“Replaced the WD-D6RF Filter.
My first purchase from Amazon was returned because the box and filter package was not sealed completely or properly.
My second purchase was direct from Waterdrop, not that this makes any difference.
The original filter produced water 12 to 15ppm TDS. The new filter 6 to 10ppm TDS.
This does result in reduce water flow rate and requires a longer time to fill a bottle. Not sure what the difference is between the GE filters, maybe normal variation in the osmosis filter pore size.
Waterdrop needs security seals on the boxes, so the customer clearly knows that the filter is new and not used.”
