If you love backpacking, camping, and trekking, you should be looking for the best portable water filter.

It is why it’s crucial to find a portable water filter that works simply and straightforwardly to supply us with clean, fresh water. However, it can be daunting to choose one without a clear idea on the top picks on the market. This guide is for you! Read for the top 12 picks, each with distinct features and qualities. Let’s get started.

1. Sawyer Products Water Filtration

Sawyer lets you experience the lightest and most compact system to use, literally. The Sawyer Products MINI Water Filtration System weighs in at only 2 ounces but delivers heavyweight performance.

Considered as one of the most compact filters available on the market, it is small enough to fit into the palm of your hand. But you’d be surprised by how well it performs, its flexibility, and ease of use. It can even let you drink straight from a lake or stream by merely using a straw that comes with it, making it the perfect on the go water filter.

Its thick hollow fiber membranes with small inner diameter make them 75 percent stronger than other membranes and allow fast flow. It uses a topnotch 0.1-micron filter that removes 99.99% of all kinds of bacteria and protozoa. It is very convenient to use. Just fill your water bottle or the included reusable pouch, screw the filter to it, and start sipping. Its screen can be attached to most water bottles.

The MINI Water Filtration System lets you do a little bit of maintenance by using a cleaning syringe to backflush the filter. It is a neat feature for removing sediments from the screen and helps make the device last for a long time while maintaining its high flow rate. Sawyer claims that the filter can be back washed continually to restore up to 98 percent of its flow rate.

California is experiencing a serious drought and no Californian can afford to waste any water. We all need to do our part.


While DEET products may be more familiar by name and their chemical smell, sprays with 20 percent picaridin, like Sawyer Products, offer comparable protection without the harsh odor and oily feeling on your skin.

The Sawyer Squeeze was (by far) the most common Pacific Crest Trail water filter this year – for the fifth year in a row. It’s a $39, 3 oz / 85 g hollow fiber filter that rids your drinking water of protozoa and bacteria (and floaties). It can be used with Sawyer bags (included with the filter) or with compatible water bottles (Smartwater is the bottle of choice for many hikers).

SAWYER MINI WATER FILTER, $22 This has been my water filter of choice for years now. The bags can be iffy — I have had a few break – so carry a couple. However, the filter itself is reliable, light and inexpensive. -Logan
