Negative Positive
Title: noisy, worked a few times
Review: i only used it a few times. it is not quiet enough to sleep near...unless you wear earplugs. the noise is annoying when using in the car. it takes 30-60 mins to clean the air in a small space...and after using it a few times, it doesn't come on every time. i think the switch is faulty.it's too late to return via amazon. i contacted vapor-eze.
