Product Reviews

Hours of research from real customer reviews and expert advice have gone into our product reviews. With our expertise and experience, we bring to you the best plug-in air freshener recommendations!

1. Febreze Plug Odor-Eliminating Air Freshener

Best Overall Plug-In Air Freshener

Our number one recommendation for a plug-in air freshener is the Febreze Plug Odor-Eliminating air freshener. Febreze carefully formulates their products. They’re created without phthalates, formaldehyde or flammable propellants.

This product doesn’t just mask odors. It eliminates them with its OdorClear Technology. Febreze uses cyclodextrin to trap odors and lock them away. It also uses fragrance oils to leave behind a light fresh scent.

Regardless, however, this is a great product for any room. It will keep the air fresh for up to 50 days on the lowest setting. Plus, it’s safe for homes with pets and children!

With this product, you can choose between low, medium, or high settings. The low setting is great for small spaces like bathrooms. For open living spaces, the high setting will work well.

So whether you’re covering up pet odor, or dirty laundry, or smoke — the Febreze plug-in is our top choice.

Please Note

This product is made with synthetic fragrances, not essential oils.

2. Everlasting Comfort Diffuser for Essential Oils

Best Plug-In Air Freshener for Office

When you need to spend long hours in the office, it’s important to stay focused. Many essential oils can help with that, which is why we recommend the Everlasting Comfort Diffuser as the best plug-in air freshener for offices.

If you choose this amazing diffuser, we recommend lemon, black pepper, spearmint or rosemary to help with concentrating on your work (1). This diffuser does not come with oils, but it’s a great product for filling the air around you.

The 400ml tank allows for up to 13 hours of aromatherapy. That’s about two full workdays on one refill!

It has four timer options so if you only want it on for an hour, that’s fine. But you can set it for three hours, six hours of continuous use. It has a lovely cool mist output. When mixed with essential oils, it’ll feel like you’re at your favorite spa — not your office desk.

Of course, if you have pets around, make sure to use pet-friendly oils.

3. Glade PlugIns Air Freshener Warmer

Best Scented Plug-In Air Freshener

We know that scent is important. That’s why the Glade PlugIns is a good pick. It comes in a huge range of scent options. The product also comes with two oils — but there are many more to choose from.

The refills come in eight options. These include cashmere woods, clean linen, vanilla passion fruit, and more. So no matter what your scent preference is, we’re sure you’ll find something you like with this product. Plus, they’re infused with essential oils.

Of course, that means that not every option will be safe for pets! So do your research first depending on whether you have a cat, dog, or bunny.

With the Glade PlugIn, you get a long-lasting fragrance in any room, even ones with high traffic. You can then adjust the fragrance depending on your needs and preference.

Your warmer will also need cleaning from time to time, so keep that in mind. Remove from the outlet and wipe with a dry cloth.

4. Febreze Lavender Plug Odor-Eliminating Air Freshener

Best Odor-Eliminating Plug-In Air Freshener

When you plug-in your air freshener, you want it to eliminate odors — not just mask them. There’s nothing more discouraging than turning your air freshener off, only for the bad smells to return. That’s why we love the Febreze Mediterranean lavender odor-eliminating air freshener.

It cleans away odors properly. Then it leaves behind a relaxing lavender scent, formulated with fragrance oils. However, it’s worth noting that these do not use essential oils.

Regardless, this is great for all odors: pets, kitchen, mudroom, and bathroom odors. Give your nose a break with this air freshener!

Also, good news. It’s compatible with all Febreze plug warmers! Just plug it into the wall, leave it on and let it do the work. It’ll alternate between dual chambers, giving you a consistent amount of freshness.

It also comes in other scent options, but we recommend lavender. It’ll feel like a relaxing overseas escape, without the hassle of traveling.


  • Cleans odors away.
  • Compatible with all Febreze plug warmers.
  • More scent options.
  • Last up to 50 days.


  • Made with fragrance oils.
  • Runs out quickly on the higher settings.

5. Renuzit Snuggle Scented Oil Air Freshener

Best Plug-In Air Freshener for Bedroom

The Renuzit Snuggle scented oil air freshener is our top pick for tackling bedroom odor. It has a cozy snuggly scent which is perfect for relaxing and sleeping.

It smells like fresh, clean laundry with top notes of white florals. With five fragrance settings, you can choose how strong the scent is. It’s also made with essential oils so you get health benefits and avoid harsh chemicals.

Just be careful around pets — do your research first!

What’s cool about this is that it’s a universal warmer. So you can use Air Wicks and Glade warmers with the Renuzit refills. But no need, because this purchase comes with a warmer.

If you’re not a fan of the linen escape scent, there are three other options. This includes lavender, tropical and a super fresh original scent.

6. Air Wick Plug-In Scented Oil Starter Kit

Best Long-Lasting Plug-In Air Freshener

Set and forget — that’s the best thing about plug-in air fresheners! But it’s even better when they last longer, so you don’t have to change them up often. Our pick for a long-lasting option is the Air Wick plug-in scented oil starter kit.

These air fresheners last for up to 45 days per refill, meaning this kit gives you up to 270 days! This is on the low setting. But for nearly a whole year, you’ll have a fresh and scented home before needing to buy new refills.

Plus, the lavender with gentle chamomile and precious woods smells amazing! It’s created with essential oils which is better for your health than fragrance oils. Just be careful if you have pets!

Keep this product in any room of the house. Depending on the size of the room, you can adjust the fragrance settings in five different ways.

Finally, this starter kit from Air Wick has 50 percent less plastic than their other packs. The box is also recyclable.

7. Enerzen Commercial Ozone Generator

Best Plug-In Air Freshener for Commercial Use

If you work in a hotel, run a small business, or are looking for something to bring to work, try the Enerzen Commercial Ozone Generator.

This air freshener also works as an air purifier. Ultimately, it eliminates most bad odors. Whether odors from cigarettes, pets, paint, dust, water damage or cooking — this product can eliminate them. It then leaves you with fresh air so you can breathe happily again.

The reason for this is because ozone generators remove odors by producing large and concentrated amounts of O3 (ozone), according to the Enerzen manufacturer. This breaks down odor compounds in the air. Once the device has been turned off, the O3 quickly converts back into O2 so it’s totally safe. But it’s important that it’s done in an unoccupied room.

Thankfully, there is a timer of 180 minutes so you can set it for how long you’ll be out of a room.

Take Note

this product needs to be used in unoccupied spaces. It’s great for freshening air in hotel rooms once guests are gone, or chef kitchens after hours.

8. Hamilton Beach TrueAir

Best Plug-In Air Freshener for Smoke

To really eliminate smoke smells, you need something a bit stronger than just essential oils. The Hamilton Beach TrueAir can help remove smoke odors. It traps and eliminates the odors — so even after you turn this off, the stench will be gone.

The replaceable carbon filter quietly and subtly filters out unwanted air in your home. So you can go back to having fresh clean air in no time.

When it’s time to change the filter — typically every three months — the device will tell you. The replacement indicator will light up.

This air freshener mounts onto the wall via 110-volt outlets. It is perfect for kitchens, dining rooms, family rooms, and hallways because it eliminates pet, bathroom, and trash odors. You can keep it in other rooms, of course.

Keep your home fresh and the air clean with a Hamilton Beach TrueAir freshener.

Best Plug-In Air Freshener for Car

Don’t worry, we’ve not forgotten about your car! Vehicles can be smelly places, with all the fumes from traffic or picking up your kids after soccer practice. Or the dog smell after their walks. That’s where the Glade air freshener comes in handy!

This air freshener has four adjustable fragrance settings, just place the Glade fragrance into the warmer, choose your desired scent setting and plug it into your car jack. A bright light will tell you that the unit is functioning that’s dims overtime indicating the need for replacement which would usually be after 60 days of usage.

10. Foromans Plug-In Fragrance Oil Wax Melt

Best Plug-In Air Freshener for Bathroom

Let’s face it — the bathroom can be one of the stinkiest rooms in the house. It’s a good idea to freshen it up with a plug-in air freshener. The Foromans Plug-In Wax Melt unit is our top choice for bathrooms.

This unit takes a wax melt, which can be purchased on Amazon or a local candle store! Just pop it into the device and see it quickly melt. The lovely aroma will spread through your bathroom, covering up any bad smells.

It also functions as a night light, so if you have midnight trips to the bathroom, you don’t have to strain your eyes in the light. Plus, it’s very aesthetic and good decoration.

This is a flame-free alternative to candles. While it does use 20 watts of energy, and therefore more than your average air freshener, it’s safe to use around kids.

How to Choose (Buying Guide)

No two plugin air fresheners are the same — so there are important details to consider. This will help you choose the best and safest one for you and your family.

Pet Safety

The most important thing to think about is whether you have pets. Many air fresheners are used with essential oils, which can be toxic to pets (2). Even if you’re not rubbing it onto your pet’s skin, essential oils in the air can still be dangerous.

The list of toxic oils for cats and dogs is different.

Some oils toxic to cats include citrus, pine, peppermint, cinnamon, clove, tea tree, and lavender (3).

Oils toxic to dogs include wintergreen, citrus, ylang-ylang, pine, pennyroyal, sweet birch, tea tree (melaleuca), cinnamon, and peppermint (4).


There are more essential oils that are toxic to pets. Always do your research on an oil before using it in a home you share with your pet!


It’s important to think about the scent in general. Is it something you’ll enjoy? Will it be refreshing in the house? Is it made with essential oils?

We always recommend essential oils over synthetic oils. They’re natural and have many health benefits such as stress relief or support for your immune system.

Length of Freshener

It’s best if the plug-in air freshener will last a long time. If it only lasts a few days, it’ll get annoying to change it constantly. We recommend looking for one that lasts up to 30 days so you can get a good month out of your freshener!


If a plug-in air freshener is refillable, that’s a good choice! You can learn to refill it yourself, or buy refills. This saves you money and waste.

Control Settings

Lastly, look at the control settings. We recommend using higher settings for bigger rooms, so the scent can distribute evenly. But if you want the air freshener to last longer, keep it on the lowest setting.


Do Plug-In Air Fresheners Use a Lot of Electricity?

They don’t use a lot of energy compared to bigger appliances. Plus, they are reusable, so you aren’t wasting cans of aerosol. But also, many use sensors which saves energy when you’re away or in a different room (5).

On the other hand, if you’re looking to save energy, cutting out plug-in air fresheners is fair. A popular plug-in air freshener made by Glade uses 2.1 watts of energy.

If every consumer used theirs for 24 hours a day, 365 days a year, then that equates to 438,000,000 kilowatt-hours. This is equal to half a million tonnes of carbon dioxide — which causes global warming.

So either light an essential oil candle or for peace of mind, don’t keep yours on 24/7!

Are Plug-In Air Fresheners Safe to Leave On?

If you buy from a reputable company, and not a knock-off, then yes, they are safe to leave on.

However, if you have asthma or allergies, plug-in air fresheners might not be safe for you because many are made using chemicals. Most include a chemical called naphthalene which can be hazardous to health (6).

Don’t leave just yet though! We have a few eco recommendations that aren’t made with chemicals.

Are Air Wick And Glade Plugins Interchangeable?

Nope! These two products are designed uniquely and their parts don’t fit together. Some customers jam the refill bit into the opposing brand’s body — but it doesn’t fit perfectly. So this could cause spills.

Are Scented Plug-Ins a Fire Hazard?

Most electrical products pose a fire hazard. While plug-in air fresheners are generally safe to use, even some manufacturers, like Air Wick, state on their website that there is a fire hazard with their products.

Always read the manufacturer’s instructions when starting out with a plug-in air freshener. Also, make sure to not plug-in anything above an air freshener.

Why Can’t I Smell My Plug-in?

The reason why you can’t smell your plug-in is because it may be reacting with oil residue from your old plug-in air freshener. Cleaning the oil warmer removes ghost residues and allows the new fragrance to freshen the air.

Can Plug-In Air Fresheners Cause Sinus Problems?

Plug-in air fresheners can cause sinus problems because they contain chemicals that can irritate nasal passages and your respiratory tract.

Live in Fresh Air

With the best plug-in air fresheners, you can get clean fresh air without doing hard work. Just plug them into the appropriate outlet and then forget about them. Be sure to follow any safety advice from the manufacturer.

Lastly, always think about your pet’s safety if you have animals. Besides that, it’s important to consider the scent, length of use, control settings, and whether the item is refillable. When in doubt, our best overall pick is the Febreze Plug Odor-Eliminating Air Freshener which is safe for pets and lasts up to 50 days!
