The products in your home, even the building materials inside your home, likely contain harmful chemicals. For example, the antifreeze and windshield washer fluid in your garage include ethylene glycol which can cause respiratory issues if inhaled. Formaldehyde is in a wide range of products including some furniture, composite core doors, laminate floors foam insulation, disinfectants, cleaners, air fresheners, carpets, toothpaste, body wash, and more. Oils, furniture refinisher, paint, varnish, car and floor polish, pesticides, herbicides, insect repellent, plastics, leathers, and many other products contain harmful vapors like the chemicals listed below. It is important to ventilate these chemicals to reduce acute and long-term health risks.

S&ampP's Indoor Air Quality (I.A.Q.) Brand

Smart Fan for a Smart Life

S&P's IAQ sensor (PCIAQS) is the first thinking fan. A PC fan with IAQ Sense detects and extracts both Volatile Organic Compounds (VOCs) and moisture when installing with a Premium CHOICE Series Ventilation Fan.

The VOC sensor has an adjustable knob to set the sensing range based on the concentration of particles (ppm). The humidity sensor detects rapid increases in moisture at the ceiling level where steam and humidity naturally rise and automatically turns on the fan. You can set the IAQ sensor to run the fan at high speed if it senses VOCs or moisture, then after a specified amount of time, it will automatically adjust to run at low speed. The IAQ sensor also includes a speed control to change the fan at a percentage of full speed so the fan can be run continuously to meet code requirements. A PC fan with a PCIAQS is a fan you can trust to keep you, your family, and your home safe from harmful contaminants.

What does IAQ Sense Detect and Extract from the Air?

Today's homes are built to be tighter and more energy efficient than ever. Compact dwellings also mean that pollutants, dust, and moisture confined within the house causing poor indoor air quality. The EPA ( has stated that indoor air quality is often two to five times worse than outdoor air, and that indoor air pollution is among today's top five most significant risks to public health.

With IAQ Sense you can detect and extract the following harmful contaminants within your home:

  • Humidity (H2O)
  • Carbon Monoxide (CO)
  • Ammonia (NH3)
  • Acetone (C3H6O)
  • Benzene (C6H6)
  • Ethylene Glycol (C2H6O2)
  • Formaldehyde (CH2O)
  • Methylene Chloride (CH2Cl2)
  • Other Harmful VOCs
