http://www.amazon.com/gp/product/B00IF7RCU6?keywords=3m%20half%20fa... This is what I went with. Since I wear glasses this should work fine. It has the quick latch system on it so I can flip it down when moving from tank to tank without taking it off. I got it and 2 sets of filters off ebay. Total cost was $28. I just went with the green ammonia filters. Didn't think I needed the dust cover.
