49mg Water Purification Tablets (30 Pack). Portable Water Purifier for Camping Essentials, Lightweight Camping Gear or Survival Kit, EPA Registered & NSF/ANSI 60 Certified, Fast-Acting

YOU NEED CLEAN WATER Love these. Great to have on hand at any time. Approved by the WHO organization for safety. I've done a lot of camping in the past and wish I had had these back then. We are getting 10 to 14in of snow this weekend and having these on hand has given me piece of mind. I dont know if it helps but if I feel I ate something bad or maybe a cold starting these seam to help take the edge of especially if you get food poisoning. Great price, practical, perfect for travel, survival preparedness, snowstorm, power outages, camping, 1 small tablet in a bottled water shake wait drink. Low odor. Smells like chlorine. Very convenient easy to take anywhere being a small light weight product. Should be in everyone's emergency survival kit. Thank you for a practical necessary easy to use affordable product!!!

I’d fill my one liter stainless steel water bottle with lake water. Pop in one tab. Agitate/shake periodically while waiting 30 mins. Water smelled fresh (kinda like a faint pool water smell). Drank it. Had several liters over the weekend camping trips. No issues. A great backup to have in your backpack.

But as back up for mechanical water, purification absolutely works as it’s supposed to. I’ve used it many times. It is a great backup to have

I used these in the backcountry for the first time yesterday and have no reason to believe they aren't effective. There is a mild chlorine taste but it's minimal and fully masked by any electrolyte powder or anything of that sort. My main issue with this is that I don't find the packaging convenient or intuitive, especially for the environment I was using them in. The pills are small and it's hard to identify where they are in the pouch / figure out exactly where to open it. I crushed one pill on accident trying to open it and lost another.

I used these to treat all of my drinking water on a recent backpacking trip. I found them to be very simple to use, extremely lightweight, effective, and to have very little chlorine taste (I’ve had worse tap water!). I find some of the reviews complaining about the taste to be questionable, or maybe they used the wrong dosage, or are individuals who are extremely sensitive to the taste of chlorine. I also like that this product protects your water from recontamination for up to 24hrs in a closed container. Price per treatment is also very good and this product is made in the EU (Ireland). It can’t kill cryptosporidium on its own, so I use a two step system of filter (platypus QuickDraw), then treatment with aquatabs. Peace of mind knowing that my water is safe to drink. Update (1 Year of field use) I’ve been using Aquatabs on every backcountry trip this past year, including treating water for groups. Depending on the water source, I’ve even forgone pre-filtering. I (and my fellow hikers) haven’t experienced any waterborne illness and no one has complained about chlorine taste. I’ve even converted my companions away from chlorine dioxide tablets and iodine. Aquatabs are so convenient to use and inexpensive, they’re always in my pack.

Would buy again, great to have for emergencies

A must have for your emergency kit. Water is essential and you need potable water. Remember emergency situations happen be prepared.

Great value for the money! Works great for cleaning larger amounts of water.

Seguramente es buen producto. Pero pedí la versión para 1 litro y llegó versión para 20 l. No lo puedo usar.

Aún no me veo en una situación en las que tenga que probarlas, pero al menos el empaque me dejó satisfecho pues están individualmente bien empacadas, así que espero no ir a tener problemas con ellas en una emergencia.

El producto llegó a tiempo y fue tal cual como lo solicitamos. Buscarlo directo en tiendas es difícil por lo que la compra por Amazon fue una excelente idea.

Son una buena opción para emergencias. Por su tamaño son muy prácticas y prácticamente no ocupan espacio, ideales para llevar en una mochila. Tienen fecha de caducidad prolongada y en mi caso llegaron en su empaque original y caja cerrada, lo cual da confianza. Son una solución sencilla cuando no se tiene acceso a agua potable. El sabor del agua puede cambiar ligeramente, como es normal en este tipo de tratamiento, pero cumplen su función. No sustituyen un sistema de filtración más completo si el agua está muy sucia, pero como método de desinfección funcionan bien. Son un buen complemento para un kit de purificación de agua en una mochila de emergencia.

Acaban de llegar, tienen un tamaño adecuado para integrarse al botiquín, aun no las uso después actualizo este punto
