Take a sniff of the air around you.

The delicious smell of freshly baked bread…the repulsive odour of rotting fish…the chemical smell of disinfectant…the lingering smell of tobacco…the charming fragrance of jasmine flowers. 

We live in a world of smells, each smell being distinct in its own way. While we cannot detect all smells, we know that some smells attract us, some make us turn away, and some release harmful gaseous pollutants.

Smell is not visible and doesn’t pose immediate symptoms, many often overlook the impact of it and are unaware that some unpleasant odour could harm our health in the long run.

Air purifiers could be the ideal solution to solve the above situations, but do you know which component plays the key role in neutralizing the unpleasant odour or harmful chemical gas pollutants? Activated carbon is the game changer.

Common Sources & Types of Indoor Air Pollutants

We have all equipped ourselves with knowledge of the risk of outdoor air pollution – haze, open burning, and fumes from cars and factories. Yet, we have neglected that we spend most of our days cooped up inside offices, factories, gym centres, and restaurants, which have more than one source of indoor air pollutants that can harm our health from the cumulative effects.

Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems. Inadequate ventilation can increase indoor pollutant levels, whereas high temperature and humidity levels can also increase concentrations of some pollutants. Gaseous pollutants and odours can be trapped indoors for a long period of time.

Understanding harmful and unpleasant indoor air pollutants is important to eliminate them. Read more below to take the first step in improving indoor air quality by identifying the common sources and types of indoor pollutants.

Volatile Organic Compounds (VOCs) from Household Products

Volatile Organic Compounds (VOCs) are gases from products or processes that are released into the air. Some are harmful by themselves, and some react with other gases to form other air pollutants. They can cause damage to your central nervous system, liver, and even cancer. 

Many commonly used products that we use at home or in commercial spaces release VOCs, such as:

• Paints, strippers, and finishes.
• Personal care products.
• Aerosol sprays.
• Cleaners.
• Deodorisers.
• New furniture (like cabinets, beds, carpets, and wood floors.)

Dust and Allergens

Dust mites and other allergens, like pets, are considered a type of air pollutant. Their ultrafine particles are unnoticeable to the naked eye and can be absorbed into the bloodstream. While they may seem harmless, dust and other allergens can cause discomfort and signal bad air quality.

They reduce indoor air quality as it settles and resettles throughout your space. Without proper ventilation or air filtration solutions, the constant circulation of fine dust and allergen particles can cause severe health issues, especially those with allergies, asthma, or other respiratory problems.

Mould and Mildew

Mould is a fungus that signals a humidity issue in an indoor environment. It can often be found in damp and dark areas with a musty smell. It breaks down materials and develops and spreads new spores. If not taken care of, it can spread to humans and pets and affect the indoor air quality.

Mould is an air pollutant, so tackling it is crucial to improve indoor air quality and quality of life. While it may not seem dangerous, inhaling mould spores can lead to health problems. To avoid mould growing and affecting the air quality indoors, ensure the moisture levels in your home are not excessive.

Tobacco Smoke

Tobacco smoke is well known for being a major indoor air pollutant. Also known as aerosol, tobacco smoke is a mixture of 90% gas and 10% harmful particulate matter, which is why it is one of the most significant contributors to bad indoor air quality. 

Tobacco smoke is a harmful air pollutant because of its high-temperature combustion. It contains particles from the additives and paper, such as tar, nicotine, heavy metals, soot, and more. When released into the air, it adversely affects the air and odour quality. Check out products here.

Formaldehyde

Formaldehyde is a common indoor air pollutant, as it is found in many household products. It is a form of VOC that releases a pungent odour and can cause eye, nose, throat, and lung irritation, even at low concentrations.

Some sources of formaldehyde indoors are common in personal care products like shampoos, hair care products, soaps, nail polish, and body washes. Without proper ventilation or filtration, formaldehyde can circulate and react with other air pollutants, creating an environmental risk.

Animal dander

While pets are a source of happiness for many, animal dander is often an overlooked air pollutant. Like allergens, animal dander is one of the top sources of indoor air pollution. Often, animal dander reacts to other air pollutants like tobacco smoke and dust mites, making it more toxic than most outdoor air quality.

Animal dander includes tiny pieces of shed skin, feathers, and fur that are pervasive towards indoor air quality. It can even invade spaces with no pets or animals, like libraries, workplaces, and hospitals, as they are undetectable. They can end up in the respiratory tract, which can cause allergic reactions and respiratory problems.

How To Measure Bad Odour

Bad odours may seem harmless, but excessive concentration of it in the air and cumulative exposure can be harmful. We could experience sensory issues, like irritation of the eyes and nose, especially in enclosed environments with high concentrations of bad odours, such as industrial plants, disposal facilities, and oil and gas extraction facilities. 

Because of its environmental and health risks, certain countries and regions have established rules and regulations regarding odour control. This is to measure the impact and severity of emitted chemical compounds in odour emissions on the health and environment.

Here are the ways professionals measure the severity of bad odour:

• Dynamic olfactometry
• Chemical analysis (with speciation or non-specific)
• Gas chromatography-olfactometry (GC-O)
• Tracer analysis
• Instrumental odour monitoring by e-noses
• Field inspection
• Field olfactometry

Safety Level & Guide To Bad Odour

Odours or smells contain chemicals that, at higher concentrations, may harm us. For example, you might experience headaches and nausea from the smell, which can lead to more harmful effects depending on a person’s sensitivity to smells. The effects can also worsen if you are exposed to the smells for an extended period.

With rules and regulations in place to control and measure bad odour, there is less of a safety risk. Here is a guide to bad odour, including how to handle it and when it might cause a health hazard.

How to Handle Bad Odour

• Find the source of the bad odour to eliminate or contain it.
• Check for either mould, garbage storage, pest infestation, filtering system, gas leaks, or faulty wiring.
• Ventilate indoor space by opening windows and doors and turning on fans.
• Employ professionals to measure the severity of bad odours towards people and the environment.

When is Bad Odour a Health Hazard

Bad odours can be health hazards when someone experiences sensitivity towards them. Some of the symptoms might look like:

• Eyes, nose, lungs, and throat irritation
• Nausea
• Headaches

• Shortness of breath
• Nasal congestion

Essential oils come in various scents that can fit your needs. Some, like lemon essential oil, help neutralise and eliminate bad odours.

• Challenges

They are only a short-term solution as most only mask bad odours. Furthermore, the oils release a range of VOCs when diffused into the air, which worsens indoor air quality and might trigger those with allergies and respiratory problems.

Hydrogen Peroxide

• How It Helps Remove Odour

Hydrogen peroxide comes in various potencies, from 3% to 32%, to help you tackle odour issues in any enclosed space. It can be used on various surfaces, like appliances, kitchens, toilets, tiles, and laminates.

• Challenges

While it can be used on various surfaces, it might damage them if used excessively. It is not suitable for carpets, curtains, or other fabrics because it may cause discolouration.

Vinegar

• How It Helps Remove Odour

While vinegar might not seem like the most pleasant solution to work with, it is a great way to eliminate odour without releasing harmful chemicals.

• Challenges

When using or handling vinegar to help with bad odours, you need to wear gloves. Vinegar is acidic, and prolonged exposure can irritate the skin. The sour and pungent smell of vinegar will linger in the room for a long period of time, and it could damage some surfaces like granite and marble.

Odour Absorbing Materials

• How It Helps Remove Odour

Odour-absorbing materials are a great way to eliminate odours as they absorb and contain them, which makes them highly sustainable. Materials like charcoal, wood, bamboo, and activated charcoal are amazing materials to remove bad odours.

• Challenges

It isn’t a practical solution for a large-scale odour problem, as it would require placing odour-absorbing materials in every corner of a space.

Proper Ventilation

• How It Helps Remove Odour

Proper ventilation helps in reducing the intensity of bad odours. By opening doors and windows and turning on fans, it ensures the air indoors doesn’t remain stagnant and helps remove indoor air pollutants. For spaces that may accumulate more odours, like kitchens and toilets, proper ventilation is crucial.

• Challenges

While this is a good solution, it might not work for every environment. Some environments have bad outdoor air pollution that draws bad air indoors, and some spaces do not even have a window.

How Air Purifiers with Activated Carbon Filters Improve Air Quality

When you open up your air purifier, you’ll see a filtration layer in black, which is carbon. Carbon air filters trap gas molecules on a bed of charcoal, often used to remove odours and gaseous pollutants from the air.

Activated carbon is carbon that has undergone some additional processing to make it better at trapping gas molecules. These special properties allow it to remove volatile organic compounds (VOCs), formaldehyde, tobacco smoke, odours, and other gaseous pollutants from the air, and even some strong and harmful industrial chemical gases which can’t be seen and are odourless.

Air purifiers with activated carbon filters do have these additional benefits:

• Air purifiers with carbon filters do not release scents, reducing the risk of triggering scent-related allergies.

• They’re long-lasting and cost-effective solutions that are reliable for years to come.
• Filters out harmful gaseous pollutants and VOCs and helps eliminate odours through adsorption.
• Improves overall quality of life through a better working or sleeping environment.

How To Select Suitable Air Purifier with Odour Removal in Malaysia

Activated carbon filters are often used in parallel with a HEPA Filter. Together, this combination creates a top-quality, industry-leading air purification system that will remove a wide range of harmful, dangerous, and unwanted contaminants and particles from the air.

To effectively use activated carbon filters in air purifiers, we would advise that:

• Make sure it uses enough carbon. Some filters claim to be activated carbon filters but use only a trace of carbon. These will not be effective because they become saturated almost immediately.
• Air flow is vital. To remove the most pollutants possible from the air, the air needs to spend the maximum possible amount of time passing through the carbon. A filter with a good amount of carbon of sufficient thickness and high dwell time is going to be far more effective than a filter with a thin layer of carbon.

• Change your carbon filter. The carbon becomes saturated depending on how heavily it is used and the amount of pollutants it is exposed to. Once the carbon becomes saturated, it loses all effectiveness as an air filter. When this happens, you must change it out for a fresh carbon filter.

Carbon’s ability to purify water and air has a remarkable history. After you have considered how carbon air filters work and when they are effective, you can decide which type of air purifier is appropriate for your situation and budget.

Engaging with a reliable and trusted air filter company is equally crucial, especially for commercial and industrial spaces, which have the most odour challenges.
