When something smells unpleasant, our first instinct is often to reach for an air freshener, spray or scented product. A burst of fragrance can make a room smell fresher – but does it actually get rid of the odour?
There's an important difference between masking an odour and neutralising it. Understanding that difference can help you choose the right solution for lingering pet smells, rubbish, musty spaces and other everyday odours around the home.

What does it mean to mask an odour?
Masking an odour essentially means covering an unpleasant smell with another, stronger scent.
Air fresheners, scented candles, diffusers and fragranced sprays can all make a space smell more pleasant by introducing a different fragrance. However, the original odour may still be present underneath.
Think of it like putting perfume on after a workout. You may smell better, but the source of the original smell hasn't necessarily disappeared.
Masking can be useful when you simply want to introduce a pleasant fragrance into a space, but it isn't always the best approach when you're dealing with a persistent or particularly strong odour.
So, what does it mean to neutralise an odour?
Odour neutralisation is about addressing the unpleasant odour rather than simply covering it with another smell.
Odours are caused by airborne compounds that our noses detect. Depending on the product and its formulation, odour-control solutions can work by interacting with these compounds, helping to reduce the unpleasant smell rather than simply replacing it with fragrance.
This makes odour neutralisation particularly useful for smells that tend to linger, such as pet odours, rubbish, food and other everyday household smells.
The goal isn't to make an unpleasant smell compete with a nice one. It's to help create a genuinely fresher-smelling environment.

Why do some odours seem to linger?
Some smells are much harder to deal with than others.
Odours can become trapped in or around porous materials and enclosed spaces, including:
- Carpets and rugs
- Upholstery and sofas
- Pet bedding
- Curtains and fabrics
- Shoes
- Bins and rubbish areas
- Litter trays
- Enclosed rooms and cupboards
- Car interiors
Pet odours can be particularly persistent because they can become associated with both the air and surfaces around where pets spend time.
That's why simply spraying a fragrance into the air may not always provide the result you're looking for.
Masking vs neutralising: what's the difference?
| Masking an odour | Neutralising an odour |
|---|---|
| Covers an unpleasant smell with another scent | Designed to address the unpleasant odour |
| Often relies on fragrance | Can work without simply adding another fragrance |
| The original odour may remain | Helps reduce the perception of the unwanted odour |
| Useful when you want to freshen a space | Useful when you're dealing with persistent unwanted smells |
It's also worth remembering that not every odour-control product works in exactly the same way. Always check the product's instructions and claims to understand what it is designed to do and where it can be used.

Don't just cover the smell
When it comes to unwanted odours, fresh-smelling doesn't always mean odour-free.
While masking an odour can make a space smell better temporarily, neutralising an odour offers a different approach by targeting the unwanted smell itself.
The best solution will depend on the type of odour you're dealing with, where it's coming from and whether you need targeted or ongoing odour control.
So, next time you reach for an air freshener, ask yourself: am I masking the smell, or am I actually dealing with the odour?
