I saw it and got an in-depth demonstration at RAP Orlando. I can’t wait for it to come out. It will fit in a filter sock or has a bracket to hold it. You can block off the other inlets if desired so you don’t need to buy multiples but will need to replace your felt more often. It will work the same way as the rollermat just take up less room and hopefully not get weighted down like the rollermat does. I have a rollermat and one sock and will be replacing the sock with the Klir. I can’t wait!!!!!
