About this course

Indoor air quality (IAQ) is the result of a combination of factors.  To improve it, you have to take a comprehensive approach that addresses the sources and types of pollutants that find their way into your indoor air.

In this course, you'll learn the 7 steps to good IAQ and the importance of each.  You'll get concrete advice on how to implement the strategies and the background knowledge you need to apply them in different situations.

Learning Objectives

  • At the end of this course, attendees will be able to name the types of pollutants best removed by filtration.
  • At the end of this course, attendees will be able to explain why "Build tight; ventilate right" is an incomplete prescription for good indoor air quality.
  • At the end of this course, attendees will be able to describe the 7 IAQ methods covered in the course.

Step 2. Airtightness

The steps are numbered but after source control, they're not in order of importance.  Step 2 is airtightness, and it keeps pollutants that are outside the house from getting into the house.

Step 3. Filtration

Filtration doesn't get near the attention it should get.  That's because of some misconceptions in the HVAC industry and because filters just aren't as sexy as air cleaners from a marketing standpoint.

Step 5. Moisture Control

Mold, dust mites, and some other allergens and air pollutants respond to moisture levels.  When you control the moisture, you go a long way toward controlling those pollutants.

Step 6. Pressure Balancing

This step is the hidden treasure.  Those of us trained in building science know about it, but many of those who work on homes—even some who deal with IAQ—can miss the importance of unbalanced pressures inside a home.

Step 7. IAQ Monitoring

If you're not measuring, you're guessing.  Why spend money to improve IAQ if you don't know if your work had any effect?

Air Cleaners

"Hey, my indoor air is bad, so I need a HEPA thingie or an ultraviolet zapper."  Unfortunately, this is what a lot of air cleaner marketing has led to.  This module covers pros and cons of air cleaners and how they fit into an IAQ plan...or not.
