Standard Filters
Standard Filters were designed to correspond with all the standard sized fans. Filter shapes available are square, rectangle or round. Custom filters have case specific designs to fit your case exactly. Both these categories may be ordered in either black or white filtering mesh and the filter frame in any color or metallic finishes. As new trends emerge so this range will be adapted. What is considered custom today might become standard tomorrow. The filters above are what the standard range consist of currently.
Electronic Air Filters
There are two types of electronic air filters available. The first is called an electrostatic precipitator, which uses static electricity to collect charged particulates such as dust and animal dander in its collector plates, which need to be cleaned occasionally. The other type is called an ion generator, which charges the air with ions---negatively charged particles---that bind to the positively charged allergens, making them heavier. The particulates will then settle more quickly on surfaces to be cleaned or vacuumed up.
