Filter the air

Air filtering is necessary in Net Zero Energy Buildings, where hermetically sealed construction prevents building ventilation. Poor indoor air quality (IAQ), with levels of pollutants like CO₂, VOCs, and particulate matter that escalate without adequate filtration, may also impact the health of occupants.

Best Option

A Mechanical Ventilation with Heat Recovery (MVHR) system is a solution to this challenge.

 

How it works

MVHR works by continuously removing humid air from wet rooms (e.g., kitchens, bathrooms) and supplying clean, fresh air to living areas. This enhances indoor air quality while minimising energy loss and costs. 

Functions

  • Pollutant removal: MVHR technology filters out airborne pollutants, pollen and dust from incoming air.

  • Economic savings through heat recovery: MVHR systems recover up to 90% of heat from the exhausted air, providing thermal comfort without raising heating loads.

  • Steady flow of fresh air: In contrast to intermittent systems that cycle on and off, creating peaks of pollutant concentration.

  • Supports airtight construction: MVHR can complement airtight building envelopes by providing ventilation without needing leaky structures
