Is Your Home a Secret Breeding Ground for Mould? Here’s How to Find Out
Share
Mould is a silent invader that can cause serious health issues and costly home repairs if left unchecked.
In Singapore, the average yearly relative humidity is around 84%—much higher than the ideal indoor level of 47%. This excess moisture can make your living space feel uncomfortably sticky.
Often triggered by excess humidity, mould can thrive in places you’d least expect, quietly affecting your living spaces.
In this guide, we’ll show you how to spot mould-friendly environments and protect your home from damage.
How to spot excess humidity in your home
High humidity is the main culprit behind mould growth. The signs can be subtle, so here’s what to look out for:
1. Condensation on windows
Seeing water droplets on your windows, especially in the morning? That’s a red flag. When warm, humid air meets cooler windows, condensation forms. This moisture can seep into your window frames, encouraging mould.
2. Musty odours
A damp, musty smell is often mould’s calling card. If certain areas of your home—like the basement, bathroom, or attic—have a persistent odour, mould could already be growing there, even if you can’t see it yet.
3. Water stains
Discolored patches on walls or ceilings can signal moisture issues. These spots often hide mould colonies behind the surface, so don’t ignore them.
4. Peeling paint or wallpaper
Bubbling wallpaper or peeling paint? Trapped moisture could be to blame. This not only looks bad but also creates a perfect breeding ground for mould.
5. Damp carpets or floors
If your floors feel damp, especially in basements or other high-humidity areas, there’s a chance mould spores are settling into the fibers or wood.
How dehumidifiers can help
If you’ve noticed any of these signs, don’t panic—there’s a simple solution: a dehumidifier. Here’s why having one in your home can make a big difference:
1. Control humidity levels
Dehumidifiers help maintain an optimal indoor humidity level (between 30-50%). By keeping moisture under control, you reduce the risk of mould, dust mites, and other allergens. For example, placing a dehumidifier in moisture-prone areas like bathrooms or basements can make a huge difference.
High-performance models like NNIO’s feature a built-in humidity sensor that automatically adjusts to the right level, giving you that "set-it-and-forget-it" convenience.
2. Boost air circulation
Stale air traps moisture, which mould loves. Dehumidifiers improve circulation by pulling in humid air, removing excess moisture, and circulating dry air back into the room. With options like an air circulator, you can even customize airflow settings for better results.
3. Protect furniture and fabrics
Wood furniture and fabrics are especially vulnerable to humidity. Moisture warps wood and allows mould to form on upholstery. A dehumidifier keeps these surfaces dry, protecting your home and extending the lifespan of your furniture.
4. Prevent mould in HVAC systems
Your heating, ventilation, and air conditioning (HVAC) system could be spreading mould throughout your home. Condensation inside ducts can lead to mould growth, so place a dehumidifier near your HVAC intake to keep the air dry and your system mould-free.
5. Reduce allergens
By removing excess moisture, dehumidifiers create a less hospitable environment for allergens like dust mites and mould spores. This improves air quality, which is especially important for anyone with asthma or allergies.
Extra tips for reducing humidity
While a dehumidifier is a powerful tool, there are other simple ways to control moisture in your home:
- Ventilate properly: Ensure your home is well-ventilated, especially in moisture-heavy rooms like the bathroom and kitchen. Use exhaust fans when showering or cooking to remove steam.
- Fix leaks quickly: Don’t let small leaks turn into big problems. Fixing plumbing or roof leaks immediately can prevent moisture buildup.
- Use moisture absorbers: Place products like silica gel or charcoal in closets or cupboards to absorb moisture in closed spaces.
