Kuopion yliopiston ja Kuopion ty\u00f6terveyslaitoksen tutkijat selvittiv\u00e4t neulal\u00e4mm\u00f6nsiirtimen kyvyn est\u00e4\u00e4 suodattimen kosteutta ja mikrobivaurioita.<\/p>\n

Neulal\u00e4mm\u00f6nsiirrin sijoitettiin tutkimuksessa ennen tuloilmasuoda\u00adtinta. Suodattimen suhteellista kosteutta ja l\u00e4mp\u00f6tilaa seurattiin jatkuvasti kolmessa pisteess\u00e4: 1) ulkoilma, 2) suodatin ja 3) sis\u00e4ilma, noin vuoden ajan.<\/span><\/p>\n

Suodattimen suhteellinen kosteus pysyi kaikkina vuodenaikoina alle 70 %:ssa ja l\u00e4mp\u00f6tila yli 3 \u00b0C:een. Suodatin pysyi kuivana koko k\u00e4ytt\u00f6ik\u00e4ns\u00e4, my\u00f6s lumipyryjen aikana, mik\u00e4 v\u00e4hensi vaihtotarvetta. Kosteissa oloissa viihtyvien mikrobien pitoisuudet ja lajim\u00e4\u00e4r\u00e4 olivat suodatinkammiossa pienemm\u00e4t kuin l\u00e4mm\u00f6nsiirtimess\u00e4, eli neulal\u00e4mm\u00f6nsiirrin esti ulkoilman mikrobien levi\u00e4mist\u00e4 p\u00e4\u00e4suodattimeen.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
