Hi,
Thank you for your report, the ZOOfilter plugin is currently not supported by our Zoo extension for JoomSEF. I've checked that the ZOOfilter plugin is paid, may I ask you if you could send me the package to

for testing? I can assure you that we won't use it for any other purpose.
In the meantime, there are two things you may try:
1. Open JoomSEF -> Manage Extensions -> Zoo -> Common tab and set the "Custom non-SEF variables" option to "search_id" (without the quotes). Then use the JoomSEF's URLs Manager to delete the already created SEF URLs for zoofilter and clear JoomSEF's cache.
2. If previous solution doesn't help, on the same tab set the "Do not SEF URLs matching regular expression" option to "controller=zoofilter" - that way the URLs for ZOOfilter shouldn't be SEFed.
