With many of us spending a large proportion of our time in commercial spaces, whether it’s for pleasure or running a business, the last thing we need is to worry about the air we breathe. However, thanks to nearby traffic, industrial pollution, or even exposure to germs and viruses from the people we meet, we all find ourselves increasingly vulnerable to poor air quality

One of the most effective ways at improving the air quality in your commercial space is to invest in an air purifier. Those equipped with HEPA filtration are capable of capturing particles as small as 0.1 microns, which the EPA state, offer an excellent solution to eradicating airborne bacteria and viruses. 

As well as helping control bacteria and viruses, an air purifier will also keep mold, dust, and even rodents at bay. By filtering out any polluting particles that pass through the purifier, the contents of your space will also reap the benefit of cleaner air. Keeping valuable stock, equipment, and tools in tip-top condition.  

To help you in your search for the perfect commercial air purifier, we’ve put together 8 top recommendations. When purchasing an air purifier, it’s important to ensure the machine is capable of cleaning the volume of air in your space. Each machine on our list is suited to larger spaces, but look out for the CADR score and room size suitability, which tests how well an air purifier works in a given sized space.

When selecting our recommendations, we utilize Consumer Reports and analyze product reviews through Fakespot, to ensure other genuine users are happy with the performance of the purifier, so you can rest assured the purifier you choose will improve the air quality in your space.

Frequently Asked Questions

Why is air quality important in commercial spaces?

Indoor air quality is typically a significant concern to businesses, consumers, employees, and building managers as it can impact the wellbeing, comfort, productivity, and health of the building occupants. 

Poor indoor air quality in many organizations leads to decreased productivity, increased absenteeism, and potential safety risks. Employers have the responsibility to ensure a healthy and safe workplace. Air quality is critical since it provides the standards and objectives for significant airborne pollutants designed to protect the environment and human health.

Why is air quality a big concern regarding health?

The international agency for research classified outdoor air pollution and particulate matter as carcinogenic to individuals. Airborne pollutants in the air usually slip past the body defense system into our circulatory and respiratory systems damaging the lungs, brain, and heart. 

No matter your location, you can be exposed to harmful air pollutants. The effects of outdoor and indoor pollution can contribute to ill-health and many deaths every year. 

Prolonged exposure to air contaminants might lead to permanent health impacts such as decreased lung function and health conditions such as bronchitis, asthma, and cancer. Good air quality serves to save and improve our lives and minimize air quality-related conditions.

Can you use an air purifier with open windows?

It depends, as air purifiers can work well with windows open if the right environmental requirements are met. A problem that would likely arise is that more airborne pollutants will be reintroduced into the indoor air, requiring more time for the purification process. 

When a window is open, there will always be air containing outside airborne particles. It’s not recommended to open the windows if you live in a polluted area or near car exhausts or smoke. So, open your windows if you live in a clean area with minimal air pollution. Also, you need to consider the impact on your air purifier, energy costs, and your room’s indoor environment.

Which air purifier is best for you?

Air purifiers are essential in eliminating bacteria, allergens, viruses, pollen, and even odors. They greatly help in ensuring the air we breathe is cleaner, but however, not all purifiers are built the same. Therefore, for an air purifier to be great, it must be powerful enough to effectively clean your room, whether that be an office, a storeroom, or a shop floor. Nowadays, clean air is a luxury, and air purifiers have become the gotta-have-it machine in workplaces and homes. Unlike whole house systems, room air purifiers are designed to clean the air in just a single room but not the entire building. 

Air purifiers use different technologies to reduce indoor air pollutants. Although they all serve the same purpose, the models differ depending on many factors such as room coverage and price. High-end air purifiers are typically designed for extra-large rooms as they have multiple advanced features and excellent power. 

Choosing an air purifier can sometimes be challenging. The best air purifier will efficiently get rid of airborne particles and make a large difference in the air quality in your room while operating with minimal cost. First, determine the size of your room and look at what features you value most, be that Wi-Fi compatibility, remote control capability, odor-reduction, or a smart sensor. From there, you will be able to choose the unit that best fits your requirements.
