Netav, You can make your own air freshner easily. All you need is a small glass bottle with a fine mist nozzle. Distilled water and a few drops of essential oil of your choice. Of course the oils have different properties so you'll have to decide which are the ones you prefer. Be sure to shake bottle well before each use.
A good disinfectant room spray
(this is the one I like in the bathroom)
3 drops Eucalyptus
1 drop peppermint
2 drops pine
1 ounce water
