An article in the UK newspaper The Guardian last January describes a series of tests in homes with wood burning stoves with some quite alarming results as regards to levels of PM 2.5 .One of the criticisms, made by a UK woodstove manufacturer, was that the test equipment was cheap & basic. the enviro + run with a Raspberry Pi together with the PMS5003 Particulate Matter Sensor costs only about €85.00 it's maximum operating temp is 60c & the unit doesn't come with a probe or any way of filtering so not really a viable alternative to a Testo. What do folks think about this ? Has anyone measured PM 2.5 in the room with a rocket stove ? my thoughts are that positive pressure & the way our stoves are loaded, after or during coaling reduce the possibility of smoke coming out.Conventional woodstoves have become enormously popular the last few years in the UK, my former colleges in tree surgery are making a lot more money on firewood.A good deal of these stoves are in urban ,middle class homes & are more of a lifestyle choice than an alternative to high fuel prices.Having said that the finger pointing police seem to be going after stoves in the same way that 4x4 drivers were once targeted.

I did some work with the plantower looking at flue gas particulates. For living spaces, HEPA is a good investment, even if you are not burning wood. For the DIY crowd, you can make a really good air filter using MERV 13 filters and a box fan. Quite a lot of research has gone into them recently, they test well. The web site cleanaircrew.org has detailed instructions on how to make the various versions. PM 2.5 are best avoided.

Most of the fine ash particulates in houses come from removing ashes or opening the stove door. I've found that if I always open the bypass and stove door at the same time I get almost no fly ash coming out then. Removing the ashes is where the majority of it comes from, that's what made me design an ash-trap into my stoves, with that and a good drawer sized ash-box underneath, you can just lift out the ash-box and take it out the house without aerosolizing any of it indoors.
