I bought an Magnum H.O.T. with an extra micron filter. The H.O.T broke within a week and I returned it. Therefore I was left with two filters. I used one for a few days and then cleaned it as per the instructions, soaked in bleach over night. Then I used the other filter while it was soaking. Therefore I have two very slightly used filters. $8 shipped.
