The requirement for compliant air quality in critical healthcare environments is non-negotiable. Whether managing patient infectious diseases in a hospital, protecting immunocompromised individuals in a clinic, or ensuring sterility in a specialized laboratory, maintaining precise air changes per hour (ACH) and high-efficiency particulate air (HEPA) filtration is paramount.

For organizations needing a permanent, out-of-the-way solution for infection control ventilation, the HEPA-CARE® Ceiling-Mounted Air Purification Systems offer the industry standard. Specifically, the HC800CD and HC500CD models provide the reliable, certified performance necessary to create and maintain CDC/CSA-compliant negative pressure isolation rooms.

Choosing between the HEPA-CARE HC800CD and the HC500CD, however, requires careful evaluation of your facility’s specific architectural, capacity, and operational needs. This comprehensive comparison will guide facility managers, engineers, and healthcare administrators in selecting the optimal ceiling-mounted HEPA air purification system to ensure patient safety and regulatory adherence.

The Critical Role of Ceiling-Mounted HEPA

Filtration in Infection Control

Traditional portable air scrubbers are effective but consume valuable floor space, pose tripping hazards, and can be cumbersome to maneuver. Ceiling-mounted HEPA air purification systems like the HEPA-CARE CD series solve these issues by utilizing existing drop-ceiling infrastructure.

By installing the filtration unit completely above the ceiling grid, these systems offer a permanent, hands-off solution for creating controlled air environments. They are dual-purpose tools, primarily used for:

1. Negative Pressure Isolation: Drawing air out of a room and exhausting it outdoors (or into a return system), creating lower pressure inside to prevent airborne contaminants from escaping into corridors. This is essential for infectious disease management.

2. Continuous Recirculating Air Purification: When not in negative pressure mode, the unit filters the room air internally, significantly lowering the overall microbial and particulate count, improving indoor air quality for high-risk patients.

Both the HC800CD and HC500CD utilize pharmaceutical-grade H14 HEPA filters, certified to capture a minimum of 99.995% of airborne particles 0.3 microns in size. This includes critical pathogens, spores, and microscopic infectious aerosols. The key to selection lies in the volume of air they can process—their capacity, measured in Cubic Feet per Minute (CFM).

Deep Dive: Introducing the HEPA-CARE

HC800CD System

The HC800CD is the powerhouse of the ceiling-mounted HEPA-CARE lineup, engineered for maximum capacity and demanding environments.

HC500CD System

The HC500CD model is designed for flexibility and efficiency, offering exceptional performance in smaller, more numerous critical spaces. It delivers the same certified HEPA filtration quality but in a more compact package.

Efficiency, Compactness, and Ideal Use Cases

The HC500CD uses a single, highly efficient motorized impeller, providing excellent airflow suitable for the majority of standard isolation room requirements. It maintains the same H14 HEPA filtration standards as its larger counterpart.

• Peak Capacity: 200 CFM up to 550 CFM.

• Isolation Room Performance: The HC500CD is capable of maintaining the crucial 12+ ACH threshold in standard isolation areas ranging from 2,500 to 3,000 cubic feet (approximately 15’ x 16’ to 15’ x 20’ with a 10-foot ceiling).

This balance of size and performance makes the HC500CD an excellent solution for:

• Standard Single-Patient Isolation Rooms: The most common application in hospitals, clinics, and long-term care facilities.

• Small Procedure Rooms and Labs: Areas requiring dedicated localized air quality control without excessive power.

• Outpatient and Emergency Department Clinics: When temporary or flexible negative pressure capabilities are needed immediately.

Installation Footprint

A primary advantage of the HC500CD is its highly compact size. The filtration module is designed to fit seamlessly into a standard 2 ft. x 2 ft. drop ceiling grid, requiring less space overhead and providing a solution when ceiling infrastructure is tighter or compartmentalized.

Choosing the Right Capacity: ACH

Calculation and Compliance

The decision between the HC800CD and HC500CD ultimately hinges on your facility’s requirement for Air Changes Per Hour (ACH). Healthcare standards, such as those from the CDC, mandate that an isolation room must achieve a minimum of 12 ACH to ensure rapid removal of airborne infectious particles.

To determine which unit you need, calculate the room’s volume:

In this case, only the HC800CD (max 850 CFM) is guaranteed to meet the 12 ACH requirement reliably, especially as filters load up and static pressure increases. The HC500CD would be insufficient for this large isolation room.

By calculating your exact CFM needs based on the largest or most critical rooms requiring negative pressure room air scrubbers, you can accurately match your requirement to the powerful capabilities of the HEPA-CARE CD series. Investing in the appropriate model ensures your facility maintains regulatory compliance while providing the highest level of hospital air filtration and safety for patients and staff.
