recently purchased the Pure Enrichment® MistAire™ Silver Ultrasonic Cool Mist Humidifier (1.5L capacity). I used it last night for the first time. Set-up was quick and easy. I love that you can run it without the power button lit up if you choose. (More electronic manufacturers should do that.) It’s extremely quiet. But most importantly, the humidifier really helped add moisture to the air in my room. We have natural gas heat. When the weather is really cold, I wake up in the night when the heater kicks on because the air gets so dry it irritates my airway. Last night, the humidifier kept my room just right and I did not wake up when the furnace was running. Works great. Would recommend.
