Product review (1 stars): This brand of filter is very unreliable
This product is a total crapshoot. Or maybe just crap. I had one of these filters that worked for a few months, then stopped allowing water to flow through it. I ordered a replacement and the new filter did not work at all. Fortunately, Amazon refunded my money and I bought a different brand. I will not go back to the Waterdrop. Too much time wasted.
