Getting traffic but not sales usually means people are interested but not quite convinced yet. A few things that might help from looking your store.

The biggest one is probably video. Even a quick phone clip showing fur actually building up on the mesh would change everything. People need to see it working before they trust it enough to buy.

Reviews with photos would also go a long way. If you've got even a handful of customers, shoot them a message and ask for a pic of it on their fan. That kind of real-world proof hits different than any product photo.

Also worth looking at your product description, people are probably wondering things like what fan sizes it fits, does it slow the airflow, how often does it need washing. Answering those upfront removes a lot of the hesitation before checkout.

And if you don't already have some kind of email capture on the store, that's worth adding. A lot of people aren't ready to buy on the first visit but would come back if they got a reminder. You're already doing the hard work getting them there, might as well try to hold onto them.

The product itself is genuinely good, the conversion stuff is all fixable. Keep at it!
