No one likes nasty niffs in their home. Whether you have pets that pong or don’t want to smell last night’s dinner when you’re eating breakfast, the best plug-in air fresheners are a hassle-free way to make sure your house always smells great.
They’re a safer option than candles and generally release scent around the clock – or when scheduled – so your room will keep smelling good even if last minute visitors turn up unexpectedly. Most are extremely simple to operate and simply need plugging in to begin releasing fragrance. Some use scented gel beads while others use liquid fragrance or essential oils and most can be easily refilled. There’s a wide range of scents to choose from, whether you prefer the airy smell of freshly washed bedding, a burst of fruitiness or even a sophisticated fragrance you might find in a five-star hotel.
If you don’t fancy the traditional version, I’ve also included some other plug in options to suit every need from air purifiers to diffusers that can be plugged into the mains. Here is my pick of the best.

Febreze 3volution air freshener plug
Best: plug-in air freshener overall
Type: Wall plug-in
Scent type: Liquid fragrance
Intensity settings: Yes
Why we love it
- Long lasting
- Lights to show when refill is due
- Lots of fragrances to choose
Take note
- Not the most attractive
This has everything you could need from a plug-in air freshener, with an ingenious twist. It’s super-simple to get up and running and comes with three complementary scents. All are easy to unscrew and all slot in at the same time.
That’s when it gets clever. The air-freshener alternates between all three scents every 45 minutes, so you don’t get ‘nose-blindness’ but keep noticing the fresh scent, which is a fantastic idea. I really noticed the difference using this plug-in and several visitors passed comment on the fact my house smelled good. Best of all, the scents last for up to three months on the lowest setting, even when the plug is turned on for 12 hours a day, which makes this air freshener even better value. A light flashes when you need a refill, which is handy, and when it’s time to buy more scents, there’s a useful scratch-and-sniff panel on the outside to help pick your favourite smell.

Yankee Candle scentplug diffuser organic pattern base
Best: budget plug-in air freshener
Type: Wall plug-in
Scent type: Liquid fragrance
Intensity settings: Three
Why we love it
- Great range of smells
- Looks stylish
- Scratch and sniff panel to test fragrance
Take note
- Scents must be bought separately
It’s no surprise that Yankee Candle knows a thing or two about making homes smell lovely. I was also really impressed by this diffuser’s simple but stylish white textured design to stop the plug looking too obvious.
It can be used with a great range of refills, from the festive ‘cinnamon stick’ to the floral ‘wild orchid’, which slot easily into the bottom of the diffuser. There are three different intensity settings that can be adjusted to suit. I used the summery ‘pink sands’ scent, which is a gorgeous blend of citrus freshness with a spicy vanilla, which I’d be happy using year-round. I especially loved the fact the box came with a scratch-and-sniff panel on the outside, so you can easily try before you buy. The smell lasted well, with no sign of fading after nearly a month’s use, though it’s not extremely powerful. I liked its subtlety but if you prefer a stronger smell or are using in a large area, you might prefer to choose a different scent or try the Febreze 3volution plug-in air freshener.

Magnifiscent zenplug
Best: plug-in air freshener for a five-star hotel feel
Type: Plug-in diffuser
Scent type: Undiluted fragrance oils
Intensity settings: Yes
Why we love it
- Can be adjusted via an app
- Fantastic scents
- No water or heat used
Take note
- Larger than usual plug-ins
If you’ve ever wanted your home to smell like a luxury hotel, look no further than the ZenPlug. Billed as a plug-in diffuser rather than an air-freshener, it uses cold air diffusion technology to deliver pure fragrance on demand without heat or water. That means it’s not messy to fill and the oils last longer. You simply pour an oil of your choice into the pre-supplied bottle and add this to the ZenPlug. Spare bottles can be bought separately if you want to swap between scents. There’s a soft ambient light on the diffuser and, very niftily, the intensity and even schedules can be set via an accompanying app so you can save on oils when you’re not home. It can also be used without the app via the buttons on the front. I found the app worked really well but I had to experiment a little to find the best schedule, frequency and intensity that worked for me.
But that’s not even the best part. I loved the fact the oils are ‘inspired by’ well-known fragrances and even specific hotel chains known for their distinctive smell. I tried several but my favourites included English Pear & Freesia, inspired by the Jo Malone perfume of the same name, and Elegant Retreat, which apes the sort of smell used in the Four Seasons hotels. Others take their cue from fragrances by Tom Ford, Bvlgari and Chanel so you can cheat your way to an expensive-smelling home that will impress any guest.

Bath & Body Works wallflower gift set
Best: plug-in air freshener for a laundry day smell
Type: Wall plug-n
Scent type: Liquid fragrance
Intensity settings: No
Why we love it
- Comes with two scents
- Great fresh scents that last well
Take note
- Intensity can’t be adjusted
- Unexpected opening
Nothing beats the smell of freshly washed bedding, so this plug-in air freshener gets the thumbs-up for its clean, linen-inspired fragrances. It comes with two – the slightly apple-y ‘sun-drenched linen’ and ‘laundry day’, which has hints of eucalyptus and lavender. I loved that I didn’t have to buy anything extra to get started, and each 24ml bottle screwed in easily to the diffuser, which simply needed plugging into a socket and left alone, as the intensity can’t be adjusted. The diffuser itself is plain white plastic for an unfussy feel that is barely noticeable when plugged in.
The only downside is that I spent quite a while trying to open the bottles before realising – be warned - that they unscrew the opposite direction from what would be expected. The intensity also can’t be adjusted, so if you’d rather choose one that can, try the Yankee Candle ScentPlug diffuser organic pattern base instead.

Diptyque electric diffuser
Best: luxury air freshener plug-in
Type: Wall plug-in
Scent type: Gel beads
Intensity settings: No
Why we love it
- Only releases scent when you want it
- Choice of nine Diptyque scents
- Looks great
Take note
- The diffuser and refills are expensive
If you thought plug-in air fresheners couldn’t be stylish, think again. This pricey plug-in diffuser comes from prestigious French fragrance brand Diptyque and looks every bit as good as you’d hope, with the company’s signature typography in a matte gold on the front. I definitely didn’t want to hide it away on a plug out of view like I did with some of the other plug-in air fresheners I tested.
To use it, you need to attach one of the three socket fittings it comes with (making it great for travel) then add a scented insert, which come in nine iconic Diptyque fragrances and last for about 40 hours. A light touch anywhere on the gold vent delivers a burst of fragrance whenever you need it. This can be stopped by pressing again or will stop automatically after three hours. I liked having the smell on demand, so I only used it when needed. The fragrance refill can be changed with another any time if you fancy a different smell, but it must be kept in its sealable pouch when not in use. I opted for the classic ‘baies’ with notes of berries and rose, but at around £40 a time, I’ll need to add refills to my next Christmas list.

Henyall 2-piece plug-in air purifier and automatic air freshener
Best: plug-in air purifier
Type: Wall plug-in
Scent type: None
Intensity settings: No
Why we love it
- Easy operation
- Safe to use for 24 hours
Take note
- No way of telling if it’s working
Not sure about scenting your home but still want to freshen up the air around you? This pack of two plugs acts as a portable air purifier, which it’s claimed releases 20 million negative ions per second to clean the air to help neutralise smells from pets and smoke and reduce allergens from dust and pollen.
It’s a big claim and – in all honesty – there’s no real way of telling if these actually work. They are super-simple to operate, though. Simply plug each one in and turn it on and a light shows it’s working. The set doesn’t come with any real instructions otherwise and doesn’t need any ongoing maintenance, so you won’t need to change filters or add refills. It’s also safe to keep them plugged in all the time and the air did feel a little fresher during use, without resorting to an artificial fragrance. They’re also unobtrusive and for the price, I’d definitely be willing to leave both plugged in for the potential benefits.

Dunelm white ceramic electric diffuser
Best: electric diffuser
Type: Electric diffuser
Scent type: Essential oils
Intensity settings: No
Why we love it
- Looks elegant
- Optional timer settings
- No requirement to buy specific oils
Take note
- Need to buy oils separately
Choosing a plug-in diffuser is a great way to get the same effect as an air freshener but make more of a feature of it in your home. This brilliantly priced option from Dunelm has a lovely textured ceramic finish with a wood-effect base that looks a lot more expensive than it is. Like an air freshener, it plugs directly into the mains, so you won’t need to worry about it running out of charge, although if you’d rather hide your air freshener away, opt for a smaller plug version such as the Glade plug-in air freshener holder and three refills instead.
It's very simple to operate. Add water inside and around six drops of essential oil and press the button on the front to choose one, two or three hours of operation or to have it run continuously. A second button operates the LED light strip at the bottom. This can circle through a series of colour changes or can be fixed on or turned off entirely, which is useful. I generally liked to keep it fixed on a white light, which cast a gentle glow in my living room. You do have to buy your own essential oils to get started with this diffuser, but these are easy and cheap to pick up and it’s great to not be tied into a particular brand each time you need more.

Glade plug in air freshener holder and three refills
Best: long-lasting plug-in air freshener
Type: Wall plug-in
Scent type: Liquid fragrance
Intensity settings: Yes
Why we love it
- Intensity settings work well
- Lasts a long time
Take note
- Highest setting is quite strong so should only be used in a large room
This plug-in air freshener couldn’t be easier to use. Unscrew the fragrance bottle, slot it into the bottom of the holder and plug in. The top of the holder twists to adjust intensity, which works very well (although, I found the highest setting a little too full-on for me).
There are all kinds of fragrances to choose from and it’s easy to buy refills without forking out for the holder again. My favourite was ‘pure clean linen’, which smells like fresh bedding hanging on a washing line but all scents are infused with essential oils so they smell stronger than some other air-fresheners. Most impressively, each refill can last up to 120 days, and this pack comes with three refills, so you won’t need to think about buying any more for months.

What is the best plug-in air freshener?
The Febreze 3volution air freshener is the best plug-in choice to scent your home. It’s affordable and I loved that it alternates between three different scents to keep things fresh. Though not strictly an air freshener, I also really rate the Magnifiscent ZenPlug, which has an impressive range of luxurious smells and an easy to operate app which means you can control when and how your house is scented. If you’d rather spend less, I also loved the Yankee Candle ScentPlug diffuser organic pattern base, which looks attractive, isn’t too overpowering and has a great choice of smells available so you can change it up to suit your mood or the season.
