About Water-to-Go bottles
EcoActive bottles take a replaceable filter and come in three capacities: 550 ml, 750 ml and 1 litre. Replacement filters are sold separately, and each is rated for up to 200 litres. Water-to-Go says its current filters fit its current bottles, so check the model first if you own an older one.
Which size?
The 550 ml suits a small bag or a short trip. The 1 litre means fewer refills, but a full litre adds about a kilogram of water. The 750 ml sits between the two. Filter costs per litre, sizes and care are on the Water-to-Go bottles guide.
Choosing a bottle for untreated water?

Common questions
Does the code apply automatically?
No. Our buttons take you to the product page, and you enter WTGAW20 yourself at checkout.
When does it expire?
We haven’t been given an end date. Offers can change or end, so check the total at checkout before you pay.
Does it work on replacement filters?
We have confirmed the code on a bottle only. Add filters to your basket and look at the total before you pay.
Is delivery included?
Delivery is worked out at checkout and is separate from the discount. Water-to-Go’s UK site shows free delivery above £49.99, which may not apply to every UK address.
What if the code isn’t accepted?
Check it is typed exactly as WTGAW20 in the discount code box. If it still fails, the item or basket may not qualify or the offer may have ended, and Water-to-Go’s checkout will say so.
Is this Water-to-Go’s own page?
No. Tap Sorted is an independent UK guide. You buy from Water-to-Go, and its terms apply to your order.
