COVE IS A new water filtration system for your home. On its own, this statement is about as exciting as buying a new filter for your Brita. But Cove doesn’t want to be your new Brita. It doesn’t want to be your new Soma, either. Cove it wants to be the smarter, higher-tech version of all those it-works-but-it’s-not-great water gadgets you’ve picked up at Target. Really, what Cove wants is to to be the Nest of the water filtration world, and it has the price to prove it. At $250, it isn’t the cheapest water filtration system you can buy, but it does have some thoughtful design touches that begin to justify the price hike.
