Zehnder Group UK has introduced its range of specialist NOx filters, in order to help customers meet important Indoor Air Quality (IAQ) targets especially in consideration of rising NO₂ levels.

The filters will also help to reduce symptoms of respiratory illness in regions with high levels of air pollution, typically inner cities and urban areas. With IAQ and ventilation inextricably linked, the filters are used in conjunction with a Mechanical Ventilation with Heat Recovery (MVHR) strategy as part of the ‘Whole House’ ventilation approach, widely recognised to improve IAQ and increase health benefits for residents.

Zehnder’s NOx filters provide high grade filtration to meet Air Quality Planning Regulations requirements and are available in five options to suit all MVHR models. The filters are also compact in size, in order to minimise energy consumption, and have a lifespan of 2-5 years.

Zehnder’s NOx filters also include a feature unique to the market: an integrated maintenance site panel. Each unit has a perspex panel which provides a quick view of the filter cartridge status when it is installed, rather than requiring access to the filter as is standard with other filters on the market. This eliminates the need to remove the entire front panel and saves time and labour on site.
