I ordered the wrong replacement filters online. The seller refunded me and told me not to bother shipping them back, so I have two replacement filters for the older (pre-2009) model Softub hot tub if anyone wants. If you are in Seattle, we can arrange in person pickup. If you live elsewhere, you can have them for the cost of shipping. Here's what they look like.
