Water Purifier for Sink | AquaTru® Under Sink

Long-Lasting Filters

Step 1 & 2: Pre/Carbon Filter

A mechanical Pre-Filter captures larger particles like sediment and rust, while a Carbon Filter removes chlorine and chloramines for cleaner, better-tasting water.

Lasts 6 months for consistent, high-quality filtration.

Stage 3: Reverse Osmosis Purification

An ultra-fine R.O. filter eliminates harmful inorganic chemicals, including lead, chromium-6, arsenic, nitrates, and heavy metals.

Lasts 2 years for continuous, advanced purification.

Stage 4: VOC Carbon Filtration

A coconut shell carbon block filter reduces volatile organic compounds (VOCs), including rocket fuel, prescription drug residue, and “forever chemicals” (PFOS & PFOA)—leaving you with pure, great-tasting water.

Lasts 1 year for superior contaminant reduction.

What is the TruPure™ RO Sanitizer?

Normally, under-sink reverse osmosis systems require manual tank sanitizing. The process often involves messy tubing, plastic syringes, and multiple steps most homeowners don’t even realize are necessary.

Over time, holding tanks can become a breeding ground for bacteria if not properly maintained.

That’s why we developed the patent-pending TruPure™ RO Sanitizer.

Instead of complicated tools and guesswork, TruPure™ makes annual sanitizing simple and clean. Just unscrew the sanitizer cap, pour in the sanitizing solution, and complete the remaining steps once per year when you replace your VOC filter.

No syringes.
No complicated tubing.
No hassle.

Just another way AquaTru helps ensure your water stays pure, fresh, and great-tasting year after year."
Does the AquaTru Under Sink use the same filters as the AquaTru Carafe?

No. The AquaTru Under Sink uses Classic filters that are not compatible with Carafe filters.
