My bottle seems to be leaking. What do I do?
Down Arrow Icon Minus Icon

When filling up your 321 Filter Bottle make sure there is no water in the bottle top or on the outside of the container where you screw it on. We don't want any water getting trapped in the threads as it will come out while drinking. 

My water has turned black, what happened?
Down Arrow Icon Minus Icon

Don’t freak out! This is completely natural. Your filter is made from an activated carbon and the first time it passes through water it leaves a residue.

This is great, it means that the filter is working!

We recommend that after your first plunge, you refill and plunge again to ensure the filter will not leave any residue on the next fill.

What is my filter made of and what does it do?
Down Arrow Icon Minus Icon

Activated Carbon.

Activated carbon is a natural, highly porous filtering material prepared by exposing organic materials such as coconut shells to high temperatures and steam, creating an enormous surface area for absorption. 

The filter significantly reduces chlorine and removes odours and bad tastes.  

It does not remove fluoride. 

This super-porous carbon is used to absorb impurities from potable tap water such as odours, tastes, organic compounds and residual chlorine. It is low impact, aesthetically pleasing, durable, portable, and free of harmful chemicals, for you to enjoy every last drop.

When do I need to replace my filter?
Down Arrow Icon Minus Icon

The best thing you can do is click here to sign up for a 321 Water Filter Reminder. 

Our filter lasts around 125 refills. That is an amazing 62.5 litres of great tasting water before it needs replacing.

If you are struggling to remember this, then the best way to remember is that a frequent user will need to change the filter monthly.  Though if you don’t hydrate as regularly, then bi-monthly should do the trick. 

Can I use my product in countries where it is not safe to drink tap water?
Down Arrow Icon Minus Icon

Unfortunately, no.  321 Water is only to be used with tap water that has been treated and is safe to drink. 321 Water doesn't make undrinkable water drinkable. However, it is a great idea to take 321 Water with you when travelling. You could also use a product such as Aquatabs to treat the water, then use 321Water to plunge away the 'funny taste' of the treated the water.
