I picked this slick little unit up because I hate the taste of iodine and I didn't feel like hauling around a water filter. This unit is very small, light, and easy to use once you know how (figure it out at home first).
My complaint with the unit is that I was assuming I would be getting taste-free water treatment. This is not the case. It makes the water taste like rather heavily chlorinated city water, and smell faintly like a swimming pool. It's nowhere near as bad as iodine, but it was still an unfortunate and unexpected surprise. You could probably hide the taste with flavour crystals, but I like my water pure, especially in the outdoors.
Personally, I think I'll probably end up going with a standard water filter instead.

I purchased a Miox a few years ago. I am planning a week long trip on the river with my son, so I took the Miox out of storage and decided to test it before I took it to the river.
I'm glad I did because it doesn't work anymore. I have put new batteries and salt in it and it keeps giving me a low salt warning light. I guess it's back to the filter and the bleach.

Although this seems wonderful product, it is of no use without any safety indicator strips. And if you live in the Netherlands it is impossible to find those in any shop (no reordering there), and if there is some found at the back of à shelf, it is grossly expired and does not work.
Ordering any by internet does not work also as all MSR products are not sent from US. So we are very disappointed with this product.

Purchased this unit for two uses. Primarily for traveling out of the USA and use on backpacking/camping trips where the water source will be relatively clear.
For traveling over the last two years I've taken along a Sweetwater filter and the MSR MIOX. The water sources have been not clear, little funky smelling and potential viral contaminate. Clear and clean tap water to drink. I found that by letting the water sit for a day the pool smell and flavor is reduced or disappears. For camping I still prefer the Sweetwater.
Positives are: Compact, relatively light, simple to use and effective against bacteria, protozoa and virus. A water purifier.
Negatives are: It's not a filter. So sediment, color, odor, chemical in your water can be a problem. The lithium A123 batteries do not last for a long trip (3-4L/day x 30days). Bring spares for an extended vacation.
4 Stars, not 5 because of its limitation of maybe having to drink unclear water and residual chlorine taste.

Really like this unit. I use it as a backup and for purifying large amounts of water at a single time. I found that you must practice with this unit to get it right to avoid the "swimming pool" smell that most mention. It's small, highly portable, quick and efficient...what more can I say?

Bought this for hiking and emergency situations. It will purify large amounts (liters) of water. Highly recommend practicing with this unit repeatedly until its use is 2nd nature. In an emergency situation, this will be time well spent. It's a great design, light and capable. Find some water and this thing will clean it up.

Upsides: It works and is lightweight, and kills some nasties that iodine tablets don't kill. When I'm hiking anywhere that there's good-tasting water available (e.g. the Sierra Nevada), this is what I take to handle purification duties. The chlorine taste is similar to many cities' water and is far less annoying than iodine taste. Consumables are cheap. There's no moving parts to break or wear out.
Downsides: It's not a filter, so doesn't improve the taste of the water (aside from removing tannins, that icky "dead leaf" taste, which however does use a lot of chlorine so overchlorinate) and doesn't remove floaties from the water. If you're hiking somewhere that the majority of water is scummy cow tank water, carry the extra pound of scrubbable ceramic-based filter with you (with a coffee filter prefilter), your taste buds will thank you.
A bit fussy with the residual chlorine strips (though you'll mostly use them for less-than-prestine water where you want to know how much to overchlorinate). Too expensive if you only go hiking a few times a year, you can get chlorine dioxide tablets that do the same thing. Does use batteries, and the batteries do need to be kept warm in cold weather for this thing to work right.

I agree with some others: Yes, it does smell and taste like a swimming pool. MSR was not honest about that. I've used it hundreds of times over a year, in four continents. Besides the taste, the thing is amazing in every way. I tried to make as many travellers as possible feel bad about buying bottled water (it's a huge waste problem overseas) by showing them this thing.

I picked up the MIOX unit before going on a Mt. Rainier climb. It's easy to use and as long as you follow the directions and wait times it will give you safe water (from virus, bacteria, etc.).
It does leave a slight taste and as my friend found out the solution it creates will act like bleach to your clothing if you spill it on yourself. The only issue I've found it that the test strips indicate a "too low" for the standard treatment. I solved this by treating for one step higher than the standard. It may just be the water sources I'm using. I don't consider a fault of the unit as it does its job.

Excellent water purifier, small, light, compact, and reliable. It produces chlorine dioxide, the same effective chemical used in Aquamira and Micropur tabs, which means that it will kill crypto, unlike iodine or plain chlorine treatments.
I have found that the Miox Pen produces odorless, clean-tasting water with no chlorine taste, when properly used on backcountry water sources according to directions with proper dosages and wait times. Some people have poured the Miox Pen oxidants into already-chlorinated city water sources and decry the 'swimming pool' taste, not realizing that such a procedure will only intensify the taste of already-present residual chlorine. Read the directions and you should have no problems.

Price Paid: $120 CDN
I have owned and used the Miox for one ice climbing season and one summer backpacking season. While I would probably prefer a traditional water filter in the summer, in the dead of winter this isn't an option.
I find the Miox indispensible in the winter. The unit is small enough to store in your belay parka (to keep the batteries warm), easy to use with liner gloves, and the reactive chemicals work fast enough with warmed water (melted snow) to be drinkable within 15 minutes. In my opinion it's better than Aquamira unless you're an ultralight hiker counting the grams.
The unit is easy to use and the indicator lights make it virtually idiot-proof. Also, the option of double or triple dosing is a lot easier than using bottled chemicals. If you can get the water lukewarm, this little unit can do the rest. Use with a bandana "pre-filter" for great results.

Price Paid: $120
The MSR Miox pen is a small compact water treatment unit. The original Miox Pen (identical in operation to the MSR commercial unit) was first issued to our soldiers in Afghanistan. It is lightweight and stores easily. It is also economical over time. I got many backpacking trips and water treatments out of a single salt tablet and the original set of batteries.
There is a big misconception among those who aren't familiar with the Miox and its chemical treatment engineering, and who rather simplistically dismiss the Miox Pen as only a 'chlorine maker'. The Miox Pen does NOT produce simple sodium hypochlorite (otherwise known as commercial bottled chlorine). Instead the unit uses salt, water and electrolysis to produce a complex compound of mixed oxidant chlorides that is effective against all bacteria, viruses and parasites, including crypto, which ordinary bottled commercial chlorine WILL NOT kill.
Another misconception is health effects. What some critics don't realize is that Miox has used the exact same technology to produce water treatment for third world and military applications for years with no ill effects. If it's safe enough for the U.N. and U.S. special forces, it's safe enough for me. I love my Miox!

This is a cute little compact chlorine maker. If you want chlorinated water why not just bring a small bottle of bleach along? I'm returning mine because chlorine is bad for us.
