Bellew Environmental, Specialist Environmental Consultants, reported the following after testing Volatile Organic Compound (VOC) emissions on Diesel vehicles.
The conclusions based on the analysis have shown that significant reductions are recorded with the change from old used filter to new filters. These reductions are further increased using the Boreas Air wrap, with the Boreas Filter allowing for the most significantly reduced VOC’s in all samples analysed. Some machines have shown greater improvements than others however the reduction in all samples indicated that vehicles should be maintained and where possible use the Boreas Air Filter to further reduce VOC emissions giving the best possible result.
The study has shown that there can be significant environmental savings generated using the Boreas Air product. This is an important factor in the monitoring of machines on sites and particularly in large cities where the significant reduction of air pollution is now the target of many governments through the implementation of Euro 5 and now Euro 6.

There are current trials in progress to test the hypothesis that the Boreas air filter can generate Fuel savings and as a direct result financial savings. Some of the trial clients have already generated savings.
A large haulage operator, monitor fuel efficiency rigidly. Upon installation of Boreas Air filters the company have saved 9%, in the week beginning 03.04.2017 and 7% in the week beginning 27.03.2017. These figures are based on the data from one lorry.
A1 generators tested a loaded 26 KVA generator. The Generator was filled with 1/2 half litre of fuel with an unprotected air filter, the duration of service was 13 minutes, the machine was then tested again with ½ litre of fuel however the second time the filter was protected with Boreas Air, the duration of service was 19 minutes. This was 6 extra minutes of service on ½ fuel using the BoreasAir.
Mr Woods Van Toyota Hiace is generating a 14% Fuel Saving, monitored over the last Month.
David Mc Keown has found using the Boreas Air Filter compare with the standard air filter, that he is generating a 14% Fuel Saving on his fleet of Toyota Hiace Vans.
Bellew Electrical Wholesale Ltd have trialled the Boreas Air Filter on one Van over a two week period. Savings generated on this Vehicle were 10% over the 2-week period. Bellew Electrical are rolling the product installation out across the fleet.
