The product is modular and portable in design and can be suitable for different requirements such as institutional, hospitals and home/ individual quarantine. The envelope is reusable as it is antibacterial-antifungal and can be sanitized.

Each envelope is capable of housing one set of bed, table and chair along with some walking space. The width of the envelope can be adjusted as per the availability of space. Envelope is opaque up to 3 ft from bottom to maintain privacy of the patient.

The entire envelope is maintained at a low pressure (suction) with adjustable flow rate to restrain spread of virus/ infection inside the hall/ ICU. Each envelope is connected to the main duct equipped with UV light and filter circuit of Pre, fine and HEPA filter (recommended for medical application) and suction blower.

The cross flow of air from top of the envelope towards the main duct is regulated (with a flap valve) as per the comfort conditions of the patient. The virus / contaminants are continuously sucked through the duct and accumulated at the filters which are projected with UV light. The suction blower throws the filtered and contamination free air to the outside environment.
