Product review (1 stars): Not nearly as good as the OEM filters
We tried one of these filters, following the instructions completely and then making additional efforts at the vendor's request. ("Soak the filter overnight in warm water", or "run 3 gallons of warm water through it") and the filter still did not filter better than the 10+ month filter we were seeking to replace.  Plus, the water pressure of the new filter was about half the strength of the old filter.

The description in Amazon for these filters claims these filters do more than the filter packaging claims. These filters do not appear to be officially certified against NSF standards 42 and 53 - I'm not sure they're officially certified at all.

I sent mine back after a bunch of wasted time and effort. For an extra $15 or so, I got the real deal, which also is certified to filter 5 common pharmaceuticals.

I believe this product is cheaper because it's inferior. My total dissolved solids tested actual detected an increase (more impurities) when I used the EcoAqua filter, which recently changed names from Supco.  Check out those reviews and you'll see why they re-branded this.

They fooled me enough to get me to buy it, but not enough to get me to keep it.

If you don't care about drinking impurities, you'd be better off just changing the GE filters less often or not at all.
