Odour removal is essential for maintaining a healthy and comfortable living or working environment. Bad smells can contribute to stress, health issues and a general sense of uncleanliness in a home.
This article will guide you to the various causes of odours, effective methods for removal, preventive measures and guidance on when to enlist professional help. Whether you’re a homeowner seeking to freshen up your space or a business owner trying to make a good impression, this guide will provide you with valuable insights.
What Is Odour Removal?
Odour removal is the process of eliminating unpleasant smells from an environment. This goes beyond simply masking the odour with air fresheners. It involves neutralising or completely removing the source of the smell to ensure it doesn’t return.
Understanding Odour and How It Forms
Odours develop from various sources, both biological and chemical. Biological sources include mould, food spoilage and pet waste, while chemical sources range from paint and plastics to industrial fumes. These sources release molecules into the air that stimulate our olfactory system.
Here are some common odour sources:
- Fungus – Moulds and mildew emit volatile organic compounds and often cause a house to smell musty. This is also caused by poor ventilation, excess moisture or water intrusion in the room.
- Food – As it spoils, food stinks due to the presence of bacteria, mould and yeast. Cooking compounds from strong-smelling foods like fish and garlic also enter the air and cause odours.
- Human waste – Plumbing issues can cause waste or gases to back up, causing foul odours. Issues with plumbing systems, such as sewage backups, leaky pipes or blocked drains, can release unpleasant odours.
- Pets – Dirt and sweat that linger on dogs can lead to unpleasant odours, and waste in cat litter can make your home smell unpleasant. Pet dander, urine, or litter boxes can bring distinct smells into a home, particularly if not regularly cleaned or maintained.
- Chemicals – Newly painted surfaces, freshly installed carpets, or using certain cleaning supplies or household products, such as adhesives or solvents, can release strong chemical odours in an enclosed space. The source of odour molecules can be natural, originating from organic materials (moulds, stagnant water) or chemicals (hydrocarbons, essences, gases, synthetics).
Masking vs Eliminating Odours: What’s the Difference?
Masking odours involves covering up unpleasant smells with stronger, more pleasant scents (fragrances). While this provides temporary relief, it doesn’t address the underlying cause.
Eliminating odours, on the other hand, means neutralising the source or absorbing the smells entirely. Neutralisation alters the chemical structure of the odour molecules. Absorption involves binding the odour molecules to a substance, such as activated carbon, effectively removing them from the air.
Common Causes of Odours in Homes and Businesses
Odours can originate from numerous sources, and understanding them is the first step toward effective removal.
Household Odour Sources
Common household odours can arise from:
- Cooking smells – The smell of garlic, fish, spices and oil can linger long after they’re cooked.
- Pet odours – Urine, wet dog smells and other pet-related scents
- Mould and mildew – These are often found in damp areas such as bathrooms and laundry rooms.
- Smoke – Smoke from cigarettes or fireplaces permeates fabrics and surfaces.
- Rubbish buildup – Accumulation of food waste and other types of rubbish in kitchens or bathrooms can lead to foul smells.
Commercial & Industrial Odour Sources
In commercial settings, odour issues may arise from:
- Office air quality – Stale air, dirt and lack of ventilation can lead to unpleasant carpet odours.
- Restaurants and kitchens – Grease buildup and food waste create strong odours.
- Hotels and other hospitality establishments – Residual cigarette smells, body odour and uncleaned rooms can deter guests
- Factories and warehouses – Chemical fumes from machinery and processes, including voltalite organic compounds, can introduce harmful odours

What are the Best Methods for Odour Removal?
Natural Odour Removal Solutions
Natural remedies are often effective for light odours. Consider the following options:
| Solution | Best For | How to Use |
|---|---|---|
| Baking Soda | Pet odours, fridge, carpets | Sprinkle, leave overnight, then vacuum |
| Vinegar | Bathroom, smoke, mould | Spray on a microfibre cloth or old newspaper and wipe the surface |
| Activated Charcoal | Lingering musty smells | Put inside a pouch and place in rooms or closets for continuous absorption |
| Essential Oils | Freshening up a room, minor odours | Diffuse or mix with water for sprays |
| Citrus-Based Cleaners | Mild kitchen odours | Place orange or lemon peels in waste bins or rub on surfaces |
These methods work well for light and everyday odours. For deep cleaning needs like mould, smoke damage or pet stains, especially in carpets, sofas and mattresses, professional treatment is recommended.
Chemical-Based Odour Neutralisers
Chemical-based products can provide stronger odour removal. Common options include:
- Enzyme cleaners – Effective for pet urine and other organic stains. Apply directly to the stain and follow product instructions.
- Hydrogen peroxide and alcohol-based solutions – These can be effective for some odours but should be used cautiously as they can bleach or damage certain materials.
Safety is paramount with these products. Make sure to follow guidelines and regulations regarding use, especially in industrial settings.
Air Purification and Ventilation Strategies
Effective air purification is vital for odour management. Consider using:
- HEPA filters – They trap airborne particles, including odour-causing molecules.
- HVAC cleaning – Regular cleaning ensures your HVAC system isn’t circulating dust and allergens that contribute to odours.
- Fresh airflow – Open windows and doors to ventilate the space regularly.
- UV light systems – Improve indoor air quality by reducing bacteria and odours.
- Air-purifying plants – Certain plants can help filter the air and reduce odours. Examples include snake plants, spider plants and peace lilies.
Professional and Industrial Solutions
When odours persist or are particularly strong, consider professional methods such as:
- Dry fogging – This method uses a machine that disperses dry fog to neutralise odour molecules.
- Thermal fogging – It uses heat to create a fog that penetrates deep into surfaces to deodorise a room.
- Hydroxyl generators – These machines produce hydroxyl radicals that break down odour-causing VOCs and germs.
- Industrial HVAC odour filtration systems – These are designed for large spaces with complex ventilation systems.
These solutions typically require specialised training and equipment, so hiring professionals is crucial for effective results.
Health and Environmental Impacts of Odours
Odours can significantly impact both our physical and mental well-being. Strong or persistent odours can trigger allergies, respiratory issues, headaches and even nausea. Certain chemical odours can also irritate the eyes, nose and throat.
Beyond the immediate physical effects, odours also play a crucial role in our psychological state. Unpleasant smells can contribute to stress, mood disruptions and even sleep problems. Imagine trying to relax or sleep in a room with a lingering, unpleasant odour – it can be incredibly difficult.
How to Prevent Odours from Returning
Consistent maintenance can prevent odours from reappearing. Adhere to these best practices to prevent them from returning:
- Regular cleaning – Deep clean carpets, upholstery and kitchens.
- Proper waste disposal – Adhere to waste management and recycling protocols.
- HVAC regular maintenance – Change filters regularly, ensuring clean airflow.
- Moisture control – Use dehumidifiers and fix leaks to prevent mould and mildew growth.
- Air circulation and filtration – Keep windows open when possible and use high-quality air purifiers for better indoor air quality.
- For offices and workspaces – Ensure proper ventilation and regular cleaning schedules.
When to Hire a Professional for Odour Removal?
