Product review (5 stars): No problem at all!
I bought these to replace my GE MWF filters. The reviews here are quite extreme, some people are very happy with these yet some had horrible experience. I had no problem installing mine. The key is to push up the filter THEN keep turning it clockwise until it won't turn anymore. Honestly I'm not sure why some people had trouble with these. I'm a happy customer and will continue to buy these replacement filters.
