What Are Mould Spores?
Mould spores are tiny reproductive fungal cells that float through the air as microscopic particles looking for a favourable environment to establish new mould colonies. These spores can affect the airways and lungs, potentially causing serious illness, especially for those with existing respiratory conditions. Mould spores stay airborne indefinitely. While in the air, they remain dormant until they come into contact with wet or moist surfaces, at this point, they may start growing into visible mould.

The Issue Posed By Mould Spores
In England, 3-4% of the nation’s four million social homes suffer from significant levels of dampness and mould, with many homes classified as having category three hazards. The problem is particularly concerning because, according to the NHS, treating illnesses linked to damp and mould could save the health system as much as £38 million annually, if damp issues were properly addressed.
A recent report revealed the extent of this issue in the social housing sector, highlighting that millions of people live in homes impacted by mould and dampness, contributing to both physical and mental health problems. More proactive measures must be taken to tackle this growing issue, which affects not only the quality of life but also public health and safety.

How Mould Spores Affect Health
While mould spores are typically present in very low concentrations, they can be dangerous for sensitive individuals, particularly those with respiratory issues, allergies, or weakened immune systems. The most common health complaints associated with mould exposure include:
- Respiratory problems
- Allergic reactions (sneezing, coughing, itchy eyes)
- Skin irritation
- Sinus congestion
- Worsening of asthma and other respiratory conditions
Therefore, reducing exposure to mould spores in the air is essential for maintaining a healthy living environment.
How To Remove Mould Spores From The Air
To protect premises, it’s important to address the root cause of mould and take steps to reduce the concentration of mould spores in the air. Here are some effective strategies:
1. Using Air Purifiers
Air purifiers are one of the most effective ways to eliminate mould spores from the air. These devices draw in contaminated air and pass it through specialised filters which have been designed to capture and remove microscopic particles, including mould spores.
Our VIRUSKILLER™ air purifiers are equipped with state-of-the-art technology, including a triple filtration system and an inbuilt UV-C reactor chamber, providing an all-in-one solution that purifies the air, neutralises toxins, and decontaminates the environment. When independently tested against Coronavirus DF2 (a surrogate for Coronavirus), Adenovirus, Influenza and Polio, the unit was found to kill 99.9999% of viruses on a single air pass.
2. Improving Ventilation
Increasing ventilation inside a building reduces the build-up of mould, especially if the problem is related to moisture. Allowing stale, damp air to escape and fresh air to circulate, creates a healthier indoor environment.
3. Fixing the Conditions That Lead to Mould Growth
Preventing mould from growing in the first place is the best way to limit airborne spores. Common causes of indoor mould include:
- Plumbing leaks
- Roof leaks
- Flooding
- Excessive humidity
- Condensation
- Moisture control is key to mould prevention. Even small amounts of moisture can lead to the germination and growth of mould spores, so it’s essential to address any water-related issues promptly.
