Built for city apartment dwellers who need to strip heavy metals and chlorine from aging municipal pipes without installing a bulky reverse osmosis rig. Not for off-grid well users or those dealing with high bacterial loads — this shop focuses on chemical and particulate reduction via Ion-Exchange fiber.
Curator's pick: Aquaphor Crystal Under Sink Water Filter System
Pitchers are fine for tea, but if you actually cook with water, the flow rate on this under-sink unit is the only thing that won't annoy you. It utilizes the same Aqualen density but at a pressure that doesn't feel like watching paint dry.
⚠ Worth knowing: While the Aqualen technology is effective at preventing 'channeling' in the media, these cartridges are proprietary and you won't find generic replacements at the local hardware store. If you don't keep a spare Maxfor+ set on hand, you'll be stuck drinking tap for three days while waiting on shipping.

How to use this together
1
Start with a Filter Pitcher
Begin by selecting an Aquaphor filter pitcher like the Amethyst or Provence. Wash the pitcher, insert the Aquaphor Maxfor+ or A5 replacement filter according to instructions, and fill with tap water. This provides immediate access to filtered drinking water, helping you experience the difference.
2
Install the Under-Sink System
For a continuous supply of filtered water directly from your tap, install or have the Aquaphor Crystal Under Sink Water Filter System installed. This system typically connects to your cold water line, providing filtered water for cooking and drinking without the need for manual refills. Follow the detailed plumbing instructions for proper installation.
3
Maintain with Replacement Filters
Regularly replace the filter cartridges for both your pitcher and under-sink system. The Aquaphor Maxfor+ cartridges are for pitchers, while the A5 filter is available for enhanced hard water treatment. This ensures sustained protection against heavy metals and constant access to clean water. Replacing filters on schedule is crucial for consistent performance.
