The Blueair Classic 405 air purifier is an excellent choice for those looking to clean a room or office up to 430 square feet. We like that you can purchase the Odor Smokestop air filters for chemicals and odors. We would encourage the purchase of the Odor Smokestop filters for all-around filtration to provide the optimum clean indoor environment. The HEPASilent particle filters are good for particle filtration, but do not have any carbon so they will not remove any odors or chemicals from the air. Ideal for clean air in a quiet environment.
