## Overview

The MSR Guardian Purifier is a military-grade portable water purifier featuring advanced hollow fiber filter cartridges that remove viruses, bacteria, and protozoans. It self-cleans with every pump, purifies water at a rapid 2.5 liters per minute, and is built to endure extreme conditions. Lightweight and compact, it’s the ultimate hydration solution for serious travelers, backpackers, and emergency responders.

## Description

Height: 21 cm, diameter: 12 cm, weight: 490 g. Hollow fibres offer the most reliable form of water treatment, functional in many conditions that may arise in practice. Harmful microbes and dirt particles in the water are mechanically retained and removed, when flowing through the hollow fibres. The modern, portable water steriliser by ‘guardian water sterilisers’ was developed to facilitate the purification of water in a safe and easy manner anywhere in the world. The product was developed in conjunction with the US military and uses the latest technology. It is a useful tool for travellers, backpackers and emergency rescue services. New hollow fibre technology facilitates the purification of extremely dirty water and reliably removes germs and even viruses from the water. The ultimate protection: advanced hollow fibre filter cartridges meet the test standards of the US military for the removal of viruses, protozoans and bacteria.

Review: Best piece of kit I have bought in years - Amazing piece of equipment. Used it for a 6 night backpacker hike within the Kruger National Park and it performed phenomenally well. We had to dig water wells in the Limpopo river bed and the filtered water was perfect - no latent taste of water purification tablets or drops that one normally has to use. I used it in conjunction with a 6 litre dromedary bag and provided water for everyone on our trip. At 2.5 litres per minute the unit filters quickly. It's not the cheapest filtering system, but in my opinion it's well worth the expense. I would definitely recommend this filter to any serious hiker / backpacker (or even holiday maker) who might need to take water from a questionable source.
Review: Repair - Hi i need a new part for this filter i purchased.. who can i contact please. It's a great filter just had a little accident

### ⭐⭐⭐⭐⭐ Review
*by 焼***ん on 2 December 2025*

個人で持つことのできる浄水器では最もハイエンドな部類になるかと思います。こちらはウィルスも除去できるタイプで、予算が厳しいのならもう1ランク下げて2万円台のミニワークスEXで浄水したものを煮沸すれば対応できます。 断水時には一人一日３Lと言われていますが、これは本当に最低限の数値です。4人家族が3Lで7日間しのぐとしても訳９０Lの水が必要です。 局所的な災害であれば、給水車の2日以内に来てくれるでしょうが、大規模災害となると下手すると1ヶ月以上断水する可能性があります。そうなると水の単価は恐ろしく跳ね上がることでしょう。 7万円の浄水器は確かに高いですが、そのような非常時に陥った時にこの7万円は決して高いとは思えないと思います。
