The Critical Role of Air Quality in Healthcare
Healthcare facilities are meant to be places of healing, yet they are also high-risk environments for airborne infections. The presence of viruses, bacteria, and airborne contaminants poses a serious risk to both patients and healthcare workers, making air purification a critical component of infection prevention strategies.
Recent studies have shown that HEPA air cleaners can reduce exposure to airborne viruses, including simulated SARS-CoV-2 aerosols, by up to 65%. When paired with universal masking, this reduction increases to an impressive 90% [1]. This highlights the urgent need for advanced air purification systems in hospitals, clinics, and long-term care facilities.
How Airborne Contaminants Spread in Healthcare Facilities
Hospitals, medical offices, and long-term care centers often contain high concentrations of airborne pathogens due to:
🔹 Coughing and sneezing – Patients with respiratory infections release airborne droplets that can linger in the air for hours.
🔹 Insufficient ventilation – Poor air circulation allows viruses and bacteria to accumulate, increasing the risk of transmission.
🔹 High patient turnover – Frequent movement of patients and staff contributes to the continuous circulation of contaminants.
🔹 Shared spaces – Waiting rooms, exam rooms, and ICU units expose multiple individuals to potential airborne transmission.
These factors make it essential for healthcare facilities to implement robust air purification solutions that continuously remove harmful contaminants from the air.
Scientific Evidence Supporting Air Purification in Healthcare Settings
📌 HEPA Filtration Reduces Viral Transmission
A study published by the CDC (Centers for Disease Control and Prevention) found that using HEPA air cleaners in indoor settings reduced exposure to simulated SARS-CoV-2 aerosols by up to 65%. When combined with masking, the effectiveness increased to 90% [1].
📌 Medical-Grade HEPA 13 Filters Capture ≥99.997% of Viruses
Medical-grade HEPA 13 filters capture ultrafine airborne particles, including bacteria, viruses, and allergens, at an efficiency rate of ≥99.997%, making them essential for reducing airborne transmission in hospitals [2].
📌 Nanosilver and Nanocopper Filtration for Virus & Bacteria Elimination
The Castus Air Purifier enhances standard filtration by incorporating nanosilver and nanocopper technologies, which have been scientifically proven to:
