Will rainwater clog a misting system?

[CreatureTom]

As i'm soon going travelling and then to university (leaving my plants at home) i'm planning on setting up a misting system for my terrarium so my parents aren't burdened with spraying my plants twice a day. However as I use rainwater i'm wondering if it will clog/mineralise etc in the sprinkler heads. I know rain water is extremely soft but would the acidity have any impact? I'm thinking of buying this system: http://www.luckyreptile.com/products/145/en/pid1,3$pid2,3338$pid3,7773306/products.html

Thanks for any advice!

It won't clog it as long as all clog size particles are filtered out.
