IMO, here's the big deal about Ramair's filter: as long as it's being made no other mfg will enter the market with a high performance R3 filter because the market isn't big enough for more than one. That's why I want to know, and why I want everybody else to know, whether this filter is the real deal. If it's not, I want it to go out of production so another mfg will give it a go. If it is the real deal I want to buy one and support Ramair so it will stay in production. All I'm asking is that Ramair live up to its published assurance about revealing testing results. I don't think that's asking too much considering how cheap and simple it would be for Ramair to do. I think we should all be demanding that Ramair back up its marketing claims.
