How to reduce system noise to below 50uV for AD8233

We use two electrode AC leads off detection for circuit configuration and using two-pole, high-pass filter, and two-pole, low-pass filter.    (Frequency response range is 0.05hz to 40Hz)

Measuring the system noise that is around 100uV(clause IEC 60601-2-47 system noise < 50uV).

Does someone help us to reduce system noise ?

The picture is our design value.


We would like to use AD8233 to pass IEC 60601-2-47 system noise < 50uV.
