Cleaner air you can trust—True HEPA filtration, PlasmaWave technology, and smart air quality sensing at a fair price.
Cleaner air you can trust—True HEPA filtration, PlasmaWave technology, and smart air quality sensing at a fair price.
Air enters from all sides, so you can set the A231 near a corner or between furniture without blocking its path and still get even circulation across the whole room.
The H13 True HEPA stage is the workhorse, trapping pollen, mold spores and pet dander down to fine particulate, which is the number that matters most for allergy sufferers.
Activated carbon sits ahead of the HEPA media and absorbs odor-causing compounds, so cooking smells and household VOCs are reduced instead of simply recirculated.
PlasmaWave creates a mild ionization field designed to break down pollutants while producing far less ozone than conventional ion generators, and you can switch it off.
The built-in sensor reads the room and shifts fan speed on its own, so the unit speeds up when cooking smoke or pollen settles in and eases back down once the air clears.
At its slowest setting the A231 runs near 25 dB, and Sleep Mode dims the activity so light sleepers can keep it running all night without noticing a hum in the room.
The fine mesh pre-filter and True HEPA stage trap the particles that settle on shelves and floors, which pet owners and dusty households tend to notice within weeks.
An activated carbon layer works on cooking smells, pet odors and VOCs before air circulates back into the room, so the space smells cleaner instead of merely blown over.
The LED indicator shifts color as conditions move, giving you a quick read on whether the room needs attention without opening an app or checking a filter meter.
At 6.75 pounds with a 9.5-inch footprint, the A231 slides from a bedroom nightstand to a home office and keeps covering spaces up to 246 square feet.
Run it overnight near the bed to keep pollen and dust levels low while you sleep; at 25 dB on the lowest speed it stays quiet enough that most sleepers forget it is on.
Placed near a litter area or a favorite pet bed, the pre-filter catches hair while carbon works on smell, so the room reads cleaner between your deep cleans.
In a smaller space, smoke and cooking smells travel fast. The carbon stage and auto mode respond when indoor air quality dips, without you needing to adjust anything.
A desk-side unit keeps air circulating through the workday, cutting the dust buildup that collects on a screen and keyboard whenever the windows stay closed.
Switch it on before visitors arrive to freshen a room that has been closed up, then rely on quiet operation to keep it unobtrusive during an overnight stay.
Compact at 9.5 inches wide and easy to move at 6.75 pounds, it fits a child's room without dominating the space and runs quietly enough for nap time.
