1. What does "IAQ" mean? "IAQ" stands for Indoor Air Quality. We tend to insulate our homes and make them airtight. The result - our homes are more economical to heat because heat losses and infiltrations are reduced to a minimum. The consequence - everything produced inside the home remains inside and accumulates, resulting in the deterioration of air quality. More and more illnesses are associated with poor air quality. 2. What can result from poor Indoor Air Quality? More and more illnesses are associated with poor air quality. We have only to think of the growing number of asthma and allergy cases. All types of gases, dust, viruses and bacteria contaminate the air we breathe. In addition, we consume oxygen and produce gases and humidity, while not renewing the oxygen consumed. 3. What types of pollutants can I find in my house? The following is a list of pollutants that can be found in most homes or vicinity:
4. What system do I need? First, evaluate your problem, identify your heating system, and select one of the air quality systems offered by "Imperial Air Technologies Inc." Installed by a ventilation specialist, any Greentek system will improve your comfort and air quality, while offering the peace of mind you and your family deserve. 5. How can you know whether you need a heat or an energy recovery system? If you use a heating system more often than air conditioning, you need an HRV. If the opposite is the case, an ERV is recommended. HRV: Contaminated exhaust air and fresh outside air pass through the heat recovery core in separate passages that prevent air contamination or mixture. The fresh outside air then absorbs the heat and warms up, and is distributed at a more comfortable temperature to the various rooms by the ventilation system. ERV: It transfers latent energy (humidity) from the most humid air current to the driest, while transferring heat. So in winter, the outside air will absorb the exhaust air's humidity, and in summer the reverse. 6. Can an HRV/ERV be installed in an older house or in new construction only? You can install an HRV/ERV practically in any home. In new homes, they are mostly installed during the construction with an independent ducting system depending on your HVAC system. In older houses, they can be installed directly on your existing forced air system, and using the same ducting they make a perfect addition to your HVAC system. 7. What is an air purifier? An air purifier is designed to work with your HVAC system to eliminate airborne contaminants such as moulds, bacteria, viruses, spores and biological odours, which are major causes of Sick Building Syndrome and allergies. 8. Why should I use an air humidifier? To answer in just two words - comfort and health. Humidity makes for a comfortable and healthful indoor environment. The ideal comfort zone in your home is between 30% and 50% humidity. According to physicians, dry air frequently causes dryness of the eyes, nose, throat and skin. With the right humidity level in your home, you will not only benefit from improved air quality, but you'll also protect your furniture, hardwood floors, floating floors, cupboards and moldings from cracking caused by the expansion and shrinking of materials. 9. Which IAQ product can be used for air movement? In line-fans represent a technically-perfect solution, uniting the advantages of axial fans – straight airflow and easy installation with high-pressure stability, low noise level and high efficiency of the radial fans. The wide range of Greentek indoor air quality in-line fans can be used for different types of application and can meet your specific needs.
