First off, I'm using this in a GE system that was purchased from Home Depot. Since Home Depot periodically changes vendors (well, every few years if that), sometimes you get blindsided by a product with replacement parts no longer being locally available. Additionally I like many felt that these parts were way too expensive to pay year over year the replacement cost. What I found out over time however leads me back to factory parts like this...
Companies like GE that sell these parts have a long term reputation to maintain. Therefore they don't necessary "skimp" on parts where quality plays a huge factor. On the other hand, they also charge an arm and a leg for these quality items. For home users, its about finding a happy medium.
There are two filters in the GE reverse osmosis system, this one and then two others of a different type. This one is the "expensive" filter whereas the other two are much less expensive. In looking at reviews, working with HD and their water quality free testing kits, and just generally trying to "taste test" some of the important things I've found include... Don't skimp on this one particular filter. If you are going to go for a lesser quality item, do that with the other two filters, not this one. This is not like your normal "screening"filter. Rather, this one has pressure push the water through a series of membranes and the water that gets all the way through is your drinking water whereas the items that skim on the membrane are pushed out the other side of this filter and later "dumped" down the drain. (this isn't completely accurate but give a general idea). This particular filter has more functionality and ultimately is the end of the line where your final filtration happens. This is why its an unusual cartridge with an O-Ring on the outside of the canister (this is very important along with the diameter of the cartridge itself for correct usage). I've had the cheaper versions that you see here on Amazon either leak, have bad seals, not actually use the membrane in the correct manner, etc. And the tests of water quality that I've gotten back reflect the cheaper filters do (over time) a much worse job. Testing right after you get them is a little unfair as they tend to work at first.
Anyway, like I mentioned before, if you want to shop for cheaper filters, do it with the rest of the filters in your system, not this one.
Our city water is pretty nasty. It meets the required inspection values, but those ranges for passing are pretty wide. Yep, I won't die from the water, but I do have rings around tubs and it has a different taste to it. What I've done overall to the house was to first install a whole house filter. This is where I'm the cheapest with EBay filters. Enough to get the nasty stuff out. Our water is bad enough I'm changing this one every 3 months and what I pull out looks like slick rust on the filter. We then added a water softener to pull out the hard minerals that get through our whole house filter. This eliminated most of the rings around our showers and toilets. Lastly our cooking and drinking water are off of the GE reverse osmosis filter. We installed a separate water faucet in the sink for filtered water and T'd off the connection to the refrigerator water line. This allowed us to replace the refrigerator filter with a blank and not have to constantly replace that as well.
