Review Text: Simple and Powerful. This is a large air purifier for larger rooms. We're using this in our Master Bedroom. The controls very are simple to operate, with a manual, auto and night modes, and a timer. The auto mode regulates the speed based on the air quality, this is displayed in a large display in the front of the unit, which has numbers and a color ring (different colors indicating air quality). There is also a night mode that runs at its lowest speed, ideal for bedside usage. Filters: It has large an thick HEPA filter, a carbon filter of the same size, and a thin mesh covering the outer filter. Replacing the filters takes seconds and no tools. The unit has a filter replacement indicator for each filter. The HEPA filter is for particulates, including allergens. The carbon filter is for reducing ambient odors. There is also a dust sensor on the side of the unit, that the manual indicates it should be cleaned every couple weeks, and oddly, has a screw cover. The unit is well constructed. The air movement is provided by a 'squirrel cage' fan (similar to most HVAC units) powered by a digital motor (These are the most precise motors, also used by the latest high-end vacuums, etc.). It also has a light sensor that turns off all the indicators, except the color ring, which is dimmed to a faint glow. It's a thoughtfully designed machine. Note that if the unit looses power it will remain off, so it won't work with smart switches, and has no remote controls.
