How to Remove Mould in Your Home with KERS+ Heat Recovery Ventilation

February 5, 20260

Mould in the home is more than just an unsightly nuisance — it’s a sign of excess moisture and poor ventilation, and it can negatively impact both your property and your health. Bathrooms with steamy showers, kitchens with daily cooking, and bedrooms with little airflow are common hotspots. While cleaning visible mould is important, the real solution lies in tackling the root cause: trapped humid air.

 

This is where KERS+ Heat Recovery Ventilation makes a major difference.

Why Mould Grows Indoors

Mould spores are naturally present in the air, but they only grow when conditions are right. The key ingredients are:

 

    • High humidity (typically above 60%)

    • Condensation on cold surfaces

    • Poor air circulation

    • Limited fresh air exchange

Modern homes, especially those upgraded for energy efficiency with insulation and airtight windows, often trap moisture inside. Everyday activities such as cooking, drying clothes indoors, and even breathing add litres of water vapour to the air each day. Without proper ventilation, this moisture settles on walls, ceilings, and window reveals — creating the perfect breeding ground for mould.

Why Cleaning Alone Doesn’t Work

Wiping mould off a wall with spray or bleach may remove stains temporarily, but if humidity remains high, it will return. True mould prevention requires continuous moisture control, not just surface treatment.

That’s exactly what KERS+ is designed to do.

How KERS+ Stops Mould at the Source

KERS+ is a single-room heat recovery ventilation system that provides constant fresh air while removing stale, moisture-laden air — all without losing the heat you’ve paid to produce.

 

1. Continuous Moisture Extraction

KERS+ units quietly extract humid air from rooms such as:

 

    • Bathrooms

    • Kitchens

    • Bedrooms

    • Utility rooms

kers+ removes damp stale air

By steadily removing moist air, the system prevents humidity from building up to mould-forming levels.

 

2. Fresh Air Supply Without Heat Loss

Unlike opening windows — which wastes heat and increases energy bills — KERS+ uses a ceramic heat exchanger to recover warmth from outgoing air and transfer it to incoming fresh air.

This means:

✔ You ventilate your home
✔ You control moisture
✔ You keep the warmth inside

A warm, well-ventilated home is far less likely to suffer from condensation and mould.

 

3. Humidity-Sensitive Operation

Many KERS+ models include humidity sensors that automatically increase airflow when moisture levels rise, such as during showers or cooking. Once humidity drops back to safe levels, the system returns to normal operation — ensuring ventilation happens when you need it most.

This smart control helps stop the damp conditions mould needs to grow.

 

4. Prevents Condensation on Walls and Windows

Condensation is often the first warning sign before mould appears. KERS+ reduces indoor humidity levels, meaning:

 

    • Less water collecting on window glass

    • Fewer damp patches on walls and ceilings

    • Reduced risk of black mould forming in corners and behind furniture

 

5. Improves Overall Indoor Air Quality

Mould releases spores that can trigger:

 

    • Allergies

    • Asthma symptoms

    • Respiratory irritation

 

KERS+ not only removes moisture but also filters incoming air, helping create a healthier indoor environment for your family.

 

Where KERS+ Makes the Biggest Impact

KERS+ is especially effective in:

🏠 Older homes with poor natural ventilation
🏠 Airtight renovated homes
🏠 Apartments without wall vents
🏠 Bedrooms prone to window condensation
🏠 Bathrooms with recurring mould on ceilings

Because it is decentralised (room-by-room), it can be installed exactly where mould problems occur.

 

Long-Term Mould Prevention, Not a Temporary Fix

Think of KERS+ as a permanent moisture management solution, not just a fan. By keeping air moving and humidity controlled all year round, it addresses the underlying cause of mould rather than just cleaning the symptoms.

Homeowners often notice:

✔ Fresher smelling rooms
✔ Dry windows in the morning
✔ Reduced damp patches
✔ No return of mould after treatment

 

Final Thoughts

Mould is a moisture problem — and moisture problems need ventilation solutions. KERS+ Heat Recovery Ventilation removes humid air, supplies fresh filtered air, and retains indoor heat, creating an environment where mould simply cannot thrive.

Instead of repeatedly scrubbing mould away, you can stop it from forming in the first place — and enjoy a warmer, healthier, fresher home all year round.
