Best For Cold Rooms: Air Wick Plug in Scented Starter Kit
- Eco-friendly – including a cardboard box
- Ideal for cold rooms – very strong yet comfortable scent
- The bottle design is prone to leak
If you love tropical fruit fragrance, then we highly recommend this scented kit from Air Wick. It’s a unique combination of pink papaya and vanilla for a sweet and relaxing feel.
Like other siblings, this scent is comfortable but very strong, which more suits cold rooms.
We love the included cardboard box for less plastic waste and more protection to the environment. It also holds all the vulnerable glass bottles very well.

Scents in cold rooms are less active than in hot rooms, therefore, you should pick a bold air freshener like the Air Wick Plug in Scented Starter Kit
Best For Kitchen: Febreze 00037000259947
- Good for kitchen - Able to eliminate odors
- Bold yet not overpowering - Fade Defy Technology
Citrus fruits are a great choice to cover oil odors in the kitchen. But if you’re bored of common scents like pure lemon or orange, then we think this option will interest you. It’s a mix of passion fruits, pineapple, and atemoya.
Adopting Fade Defy Technology, the air freshener fragrances quickly and lingers for very long.
But the best part is it can eliminate oil odors in your kitchen before leaving behind a refreshing scent. The only thing we don’t like about it is the price – so pricey!

How To Choose The Longest Lasting Plug In Air Freshener?
Length Of Freshener
Talking about the scent time of plug-in air fresheners, there are a lot of options in the market commonly ranging from 7 up to 90 days. The longer the scent time, the more expensive the product.
The choice is up to you, especially your budget and needs.
For long-term uses, our expert testers advise choosing a plug-in air freshener that lasts at least 30 days so you don’t need to change it constantly. If you’re a seriously budget-conscious shopper and do not use an air freshener quite often, it is fine to opt for a shorter one.
A plug-in air freshener isn't required to function constantly in some cases - like in the bathroom or laundry room. To optimize the scent time, you can turn the device on and off according to your needs.
Or, a more effortless solution is to choose a plug-in air freshener with multiple time settings or delay function.
Multiple timer options allow you to have the device worked in a certain period of time depending on the chosen setting, then automatically shut off.
The delay function is a bit different: It functions for a certain period of time, then pauses (also for a certain period of time), then restarts, and keeps repeating this cycle until the scent is out or you shut it off.
Another recommended function is scent intensity adjustments. The higher settings release bolder fragrance – which is suitable for large rooms; the lower settings are on the opposite.
This function is versatile and comes in handy for a house with rooms of different sizes.
While plug-in air fresheners that scent from essential oils are health-friendly to humans, some of them aren’t to cats and dogs.
Oils like peppermint, cinnamon, tea tree, sweet birch, pennyroyal, pine, ylang-ylang, citrus, and wintergreen are toxic to dogs. Meanwhile, oils like lavender, tea tree, cinnamon, citrus, clove, and peppermint are toxic to cats.
Therefore, if you are a pet parent, consider choosing the right oil that suits your scent preference and your pets.

How do air fresheners work?
The way air fresheners work is to diffuse fragrance into the air – either as particles of fragrance ingredients that evaporate directly from a source or as droplets transitioning to vapor - to cover unpleasant odors and leave behind a good smell.
Can plug in air fresheners cause fire?
The case that an air freshener sparks a fire rarely happens. The cause of most such fires were reported from faulty wiring in the house.
Can you leave plug-in air fresheners on all the time?
No, you can’t. Although a plug-in air freshener rarely causes a fire hazard, leaving it on all the time is wasteful of scent and energy.
Do plug-in air fresheners use a lot of electricity?
No, they don’t. A typical plug-in air freshener consumes around 4W, which is very little.
Can you plug an air freshener into an extension cord?
No, you can’t. It is not recommended plugging an air freshener into an extension cord for safety.
