Bests & Worsts Reviews from Amazon

The Whirlpool EDR3RXD1 filter did NOT (work) filter water. I bought filter from Amazon on 2020-04-04. I install filter on Whirlpool ED5FHEXV502 fridge. I run 4 gallons of water through filter to set filter into working mode. I set up three glasses of water (see photos). I let glasses of water sit on a table for 1 hour to come to room temperature. Then I used TDS Meter tool to measure the TDS (Total Dissolved Solids) of water in PPM (Parts Per Million) units. Glass #1 contains filtered water from the fridge where Whirlpool EDR3RXD1 filter is installed; PPM reading of 255 Glass #2 contains purified water from purified bottled water; PPM reading of 4 Glass #3 contains un-filterd water from kitchen faucet; PPM reading of 256 *** Result: Water from Whirlpool filter have *same reading as kitchen faucet water; meaning Whirlpool filter did *NOT filter the water
