Applications

People spend most of their time indoors, except when they are in transit or participating in outdoor activities. Not surprisingly, therefore, a study by the United States Environmental Protection Agency (EPA) found that Americans, for example, spend 90% of their time indoors. Studies also show that people’s health is directly related to the quality of indoor environments, especially when the indoor air is polluted or contaminated. For these reasons, it is essential to ensure that indoor environments are safe and comfortable, including the breathing air.*

Workers, for example, are exposed not only to air pollutants carried from the external environment, but also to specific pollutants generated by production processes and their work activities. The public, in general, may also be subject to health risks when they remain inside private or public buildings where indoor air quality is not satisfactory. Health care environments are those where traditionally most concern about contamination has occurred due to the potential presence of infectious agents in the air. Even in places that have central air-conditioning systems, the indoor air quality may not be adequate and turn into a “Sick Building” as many people already know.

Purefeel has a solution for all different situations.
From production, pre-production and quality control areas in general industries and clean production environments, to administrative and support Areas, Laboratories, Health Care, Commercial and Public Buildings.

General Industries

Demands to improve working environments in both production and pre-production, control, maintenance, supervision and testing areas are continually growing due to increasingly strict regulations and to technological and management development of companies. Indoor air quality is a crucial aspect of achieving safe, healthy and productive work environments. Infectious biological agents are also a considerable risk of contamination in more densely occupied environments. Often located in closed environments or with poor ventilation, these areas can greatly benefit from Purefeel’s UPR air purification and recirculation units and/or UPO Deodorization.

Production Environments

In pharmaceutical, food and other industries with special hygiene requirements, there are a multitude of environments that, even outside the controlled areas commonly called “clean rooms”, require superior and controlled air quality. Receiving, weighing, pre-mixing, control and process supervising areas are some of them. Infectious biological agents are also a considerable risk of contamination in more densely occupied environments. Often located in closed environments or with poor ventilation, these areas can greatly benefit from Purefeel’s UPR air purification and recirculation units and/or UPO Deodorization.

Administrative and Support Areas

Whether located within the production area or in the offices, administrative areas, in addition to being more densely occupied, are also subject to contamination from pollutants from production processes or the circulation of people. These areas, which are normally cooled or heated, do not have suitable natural ventilation, threatening the health of the occupants by the presence of particulate, pollutant gases and microorganisms.
Studies show that the concentrations of volatile organic components (TVOC) especially formaldehydes from furniture and finishing materials, often exceed the acceptable concentration limits*. Infectious biological agents are also a considerable risk of contamination in more densely occupied environments, especially those serving the public. Often located in poorly ventilated environments due to air conditioning, these areas can greatly benefit from Purefeel’s UPR air purification and recirculation units and/or UPO Deodorization.

Laboratories

– Air conditioning systems equipping laboratories, as a rule, often have the side effect of decreasing the quality of indoor air due to reduced outdoor intake rates and filtering capacity*. Although most of the alternatives available on the market for indoor air purification are intended the to laboratories, few or perhaps none, in fact, meet the essential control, monitoring and management requirements needed in this type of application (see INTELIARTM). Infectious biological agents are also a considerable risk of contamination in laboratories more densely occupied or which have specific control requirements in this regard. Often located in poorly ventilated environments due to air conditioning, these areas can greatly benefit from Purefeel’s UPR air purification and recirculation units and/or UPO Deodorization.

Health Care Areas

Clinics, Hospitals, Community Health facilities, small Clinical Analysis Laboratories and related environments operate in buildings with poor ventilation conditions, putting occupants’ health at risk. These buildings in general do not support the installation of centralized ventilation systems without complex and expensive works. At the same time, maintenance and control of air quality is essential. Infectious biological agents are a real risk of contamination in such environments. Purefeel’s UPR air purification and recirculation units are a technically consistent and economically viable alternative in these cases.

Commercial and Public Buildings

The increasingly frequent spread of epidemics and pandemics has greatly restricted the use of spaces for the intense circulation of people in private and public buildings. Part of the environments in these buildings, which quite often do not have suitable ventilation system, has a high density of occupation with the consequent risks of contamination. In addition, indoor air pollution by airborne particulate and other toxic substances from both the external environment and sources of internal emissions, represent an actual risk to occupant’s health, especially in the long term*. Infectious biological agents are, in fact, a considerable risk of contamination in more densely occupied environments. Often located in poorly ventilated environments due to air conditioning, these areas can greatly benefit from Purefeel’s UPR air purification and recirculation units and/or UPO Deodorization.

Air Conditioning

The sophisticated IAQ-i algorithm that integrates Purefeel’s INTELIARTM Technology defines 3 levels of Indoor Air Quality: GOOD, AVERAGE and BAD.
That is performed using a thorough scoring method based on scientific criteria, depending on the concentration of monitored pollutants, temperature and humidity.

On the other hand, the intake of outdoor air is limited by air conditioning parameters. If any deficit in the cooling/heating capacity is detected, the system reports it automatically and records the information. It means that an indirect diagnosis of the air conditioning system may be obtained from the correct application of INTELIARTM.

When necessary, Purefeel works in close collaboration with its partners, specialists in the area of Heating, Ventilation and Air Conditioning (HVAC) in each region, for complete IAQ (indoor Air Quality) service to the Customer
