Review: This filter was the perfect replacement for my Simpure reverse osmosis system. I noticed a HUGE difference after replacement in water pressure and quality. I could tell I was due for a full filter line replacement when my system started sounding a bit louder and angry when it would be filtering the water. I looked up multiple instructions and videos on how to properly change out the filters. All the information I found mentioned just unplugging the system and opening/running the tap out before undoing the filters. No where did it mention turning the water off which you HAVE to do to replace this PP filter as it is the first one that connects directly to the water input line. The other filters probably can be changed as long as the system is unplugged as the water will not be pumping through. I ended up with water all over my floor because I had not found this information. Review: SimPure T1-100 RO replacement cartridge installs easily and restores clean, great-tasting water.
