Sawyer finally realised that other companies were providing adaptors to turn this squeeze filters into gravity filters and so they produced their own. If you want a gravity system that will fill your bottles at your campsite that can double as a squeeze system for a quick “give me my water now” refill on the road then this is your ideal product. They’re great for setting up at your campsite and just leaving them do their own thing but because they take more time they’re less good for that quick stop by a stream to refill your water bottles. Gravity filters take away all the hard pumping and squeezing and instead with gravity filters water flows from a top bag through the filter into a bottom bag. These can be either built in or come as a syringe, and extra item to carry. Some filters try to send it back out the way it came with a back-flush. Purifiers come in many forms, chemical, UV light and super-fine filters being the most common all of which have their pros and cons.Īll the microscopic stuff you’re cleaning out of your water is slowly blocking the microscopic pores in your filter, and that means filtration gets slower and harder. If you do want to stop viruses then you need a purifier. The good news is that 99% of the bad stuff in water are amoeba and bacteria so usually that’s enough.
The basic fact is that there are big micro bugs like Amoeba and Bacteria that are relatively easy to filter out but viruses are just so small that it’s a technological challenge to filter them out, not even the best camping water filter will catch them.
The filter itself does most of the work and gets most, but unfortunately not all, microscopic life out of your water. (as Amazon Associates we earn commission from qualifying purchases) Water Filters VS Water Purifiers
