Does your building suffer from air sickness?

Indoor air quality (IAQ) has become one of the most urgent environmental issues of our time. OSHA estimates that 30 percent of all Americans working in commercial buildings suffer from bad air. EPA studies warn that the levels of indoor air pollutants may be two to five times higher than outdoor levels. Regulatory measures -and a sharp rise in litigation- have prompted building owners to improve air quality, monitor IAQ levels, and keep accurate records of their progress. The PureTrac System offers continuous IAQ monitoring. Our web-based solution for tracking and reporting indoor air quality can help you maintain a healthy building environment. The PureTrac System is unique in its ability to continuously measure, track, record, and report in real-time indoor air quality conditions, alerting you to environmental changes before they become problems. Come to us for the right diagnostic tools. You can't manage what you can't measure.

Pure Choice History

PureChoice has been developing and using IAQ sensing and data management technologies since 1992. To date, we have logged hundreds of thousand IAQ monitoring hours. PureChoice formed  in 1992 to provide customers with the technology and equipment to deliver clean air and water. As their business grew, a number of their clients requested help in monitoring the quality of their air and water resources. The PureChoice scientists and engineers developed the software and hardware that together form the patented* PureTrac Air Monitoring System, an efficient and easy-to-use environmental information network. The system is the industry leader in its cost-effective design and operation, application of new technologies, ease of use and high degree of customer satisfaction. PureChoice formed partnerships with distributors to install and support PureTrac Systems and with utility companies to handle customer service, billings and collections. Together, PureChoice and its partners are able to offer complete solutions to customers who want reliable environmental information 24 hours a day, 7 days a week. The collected IAQ data can be used to validate building control performance, guide maintenance scheduling, adjust ventilation rates, reduce overall energy costs and address regulatory, customer or employee issues. In short, PureChice is in business to help make life safer, more comfortable, more productive, and worry free. PureChoice and Air Filters Unlimited will do our absolute best to help you find air quality solutions that: Reduce health risks Replace expensive manual testing procedures Are tailored to your specific needs Save energy, cleaning, and utility costs Provide comprehensive environmental information in a clear format Generate measurable and documented records Are easily accessible on the Internet at all times, day or night

Most people are aware that outdoor air pollution can damage their health but many do not know that indoor air pollution can also have significant health effects. Studies of human exposure to air pollutants indicate that indoor levels of pollutants may be two-to-five times, and occasionally more than 100 times, higher than outdoor levels. These levels of indoor air pollutants may be of particular concern because most people spend about 90% of their time indoors - in schools, offices, factories and their homes. Without uniform and meaningful laws governing IAQ standards, PureTrac and the Nose Monitor are watchdogs of a building's environmental health. It's a technological advance that could make our lives healthier, safer and more productive. Contact Air Filters Unlimited today to find out information about The Nose.

The Nose

The Nose Knows

PureChoice's state-of-the-art Nose Monitor is a leading edge, indoor air quality monitoring technology, ideal for complete building automation control and compatible with most standard controls systems. The Nose is compact, about the size of a thermostat, and measures the five key indoor air quality (IAQ) parameters -- temperature, relative humidity, carbon dioxide, carbon monoxide, and odors and gases (TVOCs). The five sensors have been combined into a single-printed circuit board mounted in a thermoplastic housing. Five high-quality sensors in one package: PureChoice engineers selected the highest quality sensors available, with respect to price. Sensors are manufactured in America, Great Britain and Finland, resulting in very demanding circuit design, since each sensor imposes different power, signal and communication protocol requirements. The Nose's temperature and humidity sensors are contained in their own sub-chamber to isolate thermal interference that could be caused by the remainder of the circuitry. Patented software and hardware maintains precise temperature control of the carbon monoxide and VOC sensors to ensure minimal sensor drift. Microprocessors control the operation of all sensors, including thermal regulation, initial setup and calibration, conversion to engineering units, digital messaging and data transfer. All calibration and trimming are handled by digital communication with remote workstations, so the calibration environment is not disturbed. In addition, all other circuitry, microprocessor, memory and power conversion circuits were assembled on this same board.

The PureTrac System

Secure, state-of-the-art technology.

Electronic sensors or "Noses," placed strategically throughout a building, feed air quality readings to an on-site data interface. The sensors detect and monitor five critical variables: temperature, relative humidity, carbon dioxide, carbon monoxide, and odors/gases. A PureChoice Inc. central computer collects and processes the data and makes it available over the Internet. Clients view their secure data from any location, 24 hours a day. If readings should go beyond user-defined standards for acceptable IAQ levels, the system automatically sends out an e-mail alert. Comprehensive data collection for best IAQ practices. The PureTrac System continuously monitors indoor air quality in real time, around the clock, without interruption. Unlike other systems on the market that offer only random sampling, the PureTrac System gives you continuous visibility of building trends. The comprehensive database created provides a solid groundwork for benchmarking, modeling, optimization of air quality controls, and effective protection against legislation. Economical, reliable, and foolproof. The PureTrac System provides the information you need to ensure the right amount of ventilation and air filtering, guaranteeing the safety and comfort of building occupants while conserving every energy dollar. Whether you're building a new space or retrofitting an existing one, the PureTrac System offers you cost-effective options for IAQ management. Of all the systems on the market today, it most efficiently balances high quality, simplicity, and excellent value for optimum performance.
