallon per 4 gallons purified.

What Could Be Better: At $449 MSRP ($349 on sale), this is a significant investment. Annual filter costs run $100-120. The unit removes beneficial minerals like calcium and magnesium, so you may want to remineralize or buy their alkaline filter add-on. Some users report leaking issues with earlier units.
