    Very happy with our new filter, for many many years i’d pay a weekly visit to my local water store to have clean water for myself & family- this big filter allows for us to have that same convenience without having to do the driving. Very grateful.

    I just received my water filter. I love it! It had a dent when received, I notified customer service and received a new piece to replace the tented section with no hassle! I’m very happy that I do not have to spend so much money on bottled water. I love the chrome look as well!

    We just moved to an area with a dangerous level of contaminants. So happy to have our ProOne filter to keep our family healthy! Perfect size for a family of 4!

    I received the Big Gravity filter in early August… After a quick assembly and installation of the 3 7-inch filters, I quickly loaded it up… In a short time, I had filtered drinking water… I have researched in this particular industry and settled on Big One as the best option… My effort has been proven… So much so that, I am buying a second one for my RV.

    So far so good. The filter works well and the water tastes great.

    Love our Big Gravity Filter! We have owned it for about 5-6 years and it continues to deliver great tasting water.

    Five kids family of seven and we love this water filter. I thought I’d have to fill it more than I do, but I can almost go 2 days without filling it. I do end up adding some water to it every night just to make sure. The water tastes great.

    Literally the best decision I’ve ever made. If I drink water out of anything other than this now, you can clearly taste chemicals
