Ubbi diaper pail refill bags do the job for this specific diaper pail. Works well and has a lot of room to put the diapers into. I wouldn’t say it totally stops the smell but it does a decent job of masking it

The Ubbi Diaper Pail liners are strong, durable and fit my Ubbi Diaper Pail perfectly. I've been using them for adult diapers and they have been more than strong enough and hide odors very well. They are mostly opaque, which is a plus, and are reasonably priced
