Pollution from power plants, cars, and other transportation is a well-known contributor to outdoor air pollution.

We usually think of air pollution as being outdoors, but our indoor air quality is often worse; it can be up to 10 times worse for you than the air outside. Sources of indoor pollution include biological contaminants like mold and pollen, household products (paint, floor polish, etc) and pesticides, gases such as radon and carbon monoxide, and materials used in the building such as asbestos, formaldehyde and lead. Microbial pollutants like mold, pet dander and plant pollen can combine with chemicals like radon and volatile organic compounds (VOCs) to create a pretty toxic environment in your home; since we spend an average of 90% of our time indoors and 65% of our time inside our homes, according to the National Safety Council, that can add up to allergies, asthma and worse.

Asthma is a rapidly growing public health problem. About 23 million people, including 6.8 million children, have asthma and 12 million people report having an asthma attack in the past year. Asthma accounts for nearly 17 million physician office and hospital visits, and nearly 2 million emergency department visits each year.

According to WHO (World Health Organization), indoor air pollution is responsible for 2.7% of the global burden of disease.

According to ALA (American Lung Association), poor indoor air quality can cause or contribute to the development of chronic respiratory diseases such as asthma and hypersensitivity pneumonitis. In addition, it can cause headaches, dry eyes, nasal congestion, nausea and fatigue. People who already have respiratory diseases are at greater risk.

In 1914-1918 the introduction of poisonous gases into the battlefields of the First World War gave great impetus to the development of large-scale production methods for adsorbent carbons suitable for use in military respirators. Granulated carbons, with adequate adsorptive powers and providing low resistance to air flow through the respirator canister, were developed by activating wood chips with zinc chloride. These were first manufactured carbons with reliably controlled adsorptive and physical properties. A group studying under Chaney in the USA examined a wide range of precursors intended to produce adsorbents for gas-mask canisters. They determined that coconut shell yielded the best combination of required characteristics in the resulting carbon.

Post-1918 The wartime developments to mass-produce activated carbons with closely controlled characteristics lead to post-war expansion in the commercial production and application of carbons. In Europe considerable progress was made in the manufacturing of active carbon from new raw materials. Coconut and almond shells with zinc chloride yielded active carbons with high mechanical strengths and adsorptive capacities for gases and vapours.

The material of the carving products is 'activated carbon' (Charcoal). This material has a highly porous nature along with a large surface area, which makes it an ideal absorbent for all kinds of poisonous gas. It works especially well to cleanse indoor air from carbon monoxide, formaldehyde, benzene and similar gas, ammonia, niton, sulfur dioxide and other smog or smells, to help purify the air and eliminate pollution.

Pure Dynasty charcoal carving art is a completely natural and environmentally friendly product. There is no energy exhausted in the process of physical absorption and it does not create a second pollution to the environment, thus it has no poisonous effect or other side effects.

The normal service life of our product is 8-10 years, after which you can replenish the product by exposing the charcoal crafts under the sun for 3-5 hours every 3 years.

Pure Dynasty charcoal carving art has great artistic additive value because they are made by artisans who adopt hand carving and painting techniques. Pure Dynasty charcoal carving art can be widely displayed in family homes, hotels, offices, automobiles, to name just a few. It does not only have the capacity to purify indoor air but also beautify your environment.
