Our ice maker on the frig was leaking from the old filter. I went ahead and installed a new filter. This filter housing locked up from corrosion of months past. So 1 new housing with filter already $19.99. Culligan filter has plastic unit design, old filter had Culligan on its exterior brand to replace. Culligan No. 151196 matches HD-950 identically, polypropylene material is used inside Culligan unit housing. Cool drafts or hot drafts from frig will not change the units design.

Sediments will not enter into ice tray area or ice motor pump, taste on ice is always clean, odor filtration will cut some city water out that somtimes smells from processing.

Sometimes buyers have a budget, I will explain to you your choices and understand why you should buy the top cost. 5 micron cartridge, 25 micron cartridge, 50 micron cartridge. 50 micron removes all three areas, so buying just a 5 micron you only remove sediment, buying 50 micron removes sediment/taste/odor. Now you get the idea! You only need to unscrew the main plastic body unit to attain the filter part, I had to buy the whole unit because the unit ceased up.

Make sure the O ring is solid placed so you don't encounter water leaks, O rings are reuseable so don't throw the ring away everytime you replace filter. 40 GPM (gallons per minute) @ 60 PSI. Copper line installation require experience so you don't kink the copper lines. I have plastic pipes behind the frig allowing flexible play during disconnect. PLEASE REMEMBER ON THING BEFORE YOU START= TURN THE WATER OFF. I already made that mistake because I was in a rush.

Great product Culligan when changed filter is done every six months the filter length on uses. 5*****
