Home Fragrance Oils 10ml
Use Fragrance Oils With Oil Burners And Refill Your Plugin Air Fresheners
These fragrance oils will surprisingly last you longer due to being diluted with another oil, which is made from DPG (Dipropylene Glycol). DPG is generally the most widely used carrier oil to 'cut' fragrance oils, making them even more effective.
If you usually also use plug-in air fresheners, when you get an empty one, simply add some fragrance oil into the bottle (you should be able to twist/pull off the lid and wick) and plug back in. It's a much 'cleaner' kind air freshener, as even plugin's could potentially omit carcegenics, just as the sprays do.
