I've been using Invigorated water filters (bought the counter tank) since 2 years ago when I decided to give myself and family a better quality water. I can tell the difference between the chlorined (and all the other stuff you don't smell or taste that's in your tap water) and the filtered water we drink and cook with. Filters are easy to replace and I recycle the first 2 tanks of water after installing the new filter watering my plants or cleaning something at home. Win - win because I don't like to waste any drop. The countertop tank is easy to fill and lasts depending on the daily consumption (during pandemic been 4 here I had to refill the tank no more than 3 times a day only because we're heavy water drinkers) in regular days (when I'm mostly alone at home) once a day is enough. Definitely recommend this brand and products!
