Recent Water Purifier Reviews

Platypus Meta Bottle + Microfilter

rated 4 of 5 stars A quick easy water filtration bottle. Scoop and drink treated water directly from the bottle or squeeze water through the filter into another vessel. When I first received the Platypus Meta bottle with Microfilter I thought it was just another filtered water bottle. Well, I was wrong, as it has become my go-to water treatment device for hiking and backpacking. Platypus took its already popular Meta soft bottle and added a removable micro-filter to the top that allows me to drink directly from… Full review

MSR SweetWater Purifier System

rated 5 of 5 stars Solid performer. After using the old porcelain Katydin filters of the '80s, this SweetWater was revolutionary. You could actually fill a poly bottle in a reasonable amount of time, and it is lightweight. I bought my first one in the '90s and we are on our second cartridge and just replaced the yellowed tubes last year, on the second pump. We usually put a pan in the stream and let the water run over the edge, that way you don't suck up the particles that plug the cartridge up. If it spits water… Full review

MSR Guardian Purifier

rated 4.5 of 5 stars The MSR Guardian is a top of the line water purification system that delivers on its impressive claims. Very fast, very efficient, and largely hassle-free (requires no backflushing). Excellent for the solo hiker, but perfect for larger groups. Disclaimer: This review is purely on design, usability, durability, and my overall opinion of the product. Without access to a water testing laboratory, I cannot make any claims regarding the actual efficacy for removing harmful impurities (biological and… Full review

Grayl Quest

rated 3 of 5 stars I Love the concept! I just question how well it works. It says to just push down on cartridge and once it reaches the bottom water is purified. It says it should take 30-60 seconds to push down. When I tried it went down very quickly. I was afraid to actually bring it to Nicaragua with me and try it. I really wanted this to work for me. The Grayl Quest Purifier is an all-in-one system. The system itself claims to last over 10 years. I felt like the pressure I was applying wasn't enough to prove… Full review

First Need Deluxe Water Purifier

rated 5 of 5 stars Reliable, versatile, and fast. Reliable, versatile, and fast. I purchased my unit well over 20 years ago. Used it on hikes in the Coast and Cascades ranges of Oregon and Washington. And really put it to the test while while trekking in Myanmar, Central America, and travels from Ghana to Namibia. Purified water from very suspect sources. Never had an issue, never suffered from water borne problems. Definitely a lifesaver and definitely a product to recommend.  Full review

Potable Aqua Pure

rated 4 of 5 stars This rechargeable water purifier is an innovative, extremely low maintenance device that almost anyone can use to treat drinking water. Through the process of electrolysis, the Potable Aqua PURE breaks the NaCl molecule in a simple salt water brine solution that produces Chlorine and Peroxide. From backpacking to emergency disaster relief, this small device can be used in a multitude of environments. The reaction chamber in action, fizzing and bubbling The device with its included brine container,… Full review

SteriPEN Classic

rated 5 of 5 stars I've had multiple ways to filter water. I've use drops, tablets, pumps, and used gravity. I've settled on the SteriPEN UV filtration system. I love the ease of use. I simply fill a Nalgene, turn on the light source, and in about 90 seconds I have drinkable water. It includes a pre-filter to keep floaties out. SteriPEN, like most filters, keeps out over 99% of most of the things that can make you sick. It comes with a pre-filter, but if the water is really dirty, I also use a clean bandanna.  The… Full review

SteriPEN Classic 3 with Pre-Filter

rated 3.5 of 5 stars Works very well, but is restricted to certain water containers due to size. I really love this product.  However, it only works with certain bottle sizes.  I don't enjoy the requirement of bringing heavier bottles that will fit the pre-filter.  On the other hand, with good batteries, it lasts quite long. It takes about 30 seconds to treat 0.5L, or about a minute for 1 L. This is fine for one person, but it eventually takes quite a while for a large group, with infrequent water sources (lots of… Full review

First Need Deluxe Water Purifier

rated 5 of 5 stars The only real choice if you want to remove all the nasty bugs/chemicals from your water source with a single self-contained device. I’ve had this First Need purifier for nearly a decade and it has served me and my hiking/backpacking buddies well. Most importantly, this is not simply a water filter but a chemical-free purifier. That means you don’t have to use the chemicals other require or the addition of iodine to make water safe to consume. This means it removes a lot of those difficult to… Full review
