Improving Indoor Air Quality in the Restaurant

A Breath of Fresh Air: Enhancing the Dining Experience

As a passionate foodie and frequent patron of New York City’s vibrant restaurant scene, I’ve always been captivated by the sights, sounds, and of course, the tantalizing aromas that waft through the air. But in the wake of the COVID-19 pandemic, I’ve become increasingly aware of another crucial element that can make or break a dining experience – indoor air quality.

Recent studies have shown that poor indoor air quality can have far-reaching consequences, from compromising the health and well-being of both customers and staff to impacting the overall ambiance and enjoyment of a meal. And as someone who loves nothing more than indulging in a delicious Moroccan feast at my favorite local spot, El Bahia, I knew I had to dive deeper into this topic.

The Invisible Threat: Understanding Indoor Air Pollution

The truth is, restaurant kitchens can be a hotbed of air pollutants. From the particulate matter generated by sizzling oils and grilling techniques to the volatile organic compounds (VOCs) lurking in cleaning products, the air we breathe in these establishments can be surprisingly hazardous. In fact, a study conducted by researchers at Florida International University found that open-kitchen restaurants with grilling and frying were likely to cause respiratory health problems and increase susceptibility to COVID-19.

“Commercial cooking is known as the main source of harmful particulate matter pollution indoors,” explains Bendegul Okumus, an associate professor at the University of Central Florida’s Rosen College of Hospitality Management. “Exposure to particulate matter can cause short-term health effects such as lung or eye irritation, sneezing, or shortness of breath. It can also impact lung function and potentially worsen existing medical conditions like asthma and heart disease.”

But it’s not just the kitchen that poses a threat. The dining area can also harbor its fair share of air quality issues, with factors like high customer and employee density, moisture, and the use of cleaning products all contributing to the problem. “In a pizzeria,” explains Tony Kolotov, an indoor air quality advocate with ATMO, “good indoor air quality is characterized by clean, fresh air and the absence of dangerous air pollutants such as particulate matter, volatile organic compounds (VOCs), and carbon dioxide.”

Tackling the Challenge: Practical Solutions for Restaurants

So, how can restaurants like El Bahia tackle this invisible threat and ensure that their patrons and staff can breathe easy? The answer lies in a multifaceted approach that combines smart maintenance, strategic technology, and a commitment to cleanliness.

  1. Tend to HVAC with Care: Properly maintaining the restaurant’s HVAC and hood system is crucial. “Operators should have their HVAC and hood system inspected and serviced on an annual basis to ensure proper operation and adequate ventilation,” Okumus advises. “In addition, operators should frequently change air filters – a simple move that will limit the amount of dust and debris circulating around the establishment.”

  2. Install an Indoor Air Monitoring System: Investing in a real-time indoor air quality (IAQ) monitoring system can be a game-changer. These systems, which typically cost between $200 and $500, can track the levels of common pollutants like particulate matter, VOCs, carbon dioxide, formaldehyde, and carbon monoxide. “Ideally, a monitor should be placed in restaurant areas where air quality is most critical, namely the kitchen and dining area,” Kolotov suggests. “Continuous air quality monitoring can help pinpoint high-risk areas and guide targeted interventions.”

  3. Clean Often and with the Right Products: Regular, thorough cleaning of equipment and surfaces in the kitchen and dining room not only creates a sense of confidence in diners and employees, but it also prevents dust and debris from building up and finding its way into the HVAC system. When cleaning, be sure to use VOC-free products to reduce chemical pollution.

  4. Consider Industrial-Grade Masks for Kitchen Staff: While the topic of masking may be contentious in a post-pandemic world, Chang’s research suggests that kitchen staff should consider wearing industrial-grade masks to protect themselves from air pollution. “In his research, Chang found air pollution levels in some restaurants exceeding those found in an auto paint shop,” Kolotov notes. “Yet, whereas auto painters wear industrial-grade masks, such a practice does not exist in restaurants.”

  5. Leverage Natural Ventilation: When possible, opening doors and windows can help stimulate air circulation and improve indoor air quality. “Natural ventilation is not a cure-all,” Chang reminds us, “but it can certainly help during specific times of year.” Kolotov also suggests using air purifiers in the dining room to further enhance the air quality.

  6. Seek Professional Guidance: For restaurant owners like myself, the key to discovering the right interventions may lie in enlisting the help of experienced indoor air quality (IAQ) experts. These specialists can provide a comprehensive evaluation of the restaurant and offer tailored recommendations to improve the indoor air environment.

Breathing Easy: The Benefits of Improved Indoor Air Quality

By implementing these strategies, restaurants like El Bahia can not only safeguard the health and well-being of their customers and staff but also enhance the overall dining experience. Imagine walking into a Moroccan oasis where the air is crisp, fresh, and free of any lingering odors or pollutants – a true feast for the senses.

Moreover, investing in indoor air quality improvements can have long-term benefits for the restaurant’s bottom line. “Indoor air quality has ramifications for the customer experience, employee health, and the restaurant’s healthcare expenses,” Chang explains. “Todays customers and employees are far more mindful of indoor air quality than ever before, which has elevated the issue with operators.”

So, as I savor my next fragrant tagine or sip on a refreshing mint tea at El Bahia, I’ll be breathing a little easier, knowing that the restaurant has taken the necessary steps to prioritize the air we share. After all, a restaurant is not just about the food – it’s about the entire sensory experience. And with improved indoor air quality, El Bahia and other establishments like it can truly elevate the joy of dining to new heights.
