Air Cleaning and Purification Technologies are Suited to Healthcare, Pharmaceutical, Education, and Industrial Application

Now more than ever before, clean, pure air is critical for any commercial indoor space. However, air purity has a range of definitions when it comes to environmental systems. For some facilities, removing particulates and dust is critical. For others, the focus is on viral and bacterial microbes. That’s why today’s air purification products and processes address a wide variety of air quality concerns.

Hospitals and healthcare facilities are especially concerned with airborne pathogens. In these situations, air purification systems must prevent the matter from circulating between rooms and common areas in the airstream. In addition, pharmaceutical sites, especially laboratories and manufacturing, must remove particulates and gases from the air, protecting the products from contamination while also ensuring employee health.

Removing particulates, allergens, and other contaminants from the airstream has also become a primary concern of educational and educational research facilities. Schools and universities need air purification systems that can neutralize dangerous pathogens that can be present in a densely occupied space.

To maintain manufacturing or research integrity, many cleanrooms must reduce particulates even at the microbial level. Therefore, each application must meet address specific conditions to meet a range of requirements.
