If you have an i1Pro 1 (Rev. A-D), you cannot remove the filter attachment without a high probability of breaking the mounting tabs (I have experience with this). The best you can do is to blow out the nose cone with a blower bulb (canned air might release its effluent into the nose).
The new i1Pro 2 (Rev E) does have a user replaceable measurement nose with a glass dust shield that can be cleaned. While you have the nose removed, clean the lens too (read the manual for the correct procedure).
If this does not improve your inter-instrument agreement, then you need to send the instruments back to X-Rite for recalibration or use a transfer standard and software, such as X-Rite’s XRGA system.
