Very easy to set up and use. Would recommend rinsing filter or letting some water run through it before using it. Water tastes great coming out of it after. ### ⭐⭐⭐⭐⭐ Clean Water *by S***. on March 9, 2026* I bought this as a gift for my son that loves hiking and camping. He has enjoyed this product very much. He has carried it on many hikes and camping trips. Uses it for fresh drinking water and if cooking something over a campfire. I would recommend this product and I would purchase again. ### ⭐⭐⭐⭐⭐ Great Setup! *by R***H on September 26, 2025* While I've not actually been able to test the flow rate of this filter in a gravity configuration, it works exceptionally well with smart water bottles. It filters the water well to make it more clear, it tastes good, and I've not gotten sick even though I've had some very mild immune responses; like one may experience after some vaccinations. From what I understand, this is just my body responding to trace amounts of bacteria which may still get into my clean water from cross contaminating it with dirty hands, and results in resistances to local bacteria. Not unlike how seasonal allergies may be less likely to significantly affect local populations who grew up with those allergens. The instructions are clear and easy to follow, but this whole setup is so intuitive I didn't need them anyway. I like how compact this kit is, rolling up nicely in it's bag, and the wide mouth of the flexible collection bag is very useful for scooping water out of places where a bottle cannot reach it. The system does not seem to leak, and I feel safe drinking the water it filters from running sources. But I still prefer to purify the filtered water I collect from standing sources with some Aquatabs, just in case of pet waste on the trails, or dirty shoes walking through the mud. ## Frequently Bought Together - Membrane Solutions Gravity Water Filter Pro 6L, 0.1-Micron Versatile Water Filter Survival with Adjustable Tree Strap, Storage Bag, Survival Gear and Equipment for Group Camping Emergency Preparedness - 5 High-Capacity Emergency Water Straws – Lightweight, Reusable, 1800-gallon Filters for Camping, Hiking, Travel, Biking, Survival, and Emergencies.
