Activated Carbon in Yakuso Air Purifiers:
I. Introduction
The presence of activated carbon in Yakuso air purifiers may be a mystery to you, unless you are a aquarium hobbyist, or own a water purification system which uses carbon. For many people, the first time they encounter it is in selecting home air purifiers. Although most of our customers begin their search because of allergies or asthma, many soon realize how much odors and the chemicals with can cause them also contribute to their respiratory problems. Thats why Yakuso air purifier systems also address these issues.
II. History and Use in Purification Processes
As many as 2000 years ago, human beings were using activated carbon to remove impurities from water. Even then its exceptional adsorption qualities were known. However, it was not until the early 1900s that it was produced in a form (as powder) that could be sold commercially. At that time it was used to purify water (so that it had no smell or taster) and to take the color out of sugar. As World War I got into swing it was discovered that it could be used in gas masks to protect soldiers, as well as for war time water and air purifiers. Instead of being used in powder form, granular activated carbon was developed. From that point on, activated carbon was used in many ways.
Yakuso netative ions
Negative ions help freshen and purify the air by causing allergens such as pollen, mold spores, dust, and animal dander floating in the air (which have either a neutral or a positive charge) to be attracted to and stick to each other, forming 'clumps' (because opposite charges attract) . These clumps of particles then become heavy enough so that gravity can pull them down to the floor, where they can be vacuumed up, rather than staying in suspension where they can be breathed in and cause allergic reactions.
