Product review (4 stars): Worth the savings
These look like and install like the OEM part at substantial savings.

Two issues that seem to resolve themselves.  I had to waste twice the water recommended to rinse the filter after installation to eliminate the charcoal taste.  With an RO system feeding the waterline, filters are redundant, but necessary to operate the system.  My RO tankle only holds enough water to do 3/4 of a flush.  That means I had to return twice to flush the new filter.

The frig notification system designed to advise of a needed filter replacement didn't reset after installation or flushing the new filter.  I removed and reinstalled the same new filter 3 times before deciding to see if the system would resolve itself.  Somehow, this new filter and the LG refrigerator came to acceptable terms and the warning light went out.

Not quite the challenge of getting an HP printer to accept and quit threatening printer head damage for using refilled or off brand ink cartridges.

I will continue to use these filters.
