What is Indoor Air Quality (IAQ)?

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.

Common Pollutants are shown as below:

Wood Furniture

Formaldehyde

Generated from wood furnitures, paints and adhesives. It causes irritation to eyes and respiratory system.

Bacteria

From human or animals through breathing, sneezing or coughing. which cause dizziness, fever, digestive problems and allergic.

Particulate Matters (PMxx)

From cooking stoves, factories and vehicles. which cause eyes, nose, throat and lung irritation.

Wall Painting

Volatile Organic Compounds (VOCs)

From paints, solvents, consumer and aerosol products, It caused irritaiton, headaches and dizziness, some are carcinogens.

Mould

Dust and moisture cause mould growth on wall surface, it will cause health problem like allergic and irritant to eyes and respiratory system.

Solution 1:
Electrostatic Filtering

Electrostatic filtering gives particles and electrical charge so that the impurities in the air stick to the filter like socks in the clothes dryer.

Because the particles are sticky, the fibers in the filter can be farther apart, so lessenergy is needed to push the air through, the Clean Air Delivery Rate (CADR) is higher,the air purifier makes lesser noise and the filters last longer.

Solution 2:
Ultra Violet (UV) Light

Ultraviolet (UV) light is a range of light frequencies that are mostly invisible to the human eye. The UV-C band is most effective at killing germs because its short ultraviolet UV wavelength is able to penetrate the cell walls of microorganisms and scramble their DNA.

Solution 3:
Negative Ion

Active filters are very easy to switch the harmonics of the power line without depending on the reactive power of the basic frequency. These filters use an outstanding technique wherever the filter utilizes self-generated harmonic components & infuses this into the power line to cancel the unnecessary harmonics.

What is Negative Ions?

 “Generally speaking, negative ions increase the flow of oxygen to the brain; resulting in higher alertness, decreased drowsiness, and more mental energy,”
Pierce J. Howard, PhD, author of The Owners Manual for the Brain
