What is the new Indoor Air Quality Procedure?
The IAQP is an alternative to the traditional Ventilation Rate Procedure (VRP). Instead of relying solely on outdoor air intake, IAQP combines air purification and filtration to reduce required ventilation by up to 80%. This means cleaner air and significant energy savings. It also ensures compliance with ASHRAE Standard 62.1-2022 and its Table 6-5 limits for chemical compounds.
What is ASHRAE Standard 241?
In late 2022, the White House contacted ASHRAE to help prepare for the upcoming expiration of Title 42 and the end of the COVID public health emergency. The government appointed ASHRAE with the responsibility of creating a comprehensive guide to operate buildings in a way that will help prevent the spread of airborne infectious illnesses. Thus, the creation of Standard 241: Control of Infectious Aerosols.

Why Certified HEPA Filters Matter—And What You Should Ask Before You Buy
HEPA filtration is more than a buzzword—it’s a benchmark for critical environments that can’t afford compromised air. Used across industries where air purity is non-negotiable, certified HEPA (High-Efficiency Particulate Air) filters are the proven choice for removing harmful particulate matter that threatens both human health and sensitive processes. Industries That Rely on True HEPA HEPA, the gold standard of filtration, is widely used in sectors that demand the cleanest air possible, such as: Semiconductor manufacturing Nuclear containment Biotech and pharmaceutical labs Microchip and electronics production Hospital operating rooms and isolation wards Aerospace cleanrooms High-containment BSL laboratories Defense and military applications Food and beverage clean processing If these industries trust HEPA to protect critical operations and human health, it raises an important question: why wouldn’t your facility? What Makes a HEPA Filter Legit? Not all “HEPA” claims are created equal. True, certified HEPA filters must meet strict performance standards—specifically capturing 99.97% of particles at 0.3 microns or better (some certified filters even test to 99.99%). But how do you verify that the filter in your system is performing as it should? Here’s what you should ask any air purifier manufacturer or vendor: Is the filter certified to IEST-RP-CC001? Do your filters meet or exceed ASHRAE Standard 52.2 testing? Do you have ISO 29463 or EN 1822 classification data? Can you provide independent lab results or certification documentation? What DOE (Department of Energy) or cleanroom-grade standards do you meet? Without answers to these, you may be buying a label—not a real solution. The Danger of PM2.5: Invisible, But Potent One of the biggest threats to indoor air quality today is fine particulate matter smaller than 2.5 microns (PM2.5). These particles can penetrate deep into the lungs, enter the bloodstream, and contribute to long-term health problems such as respiratory diseases, cardiovascular issues, cognitive decline, and even cancer. Because they’re invisible to the naked eye, PM2.5 often goes undetected without proper filtration in place and can be found around you in: Vehicle exhaust (diesel and gasoline engines) Industrial emissions (factories, power plants, refineries) Pollen Combustion byproducts (from burning wood, coal, oil, or natural gas) Cigarette smoke and secondhand smoke Wildfire smoke Cooking fumes (especially frying, grilling, and burning oils) Construction dust (fine dust from concrete, drywall, etc.) Agricultural burning and field dust Mold spores Biological fragments (skin flakes, bacteria, organic debris) Brake and tire wear particles (from roadways and traffic) Indoor dust (resuspended fine particles from surfaces or carpets) These microscopic pollutants are all around us—indoors and out—and their ability to bypass the body’s natural defenses makes them especially dangerous. Certified HEPA filters actively capture PM2.5 and even smaller particles with verified efficiency, unlike standard filters, making them one of the most effective tools for protecting indoor air quality. In environments where health, safety, and compliance matter, HEPA isn’t just a filter; it’s peace of mind. HEPA and IAQP The Indoor Air Quality Procedure (IAQP) provides building designers with flexibility to reduce outdoor air ventilation by demonstrating control of indoor contaminants. However, success depends on the effectiveness of the filtration system. While HEPA filtration isn’t explicitly required under IAQP, it’s hard to justify using anything less when PM2.5, one of the most dangerous and pervasive airborne pollutants, is listed in ASHRAE’s Table 6-5. HEPA filters, proven to capture 99.97% or more of particles down to 0.3 microns, offer unmatched protection against PM2.5. Beyond health, better filtration means you can confidently lower outdoor air intake, which reduces HVAC equipment sizing, capital costs, and long-term energy consumption. In short, using HEPA with IAQP isn’t just a win for indoor air quality, it’s a strategic move for cutting costs and future-proofing your building.

Is IAQP Replacing DCV for Energy-Efficient Ventilation?
As building codes evolve and indoor air quality (IAQ) becomes a top priority, many design teams are rethinking their approach to energy-efficient ventilation. For years, Demand Control Ventilation (DCV) has been the standard method for reducing energy consumption in commercial facilities by adjusting ventilation rates based on occupancy levels. However, an increasing number of engineers and owners are looking to the Indoor Air Quality Procedure (IAQP), a performance-based alternative that ASHRAE Standard 62.1-2022 defines and outlines as a smarter, more flexible solution. The reason? IAQP doesn’t just save energy; it can significantly reduce HVAC system design size, improve indoor air quality, and simplify long-term operation and maintenance. Limitations of Demand Control Ventilation While DCV can reduce outdoor air intake during periods of low occupancy with CO₂ monitoring, it presents several engineering and operational drawbacks: No reduction in equipment sizing: Despite reduced outdoor airflows during operation, engineers must still size systems according to the Ventilation Rate Procedure (VRP) for full design occupancy. This results in no capital cost savings on air handling units (AHUs), ductwork, cooling capacity, etc. Sensor reliability challenges: DCV depends on CO₂ sensors that are prone to drift, require frequent calibration, and can be difficult to manage across distributed systems. Inaccurate readings can lead to over-ventilation (wasting energy) or under-ventilation (risking occupant health). Increased compliance burden: ASHRAE has introduced stricter sensor calibration and accuracy requirements in recent revisions to Standard 62.1, increasing both the initial and ongoing cost and complexity for facility managers and OEMs. Limited pollutant control: DCV is occupancy-based and does not address airborne contaminants such as VOCs, PM2.5, ozone, or formaldehyde—many of which are known carcinogens or respiratory hazards. A space can meet CO₂ targets while still failing to ensure healthy indoor air. IAQP: A Smarter Performance-Based Alternative Unlike DCV, IAQP is a performance-based design method that enables reduced outdoor air rates if contaminant levels can be controlled using validated technologies such as high-efficiency filtration and air cleaning systems. This approach allows engineers to balance energy efficiency with real indoor air quality improvements. Key advantages include: Smaller HVAC systems and reduced first costs: By designing for lower ventilation rates, IAQP often requires smaller AHUs, DOAS, reduced duct runs, fewer or smaller ERVs, and more, significantly cutting first costs on new construction and depending on the air cleaning equipment, often times seeing net savings on new construction. Targeted removal of harmful pollutants: IAQP outlines harmful pollutants in ASHRAE Table 6-5, many of which are carcinogens or linked to chronic disease. By actively mitigating these contaminants with proven removal efficiency tested air cleaners, building owners gain increased occupant health and safety and a defensible strategy to reduce liability related to indoor air complaints, wellness claims, or future regulatory action. Verified performance through testing: Technicians measure and verify indoor air quality through contaminant testing, using real performance data rather than assumptions based on occupancy alone. Post-implementation Verification Testing takes out the guesswork of IAQP equipment performance. AirBox + IAQP: Integrated Solutions for Compliance and Performance AirBox delivers a turnkey solution for implementing IAQP effectively by combining engineering and design support, compliant air purification systems, comprehensive IAQ Verification Testing, compliance documents, and advanced system control with the AirBox Advanced Operating System (AOS).

Boosting Lab Air Quality: How Air Purifiers Can Increase Air Changes per Hour (ACH)
Maintaining optimal air quality is paramount in laboratory environments. Contaminants like particulate matter, volatile organic compounds (VOCs), and pathogens can compromise research accuracy, equipment integrity, and, most importantly, the health and safety of lab personnel. While HVAC systems are a crucial component of lab ventilation, sometimes they are insufficient to achieve the required Air Changes per Hour (ACH) necessary for specific applications or to address localized air quality concerns. This is where introducing compliant air purification can make a significant difference. Understanding the Importance of Air Changes per Hour Air changes per hour refers to the number of times the total volume of air in a room is replaced with fresh, filtered air within one hour. Consequently, higher ACH generally translates to improved indoor air quality and reduced concentration of airborne contaminants. The recommended ACH varies depending on the type of laboratory and the specific hazards present. Factors influencing the required ACH include: Type of Research: Experiments involving infectious agents, hazardous chemicals, or sensitive materials require higher ACH. Equipment Used: Equipment that generates fumes, particles, or heat can necessitate increased ventilation. Occupancy Levels: Higher occupancy rates increase bioeffluents and airborne pathogens, all of which affect ventilation demand. Regulatory Guidelines: Organizations such as ASHRAE provide guidance on ventilation requirements for specific laboratory settings. Limitations of Existing HVAC Systems While HVAC systems play a critical role in lab ventilation, they may face limitations in achieving the desired ACH: System Capacity: Older or undersized HVAC systems may lack the capacity to provide adequate airflow for the entire lab. Distribution Issues: Air distribution problems can lead to uneven ventilation, with some areas receiving insufficient airflow. Cost of Upgrades: Upgrading the existing HVAC system can be a significant investment. Disruptions During Renovation: Major HVAC upgrades often require lab downtime and potential disruptions to research activities. How AirBox Can Enhance ACH and Indoor Air Quality AirBox High-Volume Purifiers (HVPs) offer a flexible and cost-effective solution to supplement existing HVAC systems and improve indoor air quality in labs. Here's how they contribute: Increased Localized ACH: AirBox HVPs can be strategically placed in areas where higher ACH is required, such as around fume hoods, biosafety cabinets, or in areas with high concentrations of particulate matter. Effective Filtration: Equipped with Certified HEPA and Advanced Molecular Adsorbent filtration, AirBox HVPs capture 99.99% of airborne particles, as well as Volatile Organic Compounds (VOCs) and other harmful chemical contaminants. Minimized Maintenance: By utilizing the AirBox Advanced Operating System (AOS), facilities can integrate with their Building Management Systems (BMS) to manage, adjust, schedule, and monitor their HVPs. Additionally, the AirBox AOS allows live IAQ and filter-life tracking with integrated sensors on board. Emergency Response: AirBox HVPs can quickly address indoor air quality risk from contamination events like viral outbreaks, wildfire smoke, and more through an easy switch to ASHRAE Standard 241-2023's Infection Risk Management Mode (IRMM) to increase clean airflow. Reduced Strain on HVAC: By filtering air locally, AirBox purifiers alleviate some of the burden on the HVAC system, potentially extending its lifespan. Conclusion: A Smarter Path to Safer, More Compliant Labs In laboratory environments where precision, safety, and regulatory compliance are non-negotiable, maintaining high indoor air quality is critical. Consequently, achieving the appropriate Air Changes per Hour (ACH) is key. While traditional HVAC systems form the backbone of lab ventilation, they often fall short when it comes to localized needs, rapid response to contaminants, or cost-effective scalability.
