Unwanted smells can be more than just unpleasant – they can affect your wellbeing and pollute your indoor air. Most conventional solutions simply mask the smell with synthetic fragrances, which may do more harm than good. Chemical air fresheners are linked to a range of health concerns for both humans and animals, including hormone disruption, neurotoxicity, and even cancer.
But there’s a much healthier, natural alternative: probiotic odour removers that tackle the root cause of smells, rather than covering them up. Keep reading to find out why probiotic odour control is simple, natural and safe.
Toxin-Free Odour Control is Simple, Natural and Safe
Unwanted smells have many causes – cooking smells, mustiness in your home, stale sweat in your gym, communal office smells, offensive washroom smells – or even your loveable but smelly pet.
And just a hint of questionable odour can subconsciously affect perceptions: Homes feel unclean and workplaces appear unprofessional, even when they aren’t.
But effective odour control is often a challenge and a source of indoor air pollution. This is because air fresheners are often just harmful chemicals or toxins that smell good but pollute your indoor air rather than remove the root cause. Air freshener chemicals are linked to all sorts of health problems for humans and animals, including cancer, neurotoxicity and hormone disruption.
In contrast, probiotics are naturally healthy, live microorganisms (‘good’ bacteria), which eliminate root causes of bio-odours and resolve the problem at the source.
Avoids the Health Risks of Chemical Air-Fresheners
A major cause of unpleasant odours is bacteria linked to organic elements of the decomposition process. These bacteria can grow on surfaces all around you and may smell terrible; they break down organic contamination and release compounds that have an unpleasant smell.
On the other hand, a room that smells fresh can be misleading – and even unsafe. If an air freshener, scented candle or cleaning products with chemical deodorisers cover up the smell you could breathe in a continuous cocktail of chemicals. This pollutes the indoor air, which is known to adversely affect health, and may trigger nasty reactions such as headaches and wheezing.
As chemical air fresheners only mask odours it will soon return – along with any potentially harmful bacteria causing.
How Probiotics Remove Odours Safely and Naturally
This natural approach to odour removal tackles the source of the smell rather than masks it. But how does it work?

In contrast, our Provilan probiotic cleaning products and Odour Remover sprays remove odours in a safe, mechanical and non-polluting way:
- Upon application, a natural, non-toxic ingredient (Polyfix O Sorb) immediately neutralises the bad smell.
- A natural non-chemical aroma, based on organic extracts such as orange and basil, gives an immediate feeling of freshness. No synthetic fragrance needed.
- Probiotics also outcompete odour-causing bacteria for nutrients and space. This inhibits the growth of odour-causing bacteria
- The helpful probiotics also encapsulate and decompose the molecule that is releasing the unpleasant odour. They produce enzymes that break down the whole odour molecule as a natural food source.
- Unlike ‘bad’ bacteria, ‘good’ probiotic bacteria do not create smells: the gases they produce when decomposing organic contamination are non-odorous. This process takes around 5 to 15 minutes to take full effect and eliminate the root cause of the unpleasant odour. Timing depends on the type of surface and room temperature.
- The helpful bacteria create a natural competition with harmful bacteria. They compete for space and other food sources such as organic material, prebiotics, proteins and minerals. This natural competition is well-studied; it reduces the numbers of harmful bacteria and prevents them – and the accompanying odour – from returning.
- The probiotics continue to work for up to three days after application. This helps to keep your indoor spaces fresher for longer.
Also, probiotic products contribute to the circular economy: They continue working in wastewater, safely cleaning inside the drains, pipes and water treatment plants.
