Product review (5 stars): Fit my Samsung refrigerator like the manufacturer filter
Fit my Samsung refrigerator like the manufacturer filter.  Pure H2O PH21300 advertised it fit, however I found it would have had to have modifications or unusual (and uncomfortable) force to get it to install, which the vendor I bought it from suggested I do.  When I asked if they would pay for replacing the filter receptacle in my refrigerator if it broke from following their advice, they were silent.  BTW, I had ordered the EcoAqua filter from them - they substituted the Pure H2O since they were no longer carrying the EcoAqua.
