Bests & Worsts Reviews from Amazon

This is a great air purifier for the price. The build quality on the machine is above average compared to other similarly priced air purifiers on the market, and it has an attractive two tone silver/white finish that blends in with the environment. The LED interface looks great and has a slightly high-tech look to it. There is a SLEEP mode that dims the LEDs in a dark room. The purifier draws air from the front and dispels the cleaned air from the top of the unit. It is a 3-Stage cleaning unit (Carbon Filter --> HEPA Filter --> Plasmawave Ionizer), and the air dispelled from the purifier smells CLEAN. Information on Ozone: Some air purifiers create Ozone during their ionization process. Since this uses a "plasma" technology, the Ozone creation is minimal. This particular model only creates 3 ppb when Plasmawave is turned on. This is far below the FDA recommended 50 ppb limit. The box advertises a "NO OZONE" logo with information on Ozone production. There is no distinct Ozone smell that some other purifiers create. CADR Specs: 350 sqr/ft room Smoke: 235 Dust: 248 Pollen: 251 When the purifier is set to Auto mode, it uses the air sensor to change the speed of the fan when needed. It never goes to Turbo mode when set to Auto, so the High setting is the loudest it will get. Most of the time in Auto mode, the fan is set to Low. On Low you can not hear the fan unless you are close to it and the Plasmawave is set to OFF. On Medium the fan is slightly audible and the Plasmawave is turned on. Some complain of a weird almost "clicking" noise when the fan is on Medium with Plasmawave on, and this is true. It is VERY quiet (at least on my machine) and I only hear it if I am right next to the purifier and actively listening for it. This might be a problem for those who have this is their bedroom, but you can turn off the Plasmawave with the provided remote. On High, the fan is clearly audible and the Plasmawave is turned on. You cannot hear the Plasmawave noise when the fan is set to High. Turbo is very loud and Plasmawave is turned on, but it moves a lot of air in this mode and is really useful for clearing out a room quickly. Even though it is loud it isn't that obnoxious. The air sensor that is installed on this device is extremely sensitive, holding up anything that gives off an odor automatically triggers the purifier to increased the fan speed depending on how bad the odor is. Nail Polish, food odors, laundry have all set the sensor off even if the smells are faint. FYI: The sensor is an Odor sensor, not a Particle sensor, so it does not detect dust or pet hair. The remote is a little bulky but is very handy. You can manually turn the fan from Low --> Turbo, turn Plasmawave Off/On, turn the purifier Off/On, and set up the different modes. You cannot activate the Auto mode with the remote, but turning off the purifier off then on again automatically turns the Auto feature on. The remote sits in a designated holder on the top of the purifier. To wash the HEPA filter, hold it under a stream of room temperature water at a 45 degree angle and thoroughly rinse it. Then let it air dry for 12-24 hours or until dry to the touch. Make sure to grasp the edge of the filter and not the inner "flaps" because you can damage/warp them when they are wet. You can also vacuum the HEPA filter occasionally, but I am not sure if it will increase its lifespan. Some things I did not like about the purifier were the lack of handles on the sides. It isn't a very heavy unit but handles would make moving it from room to room much easier. Also, the lack of an Auto button on the remote is slightly annoying. The carbon filters are thin compared to other units and are a little expensive. The lack of a particle sensor is also a con.
