Portable water bottle filter

Hubby bought a new portable water bottle filter for me. It's very convenient. It has a special Micro-Filtration filter that's capable of 99% reduction in contamination. This filter will last for 200 gallons or over 1,000 refills!! This will come in handy whenever we take the kids out shopping. I no longer have to buy filtered water. Can just top it up with tap water whenever it finishes.
