The Best Plug-In Air Freshener Refills

No one likes a smelly room. No matter where the smell stems from, if it stinks, you want it gone. Thankfully, there are some great options for odor killers to help you do that, including candles, room spray, and incense. However, if you want something that neutralizes bad odors before they have the chance to take hold in a room, you want a plug-in air freshener. With one of these, you can plug it in and forget about it. No need to turn it on and off each time, stress about leaving a flame burning, or worry about smoke in the house. Plug-in air fresheners keep your home smelling clean and fresh with minimal effort on your part. If you are not sure which air freshener refill is the one for you, read on to learn about the ones that made our top list.

Best Overall

We love a good candle, but typically, candle scents don’t last very long and there’s always the hazard of forgetting to blow them out. With a plug-in freshener, though, you don’t have to worry about either of those things. These Glade refills feature a “cashmere woods” scent that lasts, lingering in the room in which it’s installed. With this 3-pack, there are enough to put in a few different rooms in your home to keep everything smelling great. Between the 3, you’ll have up to 150 days worth of fragrance that you can just plug in and forget about. We love that convenience.

Pros:

  • Each refill lasts up to 50 days
  • Flameless way to fill your home with fragrance
  • “Cashmere woods” scent is not overpowering

Cons:

  • The scent isn’t strong enough

Though technically a pack of 3, these air fresheners have dual cartridges that alternate between two scented oils. This is a great way to ensure that your nose never gets too accustomed to one scent and quits noticing it. It is also a great way to give you more between each refill. One plug-in freshener will give you 1200 hours of fresh smells in your home, which means the whole pack lasts 3600 hours (or 150 days).

Pros:

  • Dual cartridges alternate between two scented oils
  • Great bulk purchase

Cons:

  • Only lasts full 150 days  on a low setting

You’ve likely seen automatic sprayers in public bathrooms, and this one is a similar, smaller model intended for your home. The can of air freshener sits inside of the spraying unit and an internal timer sprays the scent on a regular schedule. This means no work for you aside from putting the batteries on. You don’t need an outlet to make this work, either — you just need to install 2 AA batteries that are included. The sleek, modern design won’t be an eyesore in your home, and it ensures a good range of spray that is wide enough to cover a big area.

Pros:

  • Doesn’t require an outlet to plug into
  • Sleek modern design blends in with most homes’ decor
  • Neutralizes bad odors

  • The scent doesn’t last long

Frequently Asked Questions

Are plug-in air fresheners safe for dogs and cats?

It’s best to avoid putting air fresheners near your pets’ food and water or near your cat’s litter box. Typically, air fresheners are plugged in right at the level of your pet’s nose, which can cause it to affect the animal’s breathing. Try to place the air fresheners in areas where your pet does not frequent, as breathing in too much of the scent at the same level as the freshener can affect your pet’s ability to breathe.

Do plug-in air fresheners use a lot of electricity?

Air fresheners work thanks to a small interior electric heater that warms up the oil refills. The average plug-in freshener uses 4 watts of electricity, which means that if it’s left on all the time, it uses 35 watts per year. That is almost nothing at all, especially when compared to something like an air fryer that uses between 1,400-1,700 watts of electricity per hour.

Are plug-ins a fire hazard?

According to the Consumer Product Safety Commission, the chances that a plug-in sparks a fire are very slim. Most of the time fires of this kind are caused by faulty wiring, not the actual air freshener itself. So you can have a plug-in such as the above in your home without concern of hazard.
