Replacement filter set 4-in-1 Pure Water Tap

Purified water only stays pure with fresh filters. This original 3-part replacement filter set keeps your PureAqua 4-in-1 and 5-in-1 tap at full strength for a whole year, so your water is always as pure and great-tasting as on day one.

Why replace on time?
Your filters continuously capture limescale, chlorine, PFAS, microplastics and other unwanted substances. Over time they become saturated and the purification declines. A fresh set immediately restores full filter performance and the fresh taste.

The three filters in this set
Together they form the complete reverse osmosis process of your tap:

• Combo Nano: the pre-filter. Captures particles, rust, chlorine and limescale before the water reaches the membrane, protecting the heart of the system.
• RO 3500: the reverse osmosis membrane. This is where the real work happens: up to ~99% of PFAS, microplastics, heavy metals and limescale, among others, is filtered out.
• Remineralising Alkaline PLUS: the post-filter. Adds valuable minerals such as calcium and magnesium back and gives your water a soft, fresh taste with a natural pH.

Whether you draw boiling, hot, cold or filtered water, or sparkling water from your CO₂ cylinder with the 5-in-1 tap, you always drink fully purified, great-tasting water.

Carefree to use

• Lasts 12 months with normal use
• Fits the 4-in-1 and 5-in-1 tap exactly: original filters, no fiddling with universal sizes
• Replace it yourself in a few minutes, without tools

Never think about it again
With the filter subscription, you automatically receive a fresh set every 12 months. You pay on delivery, get a message in advance and cancel whenever you like. Prefer to order one-off? That's fine too: the subscription is a choice, not a requirement.
