  1. Uncap the highest 
  2. Place the inlet backside portion of the Survival Spring in your supply water for ten seconds. 
  3. Take 5-7 quickdraws from the mouthpiece to carry the water up and thru the straw. 


I made a decision to try to prime the filter inside with common outdated faucet water. 

Now, the world by which I reside doesn’t have significantly good tasting faucet water so I believed this is able to be a superb place to start out and it could assist me to turn into accustomed to the filter. 

I grabbed a glass and crammed it up with water from a toilet faucet.

 Since this was faucet water, I wasn’t going to have the ability to see any distinction within the readability of the water from utilizing the filter, my residence water just isn’t that dangerous.

But I used to be curious if there can be a distinction within the style or odor.

After filling the glass up I adopted the directions and allowed the massive finish of the filter to relaxation within the water for ten seconds. 

I then took 5 quickdraws, pulling water up and thru the filter.

The first preliminary attracts had been tough. It was much like sucking by means of a plastic straw with a bit of ice clogging the tip. 

But after a couple of extra pulls on the mouthpiece, I may really feel the water being drawn up by means of the filter.

Once the water was popping out of the mouthpiece, I spit the primary couple of mouthfuls out. Sometimes there may be residue left on water filters and it’s good follow to discard what first comes out. 


I took one other lengthy draw and bought a mouthful of water, which I swished round for multiple seconds earlier than once more spitting it out. 

The water not tasted like my faucet water, which is usually a good factor, however as a substitute had an odd plastic style to it. 

I believed this was perhaps as a result of filter being new and determined to take 4 extra attracts from the mouthpiece. 

Each time I spit the water and will detect that odd style. The greatest means I can describe it could be like licking a disposable plastic cup.

i’m not certain if this style is regular, contributed to the filter being new, or just isn’t regular and mustn’t style that means. 

I didn’t just like the style that was produced. However, if that style is regular for the filter I may reside with it when water have to be filtered.

Using It

As I discussed above, the primary couple of attracts may be tough even after the filter has been primed. 

But as soon as the whole lot contained in the filter is saturated it’s fairly simple to drink and pull water out. 

Cleaning It

It is beneficial to wash the filter after each use and to permit it to fully dry out. 

To wash it, merely blow filtered water by means of the mouthpiece till the water come out of the underside finish turns clear. 

To dry it out, the filter may be given a couple of shakes to shortly discharge extra water and the cap ought to be let off to additional velocity drying time.

Survival Spring vs Lifestraw

They are additionally extremely comparable by way of weight and operation. 

From what I may discover the within of a Lifestraw consists of hole membrane thing like stage 2 of the Survival Spring filter. But the addition of a carbon filter in stage Three of the Survival Spring provides it a leg up.

However, based mostly on the specs the Lifestraw can produce greater than double the quantity of drinkable water.

The Sawyer Mini is the winner over the opposite two choices. It can be utilized immediately from a water supply, threaded onto commonplace water or soda bottles, and may hook up with inline water packs.
