While boiling will pretty much kill everything in the water, as of right now the kritters you have to worry about in US waters tend to be bacteria sized and larger. Most filters will handle those kritters. If you were going over seas, invest in a purifying filter to catch the viruses as well.
Any reason you have picked that filter over others? I carry a MSR MiniWorks II. It is easy to pump, easy to clean and I can use it one handed.
Google and check out GrapeFruit Seed Extract for adding to water to make it safe to drink.
If you are going to boil anyway why pay good money for a filter?Quote:

Hey, Mr. Survival Instructor. News flash, viruses are smaller than bacteria and are in our waters, too. I'm gonna have to go behind him and pick up dead students. This is gonna be a chore.
If you are going to boil the water anyway why spend the money on a filter? If you're going to spend the money on a filter then carry a small amount of bleach. The filter will stop bacteria and parasites and the bleach will kill viruses.
Don't depend on the bleach alone to disinfect water because it doesn't kill Cryptosporidium or other coccidian parasites.
EDIT: I was typing when KY posted. Great minds and all.
I watched D. Canterbury do a review on this the other day.
From what I understand it does catch chemicals.But crypto,gardia and hep can still get through.
Especially the cyst?
I'd like to run some water through this filter and check it with the TDS meter I use for my ro/di water filter.
See what the numbers show.Maybe get some "cool guy"points here from some of the gurus.:w00t:
Before we get into the required explaination of virus size, filter mesh size and what germs do what to us why not just ask yourself this:
Does it take out as much as my local utilities filter out?
I have come to the conclusion that most of us expect our emergency/woodcraft filters to give us better water than we drink from out taps on a daily basis.
Most local utilities use a fast sand filter and chlorine generated on site. I have met some of the guys that work at the water plant and believe me, it is not rocket science or they would kill us all.
Run it through a filter, dump in a few drops of bleach and drink it. I have missionary friends that are doing that in some of the worst imaginable parts of the world and are staying healthy.
Not according to their web page. It filters 99.9%. I'm familiar with their Frontier water filter but not the one you asked about.
The reason it can remove some chemicals is because it contains activated carbon. It adsorbs with organic chemicals like phenols, nitrites, nitrates and ethers (there's a lot more). But it won't stop heavy metals.
There exists a .02 micron filter that filters out viruses. My filter is .1 microns.
Then you have Bear Grylls drinkin pee out of a dead snake skin, and he dont even die! He must be like Chuck Norris huh:smartass:
Yeah,but he did have the squirts once while in a precarious position climbing a waterfall.Quote:

LLT - Shoot Aquamira an email or give them a call and ask what the pore size is. I'm sure they will tell you. I'm also sure it won't filter viruses. I'll be surprised if it does, anyway.
Just strain it through your bandana and then boil it, save your hard earned cash.
The reason their website says it filters 99.9% is if somebody gets sick, they can say it was the 1/10 th of 1% that got them, CYA. lol
I guess it depends on where you're at, but neither boiling nor filters catch everything, using both therefore is ideal. This is a great video on the subject.Quote:

Boiling water is the preferred method of purification. It will kill all pathogens including viruses.
Filtering water with a commercial filter will block all pathogens except viruses.
I'm not sure why you think neither will catch everything. I would not boil my water if I used a filter and I would not filter my water if I boiled it. It's redundant and a waste of time and fuel.
Potable is pronounced like pōtəbəl not pot able.
I hear a lot of people pronounce it like pot and able put together like Dave says it. I learned the word from Jeopardy years ago as the category "potent potables".
How do you pronounce the word?
Check out video I posted above you, he explains why neither catch everything and why using both is ideal and absolutely not redundant.Quote:

Unless your filter has activated carbon it will NOT remove any chemicals from the water. If it does then it will aDsorb only organic based compounds. It does not filter them it actually becomes chemically bonded with the organic based chemicals. That's what aDsorb means. Most of those fall into the Volatile Organic Compounds term. Things like chlorine, benzene, radon, etc.
They do NOT adsorb inorganic compounds such as arsenic, nitrates, mercury, etc. Those are heavy metals and you cannot remove them with any method that you would carry to the field.
While an argument can be made that all water contains some levels of both organic and inorganic compounds if you suspect your water is contaminated (road side ditch, industrial plants nearby, etc) then you need to find another water source.
I stand by my answer. Filtering and boiling are redundant.
I wanted to come back to this and offer a clarification. I wasn't considering a larger pore filter, which the Frontier Pro could be and this thread was based on. Someone PM'd me and quizzed me about the larger sized pore vis-a-vis (I really just wanted to use that word) my comment about boiling and filtering being redundant. Thank you for the reality check by the way! Aquamira does not mention the pore size in any of their adverts but they do say it will kill 99% so it's possible the filter is in the .03 micron range. I just don't know for certain. I guess it depends on how they do their math.
If you have a filter that is in the .3 (not .03), which many emergency filters are then it is not stopping all of the bad guys. In which case, you will need to boil your water or chemically treat it. I'm of the opinion that if you are going to boil as an adjunct to filtering then you might as well boil to begin with. If you are going to filter in the .3 range then you need to have a chemical follow up. There are some advantages to filtering at the .3 range. Turbidity, adsorption of some chemicals if the filter is equipped with activated carbon and debris can all be avoided with that size of filter.
Even at .03 you will not filter out viruses so chemically treating the water is still advisable.
If you are going to boil and have the option then filtering is not necessary. If your filter is larger than .03 microns then something besides the filter needs to be added, either chemicals or boiling. But if you are going to boil why not do it in the first place?
I hope that clears up any confusion I might have created.
My thought exactly.Quote:

You can also try just letting things settle out for a while, but some things either won't settle or will get all stirred up again with the slightest motion.
For many years I carried a couple of large commercial coffee filters in a well-folded gallon-sized baggie, and attached to the outside of my canteen cup with a large rubber band. I also had one of those canteen-cup "stoves," and a small pair of water-pump pliers stashed in the canteen cover. (1) Put a coffee filter inside the "stove" - leaving plenty of droop, then attach it 'round the top with the rubber band. (2) Insert the assembly into the top of the baggie, holding top of bag around the assembly with your hand. (3) Pour the water through the filter, slowly enough that it doesn't overflow or tear the filter. Once the bag is nearly filled, you're all set to make it safe to drink.
This worked great, and a fair amount better than a bandanna, do-rag, etc. The filters were also fairly useful to help start fires - as long as they weren't wet, of course!
But the comparison was commercial filters vs. boiling.
If that was to me, I was trying to add something to both "sides" of the question. Both benefit from a good pre-filtering to remove particulate matter and a lot of silt. My approach goes a good bit beyond straining the water thru a bandanna or do-rag. I did this whether I planned to boil the water, treat it with chemicals, or use a commercial filter.Quote:

Now, if my earlier post contributed confusion rather than a suggestion, my apologies.

No, no. My confusion is eternal. And trust me, a lot of folks have offered me suggestions. Most of which we can't discuss here.
Are you sure we aren't related? :blushing:Quote:

I would hope someone misplaced a decimal. You can drive a truck through 3.0 micron.
I just checked the current price for a First Need filter. As the Russian once said, "Holy Sh*tskies!" They are -- um -- quite a bit more expensive than they were when I was using them. Wow, am I EVER glad to have a new (unused) one, and two replacement cartridges, in my equipment!
(I mean, I'd absolutely hate to be required to float a loan just so I could afford one... :blushing: :3: )
