And considering that water is so much heavier than air, the air will be sucked in much more easily than the water. Plus, if you are driving through a puddle, you would (should) be going slow and at a low engine RPM which means low blower speed which means not a ton of flow through the filter. The less flow, the less likely the heavy water will be picked up. With that said, I would be more comfortable w/ a filter that is a bit higher off the road. Just my 2c.
