Titon Introduces Trimbox NO2 Filter For Improved Indoor Air Quality - March 2016
With pollution in cities and urban areas on the rise, Titon has developed the Trimbox NO2 Filter to complement its extensive range of HRV Q Plus Eco MVHR units to combat the high levels of Nitrogen Dioxide (NO2) found in exhaust gases from diesel engines. The Trimbox NO2 Filter incorporates balanced flow technology to provide class leading absorption of NO2 and is available in two duty sizes (depending on the duty required). The product is effective in reducing NO2 to an acceptable mean annual concentration level of 40µg /m3, while vastly improving indoor air quality (IAQ). Independent tests have demonstrated the Trimbox to absorb 95% of NO2 not only in normal, continuous ventilation mode but also at boost or higher ventilation rates.*
NO2 from road transport is estimated to be responsible for 50% of Nitrogen Oxides, with levels highest in urban environments and near too busy roads. In London alone, it is estimated that 9,500 people die each year because of air pollution.** Indeed, NO2 levels were in the headlines in February 2016, when research published by the Royal Colleges of Physicians and of Paediatrics and Child Health stated that ‘emissions from diesel engines have been poorly controlled and indoor air pollution has been overlooked.’*** Various indoor sources of NO2 were also identified, including gas cooking, solvents that slowly seep from plastics, paints and furnishings, as well as air fresheners. Air pollution has been linked to health issues including heart disease, lung problems and asthma.
However, the Trimbox NO2 Filter is highly effective in reducing pollutants in urban homes (including sulphur dioxide, hydrogen sulphide, hydrogen chloride and chlorine), improving IAQ and reducing the risk of Toxic Home Syndrome and the ailments associated with air pollution. The filter also performs well against ammonia odours. As with other impregnated grades of activated carbon, it will also adsorb the same contaminants as impregnated carbon, e.g. volatile organic compounds and solvents.
All products are low profile (205mm deep) enabling them to fit into small ceiling voids, where space is restricted. Duct connections are via either 220mm x 90mm, Ø150mm or Ø160mm, while units are also available with an optional thermal cover.
Compatible with Titon's entire range of MVHR units, the unit boasts a compact design and can be installed in both intake air and supply ducting. In addition, each product is fitted with a G4 pre or optional F7 filter, and either 3 or 4 carbon grade filters, depending on airflow requirements. The two units are designed for variable airflow, making them suitable for small to large dwellings.
Commenting on the new unit, Paul Cowell, Senior Technical Manager at Titon, said: "It is widely recognised that people spend the majority of their time indoors and now as a result there is a growing awareness of the importance of indoor air quality. Titon Eco MVHR units, fitted with the correct type of thermal bypass to comply with EU Regulations, when used in conjunction with the Trimbox NO2 Filter means that pollutants, and predominantly exhaust gases from diesel engines, can be effectively reduced."
Titon’s Trimbox NO2 Filter is manufactured from zinctec sheet steel, as well as powder-coated, compact and lined with closed cell foam for sound attenuation and condensation control. Measuring 690mm x 354mm x 205mm, the unit conforms to the EU Directive 2008/50/EC (the CAFE Directive) and to The Building Regulations Part F. Accessories including rectangular to round duct connectors, replacement pre-filters and active carbon filters, are also available.

* All performance data for the new filters has been derived by independent testing at a UKAS recognised test house. The testing regime was carried out to the World Health Organisation's and European Union standards. The test report concludes that: "Both filter units performed very well, with nitrogen dioxide filtration performances of approximately 95% being achieved".
