Review on Waterwise 4000 Post Filter Replacement by Sean Tops

I have not used the distillery without a filter. I put a tick on the wall and for my area here in Florida I can get about 70-75 gallons out of a filter before noticing any deterioration in water quality. I have recommended this product to others and they change their filters by marking the calendar every month or every other month. I drink an average of 3-4 gallons a day because I'm a dog breeder and that's what they drink, so I use the ticks on paper method to get the most out of the filter. The dogs report when they don't like the water anymore and I change the filter. I can get a box of filters that will last about 10 months, give or take.
