Indoor air quality (IAQ) is crucial for good health, especially for those with chronic respiratory diseases like fibrosis. Pulmonary fibrosis, a progressive condition, damages and scars lung tissue, causing significant breathing challenges. Due to the heightened sensitivity of fibrosis patients to airborne pollutants, high IAQ is essential. This blog examines the effects of substandard IAQ on fibrosis sufferers, underscores the necessity of frequent air quality assessments, and outlines strategies to enhance IAQ.
Understanding Pulmonary Fibrosis
Pulmonary fibrosis is a condition characterised by the thickening and scarring (fibrosis) of the lung tissue. This scarring results in stiffness in the lungs, making it increasingly difficult for oxygen to pass into the bloodstream. Symptoms of pulmonary fibrosis include:
- Shortness of breath
- Chronic dry cough
- Fatigue and weakness
- Chest discomfort
- Loss of appetite and weight loss
The exact cause of pulmonary fibrosis can be unknown (idiopathic), or it can be triggered by environmental factors, infections, medications, or other diseases.
The Impact of Poor Indoor Air Quality on Fibrosis
For those suffering from pulmonary fibrosis, it is crucial to maintain clean and healthy air. Poor indoor air quality can worsen symptoms, hasten the progression of the disease, and result in serious health issues. The main pollutants that affect indoor air quality and their particular effects on pulmonary fibrosis are as follows:
Particulate Matter (PM2.5 and PM10)
Particulate matter (PM) consists of solid particles and liquid droplets in the air. PM2.5, which are particles less than 2.5 micrometres in diameter, and PM10, particles less than 10 micrometres, can deeply penetrate the respiratory tract, leading to inflammation and impaired lung function. Research indicates that exposure to particulate matter correlates with higher rates of hospital admissions and mortality among people with chronic respiratory conditions, such as pulmonary fibrosis.
Volatile Organic Compounds (VOCs)
Volatile organic compounds (VOCs) are chemicals that readily evaporate into vapors or gases. They are present in numerous household items such as paints, cleaning agents, and air fresheners. VOCs can aggravate the respiratory system and lead to chronic inflammation, posing a significant risk to those with pulmonary fibrosis. Benzene, formaldehyde, and toluene are among the common VOCs.
Mould and Microbial Volatile Organic Compounds (mVOCs)
Mould, along with its by-products known as microbial volatile organic compounds (mVOCs), can provoke allergic reactions and exacerbate respiratory conditions. The presence of mould spores and mVOCs may result in symptoms like coughing, wheezing, and shortness of breath. In those with pulmonary fibrosis, mould exposure can greatly deteriorate lung function and overall health.
The Importance of Testing Indoor Air Quality
Regular indoor air quality testing is crucial for detecting and reducing harmful pollutants. Such testing can ascertain the levels of different contaminants and inform the appropriate measures to enhance IAQ. The following are the primary advantages of consistent air quality testing:
Early Detection of Pollutants
Early identification of harmful substances is crucial for taking timely measures to minimize exposure and prevent health decline. For those with pulmonary fibrosis, promptly detecting pollutants such as particulate matter, volatile organic compounds (VOCs), and mold is key to managing symptoms and halting the progression of the disease.
Improved Health Outcomes
Ensuring clean air is crucial for managing symptoms and enhancing life quality for individuals with fibrosis. Minimizing exposure to harmful pollutants can lead to reduced respiratory issues, fewer hospital admissions, and improved general health.
Informed Decision-Making
Data from air quality tests can guide decisions on implementing air purifiers, enhancing ventilation, and making lifestyle changes to reduce pollutant sources. This information is crucial for creating a safer and healthier living environment for individuals with pulmonary fibrosis .

Effective Strategies for Improving Indoor Air Quality
Several strategies exist to enhance indoor air quality and safeguard individuals with pulmonary fibrosis from detrimental pollutants. These strategies encompass:
Use of High-Efficiency Air Purifiers
High-quality air purifiers are effective in reducing indoor levels of particulate matter, VOCs, and other pollutants. When choosing an air purifier, it’s important to consider the following features:
- Activated Carbon Filters: Air purifiers with activated carbon filters are highly effective at adsorbing VOCs and other gaseous pollutants. For maximum effectiveness, choose a unit with at least 15 pounds of activated carbon or an equivalent amount of high-capacity adsorbent material.
- HEPA Filters: High-efficiency particulate air (HEPA) filters are designed to capture particulate matter as small as 0.3 micrometres. This makes them highly effective at removing PM2.5 and PM10 from the air.
- Air Exchange Rate: Ensure the air purifier has an adequate air exchange rate (measured in cubic feet per minute, or CFM) for the size of the room. This ensures that the air is thoroughly cleaned multiple times per hour .
Enhancing Ventilation
Adequate ventilation is key to lowering the levels of indoor pollutants. Enhancing the circulation of air between indoor and outdoor spaces can help in diluting and eliminating these contaminants from indoor areas. Below are some methods to enhance ventilation:
- Open Windows and Doors: Regularly opening windows and doors can significantly increase airflow and reduce the concentration of indoor pollutants.
- Use Exhaust Fans: Installing and using exhaust fans in kitchens, bathrooms, and laundry rooms can help remove contaminated air.
- Install a Mechanical Ventilation System: Systems such as heat recovery ventilators (HRVs) or energy recovery ventilators (ERVs) can provide continuous fresh air exchange while minimizing energy loss .
Controlling Humidity
It is crucial to keep indoor humidity levels under 50% to inhibit mould development and minimize respiratory problems. Employ dehumidifiers in moist areas like basements and address any leakage or water damage quickly to manage humidity effectively.
Regular Cleaning
Maintaining a clean living environment by eliminating dust, mold, and other allergens is essential for good indoor air quality. It’s important to vacuum carpets and upholstery regularly with a HEPA filter-equipped vacuum, wipe down surfaces with a damp cloth, and wash bedding often.
Persistent Chemical Residues
A major concern with chemicals such as naphthalene, present in certain mothballs and air fresheners, is their capacity to permeate building materials, fabrics, and various surfaces. Consequently, even after the chemical’s source has been eliminated, the remaining naphthalene can persist in off-gassing and remain detectable in the environment.
Strategies to Address Residual Contamination
- Thorough Cleaning: Clean all surfaces, fabrics, and ventilation systems to remove any residual chemicals.
- Sealing Surfaces: Applying sealants to porous surfaces, such as walls and floors, can help encapsulate any remaining contaminants and prevent them from off gasing.
- Ongoing Air Purification: Continue using air purifiers to capture any residual VOCs that may still be present in the environment .
Special Considerations for Individuals with Multiple Chemical Sensitivity (MCS)
Individuals with Multiple Chemical Sensitivity (MCS) frequently have increased reactions to low concentrations of chemicals such as naphthalene and volatile organic compounds (VOCs). For them, minimizing chemical exposure is particularly crucial.
Recommendations for MCS Patients
- Strict Chemical Avoidance: Implement strict avoidance measures, removing all potential sources of VOCs and naphthalene from the living environment.
- Enhanced Ventilation and Air Purification: Use enhanced ventilation systems and high-capacity air purifiers with activated carbon and HEPA filters to maintain the cleanest possible air.
- Regular Health Monitoring: Regularly monitor health and air quality, adjusting mitigation strategies as needed to ensure the living environment remains safe and comfortable .
