If you're looking for an air purifier for a large office, an open floor plan, or any room over 2,000 square feet, the Airmega ProX is Coway's largest model, built to purify a 4,253-square-foot room in 60 minutes with continuous coverage up to 2,126 square feet.Â
It launched as a commercial air purifier for offices, schools, and clinics, and it has since become just as common in open-concept homes, converted lofts, and finished basements that outgrow standard-size purifiers.Â
Whether the space is an open office floor or a great room, the ProX is built to handle square footage that most units cannot.
How Much Space Does The Airmega ProX Cover?
The Airmega ProX provides continuous purification for up to 2,126 square feet and can turn over the air in a 4,253-square-foot room once per hour. Its Clean Air Delivery Rate reaches 568 for smoke, 580 for dust, and 450 for pollen, among the highest ratings in the Airmega lineup.Â
For scale, 4,253 square feet is close to the size of an NBA basketball court, or roughly the workspace for 34 people at the standard office allowance of 125 square feet each.
Why Do Two Motors Move More Air?
The Airmega ProX draws unfiltered air from both sides of the unit simultaneously via a dual-motor design. Two full Max2 filter sets process the air in parallel, so a large room turns over faster than it would with a single-motor purifier of comparable size.
What Do The Max2 Filters Capture?
Each Max2 filter set pairs an activated carbon layer, which targets odors and VOCs, with a Green True HEPA filter that captures airborne particles and allergens. Together, the two filter sets remove up to 99.999% of nano-sized particles down to 0.01 microns, based on KCL chamber testing, smaller than most common allergens and dust.
How Quiet Is The Airmega ProX?
At its lowest fan speed, the Airmega ProX runs at 23 dB(A), close to the sound of rustling leaves. Turbo mode increases airflow automatically when air quality drops, then steps back down once the room clears.
What Smart Features Come Standard?

How Does the ProX Work As An Air Purifier For A Large Office?
Indoor pollutant levels are often two to five times higher than outdoor levels, according to the EPA, and anyone working in a shared office space is exposed to those levels for most of the day. Placed centrally, a single Airmega ProX can turn over the air in a 1,500-square-foot conference room, classroom, lobby, or coworking space several times an hour, making it a fit for large offices, schools, clinics, restaurants, and open retail floors.
How Does the ProX Work In Large Open Floor Plan Homes?
Open-concept homes run into the same square footage problem as a large office. A single kitchen, living, and dining space can span well past what a standard air purifier is rated to cover. The Airmega ProX handles that footprint without needing a second unit, and Eco Mode keeps it from running at full power once the room's air is already clean. It works well in great rooms, converted lofts, finished basements, and multi-level open floor plans.
How To Choose The Right Airmega For Your Space?
The Airmega ProX is built for rooms larger than 2,000 square feet or high-traffic commercial spaces. For mid-size rooms, the Airmega 300, 400, and 450 cover anywhere from around 900 to over 3,000 square feet, and the Icon and IconS bring the same particulate filtration standard to living rooms and bedrooms in a more compact design.Â
Every model uses the same filtration approach, so the right pick comes down to matching the square footage of the room it needs to cover.
Is The Airmega ProX Good For Home Use?
Yes. While it was designed first for commercial spaces, the Airmega ProX works well in any home with an open floor plan, high ceilings, or a room over 2,000 square feet, including great rooms, finished basements, and converted lofts.
Â
How Do I Know When To Replace The Filters?
The Airmega ProX has a built-in filter replacement indicator that alerts you when it's time to replace the filter, so you do not need to track a fixed schedule yourself.
Can The Airmega ProX Run All Day?
Yes. It is ENERGY STAR certified and designed for continuous operation, and Auto and Eco Modes adjust fan speed based on real-time air quality, so it is not running at full power around the clock.
Does The Airmega ProX Work In Rooms With High Ceilings?
Its coverage ratings are based on standard ceiling heights, so rooms with unusually high or vaulted ceilings may take longer to fully turn over. Central placement helps the unit circulate air more evenly in taller or irregularly shaped rooms.
Whether you're outfitting an office floor or a great room that has outgrown its current purifier, the Airmega ProX is built to keep up.Â
