If you have been using traditional blackboard and chalks to teach your children or students and you really hate the way those chalks pollutes your home or classroom and deteriorates the overall health of your respiratory system and that of your students, you should consider replacing your old blackboard with new dry-erase board. In fact, a whiteboard has been used in many classrooms since a long time ago. Whiteboard becomes a more preferable medium for writing and teaching because of many reasons. First of all, whiteboard is much cleaner than blackboard. When you erase your blackboard, a significant amount of chalk residue will still be left on the board. When you clean your whiteboard, only a very small amount of or perhaps no ink residue will be left on the board. In addition, unlike whiteboard marker, chalk produces unhealthy dust and dirt when it is used for writing. Therefore, using whiteboard is safer for your health than using blackboard. Last but not least, anything that you write on a whiteboard is much clearer than that written on a blackboard.
As hypo-allergenic alternative for blackboard, high quality dry erase board quickly gains popularity among its users. Today, several types of whiteboard can be found in the market. Based on their price, whiteboards are available as cheap whiteboards, which are made from a cardboard core that is coated with melamine resins; semi expensive whiteboards, which are made from steel core sheathed with polyester; and expensive whiteboards, which are made from enameled steel board. You can buy any of those whiteboard types either offline or online.
Erasing anything that you write on a whiteboard is as easy as writing on it. Most magnetic dry erase boards use magnetic eraser to erase anything written on them. By using magnetic eraser, no ink residue will be left on the board.
