What is the difference between Regular and Alkaline?

The AquaTru Alkaline Set combines our advanced 4-stage filtration process, which removes up to 99% of heavy metals, pharmaceutical residues, microplastics, and other contaminants, with an Alkaline VOC carbon filter that restores healthy minerals and increases pH. The result is clean, mineral-rich water that tastes as good as it is for you.

Le filtre pré-charbon (étapes 1 et 2) élimine les bactéries, les sédiments et autres grosses particules de l’eau potable. Il est compatible avec le système AquaTru Under Sink. Le charbon actif réduit également le goût de chlore pour une eau plus agréable à boire. Comme ce filtre retient les particules les plus importantes, il doit être remplacé tous les 6 mois afin d’éviter tout encrassement de votre appareil.

Le filtre pré-charbon (1-2) de votre AquaTru Under Sink doit être changé tous les 6 mois.

When should you replace your filters?

To keep your AquaTru Under Sink system performing at its best, filters should be replaced according to the recommended schedule or when you notice changes in water flow or taste. Unlike countertop systems, your Under Sink unit does not use indicator lights so staying on top of regular filter changes is key to maintaining optimal performance. Delaying filter replacement can reduce filtration efficiency, allowing contaminants to build up over time and affect water quality. Regular maintenance helps ensure clean, great-tasting water and extends the lifespan of your system.

Need help replacing your filters?

Simple steps to keep your AquaTru system performing at its best.

1. Shut off the cold water supply line connected to your system.
2. Open the RO faucet to drain any remaining water.
3. Twist and remove the filter.
Tip: The filter can pivot out for easier access
4. Insert and secure the new filter until fully in place.
5. Write the installation date on the filter to track replacements easily.
Tip: Use our helpful Filter Replacement Records chart.
6. Close the faucet and turn the cold water supply back on.
