SteriPEN Ultralight UV Water Purifier

This was invaluable on my trip to Africa. I used it each and every day. I am immunocompromised and have to be vigilant with my health traveling abroad. I wish it worked a bit faster, but otherwise, zero critiques. Excellent product. Worth its weight in gold. I’ll never travel without it!

This sure does work. Water bugs are killed with this magic wand. The blue light turns on once it contacts with water. All you have to do is stock in the glass or water container and just stick in the water and watch it light up. Then just move around in circles and it will turn off to tell you it done. It can be charge in three ways 1. Solar panel charge if your in the open, 2. Battery power charge, 3. House power outlet.

Took this on a Montana hunting trip, worked reasonably well. Then I trusted it on a backcountry Appalachian hunting trip and it failed. I was six + miles in and it was hot and suddenly I had no way to get water because it had lost its (full) charge. So I attached it to my portable charger and it wouldn’t charge. I would not trust this thing for water acquisition. Get a filter like a sawyer.

Unfortunately, I don’t have any way to prove that this product actually works, but I can say when I was out of the country it did provide me with the significant piece of mind, knowing that I could brush my teeth with water that had been treated in some way. I never got sick either so I think that’s a good sign.

This is a great product and seems to be high quality. It's easy to use, and while a bit on the clunky side, still not overly large. The only downside is how long it takes to work. I brought it with me on a trip through Southeast Asia but never ended up using it, just drank a lot of bottled water instead. If you're in the wilderness, though, I think it'd be a great pack companion. I'd feel safe drinking water after using it.

Great unit - nice to feel confident I won't get sick. Esp when combined with the BeFree filter so the water has less contaminants in it before UV blasting. :-)

This has come in very handy in places where water is iffy! Haven’t used it for backpaking yet but it’s very lightweight and should be great for that. Foolproof too and easy to charge.

I was traveling for 3 months around the US and concerned about the water quality in unfamiliar areas. Purchased this filter for travel and will keep at the ready at home for emergency use.

Super gadżet 👍

funktioniert gut, ist sehr klein. Wer auf Akkus steht, ist gut bedient. Wer Batterien bevorzugt, muss weiter suchen.

Preso per la mia attività escursionistica. In accoppiata con un filtro meccanico (nel mio caso Sawyer Micro) consente la totale e sicura eliminazione di batteri, protozoi, larve di tenia, alghe e virus. Ciò consente di poter fare rifornimento d'acqua anche da una pozzanghera fangosa o da un fontanile dove il bestiame si abbevera, e persino da un laghetto con escrementi di bestiame. Non è in grado di eliminare l'inquinamento chimico o da metalli pesanti ma non è un problema che si riscontra in escursione (se si evita di abbeverarsi da sorgenti sulfuree). Il peso è molto ridotto e l'autonomia, di una ventina di litri con una carica, consente di portarlo dietro anche in escursioni di molti giorni. Porto comunque sempre delle pastiglie di cloro nel caso mi ritrovassi con l'apparecchio danneggiato o le batterie scariche. Attenzione che il "vetro" in quarzo è delicato e l'oggetto va trattato con garbo.

Pour le bushcraft et les survivalistes, probablement le plus efficace des systèmes de purification d'eau, car en quelques minutes, il agit sur toutes les bactéries, virus et parasites pathogènes pour l'homme. Mieux que tous les filtres qui pour la très grande majorité, n'agissent pas sur les virus ; ou le Micropur forte (efficace sur les mêmes pathogènes) mais dont l'utilisation quotidienne peut-être dangereuse pour notre flore bactérienne intestinale et peut créer des troubles digestifs à terme. Mieux que l'ébullition qui détruit une partie des minéraux et oligo-éléments de l'eau. C'est exactement le même principe que le système SODIS qui utilise le soleil, mais en infiniment plus rapide.

Just received today. Can't wait to use it.
