Who it fits
Good fit for

You will appreciate the leak detection feature if you are often away from home. The alkaline filter adds minerals back into the water. The dedicated faucet ensures clean water is always available.

Who should skip it
You should look elsewhere if you need a high-flow system for filling large pots quickly. The 1.7-gallon storage tank means you must wait for the system to refill after heavy use.

Key specs for AquaTru
Design: Under sink
This unit fits inside your kitchen cabinet. You save counter space by keeping the system hidden. The footprint is 16.3 inches wide and 11 inches deep. It requires a dedicated faucet for dispensing water. You must check your cabinet dimensions before buying. This design suits homes with limited counter room.
Filtration Stages: 4
The system uses four distinct filters to clean your water. This includes pre-filtration, reverse osmosis, and post-filtration stages. Each stage targets specific contaminants for thorough purification. You get cleaner water than single-stage filters provide. This setup is standard for effective under-sink reverse osmosis systems. It balances performance with maintenance simplicity.
Certification: NSF/ANSI (IAPMO)
The unit is certified by IAPMO to meet NSF/ANSI standards. This verifies that the system actually reduces listed contaminants like lead and fluoride. You do not need to guess if it works. Independent testing confirms the claims. This certification is a key safety benchmark. Look for similar certifications when comparing other reverse osmosis units for reliable performance.
Filtration Type: Reverse osmosis, alkaline
This system combines reverse osmosis with an alkaline filter. Reverse osmosis removes dissolved solids and contaminants. The alkaline stage adds minerals to improve taste. You get purified water with a balanced pH. This dual approach offers purity and flavor. It differs from basic reverse osmosis units. Compare this if you prefer mineral-enhanced water.
Design and build specs
The AquaTru Under Sink Alkaline RO System is built for hidden installation. According to the listing, the unit measures 16.3 inches wide, 11 inches deep, and 20 inches high. These dimensions determine whether it fits inside your specific kitchen cabinet. You must verify your available space before purchasing. The system occupies a compact footprint, allowing you to keep the main filtration components out of sight.
The dedicated faucet comes in three finish options: matte black, polished chrome, or stainless steel. You select the color that matches your existing kitchen hardware. The faucet provides on-demand access to the stored water. The system holds up to 1.7 gallons of purified water in a dedicated tank. This capacity ensures you have enough clean water for daily tasks without waiting for the filtration process to complete.
The control panel manages the system's operation. It includes alerts for filter changes and battery status. A leak detector is also integrated into the design. If a leak is detected, the panel sounds an alert and automatically shuts off the cold water line. This feature helps prevent water damage. The layout prioritizes safety and maintenance reminders. You receive a manifold, filters, tubing, and an installation kit. The components are arranged to simplify the under-sink setup process.
Setup and daily operation
The AquaTru Under Sink Alkaline RO System requires a dedicated faucet for dispensing water. The listing includes a stainless steel faucet in matte black, polished chrome, or stainless steel finishes, along with tubing and an installation kit. You install the unit under your sink, where it connects to the cold water line. The system includes a manifold and a TruPure RO Sanitizer to prepare the components for use. Daily operation relies on a control panel that monitors system health. This panel displays filter change alerts, battery status, and leak detection information. You can reset the panel using the dedicated button. A key feature is the automatic leak detection. If a leak is detected, the unit sounds an alert and shuts off the cold water line to prevent further flow. This mechanism helps protect your cabinetry from water damage. The system stores up to 1.7 gallons of purified water in a dedicated tank. This capacity allows for on-demand access without waiting for filtration. You use this water for drinking, coffee, tea, ice cubes, cooking, baby formula, and pet bowls. The four-stage filtration removes contaminants certified by IAPMO to NSF/ANSI standards. Filter replacement intervals vary by stage. The Pre/Carbon Filter lasts up to six months. The VOC Carbon Filter lasts up to one year. The Reverse Osmosis Filter lasts up to two years. You monitor these intervals via the control panel alerts. The system is designed for consistent, clean water output directly from your faucet.
Before you buy this system
You must verify your cabinet dimensions before ordering. The unit measures 16.3 inches wide, 11 inches deep, and 20 inches high. Ensure your under-sink space accommodates these measurements with room for connections. You need a dedicated faucet installation point. The listing includes a faucet, but you must confirm the hole size in your sink matches the included model. Filter replacement is part of regular upkeep. The pre-filter and carbon filter require changes every six months. The RO filter lasts up to two years, while the VOC carbon filter needs attention annually. You should budget for these recurring replacements. This system competes with other under-sink options by offering alkaline filtration and a leak detection feature. Check if other models provide similar storage capacity or faster flow rates. Compare the filter lifespan and certification details against other RO systems to find the best fit for your household needs.
