Filtering water bottles clean your water as you drink or fill. The choices range from insulated steel bottles with carbon filters in the cap to press and straw styles meant for camping. The best one depends on whether you want better tasting tap water or protection on the trail.
The six below cover a range of designs and uses. We have not used these products ourselves, so confirm what each filter claims to remove, its capacity and the replacement schedule on the current listing before buying. Be careful to match the filter to your water source. Think about where you drink most, because a bottle that suits your desk may be a poor fit for a trail, and the reverse is also true.

The Short Version
For design, LARQ Filtered. For a steel hiking bottle, LifeStraw Go Stainless. For fast purifying, Grayl GeoPress. For insulation, Brita Insulated. For a budget bottle, Seychelle. For light packs, Katadyn BeFree. Decide first whether you need taste improvement or true purification, then buy accordingly, and always confirm the stated removal claims on the current listing. It also helps to think about weight and carrying style, since a heavy steel bottle is great on a desk but tiring on a long trail. If you travel by air, empty the bottle at security and refill it afterwards, and check the maker’s guidance on whether the filter should be removed or stored dry between trips.
