MH does have fans/filters/etc but I think the ACInfinity stuff is worth the money. I've not seen anyone complain about the MH ventilation prducts but they just look a hair too inexpensive for me. Plus I know the AC stuff is quiet and long lasting. I love the new controllers with the ability to set a constant "off" speed of 1 for air movement. The stepped transition speed increase is also a great feature. Their original 4" exhaust fan I bought is still going strong. Their filters are a weak point but the price is quite good. I had looked at TerraBloom also. I suspect a lot of them come from the same factory.
