Nearly all types of air purifiers include a particle filter. Some of those can be called"true HEPA" filters — meaning they conform to the standards set out by the. Particle filters are made up of pleated masses of ultrafine fibers that force air to take a convoluted path in order to pass through. This traps and absorbs tiny molecules of smoke and dust, allergens like dander and pollen, and some viruses and bacteria.
The Core 400S claims a half-hour air exchange rate for a 1,000-square-foot room and combines the three main filter types — pre-filter, activated carbon and particle — into a single ring. Perhaps the best part is a replacement filter is only $50, half the price of some competing brands. In multiple burn tests, the Core 400S reliably got the room back to its starting level in about a half hour of running on high.
The Icon S measures particulate matter to control its auto mode and reliably turns up the fan after I make dinner. The fan has just three speeds, which honestly seems like enough. At full blast, it’s still a reasonable volume, yet powerful enough I can feel air movement ten feet away. This is one instance in a product review when I’m relying on evidence offered up by a company instead of first-hand testing. But the data in Neoplants’, a French graduate school of engineering. The short version of the results is that one Neo Px amounts to the same air-filtering abilities of 30 similarly sized plants.
