Lightest Water System so far...

For warmer wx use Im still very happy using my befree as primary, with tabs as backup. I did have a befree fail though, so I definitely think harder about a backup. I just started using aquamira drops and that may be my cold weather primary. may switch that into the mix for warmer wx as well, TBD.
 

The infectious dose of crypto is 10 cysts. Something to keep in mind.

I deal with disinfecting public water for work and have personally gotten giardia from "treated" water so I may be more neurotic than most.
So do you recommend a combo treatment? Please advise.

I have the sawyer bladder system, seems like I need to add a tab as well to cover viruses?
 
Everything I've read, even though you aren't addressing me specifically with your question, says the tablets are necessary with the types of filters we are talking about in order to get complete relief from bad things in the water.

You typically don’t find viruses in backcountry water. It would take an infected person to infect a water source and then you take water from that source. Highly unlikely to happen. Now if you were to take water coming in from Mexico say from that Tijuana cesspool of a river then absolutely chemically treat it 😵‍💫

Research your destination water source and decide from there how to deal with it. Many states have published info for that.
 
I carry the sawyer, the steripen, and the aqua mira tabs. Water filtration is critical for me, I like to have redundancy and flexibility. I use the steripen the most.

The Deer and Elk that spend the summer in the "pristine high country" spend the winter in the human and cattle polluted low country. The Bucks and Bulls like to use the highest water source too, its not uncommon to find a nasty mud puddle that smells like a corral where it bubbles out of the ground.

Read what the filter manufacturer states about its removal effectiveness.

For example the Hydra Pak filter cap. *Effectively removes common waterborne bacteria, such as E.coli (99.999%) and parasitic cysts (99.9999%) per HSF 42.

There’s no need to double up on disinfection process. Having a backup is always a good idea.

A filter/UV + tabs (iodine, etc) will kill/remove everything. The tabs are more important for killing bacteria than viruses for backcountry applications. Filter/UV is for parasites (giardia, crypto).
 
I do the befree on a 1 litre bladder and carry a 4 litre for dirty. Have two Nalgene’s I carry, one I use to mix. Backup is tablets, if I am worried I boil.

Since I have had kids and seen how much they swallow and get up their nose when swimming in rivers/lakes and not get sick I don’t worry as much.
 
It's basic surface-water treatment processes, and it still requires contact time to work. I'll stay with my current system.
I wonder if it's just a mix of alum and a chlorine dioxide type purification? Something like that if not exactly that.

Calcium Hypochlorite and likely alum.

I can't find the directions online but from youtube demos it sounds like:

- 5 minutes agitation
- 20 minutes wait time before consumption
- $2-3 to treat 2.5 gallons
 
What do you water wonks think about this stuff?



If the spec sheet is to be believed it's achieving 4-log disinfection, which is the equivalent to what is coming out of your tap. I don't know how you would set it up in the field tho. I may order some just to keep in my pack in case I need to drink some horrible looking shit water. Very cool product.

Instructions for Using P&G Purifier of Water​

Overview​

P&G Purifier of Water is a powdered treatment that purifies contaminated water. Each packet treats 10 liters of water and is effective in removing harmful microorganisms.

Step-by-Step Instructions​

  1. Prepare the Water
    • Fill a clean container with 10 liters of contaminated water.
  2. Add the Purifier
    • Open one packet of P&G Purifier of Water and add the powder to the water.
  3. Mix Thoroughly
    • Stir the mixture vigorously for about 5 minutes to ensure the powder dissolves completely.
  4. Let it Settle
    • Allow the water to sit undisturbed for 5 minutes. This allows the impurities to settle at the bottom.
  5. Filter the Water
    • After settling, filter the water through a clean cloth to remove the settled particles.
  6. Disinfect
    • Let the filtered water sit for an additional 20 minutes to ensure complete disinfection from chlorine.

Important Notes​

  • Do not use the purifier with soapy water, saltwater, or water contaminated with gasoline.
  • The treated water should be clear; if it remains discolored, repeat the process.
  • Always store treated water in clean, safe containers.
Following these steps will help ensure that the water is safe for drinking.
 
Puribag


I'd be a little concerned with the flocculant getting in the nozzle area. So, you would want to flush a bit of it before running it into your potable bottle.

I think you could prob just bring a clear gallon jug and then a 4 ft piece of clear hose and just do a siphon to a potable bottle as well.

I'm pretty curious about this product now. I definitely have uses for it.
