In a previous article we discussed the very varied forms of indoor air pollution. Among these forms, microorganisms, and in particular moulds, are one of the main air pollutants.
In France, the national "Housing" campaign carried out between October 2003 and December 2005 by the Observatoire de la Qualité de l'Air Intérieur (OQAI) in nearly 600 dwellings revealed that about 40% of the residential stock was contaminated by mould, which represents more than 9 million dwellings nationwide, of which more than 610,000 had visible contamination of more than 1m². mould, which represents more than 9 million dwellings nationwide, among which more than 610,000 had visible contamination of more than 1m².Source
Mold is a living organism, specifically a microscopic fungus that often grows when moisture is present and causes a chemical reaction where it grows.
Mould is often noticeable by its black or green patches as well as a musty smell. Mould emits spores in large quantities. The spores are the pollen of the mould, i.e. particles that spread through the air and allow the mould to grow. in the air and allow the mould to grow. Spores are small, in the micrometre range, and move easily through the air.
To get into your home, spores use humans, including deposition on clothing, and all other available "vehicles" such as drafts and animals. Once in your home, moulds use these spores again to proliferate throughout your home. The spores grow quickly, especially in moist environments, and are very resilient. These spores are a real air pollutant, which is why it is generally considered These spores are a real air pollutant, which is why it is generally considered that moulds are one of the main sources of indoor air pollution.
Mould needs moisture to grow. Certain situations are favourable to them:
These moulds are most often found on walls, drywall, furniture, wallpaper, and degrade them.
Mould can therefore have adverse effects on your health. To diagnose you, your doctor may ask you to identify the variety(s) of mould present in your home. There are very many varieties of moulds. Here are the most common in mainland France:
If you have identified mould in your home, the first thing you need to know is what is causing it: damp? Water leakage? Try to treat the source of the problem.
When it comes to removing mould, if the affected area is small, you can remove it by scrubbing, using an all-purpose cleaner, diluted soap or detergent. Dry well after cleaning. Keep hard-to-clean objects away from the area. If the mould covers a large area, more than 1m² for example, you may need to call in a specialist building moisture treatment company.
When cleaning up your mould, be careful not to add pollutants to pollutants!
It is important to pay attention to mould and not leave it lying around. Take care of it!
Some tips to make sure you never run into a nasty surprise:
Spores can withstand extreme conditions, be vigilant!
Humidity, mould, pollution, all contribute to unhealthy air. Why should you breathe polluted and dangerous air when you are at home? TEQOYA has answered this question by creating a TEQOYA has answered this question by creating a range of air purifiers based on negative ions that will purify up to 99% of polluting particles. They consume virtually nothing and make no noise. These ionisers will help you feel better in your home, without the clutter. Your TEQOYA purifier will help you fight the spread of mold, by limiting the airborne movement of spores. Preventing yourself from polluted air means taking care of your health.
