Indoor Pollutants Cause Significant Health Risks


When we think of air pollution, we don’t really think the indoor air quality matters. But indeed we should. The Environmental Protection Agency (EPA) states that indoor levels of pollutants can be up to five times as concentrated as those found outside. We spend most of our time indoors and yet we never realise that the room’s indoor air quality is full of pollutants. Chemical vapours, mold, pet dander, cigarette smoke, you name it. These airborne contaminants can cause or exacerbate asthma and allergies. But don’t worry, there’s still technology to thwart indoor air pollution and ease the health problems.

HEPA Purifiers Reduce Health Hazards

Sweeping and vacuuming may well be one of the solutions. But it will at the same time stir the pollutants back to the air. There’s another immediate solution: HEPA air purifiers. HEPA filtration technology was developed in the 1940s by the U.S. Atomic Energy Commission to remove airborne radioactive contaminants. Now, HEPA filters have become a very popular technology to improve indoor air quality. They can effectively filter airborne contaminants as small as 0.3 microns. That’s even smaller than a red blood cell. HEPA air purifiers efficiently trap up to 99.97% of pollen, mold, and pet dander, among many other particles.

We can also use HEPA air purifiers together with an activated carbon filter. Activated carbon filters trap chemical vapors, volatile organic compounds (VOCs) and noxious odors which lead to poor indoor air quality.
