I moved to a new house and found a 10" big blue water filter installed under the kitchen sink, of the type that would normally be whole-house. The water tastes off and I am assuming that the cartridge needs replacing, since it looks pretty filthy and I am fairly sure it has not been changed in several years.
I found these instructions for changing the cartridge. However, there seem to be a hundred types of replacement cartridges. I tried to look at various DIY and plumbing sites, but I still have no idea what type of cartridge is appropriate for filtering New York City tap water, or even whether this is a bad idea and I should replace the whole thing with a standard under-sink filter. Pleated? String? How many microns? Etc. It's all Greek to me, so any advice is greatly appreciated.

...you have some of the best tap water in the country. Either remove it completely, or possibly use a carbon filter cartridge if there's enough chlorine to bother you. If the filter looks off, the filter housing probably needs a good cleaning/sanitizing.
Which one (or how many) of the bottled water companies is just bottled NYC tap water?
