I forgot this name like a filter for aircons or you can make a homemade net or a piece of paper which air can go though this paper should be fine that does not break or torn apart got this Idea from a posthere from bitcointalk.org too did not get the chance to save it if you understand my explanation when you buy a filter you put it on the exos of the miner. You dont need to clean a lot of you tried the idea that I got.

Sorry if wrong terms are used I am not officially a miner just want to know about miner step by step until I bought a miner for myself.

I got a problem linking the link here on bitcointalk.org so I would suggest search on Google aircoin filter and miner dust filter.
