There is no filter, this smell is caused by mold/mildew in the system from normal condensation from the AC evaporator core, you can try Lysol, spray at the air intake in front of the windshield for about 20 seconds, turn of the system and let it set overnight, this will cure the problem for a few months, then you will have to treat it again, as the mold will regrow in the moist environment of the AC air distribution box.

Are you sure the smell comes from the washer water and not the air conditioner? If the washer water smells you will smell it strongest on the windscreen on the outside of the car. Check this to be sure you have located the source of the smell.

Commonly smells inside the car come from the air conditioner because there is mould growing on the air filters. These can be taken out and cleaned to get rid of the smell. Look in your user manual for guidance on how to do it.
