Got this purifier/humidifier combo a few months back, really liking it so far, it’s helped a little with my chronic sinus problems https://www.pricerunner.dk/pl/453-3388298875/Indeklima/Philips-AC3421-Sammenlign-Priser However, as others have said, a purifier is not a replacement for daily ventilation, and while it may absorb some mold spores, it also won’t fix a potential mold problem
