My husband and I have used an air purifier in our bedroom for many years. It started making white noise while we slept; then we continued in the hope that it would help with the allergies. We've had two units with "cleanable" filters (which just need to be removed, vacuumed and replaced) but they turned out to be ineffective. My allergies are getting more and more annoying at night. After just one night on Mooka, we were both breathing better at night and in the morning. We switched it to level 3 (highest level) because the device is very quiet and we prefer white noise. (Level 1 is almost silent, while level 2 is still very silent.) I hope the filter lasts a while. It's nice that if you post a review of the device, they give you a free filter. It doesn't affect how I see it, but it's still beautiful.
