Turn flat RO water into mineral-rich alkaline water. One filter. One twist.
Reverse osmosis strips out contaminants — but also the minerals that make water taste alive. This quick-change alkaline post-filter installs downstream of any RO system and does two things: it polishes purified water through a 0.5-micron carbon block for pristine taste, then passes it through an alkaline mineral remineralisation layer that restores a balanced pH of 7.5+ and reintroduces essential trace minerals. The result is water that's both ultra-pure and naturally balanced.
0.5 Micron Carbon Block + Alkaline Mineral Media: The PLC cartridge combines a fine 0.5-micron activated carbon block with alkaline remineralisation media in a single replaceable core. The carbon stage reduces lead, heavy metals, sediment, chlorine, and bad taste, while the mineral stage enriches the water with calcium, magnesium, and trace elements — elevating pH to a healthy alkaline level. Beneficial minerals are added, not removed.
True Quick-Change Design: No wrench. No housing to unscrew. The cartridge twists directly into a compact head unit — pull the old one out, click the new one in. Filter changes take about 2 seconds. The built-in automatic water shut-off stops flow the moment you remove the cartridge, so there's no mess and no need to turn off your water supply.
Universal 1/4" Quick-Connect Compatibility: Standard 1/4" push-fit inlet and outlet connections make this filter compatible with virtually any under-sink reverse osmosis system on the market. Connect the inlet from your RO system's pure water output, run the outlet to your dedicated drinking water tap, and you're done.
Pairs Perfectly with Any RO System: Whether you're running a compact 2-filter RO unit or a full multi-stage system, this post-filter slots in as the final stage. The installation diagram is simple: cold water supply → your RO system → this TAM4 filter → dedicated tap. It can be wall-mounted or placed freestanding inside the cabinet.
Compact, Sleek Form Factor: At just 17 × 11.5 × 38 cm and 3 kg packaged, the ALK4 takes up minimal space under your sink. The matte black head unit with quick-connect fittings gives it a clean, professional look.
Key Features:
What's in the Box: Quick-change filter head unit with mounting bracket × 1 · PLC alkaline mineral + carbon block cartridge (0.5μm, pre-installed) × 1 · 1/4" inlet tubing × 1 · 1/4" outlet tubing × 1 · User manual
Installation: Connects inline between your RO system's pure water output and your dedicated drinking water tap using 1/4" quick-connect tubing. Wall-mount the head unit or place it freestanding in your sink cabinet. No electricity, no drain line, no additional plumbing required.
Note: Designed for use after a reverse osmosis system. Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection.
Pure water, perfected. One twist at a time.
Most families assume their tap water is safe because it looks clear. But safe by regulation and actually clean are two very different standards, and the gap between them is wider than you think.
This is not about buying a filter. It is about removing a problem you have been absorbing every single day, and noticing the difference within the first week.
Most people do not think about it because the cost is spread across dozens of small purchases. But add it up over a year and the number is hard to ignore.
| Water Source | Annual Cost | Quality |
|---|---|---|
| Bottled Water (family of 4) | €1,200 – €2,400/yr | Inconsistent, plastic leaching |
| Basic Pitcher Filter | €80 – €180/yr | Removes chlorine taste only |
| Water Delivery Service | €600 – €1,000/yr | Decent, but inconvenient |
| Hydrion Filtration System | €0.08/litre (first year incl.) | 99.9% contaminant removal |
Based on average European household consumption of 8L per day. Filter replacement costs included.
One path changes nothing. The other removes a problem you will wish you had dealt with sooner.
Everything you need is in the box. No plumber required. Most people are up and running in 20 to 30 minutes with the included quick-connect fittings.
Run the system for 15 minutes to prime the filters. Use the included TDS meter or the built-in display to see your water quality drop in real time.
Turn on the tap and it is clean. Filters last 6 to 12 months depending on your model. The system tells you when to swap, takes 3 seconds.
One purchase. Years of clean water. The math works, the science works, and the guarantee means you have nothing to lose.
