This complete set of K5, K2 and K7M cartridges ensures your system continues to deliver clean, safe, and great-tasting water every day. Built for reliability and ease of use, these filters work together across multiple stages of filtration, removing impurities while preserving essential minerals for balanced, high-quality drinking water.

Why Choose This Product

Designed exclusively for the Aquaphor RO-101S system, this replacement filter pack ensures your system continues to perform exactly as intended.

Multi-Stage Filtration Performance

The K5 and K2 cartridges remove coarse particles such as sand and clay, along with common impurities including chlorine, lead, and bacteria, ensuring cleaner and safer water at every stage.

The K7M cartridge completes the process by conditioning the water and adding essential minerals back in, improving taste while maintaining water quality.

Why Replacing Your Filters Actually Matters

Most people wait too long to replace their filters. That is where problems start. Your RO system does not suddenly fail. It slowly declines. By the time you notice, your water quality has already dropped.

What Happens If You Do Not Replace Them

Filtration performance drops

Clogged filters cannot remove contaminants effectively. Chlorine, heavy metals, and fine particles begin to pass through.

Water taste gets worse

That clean, crisp taste disappears. You may notice dull, flat, or slightly unpleasant water.

Bacteria risk increases

Old filters can become a breeding ground for bacteria rather than a barrier against it.

System strain and damage

Blocked cartridges force the system to work harder, reducing efficiency and potentially shortening the lifespan of your RO unit.

You lose the benefit of remineralisation

The K7M stage is designed to restore essential minerals. When it is exhausted, your water loses balance and quality.

Why replacing your RO filters matters

Why do RO filters need replacing?

Your RO system relies on each filter stage doing its job properly. Over time, cartridges become loaded with contaminants and lose effectiveness. Replacing them keeps water quality high and your system performing as intended.

What happens if you do not replace them?

Performance drops. Water taste worsens, filtration weakens, and contaminants can begin to pass through. You stop getting the quality your system was designed to deliver.

Can old filters damage the system?

Yes. Blocked filters increase strain on the system, reducing efficiency and potentially shortening its lifespan. Timely replacement protects both performance and hardware.

How often should these filters be replaced?

Every 18 to 24 months. Leaving it longer increases the risk of reduced filtration and unnecessary system wear.

What does each filter actually do?
  • K5 removes sediment and larger particles
  • K2 reduces chlorine, lead, and fine impurities
  • K7M completes purification and adds essential minerals
Why replace filters before you notice a problem?

Because once you notice it, performance has already declined. Staying ahead keeps water quality consistent and avoids unnecessary strain on your system.
