Product description
Key Benefits
- Naturally purifies and improves the taste of tap water.
- Removes chlorine and add minerals.
- Each filter lasts for up to 6 months.
Made from premium Binchotan charcoal, this filter harnesses traditional Japanese methods to purify and soften water. Binchotan charcoal is sourced sustainably from the branches of fast-growing trees in Laos, ensuring minimal environmental impact. The charcoal's active carbon works effectively to absorb impurities like chlorine, leaving water free from unpleasant tastes and odours.
Designed to fit most bottles and jugs, it starts working within an hour and filters 1.1L of water daily, lasting up to three months. When it needs a refresh, simply boil it for 10 minutes to extend its life by another 3 months. Even if it breaks, the charcoal pieces can still be used, making this an easy, sustainable way to reduce waste while enjoying better hydration every day.

I cannot say if it
I cannot say if it changed anything in my well-being, but that's the best alternative I've found so far to water in glass.

The best wellbeing website…
The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.

Amazing!
Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!

Great products, service, and customer support
Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf
It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
