Review on Tier1 Replacement FQSVF Undersink Filter: Efficient Water Filtration Solution by Jamie Richard

I ordered and replaced my GE equivalent with these stage 1 cartridges. On first use I had to run the filters for almost 30 minutes to rid the filter of its aftertaste (dissolve baking soda in water and you basically get what comes out of these filters). After cleaning, the taste was ok but not great and not neutral at all. After about three days, the amount of water started to slow down: the first use of each day is to brew coffee, so my tolerance for "slow" may have decreased. :-) Anyhow, I replaced them with GE units today - they're more expensive but work great. I would not recommend these filters.
