What you get
Product Description

The green alternative for your replacment anti-limescale undersink water filter.

You already have one of our ASC4000 cartridges.

The cartridge itself - ie the plastic casing - can work for at least 2 or 3 years. And it’s refillable.

So instead of us sending you a new cartridge every time you need to change, and you throwing the casing away, this way we simply send you this refill media sachet.

The only downside is that you have to pour the media into the cartridge yourself - But this is very easy to do. It only takes literally a couple of minutes and we send you full and easy instructions.

Plus you get a discount !

What's not to like? It's a win / win - for you (all of us!) and our planet.

The media will store perfectly well if kept in a cool dry place - and this saves on unnecessary deliveries.

You simply pour it into the cartridge every time you need it.

Refilling literally takes a few minutes every few months.

If and when you think you need a new plastic cartridge casing simply let us know and we'll send one out for free (ideally when you reorder these refill packs so we can again save the unecessary carbon cost of the extra delivery to you)
Disposing of the used media: Unfortunately the media itself is not recycleable. Once used, simply dispose of in your normal household waste.
