Product Description:
402 Series particle filter replacement Kit for the Blueair model 402 air purifier. One complete filter change. Includes one standard HepaSilent filter of polypropylene (traps particles)

Rating : - Great filter for great air cleaner.
The Model 402 Air Purifier is a great product. The sound is barely perceptable at night. The unit is slightly larger than I expected along with a large filter but that what is required to properly filter the air. The filter and unit are expensive but the construction of filter and unit are bullet proof. I expect the unit to last a life time and the filter lasts a long time too and is easy to change.
