One Way

Whats the proper way to clean one of those re-useable central air conditioning air filters?
I have one of those re-useable central air conditioner air filters (the ones that go under the air handlers)
I have been cleaning it out with my water hose every month or so.
Is this the proper way?
What happens if I place it back a little wet?
Using a vacuum cleaner prior to the hose makes it easier. A little damp won’t hurt anything.
