Hello, No the filters are not heated and nor is the tank. In our area it is not a concern. If we were traveling in an area where that would be of concern, additives to the tank like you currently do would be what I would do also.
Carving up something from a large block of foam should be a snap I think that would slide over the two filters and strap up. The other thing I would think of is something along the lines of heat tape and a special control system but the tank would be my biggest concern.
Hope that helped a bit.
Cheers.
