The Covid-19 pandemic has drastically impacted our concerns about the air quality in commercial spaces, where we spend a significant amount of time for both personal and business purposes.

Due to factors such as proximity to traffic, industrial pollution, and the potential transmission of germs and viruses from individuals we encounter, our susceptibility to compromised air quality has increased significantly.

Acquiring a commercial grade air purifier is a highly beneficial investment to enhance the air quality within your commercial environment. Models featuring HEPA filtration have the capacity to trap particles as tiny as 0.1 microns, as recommended by the EPA, providing an effective solution for eliminating airborne bacteria and viruses.

In addition to their effectiveness in controlling bacteria and viruses, commercial HEPA air purifiers also play a vital role in preventing the presence of mold, dust, and even rodents. By effectively filtering out pollutants that pass through the purifier, cleaner air is circulated throughout the space, benefiting valuable inventory, equipment, and tools by maintaining their optimal condition.

When considering an air purifier for a workspace where you will be working alongside it, it’s essential to take into account the noise level it produces. Even a noise level of 60 dB can be too distracting for concentration-intensive tasks. Therefore, it is advisable to select units that generate minimal noise, especially if people will be working in close proximity to the purifier.

It is important to be cautious of companies that sell overpriced air purifiers and commercial air cleaners specifically targeting commercial customers. In essence, an air purifier consists of a fan and a filter. Unfortunately, there have been instances where businesses and schools have been targeted with overpriced units that make exaggerated claims but ultimately fall short of delivering the promised results.

In the majority of cases, it is advisable to choose an air purifier from a well-established brand that has been in the market for several years and has a proven track record. Look for brands that have undergone thorough third-party testing, including the ones conducted by reputable organizations like HouseFresh. This ensures that you are investing in a reliable and effective air purifier that has been rigorously evaluated and endorsed by independent evaluations.

The decision between one large air purifier or multiple small ones depends on your specific circumstances. In a large space, using a single unit can be more cost-effective in terms of filter replacement and maintenance. However, for complex layouts or areas that require more air purification than a single unit can handle, combining multiple air purifiers is beneficial. By combining their total Clean Air Delivery Rate (CADR), multiple units can provide more power and effectively clean the air in larger or multiple spaces simultaneously. Keep in mind that running multiple units will result in higher costs but offers the advantage of maintaining cleanliness in multiple areas at once.
