Should be more specific

What's the usage of the water filter?

Whole house? Drinking? That would help other sifus determine what's probably suitable for you

Landed? Get an outdoor filter for whole house, then a tabletop filter for direct-to-drink water 

If space and piping arrangements allows, you can consider getting a sediment / smaller filter, followed by general 5micron filter for your whole house.

Sediment > 3M AP902; for generally occasional backwashing + longer lasting duration between cartridge replacement

3M POE > 3M AP902; for budget abit, only replace 3M POE cartridges every 9 - 12 months if water from council dirty, 12 - 18 months if water from council ok. While your AP902 can replace every 18 - 24 months.

3M AP902 > 3M AP902; if budget constraints isn't a concern, but water supply from council is very bad - 1st AP902 replace every 12 months, 2nd AP902 every 24 months.

I am not expert in subscription based water filters or water filter brands, so other sifus may able to give further recommendations. Also take note of water pressure and existing water pumps installed, if any.

Just sharing my setup and those people around me that I have recommended them to. Planning to do lab testing for before and after water quality testing to see if its worthwhile sometime in future.
