That's exactly what I did last year :-) A stand alone sediment filter where I turn two valves to reverse the flow of water. It's not very aesthetic and it takes more space but it does make my life easy. Regarding your 2nd point, most of the cartridges use a "Welded Housing" and carry the "Dow Filmtec" brand. However there are sellers on ebay that supply housing that can be opened and you can fill your own filter material. I'm a little skeptical on taking this route without an understanding or testing ability of what effect it would have on drinking water. I wonder if there's an off-the-shelf complete water test kit or a lab that would do that for me.

Cool! Would you be willing to share photos or details of your setup? Or point me to a similar one? I live in Taiwan and currently get drinking water from fill-up stations outside due to heavy minerals in the groundwater here. It's not too inconvenient to do it once a week or so, and the water stations are ubiquitous, but I miss having drinking water from the tap. I've visited water filter shops 2-3 times with the intent of buying a filtration system but am put off by the cost of replacement filters which I know I will have to buy frequently. I'm being cheap but the engineer in me keeps saying there's a better way. Also, I was not able to figure out how I can test the water quality without sending it to a lab in the US. Do you test your own water?

  The extra only saves the trouble of cleaning the main filter too frequently. The cost of filters, especially the RO membrane (the most expensive component) that removes dissolved impurities would still be there. The advantage of my setup would be to prevent RO membrane from getting clogged too early by sediments. The additional filter would look something like this [1]. It's an inline sediment filter with a separate casing. For the rest of the unit, you might still be able to buy a complete kit off ebay e.g. [2] & assemble it yourself [3].
