Really glad you like our product. I will admit it is pretty expensive, but as you've said, your particle count will get to almost 98% of less than what was originally lurking in your rooms. That is nowhere near what other air purifiers can do. When I first joined the company, I was told not to put it on full blast the first night otherwise your mouth will become dry. It still blows my mind that people experience that. I keep mine on throughout the night as well, but I have definitely noticed the sound doesn't have the humming sound as opposed to other air purifiers. It is a much quieter, fan like sound.
