Envirovent EVL LoftVent MK2 Whole House PIV Unit
EnviroVent EVL LoftVent MK2 Whole House PIV Ventilation Unit Without Heater
Product Description
The EnviroVent EVL LoftVent MK2 is an energy-efficient, loft-mounted Positive Input Ventilation (PIV) system designed to improve indoor air quality, reduce condensation and help prevent damp and mould throughout the home. Ideal for houses and bungalows with accessible loft spaces, this whole house ventilation unit delivers a continuous supply of fresh, filtered air to create a healthier and more comfortable living environment.
Designed for installation in the loft, the LoftVent MK2 introduces filtered air into the property through a centrally positioned ceiling diffuser, typically located on a landing or in the main hallway. The gentle airflow helps dilute and displace stale, moisture-laden air, reducing humidity levels and minimising condensation on windows, walls and other cold surfaces.
Featuring an ultra-low-wattage brushless DC motor, long-life filters and an integrated hours run meter, the EnviroVent EVL provides reliable, quiet and economical ventilation. Its heater-free design makes it an ideal solution for homeowners seeking continuous whole house ventilation with minimal electricity consumption.

Energy-Saving Benefits
- Minimum Energy Consumption: The ultra-low-wattage brushless DC motor provides efficient continuous ventilation while keeping electricity usage low.
- Natural Solar Gain: Utilises air from the loft space, which can be naturally warmed by solar energy during daylight hours.
- Improved Heat Distribution: Helps circulate air throughout the property, supporting more even indoor temperatures.
- Reduced Window Opening: Provides fresh, filtered ventilation without relying solely on opening windows during colder weather.
- Economical Continuous Operation: Designed for everyday use with minimal power consumption.
- Long-Term Reliability: Durable motor technology and long-life filtration support efficient performance and manageable maintenance costs.
Condensation, Damp & Mould Control
Modern homes with improved insulation, double glazing and draught-proofing can experience restricted natural airflow. Without adequate ventilation, moisture generated by cooking, bathing, laundry and everyday activities can accumulate indoors, leading to condensation, musty odours, damp patches and mould growth.
The EnviroVent EVL LoftVent MK2 helps address these issues by introducing a continuous supply of filtered air into the living space. The resulting positive air pressure encourages stale, humid air to escape through existing ventilation routes, helping to maintain more balanced humidity levels.
By reducing excess moisture and improving air circulation, this PIV ventilation system helps protect internal surfaces from condensation and supports a fresher, more comfortable home.
Indoor Air Quality Benefits
- Helps replace stale indoor air with a continuous supply of fresh, filtered air.
- Reduces excessive humidity that can contribute to condensation and mould.
- Supports improved ventilation in well-insulated and draught-proofed properties.
- Helps reduce persistent musty odours associated with poorly ventilated spaces.
- Filters incoming air to help limit the entry of airborne particles.
- Promotes a fresher and more comfortable indoor environment throughout the year.
How the EnviroVent LoftVent MK2 Works
The EVL Positive Input Ventilation unit draws air from the loft space and passes it through long-life filters before gently distributing it into the home through a ceiling-mounted diffuser.
This continuous supply of filtered air creates a slight positive pressure within the property, helping to displace stale, moisture-laden air through natural leakage points and existing ventilation pathways.
The system operates quietly and efficiently, providing whole house ventilation without the need for an integral electric heater.
