The 200 mesh filter is what is recommended and they are relatively cheap.
The filters can be back flushed to clean them out also.
Here is a link to some filters you may be interested in.
Sadly they dont have one for chlorine.
I do suspect that the bodies would accept a chlorine filter if you looked around or took measurements.
Most of this stuff is standard sizes anyway.
Dont freak out the prices range from expensive to affordable.
