With a growing body of research pointing to the health implications of poor indoor air quality (IAQ) in our homes, British ventilation manufacturer Vent-Axia has set the benchmark for high-level filtration with the launch of the Vent-Axia Pure Air.
Designed specifically to answer the needs of the new build residential market, this indoor air quality filtration system has been developed to work in conjunction with Mechanical Ventilation with Heat Recovery (MVHR) units to offer the ideal indoor environment.
MVHR extracts harmful pollutants and allows the air coming into the home to be filtered, taking out airborne bacteria and dangerous contaminants. The filter, working with the MVHR system, is fitted to the intake airflow and incorporates two types of filtration—activated carbon and G4/F7 particulate filters.
Offering housebuilders a choice of filtration to suit the application, the Vent-Axia Pure Air is available with G4 or F7 particle filters. G4 filters can remove up to 90% of the PM10 particles in the air, including some bacteria, most pollens and many types of industrial dust. Meanwhile, the finer F7 filters are ideal for inner city areas with heavy traffic since they remove up to 80% of the tiny PM2.5 particles, this includes fine diesel particulates.
Meanwhile, enhanced activated carbon filtration removes odours and harmful gases such as Nitrogen Dioxide (NO²). High levels of NO² can cause respiratory problems and increased incidences of asthma. The Vent-Axia Pure Air filters incoming air, designed to meet World Health Organisation guides for NO².
A raft of research has recently reported the importance of good IAQ and how the nation’s health is dependent on it. Earlier this year the Royal College of Physicians published the report ‘Every breath we take: the lifelong impact of air pollution’ revealing how air quality affects health and it has been proven that poor IAQ is a particular health risk.
The filters are available in different sizes for use in properties from small apartments to large offices. The size of the filtration system needed is determined by the required airflow of each application. Plus the Vent-Axia Pure Air also has a range of rectangular and round spigot options, including combinations of both. The filter unit can be installed vertically or horizontally and fit a multitude of MHVR configurations.
The particle filters conform to EN 779 and combined with specially formulated gas filters help meet IAQ levels conforming to EU Directive 2008/50/EC. In addition, the Vent-Axia Pure Air is designed to improve indoor air quality and comfort for occupiers and so external noise is attenuated as it passes through the unit thus reducing induct noise and helping to achieve specified sound levels in dwellings.
