How Air Filtration Works

Optimal air filtration and ventilation are an essential part of our long-term commitment to a safe and healthy workplace environment.

We flush and replace the air in our workplaces at regular intervals, both during occupancy and after hours, on average every 60 minutes.

In our restrooms, air is replaced approximately 10 times every hour.

Stale air is flushed from the workspace up into the ceiling by the air handler.

During the air exchange, air is both exhausted out of the building and mixed with filtered, outside air that passes through high-efficiency MERV-rated air filters.

Air Handler System

The mechanical systems in all our workplaces use high-efficiency MERV-rated air filters, with more than 75% using MERV 13 or higher, effectively trapping airborne particulates.

Filters are disinfected as part of the replacement process and coils and unit interiors are sanitized to maximize air quality.

How Particulates Disperse

This fresh, filtered air is delivered to suites in the building via the air supply ducts, maximizing fresh air exchange.

Here’s a scenario where someone coughs or sneezes.

Thanks to increased air movement, particles begin to disperse immediately, reducing concentration and risk of infection.

Customer Suite Particulates

Within 30 minutes, 90% of particles disperse.

Here’s how they flow back to the HVAC system and through the high-efficiency MERV filter.

Independent, third-party testing confirmed our HVAC system does not exchange particulates between offices or customer suites before they are filtered out of the system.

Our high-efficiency, MERV-rated air filters trap airborne particulates, supporting optimal air quality.

Elevator Airflow

Elevator air is exchanged every minute while the elevator is traveling, in addition to the influx of fresh air that occurs whenever the doors open. With a typical ride lasting under 30 seconds, our customers enjoy fresh air on every ride.
