The Help page: How-to > Guest > Using search filters describes a whole lot of filters, most of which are indeed found in the Filters dialog (reached using the top right Filters button on the home page, for example).
That Help page claims that there are House Rules filters, which would be great (well, essential really) for guests looking for places that have relatively rare features, like Pet Friendly. But that section of filters is absent from the Filters dialog. At least, I don't see it using Firefox on Windows 10.
Am I looking in the wrong place?
