The Air Ninja Trash Can Diaper Pail is our pick for best diaper pail. It’s a great option for those who prefer a traditional-style pail over a bagless design. The Air Ninja Pail keeps odors locked away with its nanotech odor-eliminating carbon lining.
The Air Ninja’s lid isn’t quite as secure as the Roomba’s, but it’s still relatively secure thanks to the locking latch. It also has a pull-down handle that makes opening the lid easier, though it can be a little tricky to pull down at first.
