Bests & Worsts Reviews from Amazon

I haven't written many reviews for Amazon products, but I have been an Amazon customer ...since there was an Amazon. I used to write reviews for many years with the now defunct Epinions.com. I just had to pen a quick review of this air cleaner as I found it to be well designed and well built. Pros: Well built with a fairly heavy plastic case, this case is easy to care for and use. It has four speed settings from low to turbo. On its lowest setting it is almost silent. Set to turbo it moves as much air as the old Honeywell 17000s unit this replaced. Te front case opens easily and has a magnetic button which turns to unit off to service the filer. I vacuum the pre-filter every other week and this easy of servicing really makes this a simple task. The additional UV-C feature is cool, but I'm not sure of its value. If there were any nasty pathogens affected by the UV-C light, its nice to know they might be neutralized by this feature. This seems to clean the air at least as will as the old Honeywell 17000s. (Honeywell was famous for not selling filters for its air cleaners and when they did, they came at high prices. Finally, our second 17000s died, so moving to a new manufacturer was easy due to Honeywell's lack luster product service). Cons: The negative ion feature is questionable as research appears to indicate that negative ion generation is not beneficial, and possible detrimental to human lung tissue. Thankfully, this feature can be turned off. For such a well designed machine, I wonder why the included such a questionable feature. There IS a rather strong plastic smell during the first few days of operation. If one is particularly sensitive to this, try operating it near an open window for a day or two. The smell does go away...we are rather fussy about that. Overall: Well designed, quiet on the lower settings and capable of moving more air when needed, this air purifier checks many boxes. It's easy to service and performs well. I can recommend this unit.
