Controlled air extraction for healthy indoor environments
In residential buildings, improved insulation and airtightness reduce natural air exchange. Without proper ventilation, moisture, pollutants and odours can accumulate, affecting both indoor comfort and building performance.
MEV supports a healthy indoor climate while offering a practical and cost-effective approach to residential ventilation.
How MEV systems work
MEV system is based on central mechanical extraction. Air is continuously removed from wet rooms, creating a slight negative pressure inside the dwelling. This allows fresh outdoor air to enter naturally through ventilation inlets and flow through the home towards the extraction points, ensuring continuous air renewal.
This controlled airflow helps maintain indoor air quality without the need for a mechanical supply system.
When MEV is the right solution
MEV systems are particularly well suited to existing housing and renovation projects. In situations where space is limited or where a full balanced ventilation system is not required, MEV offers a practical and efficient alternative.
It is also an excellent solution for upgrading or replacing older ventilation systems, providing improved performance with minimal disruption during installation.

Comparing MEV and MVHR ventilation systems
| | MEV | MVHR |
|---|---|---|
| How it works | Extracts stale and humid air. Fresh air enters through air vents. | Extracts stale air and supplies fresh air with heat recovery. |
| Best suited for | Renovation projects, existing homes and cost-effective solutions. | New-build, well-insulated and airtight homes. |
| Benefits | Cost-effective, easy to install, helps prevent damp and mould. | Energy-efficient, reduces heating costs, improves comfort and indoor air quality. |
| Energy efficiency | No heat recovery. | Heat recovery reduces energy consumption. |
Frequently Asked Questions
What is MEV?
MEV (Mechanical Extract Ventilation) is a ventilation system that continuously extracts stale, humid air from wet rooms such as kitchens, bathrooms and toilets.
Fresh air enters the home through background air vents.
When should I choose an MEV system?
MEV is ideal for renovation projects, existing homes and situations where a simple, cost-effective ventilation solution is required.
Does MEV recover heat?
No. Unlike MVHR systems, MEV does not recover heat from the extracted air. Fresh air enters naturally through air vents.
Is MEV suitable for modern homes?
Yes. MEV is suitable for many residential applications, particularly where heat recovery is not required or practical. It provides reliable, continuous ventilation to help maintain a healthy indoor environment.
Why choose Ubbink for an MEV system?
Ubbink offers a complete MEV ventilation solution with compatible components designed to work together. From system design with Aerflux to straightforward installation, Ubbink helps simplify every stage of your ventilation project while delivering reliable indoor air quality.
