Furnace Filters come in a variety of sizes and types. The primary distinction between one filter and another is the size of the filter (length, width and thickness) and the filter material or "media" that is used in the manufacture of the filter. Nordic Pure features all of the popular sizes of furnace filters. Nordic can also make a filter for your system if we do not stock your size. All custom filters can be ready to ship to you within ten days to two weeks and usually costs about the same as many of our competitor's ready-made filters.
The air in a furnace system first enters the home through the air return where it passes through the air filter(s) and into the air handler, over the heat exchanger part of the HVAC system (where the air is heated) and out through the ductwork into the home. The circulation throughout the HVAC system is accomplished through a powerful blower system. Because the air filter for furnaces is the only device in the entire HVAC system capable of removing airborne impurities, it makes sense that frequent replacement of the furnace filter as well as careful consideration as to the type of air filter you use will directly impact the quality of your indoor air. Conversely, ignoring the HVAC system's air filter means you are allowing the entry of polluted air into the entire system, driving down operating efficiency, filling up ductwork with all dust, pollen, dust mites, etc. and other airborne pollutants while exposing the building's inhabitants to polluted air.
The most common type of filter for furnaces on the market is a panel furnace filter that uses fiberglass as the filter media. Fiberglass filters are very cheap and do an effective job at removing only the largest of airborne particulates. In addition to its limited ability to filter finer particulate, fiberglass is very brittle and can cause harm when handled. Further, there is a potential for the fiberglass fibers to break off and enter passing air creating a serious health problem. Nordic does not endorse the use of fiberglass filters, both because of their limited ability to filter the air, especially smaller particulate and the health implications.
Pleated filter for furnaces are much like disposable panel air filters in that the filter media is housed in a rigid panel but the difference is that the media material used to filter the air, as well as the way the material is mounted into the air filter box or frame is different. The filter media used in pleated filters most often resembles fabric and has the capability of removing significantly smaller particulate from the air. Further, when the filter media is integrated into the filter, it is pleated to provide more surface area for filtration. This pleating adds more than double the surface area of un-pleated filters. The net effect is that you end up with a filter that removes more of the particulate in the passing air AND has at least twice as much surface area. Combined, pleated air filters provide a significantly higher level of filtration.
Electrostatic pleated air filter for furnaces are a more highly evolved version of the pleated air filter. In addition to a higher quality media filter material and pleats for increased surface area for filtration, the term electrostatic pleated air filter means that the filter media material is electrically charged so that the media material acts much like a magnet to draw more particulate into the media filter material for more efficient filtration. Another benefit of the electrostatic material is that it does not permit the growth of bacteria, often a problem with other filters. Nordic manufactures and sells only electrostatic pleated air filters in a wide variety of lengths and widths with thickness from 1 to 5 inches.
