I've used these several times over the past year, and compared to other chemical water treatments they're relatively painless. You don't have to force yourself to down chemical-tasting water.

To the earlier reviewer who mentioned treatment time: 4 hours is a worst-case scenario mandated by the EPA for killing one type of organism (cryptosporidium) in water that is both very cold and very dirty. All bacteria and viruses, except cryptosporidium and giardia, are killed in 15 minutes (even in cold water). Cryptosporidium and giardia are both killed in 30. In cold, very dirty (cloudy) water, it can take 4 hours for a full crypto kill.

We took these tablets to Bangladesh, and used them on a daily basis. You do have to wait three hours to make sure all the microorganisms are killed, but the water tasted fine, and no one got sick, so these seemed to work well for us.

My friend and I went on a five day backpacking trip in CA, and hands down, these tablets produced the most normal tasting water. We had access to plenty of lakes, streams, and sometimes a pond looking pool of water. We didn't take a chance, so we treated all sources with this and a different brand. Although other brands took only a few minutes, this one takes at least four hours to treat. Other brands actually change the color into an orange color, but this Katadyn makes the water clear and we couldn't tell the difference.

Again the four hour treatment time takes a bit of planning, but definitely worth it.

One has to weigh the advantages and disadvantages of this product based on one's needs or requirements. IMO, the pros and cons are...
Pros: These tabs weigh only a few ounces, but can treat up to 20 liters.
They are very effective at killing off viruses, bacteria, Giardia, and Cryptosporidium(EPA accepted). This product is great if you can't build a fire or boil water.
Cons: One tab for one liter so unless you stock up, you can only support one person for 5 days if you use 1 gal. or 4 liters per day for roughly $10. Compare this to 96oz(~56000 drops) of Clorox for $4 and it only takes 16 drops to treat 1gal. of water. Katadyn claims that their tabs leave virtually no taste to the water, but I disagree. There is a very strange taste in the water that is less tolerable than chlorine IMO. Minimum treatment time is 30 minutes for both.
Alternative: Boil water for 5 minutes at any desired quantity at virtually no cost! :)

It's impossible to tell if things like this work because if you don't get sick, you don't know if the water was infected or not. Nonetheless, on my last backpacking trip I planned on getting water from a stream that I saw on a map.

The stream ended up being extremely low, almost dry actually. The water was brown, almost completely still and very sketchy looking... I was pretty reluctant to drink it but I didn't have any other source of water for the trip.

I filled a 40oz container and added the pill. Waited 4 hours and drank the whole thing. Then got more water for the rest of the trip. I didn't get sick so it must have worked!

I purchased these 01/27/11 to store for emergency preparedness. The tablets I received expire 06/2014. Anyone looking for solutions that will store for a longer period of time may want to find another method of purification.

The product description had me at "30 tablets individually sealed in foil pouches". The iodine tablets tend to come in little jars that have an uncertain shelf life once opened. So, these 30 individual pouches are now dispersed amongst various packs, bins, and vehicles. Perfect.

The general rule is 1 gallon per person per day. That's 4 tabs per person per day of emergency, unless you can boil the stuff ...

At $2 per gallon, I wouldn't use these for purifying a lot of water if I had other options. For example, tossing a 7 gallon container of tap water into the truck gives me about the same amount of treated water as the 30 tablets could provide. Also, never underestimate the usefulness of a gallon of bleach.

We've used them in the Rocky Mountains...they work well.
Taste much better than the iodine-based purification tablets we used as kids in Scouting units.
We keep several packages in our emergency kits and food storage supplies, "just in case." Cheap insurance for the price. You gotta have clean, pure water to surive any disaster or emergency...these Katadyn MicroPur water purification tablets will give you that clean, pure water!
