How Delta’s Indoor Air Quality Solutions Protect Your Family’s Health

Bangkok, Thailand, March 8, 2019- The recent cloud of toxic smog that blanketed Bangkok’s skyline and choked our lungs was a harsh wake-up call for everyone in the country. Now donning an industrial-grade face mask on the streets might make you feel safer, but did you know that the air we breathe every day at home, school or the office can be just as unhealthy? So how can we protect our health and prevent the air in our homes from becoming a deadly cocktail of airborne pollutants? Let’s take a look at why we need proper indoor air quality solutions in our modern lives and how they protect our whole family.

An Invisible Threat Lurking Indoors
Every day, we spend the majority of our time indoors at home and in other buildings for work, study, leisure and rest. The World Health Organization (WHO) claims indoor air quality plays a significant part in our general state of health, especially for children, elderly people and other vulnerable groups. The US Environmental Protection Agency (EPA) warns that chronic exposure to indoor pollutants can have dire long-term effects like respiratory diseases, heart disease and cancer.  

Sources of Home Air Pollutants
The British Electrotechnical and Allied Manufacturers' Association (BEAMA) warns of “Toxic Home Syndrome”, when poor air quality inside the home makes health deteriorate, and blames pollutants such as:
• Biological Pollutants: including mold spores and pollen
• Volatile Organic Compounds (VOCs): chemicals inside many cleaning products and air fresheners
• Gases: including natural radon gas and carbon monoxide that comes from cooking, smoking or burning candles and incense
• Building Materials: including paints containing lead and formaldehyde and asbestos materials
BEAMA also offers a list of tips to ensure a healthy home, with proper ventilation at number one. The association recommends homeowners install a mechanical ventilation system to make sure there is effective ventilation throughout the home. 

Growing Ventilation Crisis in Thailand
A Mahasarakham University study indicated that since Thailand implemented legislation for building energy conservation, an increasing number of buildings have adopted energy-saving measures. These new energy-efficient buildings have more airtight construction as air-conditioning or chilling systems typically account for 50-60% of the total amount of building energy use. Reduced air exchange rate results in deteriorating indoor air quality from a buildup of trapped indoor pollutants, dust, bacteria and even viruses while opening windows or using ventilation systems with inadequate or no filters exposes home occupants to outdoor air pollution as well. 

Delta Energy Recovery Ventilation
To overcome Thailand’s ventilation challenges, Delta has developed the Energy Recovery Ventilation (ERV) air exchange solution that quietly and efficiently supplies and circulates cooled and purified oxygen-rich air from outside while removing hot indoor air laden with CO2, viruses and pollutants. Unlike traditional ventilators, Delta’s ERV has a heat-exchanger core that pre-cools air passing to the inside while returning moisture from air passing to the outside. This technology can reduce outside air temperature by up to 6°C and humidity by up to 16% to help save up to 30% of energy usage for air conditioning in tropical Thailand. The ERV also has multiple High-Efficiency Particulate Air (HEPA) filters that use interception, impact and diffusion methods to filter out PM2.5 at a rate of 97%.   
   
Delta Indoor Air Quality Solution
The clean, cool and dehumidified air from Delta’s ERV can then flow out to each room via diffusers while exhaust fans powered by Delta’s leading DC motor technology draw out polluted air to discharge outside the home. Fan efficiency and noise levels play a key role in the effectiveness of ventilation systems. A case study by Zero Carbon Hub found many home ventilation systems had low effectiveness because of fan underperformance. In addition, some homeowners found their systems too noisy and switched them off rendering them entirely useless. In contrast, Delta’s portfolio of brushless DC motor exhaust fans have efficiency features like dual speed and motion sensing and a silent operation design to guarantee a safe and comfortable environment in your home.

Fresh and Comfortable Air Makes Healthy Homes
At the end of the day, your family can return to a safe, green and comfortable home with pure airflow quietly delivered and managed by Delta’s indoor air quality solution. Besides guaranteeing more happy years of healthy living and improved quality of life for your loved ones, Delta’s ERV and DC motor technology offers maximum energy savings that protects our environment and reduces your maintenance and running costs. Delta looks forward to enriching your life and supporting your dream of having a more livable, safe and green lifestyle in Thailand.
