[Ucol-shareholders] just cleaned the filters in the air exchange units - Tim, are there more on the way?

Hi everyone I just cleaned the air exchange filters, easy to do (with a vacuum cleaner), they slide out of the main unit in the attic. One filter takes air from the wet areas and (so Catherine tells me) the air is immediately expelled outside, this was pretty dirty. The other was dusty. They are just made of paper and, if we had some spares, we would replace the wet area one now. Tim said he ordered a 'box' and they sent him a box of 2!  Can Toiora order a bulk lot? CheersJeffrey
