Product review (5 stars): GREAT filter
i have a propur nomad expanded with 2 (pro one)filters. i have used brita, pur and zero water filters, this is WAY better than any of these. it takes about 4 hours to filter the 2.25 gallon capacity, but knowing my kids aren't drinking fluoride is well worth the wait.

1) they recommend 2 cycles before you drink the water. i would say 3 or 4 is better as the water tastes a bit strange at first.
2) at first the filtration (pro one filters) is slow, but it gets WAY better through use.
3) installing the nozzle is a bit of a pain, nothing too bad, but i don't have a ratchet set.
4) have a pitcher to keep in the fridge, that way, when you drain the contents, you can immediately refill without having to wait for water later.

i REALLY like this product. i would highly recommend it to anyone that wants clean drinking water. it really tastes better than even high priced bottled water, plus there isn't the environmental impact of plastic waste.
