Greetings, new here. My asthma is exceedingly intermittent – I can go months with no problems, but then relapse very badly for a few weeks, I often experience a setback at this time of year (early winter). I live in Montreal and it has been very cold, and that may be a problem. Anyway, my question concerns dust buildup on those old-fashioned radiators – the ones from decades ago that have about a million nooks and crannies. My new apartment has these radiators and I just discovered they are packed – and I mean really packed – with dust. The quantities are mind-boggling, actually. And I believe dust mites can be a problem for me. However, much of the dust cannot be accessed for removal (I suppose I could use high-pressure water and clean up the muddy mess), On the other hand, given that this dust is embedded in a radiator, and that my apartment is very dry, perhaps the dust is too dry and hot to harbour mites. Any thoughts? – Could hot, dry dust packed into the crevices of a radiator be a problem for an asthmatic?
