This is something I've been thinking about. I can see this filter being useful if you're going to keep this machine out in a public area where slight smells are an issue. However I think you're going to get smell from touching the machine with weedy hands and obviously opening/closing it. Plus it's not like anyone that sees it can't google what it is lol. Realistically I think most of us keep these in our grow rooms and even with central air it won't smell enough without the filter to be an issue IMO. I'm not sure how useful this filter is. My DIY machine doesn't use one and drips into the drip tray and it doesn't generate significant odor. The condensate it drips smells slightly like weed. As far as I can tell it's basically a little drop-in water filter (similar to these), and they can definitely get funky and moldy if not frequently changed or kept routinely wet with fresh clean water. Especially because we're storing dead organic matter that is a source of food. Obviously the machine condenses a ton of water when drying a batch, i.e. mine overflowed. However, once it's done it doesn't drip much anymore. I suspect it's probably better to run it without a filter unless you really are sensitive to the smell, and even then I'd probably just run the filter during the dry/cure stage and take it out for storage.
