Commercial Purification: Large Area Air Purifier

Commercial Purification: Large Area Air Purifier

 By Justin J. Murphy

Let’s air it out—ever since the pandemic, large spaces with lots of people feel…different. Breathing in and out in a lobby, classroom, office, or medical building makes you feel…a bit on edge. We’re more aware of air. We’re more aware of each other. We’re more aware of our environments. 

The truth is, we should have access to pure clean air everywhere we go. Colds, flus, bacteria, and pollutants can cause our days, weeks, months, and lives to get difficult. But it goes far beyond a minor cold or calling in sick for a day or two—breathing clean air can lessen the possibility of disease from stroke, heart disease, and lung cancer, and can also reduce respiratory illnesses like asthma.

Large Area Air Purifier

Choosing to purify your air isn’t just about temporary convenience—it’s about longevity. What we take into our lungs each second can have a major effect on our future.

But how do you deliver clean fresh air in large spaces? How do you give people the peace of mind that comes with knowing they’re walking into a clean atmosphere that’s reducing the risk of illness associated with airborne contaminants so we can all breathe better and live more healthfully? 

We’ve put together the top 5 ways you, your business, your school, or your practice can breathe in and out without worry. 

Open the Windows

This one’s a no-brainer. If you have fresh clean air outside, let it in! Opening a window can quickly reduce the amount of harmful pollutants in an interior space by naturally pushing them out. That being said, the air outside isn’t always fresh and clean. Keep those windows closed during suboptimal air quality days and use an air purifier and/or AC to help filter out the pollutants.

Rejuvenate Your Space with Indoor Plants 

Who doesn’t love plants!? They not only uplift interior design concepts, but also remove trace levels of toxic vapors, pull in carbon dioxide, and release oxygen. They produce an array of prismatic greens and bloom deep colored flowers. In short, indoor plants not only look good, but can also make you feel good.

Air Out New Furniture and Accessories 

New furniture can make a room pop. Unfortunately, new furniture comes with a high dosage of volatile organic compounds (VOC’s), which are found in glues, paints, fabrics, and other construction materials. So, remember to air out those new mid-century loveseats before you give your interior space some love.

Reduce the Chance of Mold

One minor roof leak can lead to major problems. Mold is responsible for an array of respiratory health issues that can wreak havoc on your immune system, lungs, and finances. A general rule of thumb is to always keep your indoor spaces at 50% humidity or below. If you live or work in an exceptionally damp region, a dehumidifier can help remove moisture in the air and reduce mold.

Get an Air Purifier That Does It All

While opening windows and airing out furnishings are great for keeping air clean naturally, nothing beats a powerful, advanced large area air purification system or commercial air purifier like the Airmega ProX. Not every air purifier works for large spaces. The ProX purifies 2,126 ft² rooms in 30 mins and 4,253 ft² rooms in 60 mins. That means no matter how large your space is, the ProX has you covered. Another great large area option, the Coway Airmega 400S smart air purifier can purify over 1500 square feet of air, and remove over 99.98%³ of the SARS-CoV-2 virus and more than 99.999%¹ of all airborne contaminants down to 0.01 microns, exceeding the EPA’s recommendation to ensure you’re breathing easy in large spaces. 

But it doesn’t just stop at the lobby, classroom, or movie theater. Purifying the air in all interior spaces reduces the transmission of viruses and removes pollutants so you can build a healthful environment throughout your live and/or workspace. After all, what’s the point of cleaning the air in the lobby if you aren’t breathing clean air in the office? In order to ensure you’re inhaling clean air throughout the day (we spend 90% of our time indoors), focus on a combination of larger and small air purification solutions that work wherever you’re working.

Commercial Air Purification 

As a global community, we have a responsibility to look out for one another. And with advanced technology and access to an abundance of information and research, it’s never been easier to create healthful indoor environments that benefit everyone. If we work together to eliminate indoor and outdoor pollutants, we can build a more health-centric, eco-friendly community whose practices will positively enhance our lifestyle for generations to come.


1Coway air purifiers have been proven to trap dust, pollen, dander, viruses and bacteria in the air based on KCL (Korea Conformity Laboratories) testing.They have been tested in a 30㎥ size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2022 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum airflow speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

4The concentration of ammonia, acetaldehyde and acetic acid were proven to be removed within 30 minutes by FCG Research Institute, Inc. Human Life Science Lab. It is not a demonstration result in the actual use space. Not all odors and gases may be supported. → Tested with Coway Airmega 150, 160, AP-1512HH, AP-1512HHS, 400, 400S

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
