1. Place Vanilla Extract or Essential Oils On Your Light Bulbs
Turning on the lights is something that many people have to do on a daily basis anyway, so wouldn't be nice if while they're on they also served the dual function of freshening the air? Simply place a few drops of vanilla extract (or your favorite essential oils) on the light bulbs in your house and every time you turn them on, the heat emanating from the bulbs will help dissipate the scent of the liquid. This easily produces a pleasant smell that will fill every corner of your home. Don't worry, this won't hurt your light bulbs.
2. Scent Your Air Purifier
If you happen to have an air purifier in your home that you regularly use, get more out of it by placing a few drops of the essential oil of your choice on its air filter. Do this about once a week. This is an extremely effective way to disseminate a pleasant smell throughout your house. I personally like using a clean musk or lavender scent to create a clean scent into my home. A few drops of essential oils will suffice, as air purifiers are extremely efficient at spreading the smell throughout a house. Adding too much to the filter might even cause the smell to become a tad overwhelming. And again, don't worry, this won't hurt your air purifier.
3. Get Some Indoor Plants
Did you know that there are many different kinds of plants that you can keep indoors that will clean the air for you? I will post a more in-depth piece on this at a later date, but for now, just know that there are many easy-to-take-care-of plants that will not only freshen the air in your home, but will actually remove toxins as well. This means not only will the air smell fresher, the plants are also improving your health at the same time. Among the plants you might consider getting are golden pothos, peace lilies, aloe plants and snake plans. All of these are extremely easy to take care of and don't require a lot of light or regular watering
4. Make Some Potpourri
If you like placing flowers around the house, then you also know that flowers will eventually die. But don't throw them out! Hang them up upside down until they're completely dried out, then separate the petals from the stem and place them in a bowl. If you'd like you can add a few other things, such as pine cones, to make it more aesthetically pleasing. Then simply take your favorite essential oils and drip them over your homemade potpourri. This should create a nice little decoration that will give off a pleasant scent, tickling the olfactory sense of whoever happens to be walking by. When it no longer gives off a scent, simply refresh the bowl by adding more essential oils to it.
5. Boil Some Lemons
To be honest, this isn't my favorite way to freshen the air in the house but I feel like I would be remiss if I didn't include it in this list. Simply cut up some lemons, and if you like, add a couple cinnamon sticks or sprigs of rosemary to a pot filled with water. Then put it over the stove until boiling. This will allow the natural smells of the ingredients to permeate the house. However, I've tried this method several times and I never felt like the smell was strong enough to my liking, nor did it create a long-lasting scent. Additionally, it required using perfectly good lemons, cinnamon sticks and rosemary sprigs that I could have used to cook other things. It required using up energy by keeping it burning on the stove. Quite evidently, this isn't my favorite method of freshening up the house, but if it is something that tickles your fancy, by try by all means give it a try.
