Indoor Air Quality

Indoor Air Quality Includes the Outdoors

By | HVAC, Indoor Air Quality | No Comments

No one thinks about this certain source of indoor air pollutants because it is the exact opposite of the indoors.

The Outdoors!

If the outdoor air around your home or building isn’t healthy, your indoor air will be affected. If your HVAC outdoor intake is pulling in air near a cooling tower, generator, plumbing vents, garbage etc.…that air is going to be filled with contaminants which is now freely flowing through your house. Even a loading dock upwind can contaminate the air your outdoor intake pulls from.

ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) has a standard to use when putting in HVAC systems. The standard recommends 25 feet between the intake and a cooling tower and a minimum of 15 feet to the nearest dumpster.

So, make sure the outdoor air is clean to help you control the indoor air.

PARTICLES: Just Because They Are Nearly Invisible, Doesn’t Mean They Don’t Matter

By | HVAC, Indoor Air Quality | No Comments

Air is seemingly empty to us because the human eye cannot see many of the particles floating around. Particles can be human skin scales, bacteria, viruses, soot, rust, pet dander, pollen grains, mold spores, car-tire particles and more. Particles can be smaller than .01 micron in size. A micron is one-millionth of a meter, and the human eye cannot see anything under 40 microns.

To put this in perspective, the diameter of a single human hair is about 100 microns.

Household dust can range anywhere from smaller than .01 micron to 10 microns. Mold spores can be 2 microns to 10 microns. Bacteria are normally 0.1 micron to 10 microns and viruses are even smaller. Animal dander can be 5 to 20 microns in size.

So, what does this have to do with healthy indoor environment?

Particles travel on airflows created by HVAC systems and ventilation and, the smaller the particle, the longer it remains airborne. Some are even permanently airborne. The longer it remains airborne, the more time available it can be inhaled deeply into the lungs. Bacteria and viruses carry diseases. Some cause asthma and allergy symptoms. These particles that we can’t see need to be filtered out as much as possible.

Products such as HEPA filters remove 99.97% of particles. Air purifiers can be beneficial but can also be detrimental. An air purifier that ionizes air or creates hydroxyl ions creates an irritating gas to provide that fresh air smell.

The best way to removes these particles is to remove the source altogether. For example, if mold spores are coming off an old rug, get rid of the rug.

Dirty Sock Odor After Turning on Your Central Air?

By | HVAC, Indoor Air Quality | No Comments

Summer is around the corner and we’ll be turning on our air conditioning. CAUTION: That dirty sock odor is an indication that the A/C unit has become contaminated with microbial growth. Whenever warm, moist air is cooled, water will form condensation and microbes like yeast, bacteria, and mold only need oxygen, moisture and dust to grow.

Airborne particles can be carried through on air flows throughout our houses and buildings causing allergies, asthma, and hypersensitivity pneumonitis, a potentially life-threatening respiratory illness.

HOW TO AVOID THIS PROBLEM?

Adequate filtration.

This is the most important. Without adequate filtration, A/C coils, drip trays, and fibrous liners become contaminated due to the dampness. Pleated media filters with a MERV rating of at least 8 are recommended.

But don’t forget to change the filters on the recommended schedule, otherwise even the very best filtration will become filthy. And it is always a good idea to have the HVAC systems inspected before you turn it on for the spring or summer.

One Remedy for Poor Indoor Air Quality – Proper Ventilation

One Remedy for Poor Indoor Air Quality

– Proper Ventilation –

Research indicates that the air in our buildings may be more polluted than the outdoor air, even in the larger, more industrialized cities. With many people spending as much as 90% of their time indoors, being familiar with the causes and sources of indoor air problems becomes crucial to those who are responsible for building maintenance. This is especially important if the occupants are the young, the elderly, the chronically ill, or suffer from respiratory or cardiovascular disease. If too little fresh air enters a building, compounds and pollutants will accumulate until they reach levels that can pose health issues.

 

Major causes of poor indoor air quality include:

  • Inadequate ventilation,
  • High humidity levels, and
  • An accumulations of gases or particles.

 

Compounds that release gases or particles include:

  • Oil, gas, kerosene, coal and wood
  • Tobacco products
  • Building materials
  • Furnishings
  • Damaged asbestos-containing material
  • Deteriorating lead-based paint
  • Wet or damp carpet
  • Pressed-wood products and furnishings
  • Personal care products
  • Household cleaning products
  • Dirty or damaged HVAC systems and related ductwork
  • Dirty or damaged humidifiers
  • Pesticides
  • Outdoor pollution

 

Proper ventilation increases the quality of the air that our building occupants breathe by diluting emissions from indoor and outdoor sources and by exhausting the pollutants out of the building. Regulating the temperature and humidity to proper levels also reduces the concentration of pollutants, particularly mold. To improve air quality, focus on source control and ventilation improvements, and consider adding air filtration systems.

What is Carbon Monoxide?

By | Indoor Air Quality | No Comments

Carbon Monoxide

 

Are you experiencing headaches, fatigue, shortness of breath, nausea or dizziness?

 

Flu-like symptoms like those mentioned above are the initial symptoms one would experience in a carbon monoxide poisoning.  You will not see or smell anything.  Carbon monoxide is an odorless, colorless, invisible gas typically produced by burning fuel.  Carbon monoxide can become fatal when there are high concentrations indoors.

 

Carbon monoxide is produced by burning fuel:

  • when cooking or heating with fuel-burning appliances,
  • when running a car or generator indoors, or
  • when burning charcoal indoors.

The best way to prevent carbon monoxide poisoning is to keep all potential sources like those listed above in good working order.  Improper use of fuel-burning appliances or equipment can cause fatal concentrations of carbon monoxide.

  • Always follow manufacturer’s directions for safe operation.
  • Inspect and service equipment regularly.

Additionally, carbon monoxide alarms with battery back-up should be installed near sleeping areas and tested regularly.

 

If you suspect you are experiencing poisoning by carbon monoxide, immediately get fresh air and medical attention.  Notify the fire department to determine if and when it is safe to re-enter the building.
