DIY: Scented Air Filters

Keeping the home clean and freshly scented is often more work than keeping it tidy. There are many products available to help give your home a fresh scent all day long, but they can often be expensive in that they constantly need to be replaced. Other room fresheners may contain ingredients that may trigger reactions in people with allergies or those prone to chemical sensitivities.

There are a couple of different ways in which you can turn your air conditioning system into a fragrant diffuser by using some common household ingredients:

Lemon Spray

You are able to create a lemon air freshener using a spray bottle, water and a couple of drops of lemon essential oils. Fill the spray bottle with water and add a few drops of the oil into the water and shake to mix. Spray the solution onto your air vents throughout the home. Whenever your air conditioning turns on, the lemony scent will float through the house. Reapply the spray every few days to keep the scent strong.


Every month when you change your air filter, you can add a couple of drops of essential oils to the fabric of the filter. When the air conditioning turns on and the air passes through the filter, the scent of the oil will also waft into the home. Lavender, sandalwood or eucalyptus are all pleasant options.

Dryer Sheets

Your clothes smell so good right after you take them out of the laundry because of dryer sheets. If you want that fresh scent spread around your home, it is easy to accomplish. Grab a few new dryer sheets from the box and stuff them into the ducts behind the room registers. When the air blows through the vent, the subtle scent will carry through the rooms of the home.

All of these ingredients are common, and easy to obtain. By using these instead of a store-bought air freshener, you are able to save money and time!
