What is TVOC?

People use TVOC to describe common pollutants in the air, and many air purifiers also claim to filter TVOC. What is TVOC? What are the effects of TVOC? How can air purifiers effectively filter TVOC from the air? All you need to know about TVOC can be found in this Blog.

What is TVOC, VOC?

TVOC, Total Volatile Organic Compounds, is the summation of all VOCs. They are a group of compounds with high vapor pressure and low water solubility. TVOC represent a very important class of pollutants that are present in various kind of industrial streams. It includes a wide variety of chemical compounds such as alcohols, aldehydes, ketones, aliphatic and aromatic hydrocarbons, etc.
According to WHO,VOC moistnessbe produced by fuel burning, paint, metabolic action, pesticides, insecticides, and fungicides.

The Harm of TVOC

TVOC affect our sense of well-being, and some VOCs are even bad for health. Besides, some people -especially children and elderly people have a higher sensibility than others.
Immediate symptoms that some people have experienced soon after exposure to VOCs are

  • Headaches
  • Dizziness
  • Nausea
  • Eye, nose, and throat irritation
  • Coordination loss
  • Fatigue

Some VOC’s (as toluene) cause irritation at normal levels, eg allergic skin reactions. Bad odor and stale air are uncomfortable and affect people’s feeling of cleanliness.
Some VOC’s as formaldehyde can cause cancer. VOC’s for a long-term exposure in large doses can damage liver, nervous system, and kidneys.

NanoGuard™ Filter

After years of development and countless times of tries, Smartmi developed a technique that weaves ultra-thin organic fibers closely together in the filter. Through plasma electret technology, the woven fibers from Smartmi Nano Guard™ filter are polarized to create a static effect that catches even smaller pollutants atop of physical filtering, while the intricate nano-network structure catches the particles in the air and lock them down on the surface to prevent pollutant escapement.

The result? More efficient in air purification than traditional HEPA filter.

The testing results indicated that after 60 mins of air purification, Smartmi Nano Guard™ Filter was able to capture 99.99% of 0.1μm pollutants like smog/dust/pollen/bacteria, etc.

Smartmi NanoGuard™ Technology-Coal Active Carbon


Also, NanoGuard™ filter‘s material chooses coal active carbon with bigger surface area. 10g of coal active carbon can cover more than 11500m² of area, equivalent size of 1.5 standard(7140m²) soccer fields, absorbing more odor/TVOCs.
