What is Indoor Air Quality

"Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.

Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.

Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later."

The Impact of Indoor Air Quality

From our physical well-being to our emotional state of mind, ability to concentrate, focus, and effectively perform our daily activities air quality has a strong impact on our lives.
Poor indoor air quality can lead to short-term effects such as congestion, sore throat, dizziness, coughing, among others.

Continued exposure to poor indoor air quality conditions can result in long-term effects such as chronic respiratory diseases, neurological disorders, cardiovascular diseases, and others.

As the air conditioning and construction industries evolve new standards help improve and maintain our indoor air clean and fresh, tighter envelopes, better materials, and adequate ventilation. Older standards on the contrary, insufficient maintenance, and natural or involuntary sources of contaminants can be a driver for poor indoor air quality.

Key Elements of Indoor Air Quality


People define critical parameters of indoor air quality.  Children have different needs than the elderly; people with allergies also have different needs than those without them.  Understanding the specific needs of the home/office inhabitants is the first step in achieving proper IAQ.

Contaminants come in different forms, some occur naturally such as dust, pollen, bacteria, viruses, mold, radon, CO2; other contaminants are human-generated such as chemicals, volatile organic compounds (VOCs), formaldehydes, asbestos, pesticides, etc. A key element of IAQ is understanding contaminants and eliminating or controlling their sources.

HVAC System

The heating, ventilation, air conditioning (HVAC) system is critical in achieving an ideal IAQ.  The HVAC system will control temperature, humidity, fresh air, air velocity, air distribution, pressures, and will (should) incorporate an adequate filtration/purification mechanism for the air stream.

How To Improve Your IAQ

Here are several actions that you can take, some of them today, to improve your air quality:

1. Check your air filter
Change periodically to ensure effectiveness, also check that the type of filter is adequate for your specific needs (MERV rating).

2. Eliminate internal sources of contamination
Move strong chemicals away from your living space into a safe place. Examples include bleach, disinfectants, solvents, paint, glue, and other chemicals. Remove items that may be degrading, especially old pieces of furniture, ornaments, stored items, old rugs, boxes, among other.

3. Clean frequently
Dust furniture, curtains, shutters; vacuum rugs, sweep or mop floors.

4. Ensure proper ventilation
Modern AC systems introduce fresh air periodically; if your system does not have a make-up air device open your windows periodically to allow fresh air in your home.

5. Avoid artificial freshening products (sprays, atomizers) and candles.
While they may provide a temporary pleasant smell and provide a sense of freshness they can release unwanted chemicals and particles.

6. Seal your home
Avoid infiltration of pollutants by applying caulk in windows and door frames; ensure that door sweeps are in good condition, as well as exterior door frame seals.

7. Install a smart thermostat
Set a comfortable temperature range, include a schedule to minimize energy consumptions while you are sleeping or away.

8. Manage relative humidity
Ideally, relative humidity of your conditioned space should be between 30% and 50%.  Most air conditioners though don’t have means to control relative humidity.  If possible, consider investing in add-ons that help you maintain relative humidity within this range. 

9. Install a central air purifier
Technology exists today to remove up to 99% of bacteria, viruses, mold and yes, COVID-19.  Central air purifiers also degrade formaldehydes and unwanted chemicals released by construction materials and regular household items.
