Air filters come in a lot of different sizes, but one uncommon size of air filters that Nordic Pure manufactures are the 28x30x4 air filters. We believe we offer the best air filters available because of the quality and attention to detail we use while manufacturing them. We have been manufacturing air filters since 1960, and because HVAC systems have advanced through the years, we have trekked the same course and improved our filters too. Nordic Pure provides manufacturer direct, lower prices than our competitors, and you receive free shipping on all orders! Try them, and we are certain you’ll be pleased with our great filters.
The common fiberglass air filters found in home improvement stores are created to only trap large-sized air born particulates. They also release fiberglass fibers into the air. Nordic Pure air filters are made out of an electrostatically-charged synthetic material. Because our filters have an electrostatic charge, the filter media draws airborne particulates to it as a magnet does with metal. Electrostatic filters do the best job in trapping airborne particles, and protect your family from allergy causing pollen, fine dust, tobacco and cooking smoke, airborne plant spores, bacteria, and some viruses.
Not only are our 28x30x4 air filters MERV 12 filters, but all the filters we manufacture are. MERV stands for Minimum Efficiency Reporting Value. This is a number that has been assigned to filters which is intended to help you compare air filters that are used in heating and air conditioning systems. The higher the number the greater efficiency at removing airborne contaminates from the room. A MERV 12 rating represents the best balance between airborne particulate removal of dust, pollen, airborne pathogens, etc. and overall HVAC system efficiency. Air filter above MERV 12 generally require larger, more expensive HVAC systems not normally intended for traditional home or smaller office heating and air conditioning systems. This is due to the "drag" imposed on the HVAC system. Top-notch HVAC professionals, who buy from us daily, highly endorse the MERV 12 rating as providing the highest efficiency of air filters for house or small office, while not putting a strain on the HVAC system.
Changing your air filter is the first step in insuring your HVAC system runs at its optimal level this season. We recommend checking your air filters monthly to make see how often a filter change might need to happen. Generally , you should change your air filters every 30, 60, or 90 days. Particles in indoor air that pass through the air filters are measured in microns, which are 1/1000 of a millimeter. A human hair is about 100 microns wide. Regardless of the purpose, whether it is used as air conditioner filters or furnace filters or used in a combination HVAC system, a Nordic Pure air filter captures airborne particles as small as 0.3 microns! Nordic Pure air filters do not kill germs, however, the material our air filters are made out of does not permit the growth of bacteria or mold. As a result, it is not necessary to add any potentially irritating chemicals to the air filter to kill germs. Odors are most often a combination of gas and particulate. Nordic Pure filters do not remove the gases but can remove the particulate.
