Bests & Worsts Reviews from Amazon

I unfortunately have accumulated about 8 of these thinking they would be better than the standard filters. Not sure if this first one is a dud but the Total Dissolved Solids stick I have for this has this filter doing zero incremental TDS removal vs what comes in from the tap. I was 108 coming in and 105 on the filtered side so basically nothing. The standard filters I have take my water (from a different floor) from around 102 to around 78-82 range. The water definitely is going through the filter and it is certainly slower than the standards but I am not seeing a reduction in tds at least on this first sample. edit - having had these for a while longer now, I will say, they have a funny plastic kind of taste to them vs the regular filters. I think they are all destined for the garbage. Am not going to buy these ever again.
