The Hydro Photon Water Bottle Pre-Filter is just what it says—a pre-purification screen system for larger particles that screws right onto your water bottle. The Hydro Photon SteriPEN is a magical miracle of water purifying technology, but alas, while it kills the baddies you can't see, it won't make the dead bug floating in your water bottle disappear. That's where the Pre-Filter comes in, filtering out anything bigger than 17 microns and making the water you're about to zap with ultraviolet radiation clear before it's clean.
Bottom Line:Because you'd rather drink water you can see through—the Water Bottle Pre-Filter.
When clear water is not available, use the Water Bottle Pre-Filter by SteriPEN. The Pre-Filter filters out particulates and debris. Fits on Nalgene® & wide-mouth water bottles.

Nescessary for filtering! | |

Just because you have a Steripen doesnt mean you will have clean-debris free water. This filter is essential, in fact it should come with the Steripen standard (that crucial). It screws on top of your wide mouth Nalgene bottle as you dip it into a stream lake etc... and the nasty silt sand etc... get stuck outside the filter and not inside the water you are about to zap with UVC light. Then as the water bottle is filled with untreated water pull out the mouthpiece portion while leaving the filter screwed into the Nalgene and add the Steripen then turn the Nalgene upside down and rotate for 90 seconds and blam fresh water without debris and killed microorganisms. The one thing this and the Steripen do not do is eliminate color from the water. So hopefully that dosent bother you, but most streams and lakes you get pretty clear water anyway. | |

Boundary Waters must-have | |
| Rating: |  |
Friend and I used this for a week long trip to the Boundary Waters. I didn't know before hand that my generic-brand Lexan bottle wouldn't have the same threads on this screw-cap prefilter. Luckily my friend had a Nalgene bottle, and we had no problems. It filtered out debris, but not the color of the water. Not a problem for us, but beware to those who have a problem believing brown water is safe to drink after you've used the pre-filter with the Steri-Pen. | |

I used this on a river kayak camping trip with a group of friends. It works great, attached perfectly to an old water bottle that I use. | |

| Took this pre-filter with me on a 3 day trip to Shenandoah. Worked pretty well on keeping out the majority of debris. Fills fast using submersion or pour through methods. Very lightweight but still a little hard to find a spot for in my pack due to its chunky design. | |

| The prefilter works well and stores easily on a nalgene bottle. It's helpfull to have an extra bottle handy to pour the unfiltered water into the empty one with the filter, because it takes a long time to fill holding the bottle in the water. | |
