I have been wanting an air purifier for a while, and I am definitely impressed with this one. It is a good size and covers the space in my bedroom easily. It has multiple settings, such as three different fan speeds, hourly timers, and a night setting. The fan settings also help with the noise level. But overall, it isn’t too loud and I am able to sleep fine with it on. It’s simple to use. Take the plastic off the HEPA filter and it is ready to go, right out of the box! After using for the last week or two, I feel like the air quality has improved and I don’t find myself waking up as stuffed up or sneezing as much. I definitely recommend!
