I have used portable filters in the past for camping. I bought the drip filter for my home as we are on a spring system that is old. The filter gives us confidence we won't get stray bacteria or parasites in our drinking water.
The drip filter is very easy to set up and very easy to use. The only moving part is the spigot.
My only question is the life of the filters. The specs say each filter is good for 30,000 gallons of water, but another note says the filters are only good for 3 years. That would equal 27 gallons per day. Why would the filters have a life of only 3 years?
