Ultra UV Water Purifier

Outstanding piece of kit. Great design, easy to use and it works! A week of drinking tap water in Nigeria and not a single tummy trouble. The locals thought I was mad!

Ordered this as doing Everest Base Camp trek later this year. Tried it to check it works. Very easy to use, follow the on screen instructions, you can not go wrong. Would recommend

Great for making water safe to drink, I use it when camping and I haven’t got sick drinking local water (not treated) small sleek came in a pouch that you can attach to your bottle our you belt. It is very quick you just dip the light into you full water bottle for one minute and that is it clean water.

Charged for the recommended 5.5 hours after receipt. Followed insructions for use and it appeared to work for the first test with the UV light coming on but then going out before the countdown had finished. IThe UV light now does not come on at all when tested and the count down is not displaying. This was bought to take on a trip to India as a way of establishing confidence in being able to drink local water. The fact that it is unreliable is not merely disappointing; the pen actually constitutes a danger to health for someone exposed to contaminated water. Unreiable and dangerous. Buy at your peril

Why did you choose this product over others?: Life saver while touring the world especially places like India and Nepal where you can't even trust bottled water.

Used this on a hike to sterilise water from a stream. Very impressed, good quality, easy to use.

It arrived as described and I was not disappointed. I used it throughout my Pacific Crest Trail and was never ill. I rarely had to charge the battery, it kept a really good charge all the way. Easy to use and so quick, I drank well on my hike.

I will be doing a lot of travelling next year so I will update this review accordingly. The pen itself appears to be well made and durable. The controls consist of one button, press once for a full ltr or twice for Half a ltr. Job done, could not be easier. My only critique would be the size and weight but there are smaller, lighter versions available. It also comes with a durable storage case that will attach to a belt or webbing. UPDATE. This unit went faulty after 5 or 6 uses. My initial impression on durability was incorrect. I will update this review after I have contacted the manufacturer. Katadyns Response to a warranty issue is that as the backlight can’t be fixed I should use a flashlight or a timer as the pen still works. Laughable from such a company.

Compre el steripen porque salgo de acampada de vez en cuando y necesitaba saber que el agua que bebo está limpia y descontaminada , , lo uso incluso en casa porque por curiosidad herví agua mineral que compro y se me quedaron unos residuos que me parecían muy sospechosos y decidí que por seguridad lo usaré en casa también , es de uso muy fácil súper cómodo , se carga con USB y yo como tengo un panel solar tampoco me cuesta cargarlo y la verdad es que lo compre exactamente por su forma de cargar que es súper útil , las pilas no me parecen muy buena opcion porque si no tengo en el momento no podré usarlo , me parece estupendo y súper útil , el envío fue muy rápido y llego en perfecto estado

Buen servicio.

I used this for the first time while hiking in Patagonia, and it was the perfect solution to ease my worry about drinking from mountain streams. Super lightweight for my daypack, and took the exact amount of time I needed for the occasional short break. Takes away the need to carry a ton of water with you while hiking or camping in any place with natural water -- so perfect.

Nous l’avons utilisé à de nombreuses reprises pour boire l’eau des ruisseaux dans des campagnes riches en élevage. Il s’est avérée extrêmement pratique avec ma gourde à larfe goulot, achetée sur Amazon (en titane, 1100 ml et avec sacoche). C’est un super combo. J’utilisais un textile pour filtrer les impuretés puis sterilisais l’eau dans la gourdes. Avec les gourdes classiques à goulot étroit ou les casseroles trop peu profondes, c’était un peu la galère: je n’avais pas assez d’amplitude pour remuer oublient les électrodes de détection ne touchaient pas assez l’eau. Dans ces cas-là, le steripen arrête le processus de décontamination par sécurité; ce qui est très bien. Bref, j’ai toute confiance dans cet objet que je recommande.

I bought the SteriPEN for a different use case than I suspect most other people have. I have a long term sinus condition that requires me to irrigate my nose & sinuses frequently, two or three times per day. My ENT doc made it clear that using plain tap water may have germs that cause infection and is unsafe for nasal irrigation. Unfortunately, that meant that it was necessary to boil water in advance & store it in sterilized containers, or else buy gallon containers of distilled water. My wife and I travel fairly frequently, so we had to take water with us---a hassle if you travel by car, and impossible if you travel by plane. Then one day, after months of this, it occurred to me that UV sterilization might be an option to replace boiled or distilled water. I shopped on Amazon, and found the SteriPEN products and read both the product descriptions and user reviews. The SteriPEN Ultra USB Rechargeable seemed like a really great fit. Before I purchased the SteriPEN, though, I talked to my ENT about whether it would be safe to use to sterilize the water I use for nasal irrigation. He 'blessed' the idea with no hesitation. I ordered the unit from Amazon and have been using it now for several weeks with no ill effects. It has proved to be a huge help to me--no sterilized glass jars, no gallon plastic jugs--in the convenience of preparing the water I use to make my irrigation solution. I use the SteriPEN on its 'half liter' setting to sterilize two cups of water at a time; I get the water from the tap & in less than a minute I've got water that I can safely use to irrigate with. The battery charge lasts a long time--weeks, not days--and when its time to recharge I just plug it in the USB on my computer and let it sit overnight. One thing I want to make clear: in the literature that comes with the product, the manufacturer says clearly that the SteriPEN is NOT a sterilizer. I think this is something their lawyers made them say, because if the unit doesn't sterilize, why would anyone buy the product. But be that as it may, for the record let me state that I didn't rely on their literature or advertising for my use of their product. I thought up this usage on my own, and I ran it by my doctor and got his OK. So, if you think you might want to use it for an application similar to the one I have described here, I urge you to get your doctor's approval before proceeding. I'm very happy with this product. It really works well for me, has excellent build quality, and hopefully will last a long time.
