Evaporative humidifiers

Hello all! I recently read on the NTMir website that Dr Falkinham recommends using an evaporative humidifier only, as tests have shown that the wicking filters effectively filter out NTM. I'm wondering if any of you have used this type of humidifier. I've read reviews online but I'd rather hear it from my peers who have the same concerns. I'm looking for one that ideally has a washable filter so I won't have to endlessly fork over money to replace it. I live in the desert so the air is dry and dusty year-round. Please help if you can! Thanks!
