I bought the more expensive Twin Air filter based on reputation. My expectations were high because of it being a Twin Air product. The filter itself is fine, but the clamp is junk. The clamp is too small in diameter and makes installation more difficult. The clamp is flimsy compared to the Loudmouth No Toil filter. For 7 to 8 dollars cheaper, I would stick with the No Toil filter and clamp. The No Toil set up is better and cheaper.
