Riccardo Zennaro, coordinator for the UN’s Global Wastewater Initiative, previously told HuffPost that in the event of flood, you might not know whether your water has been contaminated by sewage or chemicals. Most likely, however, it’s been contaminated by both. In this case, he recommends passive gravity water filtering systems to get the cleanest and safest water possible.

This gravity fed water system, like all gravity systems, requires no electricity or running water to work. It has a capacity over 2 gallons and uses the process of reverse osmosis, in addition to two carbon filters, to effectively filter out a number of impurities.

Promising review: “I have to say that I always thought my tap water was excellent, the town does a great job of flushing and testing, so I wasn’t really expecting too much of a difference. I have read a lot about water filtration and figured I’d give it a try. I’m so happy I did, the water tastes amazing. The system is really easy to set up and use. The tank is a bit large, so you need to have enough counter space, but I like the look of it in my kitchen. I’d definitely recommend it as a low price option.” —Patrick Bellavance
