I bought a clemco set-up years ago.. never checked the cartridge in the air purification chamber..... The good news, I can't blame any of The dumb shit I've done over The past years on it. But I did have a few refreshments talking about.. I should look at something I really could care Less about.... An I'm kinda glad I did.. So this is what I did. It may come with rite, Wrong if im here in a few years it worked... Anyway... I Pissed a lil zinc etching in the aluminum chamber that holds the charcoal canister in the air purification setup..... But!!!! Let it. Dry over heat before you Use.. I'm going to reuse after sitting on a controlled heat source. Just putting it out to guy's that blast.... Look in your air purification system before you start the season! Reason mentioning...... Mine had Lite corrosion..
