With filtered tap water, water that we use for our aquariums, pets, and to water our plants is free from chlorine and fluoride which can cause harm over a long period of use. The thing is, if you don’t want it in your body, you wouldn’t want it in your pets or plants, either. Use of plastic water bottles, meanwhile, poses a great risk to our environment. About 60 million plastic water bottles are thrown out each day in the US alone; unfortunately, 80% of these are not recycled and just end up in landfills while millions end up as litters and pollute our oceans; thus, killing our marine animals.
Globally, we produce about 300 million tons of plastic waste every year; using filtered water means lesser plastic ending up in landfills and oceans to pollute the planet.
