MVHR Air Intake Filter Research

I follow a number of green building folks on Twitter and a recent Tweet from Kate de Selincourt alerted me to a research study that is looking at long-term changes in pollution and air quality by analysing MVHR intake filter samples from buildings in different locations. I presume the focus is on particulate pollution since I don’t expect NOx will leave any trace on the filter.

The research is being done by Claire Jamieson at Phi Architecture in conjunction with the Buildings, Energy and Environment Research Group at Nottingham University and the Green Building Store. There’s more information about the study and a sign-up form here.

I think this is a great idea since the filters are collecting the samples anyway and are normally just thrown away. I’m looking forward to seeing the results of the research, which they say will be published annually.

  1. The filters are on a 120-day change schedule (i.e. they get swapped 3 times a year) which for ease of remembering starts on 1st January. They were therefore ready for a swap at the end of April. I forgot to take a photo of the used intake filter before cutting out the two 40mm x 100mm samples for the research but it didn’t seem too dirty this time and I reckon it could have run for longer. The filters definitely seem to get dirtier over the summer – especially with the dust from the arable harvest in the surrounding fields, although maybe if that was vacuumed out it would help.
