Input:
Question: 1 Quart =  How many liters of water ?
Document: Such a shame because the mountain water is absolutely divine tasting, and with aquatabs I could enjoy that without the risk of getting sick. I'd recommend these to anyone and will absolutely use them again myself.
Used these while hiking in Nepal (Everest Base Camp trek), as did several other friends hiking with me. None of us had any stomach issues, even though the water at times definitely had sediment in it (that we didn't see, so we weren't even following the &#34;dirty water&#34; instructions).
Answer: no
