Magnetic filter and cleaning solutions

Hi I’m hoping to fit two towel rails soon. I have a bm2000 linked to an ideal classic ff370. As I’m doing this an draining the system down I thought it might be wise to do a system clean and fit a magnetic filter. Any recommendations on the best cleaning/ inhibitor solutions., any recommendations on magnetic filter also where has everyone fitted theirs. Thanks for any advice.

Any filter needs to be fitted to the return to the boiler.
In line Y filters can be good also.

Weekly
Then monthly
Then once a year.

Just checked above my boiler and don’t think it’s possible to fit one the pipe Work is minimal so going to get a load of cleaner, descaler, leak sealer and inhibitor and treat the system that way instead.
