Dried and fresh herbs and spices are great to use.
Make sure you use only budgie safe herbs and spices and you can actually place dishes of them around your apartment.
It won't hurt if the budgies decide to nibble on them and you'll have a nice fragrance instead of stale air.
You can also simmer cinnamon, nutmeg, cloves and/or allspice in a bit of water which will make your home smell amazing.
Another thing you can try is taking an orange, poking holes in it and ****ing whole cloves into the holes.
The fragrance will last a long time as the orange dries out.
There are many things to consider when buying an air-purifier and it's good to do as much research as possible to determine what one will best suit your needs.
