Say goodbye to home fragrance headaches and beat musty or bad smells without harsh chemicals – these natural, $15 non-toxic plug-in air fresheners smell better and last longer
They even prevent pests


Plug-in air fresheners are a very convenient way to make a home smell more inviting, but they are often packed full of harsh chemicals that can trigger headaches, allergies, and leave a lingering artificial odor.
That's why these 100% natural Scent Fill Plug-in Air Fresheners, available at Amazon, are a game-changer, relying on essential oils instead of synthetic fillers.
The best part? They last longer, too. This is why hundreds of people bought them last month to create a non-toxic home.
100% natural, non-toxic plug-in air fresheners
The Scent Fill plug-ins are available in over 80 natural fragrances, all made without synthetic and potentially harmful ingredients. They are plant-based and responsibly harvested, made in the USA, and are compatible with many existing plug-in air freshener modules, such as the Air Wick oil warmers.
While there are several non-toxic ways to make your home smell nice, plug-ins are among the most convenient.
You don't need to watch a pot boil, as with simmer pots, they last far longer than the best fragrant flowers, and they mitigate the fire risk of the best non-toxic candles (perfect if you have clumsy children or curious pets).
Better yet, they have thousands of five-star reviews on Amazon alone, with many shoppers mentioning that the plug-ins did away with the chronic headaches synthetic plug-ins had triggered for them.
Verified Amazon shopper Red Ink, for example, praised the plug-ins for finally defeating year-long odors to make their home smell nice.

They shared, 'I live in a 1400-square-foot home built in 1912, and I have three cats. A previous owner of our house was a cat hoarder, and even though we have taken down walls to the studs and replaced the flooring, the house still smells bad when it warms up in the summer.
'A few times I tried various sprays and plugins, but they typically gave me headaches. Today, we were away all day with the air conditioner barely running, and the house was warm – a usual time when we smell that unpleasant smell upon returning home.
'Instead, we opened the front door, and the whole house smelled amazing! Soft peppermint lingered in the air. My daughter loved it, and I did too. No more funky odors!'
If that wasn't enough, Amazon shopper Bea has had success using the Scent Fill natural peppermint fragrance from Amazon as natural pest control to help get rid of mice in their home.
'We have a garage apartment, and when no one is in there, we’ve had occasional rodent guests. I researched that the peppermint smell could work as a deterrent. I feel that it has. And when I open the apartment for use, it’s easy to freshen up because of the clean scent.'
With scent families ranging from gourmand to spicy to fruits and even ozonic, there is a scent option to suit every taste.
Shopper N Puroff-Main gave their fragrance selection five stars, sharing, 'My house smells like a high-end hotel, without the cost of something like Drift, which you have to subscribe to. Inexpensive and perfect!'
