However, the market for air purifier filters is limited by the high maintenance costs associated with the equipment. In most cases, filters need to be replaced and maintained every four to six months. In addition, the lack of awareness among consumers about the hazards of polluted air is also hindering the market growth.
Air purifier filter manufacturers use a variety of materials and processes to create high-quality air filters. Plastic is used for single-use filters, while carbon and charcoal are used for heavy-duty applications. All of these materials are manufactured using a variety of techniques and are available in a variety of specifications. Some manufacturers even use a variety of materials for filters, including stainless steel, carbon, and foam.
For example, HEPA filters can filter up to 80% of airborne particles. Although there is no standard for HEPA filters, manufacturers test their products by using third-party labs and companies. The test procedure is based on standards established by the International Energy Standards Organization (IEST). When buying an air purifier, look out for the words "Conforms to Recognized Test Methods" or "HEPA Certified".
Filters are made of porous materials that trap and filter solid particles. They are often used in applications where air quality is critical. Of the most common filter types, fiberglass is the most popular. It is reinforced with a metal grille, which prevents it from being damaged. Polyester filters are more durable than fiberglass, while pleated filters are known for their superior dust resistance.
Air purifier filter manufacturers can customize filters for specific applications by considering the size, density, and type of air in a given environment. Some manufacturers can even customize the filter frame, media density and length. Choosing the right filter can have a huge impact on air quality.
Many air purifier filters contain HEPA filters. However, they do not remove volatile organic compounds (VOCs). The best air purifiers come with activated carbon pre-filters. Activated carbon is produced by heating a carbon source in the absence of oxygen. This process, called pyrolysis, separates pure carbon from other materials. It is then exposed to 1,500-degree Fahrenheit steam to activate the carbon particles.
Function: antibacterial, mites removal, odor removal, photocatalyst, cold catalyst
Application scenarios: Offices, shopping malls, schools, public places
HEPA stands for High Efficiency Particulate Air. It is a standard defined and developed by the U.S. Department of Energy during the 1940s as part of their efforts to contain the spread of particles and contamination resulting from nuclear testing. This standard has since moved into the consumer market and has become commonplace for air purifiers.
