Hey, so I'm about to put my Transformers on mostly permanent display for the first time. I've order the cases with doors and what not, and they're on their way, so within the next few weeks for the first time, all my TFs will be somewhere other than bagged in storage bins in the closet. What took so long? Dust. My house has a serious problem with it due to the fact that when it was built, the builder cut a lot of corners because he was running out of money and used the money put down on this house to cover costs on another home he was building (yes he had his pants sued off and had to leave the state). One of the casualties of this has been the central air system... dust accumulates everywhere at an astonishing rate because the fllters have never worked right, so it just moves dusty air around. I've never displayed Transformers for more than a few day straight because of this. Well thats changing now with the cases, but I'm looking to do one better. I bought a HEPA-Type Air filter from Walmart. One nearly identical to this actually: Amazon.com: Holmes HAP706-U True HEPA Mini-Tower Allergen Remover: Home & Garden I'm wondering if anyone else uses these to control dust build up in their room. It's advertised as being able to filter air in a bedroom sized room very fast, so I'm hoping it surpresses the dust problem (which when combined with the cases I ordered, will keep my TFs in perfect condition). Is this something that has been successful with you? If not, what else do you think I can do to control the dust built up. Thank's a lot!
