Good price and well built
I bought these because of a recommendation. I have not used them as of yet. They appear to be made well and come with a good rating from other customers. They are portable with a fair price point and can last over extended use.
Amazon Customer –
A necessity for hiking, camping, emergencies and a “Go-Bag”.
Have not actually used. Ratings indicate a good product. We have them on-hand in case of need.

Cheap insurance
These were cheap enough to just throw one in every vehicle and 4-wheeler. You never know when you might need one.

Quality
These are one of the best quality emergency water filters on the market. They work great. I’m giving some as gifts for Christmas to some of my hikers friends & some for auto emergency kits.

Water membrane.
The order was delivered as expected. I did not use it jet though I am satisfied with this order and hope it will perform as described.
Jeff –
Honestly a MUST have item for every go bag and camping pack you own! extremely compact and lightweight and a lifesaver if you ever need it. Used one once to test the product and have zero concerns that it will work as well again.
Giovanni –
Articolo come descritto. Forse un po’ complicato aspirare acqua ma inserito in una bottiglia di plastica si può filtrare più facilmente.
Jorge –
