Indoor Air Quality

How an ERV Can Help Improve Your Indoor Air Quality

You washed your hands - You washed your surfaces - Have you "washed" your air?

At Marlin Air Systems, we are experts on indoor air quality (IAQ)! By adding an Energy Recovery Ventilator (ERV) onto your existing air conditioning and heating system, it continually brings in pure fresh outdoor air and pushes contaminated stale air out. We strive to exceed your expectations by ensuring that each of our clients receives individualized service. We will provide you with a full complimentary consultation to explain available options, work together and choose the system that's best for you.

Where your air conditioning "stops," ERVs begin...

ERVs are Cost-Effective and Energy-Efficient (GREEN)

An air conditioning and heating system supplemented by an Energy Recovery Ventilator (ERV) can efficiently transfer energy from the exhaust air to pre-heat or pre-cool the 100-percent outdoor air to near room temperature.

The "Lungs" of Your Home or Office

Air conditioning and heating systems are the "lungs" of a home or building. Dander (pets, pests), dust, chemicals (VOCs, aerosols, paint, carpet, bedding, mattresses), smoke (cooking and other) and more are constantly recirculated through a typical system. Some believe an air conditioning system brings fresh air inside but this is FALSE! Only with an Energy Recovery Ventilator (ERV) added onto your existing system can you bring fresh pure outdoor air inside and force contaminated stale air outside.

The EPA names deficient indoor air quality (IAQ) as a Top-Five health Risk and people spend on average 90% of their time indoors! Ventilation with outdoor air is key.

Better Health

Whole Structure vs. Portable Air Filters

Allergies? Asthma? COPD? Migraines? Pets? Seniors? Children?

Poor Indoor Air Quality (IAQ) can cause allergies, headaches, coughs, asthma triggers, skin irritations and other breathing difficulties, as well as cancer, liver disease, kidney damage and nervous-system failure.(2)

Newer structures are more air tight (weatherized) and have the potential to hold in air pollutants. The Environmental Protection Agency (EPA) warns, "consequently, after weatherization, concentrations of indoor air pollutants from sources inside the home can increase.”(3)

Whole Structure vs. Portable Air Filters

An ERV is connected into your central air conditioning duct work and is continually changing out ALL the air in the home or building with 100% fresh, clean, pure air from outdoors and pushing the contaminated stale air back outside.

Portable room-size units filter stale, recycled air in one room. Filters must be maintained and/or replaced consistently to be effective. Portable air filters can be effective only for the room size listed in the manufacturer's recommendations.

Typically, multiple portable air filters are required for a home so air from one room doesn't contaminate air in the next room. This can be a lot of maintenance depending on the number of units and individual filters can be pricey to replace.

Even with portable air filters cluttering up your home, the fact is you're still recycling old air and not bringing in fresh outdoor air.

Better Focus and Productivity

Whole Structure vs. Portable Air Filters

Staying indoors more often? How clean is the air you breathe? How does it affect your performance?

In a study done in a lab at Harvard and Berkeley, they found “statistically significant and meaningful reductions in decision-making performance” at CO2 levels found in typical indoor locations such as homes, schools and offices.(4)

The study concludes that we must "keep inside levels [of CO2] as close as possible to levels outdoors through greater use of outside air."(4)

Sick building syndrome (SBS) is a condition named for illness attributed to poor indoor air quality that's thought to be caused by being inside a building or enclosed space. The Consumer Product Safety Commission (CPSC) also has extensive information on indoor air quality pollutants in buildings and homes.(5)

DON’T BREATHE EASY: THE ADVERSE EFFECTS OF POOR INDOOR AIR

by Nick Agopian*

"What Causes Poor [Indoor Air Quality] IAQ?

Think of inside air as a soup. Its quality can range from being like a consommé, when it’s relatively clean, up to a goulash, when it’s full of gases, particulates and other contaminants.

What are the reasons for this build up?

The main causes of poor IAQ include: • Not enough ventilation • Lack of fresh outdoor air inside • Poor maintenance of heating, ventilation and air conditioning (HVAC) systems • Dampness and moisture damage due to leaks, flooding or high humidity • Occupant activities • Construction and remodeling • Mold spores, dust mites and pet dander • Off-gassing of contaminants (a process that can last for years) A lack of sufficient ventilation in any indoor space is the main cause of the build up of contaminants, which are off-gassed from a variety of sources, including: • Construction materials • Furniture • Textiles and fabrics • Carpets • Paints, sealants and finishes • Cleaning supplies • Ourselves (we off-gas just like a car engine) • Our clothes • Chemicals on us left over from using shampoo, soap, cologne, shaving cream, etc.

Poor IAQ is also caused by the accumulation of gases like radon and carbon dioxide (CO2)...CO2 is emitted by humans as we exhale, and will gradually increase as the day progresses and reach unhealthy levels – especially in crowded buildings. Further, adverse effects are magnified when it’s cold outside due to increased building insulation and in newer construction because of improved sealing integrity that prevents outside air from getting in. In fact, the World Health Organization (WHO) estimates that 30 percent of all new or renovated buildings contain inside air that’s of poor quality."

Poor indoor air quality (IAQ) is a serious problem.

In fact:

- According to the Environmental Protection Agency (EPA) indoor air is two to five times – and occasionally greater than 100 times – more polluted than outdoor air

- The EPA ranks indoor air pollutants among the top five environmental risks to public health

- On average, Americans spend about 90% of their time indoors

- Poor IAQ can cause health problems, reduced employee productivity, poor student performance and discomfort inside homes

- Studies have shown that the overall cost to the U.S. economy of poor IAQ is $168 billion per year
