If thats the case then no type of filter will help you! You will be fine they are very resilient and designed to filter anything. Think of it this way even if you got it soaked its only a prefilter, your main filter is tucked away safely behind it. If you did get it soaked and fired up the motor then if it was blocked with water the air flow would increase through the snorkel or top of the air box instead of the stage 2.
