Home Air Quality Assessments

Home Air Quality Testing»

Our comprehensive home air quality assessments evaluate a wide range of indoor environmental factors, including temperature, humidity, particulate matter (PM2.5 and PM10), volatile organic compounds (VOCs), carbon dioxide (CO2), nitrogen dioxide (NO2), ozone (O3), formaldehyde (HCHO), and carbon monoxide (CO).

Specialised Testing

Mould Testing»

Our specialised mould testing services for residential properties involve the detection and identification of mould growth. We use advanced techniques to assess the presence, type, and extent of mould, enabling homeowners to take prompt action to address the issue and mitigate any health risks associated with mould exposure.

Radon Testing»

 Radon, a naturally occurring radioactive gas, can pose significant health risks if present in high concentrations in homes. Our radon testing services evaluate the levels of this gas in residential properties, allowing homeowners to implement necessary mitigation measures and ensure the safety of their living environment.

Allergens In The Air Testing»

We conduct specialised testing to measure the presence and concentrations of common indoor allergens, such as pollen, pet dander, and dust mites, in homes. This helps identify and address the sources of these allergens, creating a more comfortable living environment for occupants with allergies or respiratory conditions.

VOC and Formaldehyde Testing»

Our assessments evaluate the levels of volatile organic compounds (VOCs) and formaldehyde within residential settings. By identifying the presence and potential sources of these indoor air pollutants, we can provide recommendations to mitigate the health risks and improve the overall indoor air quality.

What's in the air you breathe

Particles and Humidity

Particulate matter refers to tiny solid or liquid particles suspended in the air.

These particles can vary in size, from larger ones (PM10) like dust and pollen to ultrafine particles (PM2.5) that can penetrate deep into our lungs.

Sources of PM include vehicle emissions, industrial processes, and even indoor activities like cooking or burning candles. Exposure to PM can lead to respiratory issues, worsen asthma symptoms, and even impact cardiovascular health. To mitigate PM levels, proper ventilation, air filtration, and minimising indoor sources are essential.

Allergens are substances that trigger allergic reactions in sensitive individuals.

Common indoor allergens include pollen, pet dander, dust mites, and mold spores. When inhaled or touched, these allergens can cause sneezing, itching, watery eyes, and exacerbate asthma symptoms. Effective control measures involve regular cleaning, using allergen-proof bedding, and maintaining optimal humidity levels to reduce exposure.

Viruses are microscopic infectious agents that can survive in the air.

In indoor environments, airborne viruses (such as influenza or SARS-CoV-2) spread through respiratory droplets.

Ventilation and air purification are crucial for virus control.

Mould is a type of fungus that thrives in damp conditions. When moisture is present, mould spores can grow on surfaces like walls, ceilings, or even hidden areas.

Exposure to mould spores can cause allergies, respiratory irritation, and worsen asthma symptoms. Preventive measures include promptly addressing moisture issues, improving ventilation, and removing visible mould.

Humidity refers to the moisture content in the air. Maintaining an ideal relative humidity level of 40-60% indoors is crucial.

High humidity encourages mould growth, while low humidity can lead to dry skin, irritated eyes, and respiratory discomfort. Using dehumidifiers or humidifiers helps regulate indoor humidity.


CO₂ is a colourless gas produced by human respiration and combustion processes (such as burning fossil fuels).

Elevated CO₂ levels indoors can affect cognitive function, concentration, and overall comfort. Proper ventilation ensures fresh outdoor air circulation, maintaining safe CO₂ levels.

Volatile Organic Compounds (VOCs) are chemicals emitted from various indoor sources, including paints, cleaning products, furniture, and carpets.

These compounds can impact both health and indoor air quality, including liver damage, lung damage and cancer in serious cases

Strategies to reduce VOC exposure include using low-VOC materials, proper ventilation, and choosing products with minimal emissions.

Formaldehyde is a common indoor pollutant found in building materials, furniture, and household products.

Prolonged exposure to formaldehyde can cause respiratory irritation, headaches, and other health issues.

Proper ventilation and selecting low-formaldehyde products are essential for minimising exposure.

 Ozone is a gas formed by chemical reactions (e.g., from air purifiers or photocopiers).

While ozone high in the atmosphere protects us from UV radiation, indoor ozone can harm respiratory health. Limiting exposure to safe levels is crucial.

NO₂ is produced by combustion processes (e.g., gas cookers, vehicles). Indoor exposure to NO₂ aggravates respiratory conditions, especially in individuals with asthma.

Proper ventilation and minimising indoor combustion sources help reduce NO₂ levels.

Radon is a naturally occurring radioactive gas that seeps into buildings from soil and rock.

Long-term exposure to radon increases the risk of lung cancer.

Radon testing is crucial, especially in areas with high natural radon levels.

CO is a colourless, odourless gas produced by incomplete combustion (e.g., gas cookers, fireplaces, or car engines).

CO poisoning can be fatal. Installing CO detectors and ensuring proper appliance maintenance are essential safety measures.
