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.

Does it require installation?
Unlike our countertop purifiers, AquaTru Under Sink requires installation. We recommend hiring a certified plumber to install your reverse osmosis system. Installation requires drilling into your pipes under the sink, which is not recommended for individuals unfamiliar with plumbing. Please read through the owner’s manual carefully before attempting to install the system. Proper installation is the responsibility of the installer. If you have any questions or need assistance, please contact our technical support team, who can guide you through the installation process.
What filters does it use and how long do the filters last?
Our AquaTru Under Sink purifier uses the same filter materials as our countertop units, and has the following filter lives:
- Pre-Filter (yellow): 6 months or 600 gallons, whichever comes first
- RO Filter (blue): 2 years or 1200 gallons, whichever comes first
- VOC Filter (green): 1 year or 600 gallons, whichever comes first
What makes the TruPure RO Sanitizer unique?
Normally, under sink reverse osmosis holding tanks can be a breeding ground for bacteria, if not properly maintained. Most people don’t realize they need to sanitize their tank, and usually, the process involves tubing and a plastic syringe. No, thanks. That’s why we developed our patent-pending, TruPureTM RO Sanitizer that makes it easy to keep your AquaTru holding tank in pristine condition. Simply unscrew the TruPureTM RO Sanitizer, pour in the sanitizing solution, and complete the sanitizing steps only once per year when you change your VOC filter. Just another way AquaTru ensures that you have pure, great-tasting water.
