This prefilter attaches to the end of a SweetWater inlet hose to prolong the life of the water filter.

  • Removes 5 - 10 micron particles before they reach the main filter
  • SiltStopper is more porous than a SweetWater filter and may clog sooner—prefilter replacements sold separately
  • Attach the SiltStopper such that the red side filters the incoming water

Must-have accessory for the Sweetwater

Rating:*****
Since even the clearest lakes can have an alarming amount of particulate matter, this really extends the life of your Sweetwater pump filter. Plus, you will not have to clean your ceramic filter as much in the backcountry.

I have even found that I can 'clean' the paper filter a couple of times before I replace it with a new filter tube. While the filter paper is wet, I gently rub the outer layer of paper off. This discards the clogged outer shell and exposes a fresh surface. It is perfectly safe since this is only the pre-filter.

Works Great with Other Brands

While I still have my Sweetwater, I use this pre-filter with a Katadyn Hiker Pro. It should work with other brands as well. I am amazed how much algae can be in water that looks perfectly clear.

Good first line of defense

Rating:*****
It seems to work well (it turns brown and you replace it, since it is not meant to be cleaned). Disposal is the only issue. Carry soe extras, since it will turn brown quickly in some coditions.

great to save your filter

Rating:****
Great to save your main filter. You can reverse the filter inlet & outlet and discharge to quickly field clean the filter. Abuse this little guy and save your more expensive main filter!

works, but split during cleaning

Rating:***
I just bought this as a pre-filter to my sweetwater that is over 20 years old. It definitely catches algae as the outer part quickly turned an olive green while the inner part remained white. It has a small surface area so it clogs rather quickly, but I suggest that you just buy extra filters rather than trying to clean it. When mine clogged the pump could still provide enough suction to evaporate (boil) the water through the silt stopper, but it was a very slow process to filter water. When clogged it took over 15 minutes to fill a Nalgene that normal took less than 3 minutes.
The instructions say to connect the silt stopper in reverse on the filter output to clean it, but that just caused the silt stopper cartridge to split in half making it worthless. Anyway now that I own the housing, I’ll just make sure to buy enough cartridges so I won’t have to bother cleaning them.
