Air Filters

Air filters are designed by air filter manufacturers to remove a range of contaminants from the air, including molds, gases, dirt and odors. There are specific air cleaner filters available for different needs, for not all filters are designed to remove the same particles. Filter efficiency is determined by a few different factors: the size of the filter fibers, the density of the fibers in the filter and the velocity of the air that moves through the filter.

Air filters are devices used to minimize or remove unwanted particulates from the air flow within a ventilation system or space to improve air quality and to extend the working life of machinery, engines and appliances. Filters are typically composed of a fibrous material which is constructed in a screen through which air is moved. Air filter manufacturers design air cleaner filters for different needs and filtration standards. The particles to be removed from the air can range from dust to pollen to mold spores to animal dander and other unwanted molecules carried by air. Types of filters include inline filters, membrane filters, air compressor filters, HVAC filters and more which are simply constructed devices incorporated into a wide variety of everyday applications. Specialty filters such as carbon air filters or exhaust filters can be used to remove other contaminants such as gases and odors from air streams. In medical applications, filters can be used to remove bacterial and viral microbes and infections which are transported through air molecules. HEPA air filters and ULPA filters provide the highest level of filtration, while other filters such as foam filters or vacuum filters provide lower levels of air purification but are perfectly adequate filters for many applications. Electrostatic filters provide an almost permanent filtration screen solution and do not require a power source in order to be most effective. Most types of filters can be custom fabricated to an extent in order to meet specific requirements.

When determining the most suitable type of filter to use for any given application, there are a number of factors to consider. Filtration efficiency is determined by the size of the material fibers and their length, as well as the density with which filter fibers are placed within the filtration unit. Dense filters will capture more particles and therefore provide a higher level of air purification, however will require more power in order to push the air through the filter. Therefore air velocity is another factor to be considered. Air filter manufacturers use various materials to make the variety of air filter types available. Fabrics, for example, are used in many types of filters such as membrane filters or paper can be used as a disposable filter option. Metals such as stainless steel are also constructed into filter screen for heavier duty filtration requirements. Alternatively other filters, such as carbon air filters utilize chemical reactions within the filter itself to attract and remove harmful elements from the air. Plastics are used in electrostatic filters to create the natural static charge from friction which attracts dust particles. There are specific air cleaner filters available for different needs, for not all filters are designed to remove the same particles.

HVAC filters are largely used in home or commercial heating ventilation and air conditioning systems (HVAC). The more researchers learn about harmful particles and substances that exist in the air, the more air filters play an important part in society's long-term health. Particularly beneficial is the use of air filters in domestic environments in which there are pets or excessive mold, mildew and dust that bring on allergic symptoms. Air filters help clean the air and remove these allergy-causing particulates, thus allowing home-owners and their families to breathe easier. The incorporation of filters into a circulation system is especially important for those prone to asthma or persons with breathing difficulties. A HEPA (High Efficiency Particulate Air) filter is an example of a specific style of filter used in HVAC systems which is able to remove the highest amount of unwanted particulates from an air stream. A HEPA air filter is mainly used to remove miniscule particulates such as allergens and other common irritants from the air and therefore is commonly used in critical applications such as hospital operating rooms and pharmaceutical facilities. ULPA filters are also highly efficient and very common. HEPA and ULPA filters are commonly used to eliminate harmful allergens. Strict air quality guidelines in many government and industrial circles make the use and continued innovation of air filters essential.

In addition to these uses, the automobile industry uses air filters extensively in vehicles to help promote engine hygiene. Exhaust filters and inline filter are common engine components. Some domestic and industrial appliances house their own internal air filters to increase air quality. Clean air within individual machines ensures longer life to the units. Examples of these types of air filters are found in vacuum cleaners and humidifiers. Air filter manufacturers create their products to protect machines like cars and air conditioners from damage and premature breakdown. Air compressor filters, for example, are vital to the longevity of direct air machines such as nail guns. For the most part, air filters that deal with large particles and high velocities have large filter fibers, and likewise, air filters that deal with small particles and low velocities have small filter fibers. To ensure that an air filter will work properly in its intended application, make sure that the design, density of media and fibers and possible adhesive are taken into account before purchase. Air filters are generally able to function very well, as long as they handle the right kind of particulate for their design. If well maintained and regularly cleaned, many filters will outlast their intended replacement date and will provide years of reliable performance and cleaner air.

Understanding the Uses & Benefits of Air Filtration Systems

An air filtration system is a mechanism that is used to mitigate the effects of solid pollutants, such as dust and mold, and microscopic organisms such as bacteria. Air filters are used in areas that require clean and quality air. Air conditioning systems, HVACs, and central ventilation systems are some of the most common applications where filtration systems are used. Airplanes, space crafts, submarines, and rockets also air filtration systems to protect the inside environment from harmful elements.

Air filtration systems have also become almost a necessity for all manufacturers due to the rising level of pollutants in our environment. Recent studies have indicated air pollutants in indoor environments are one of the top five reasons behind some major occupational health risks.

The American Society for Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has proposed a rating standard to evaluate and rate the efficiency of air filtration systems. This rating system is named Minimum Efficiency Reporting Value (MERV), and the rating ranges from 1 (lowest), to20 (highest).The purpose of these ratings is to assess the capability of filters to remove particles, to resist airflow, and to assess the durability of a product.

In general, air filtration systems come in two categories: electrical and mechanical. However, there are many other types of air filtration systems that offer specific functionality as described below.

Flat-Paneled Fiberglass Filter: These filters have a medium level efficiency with a rating between 1 and4. The metal-like robust body protects the filter from break age. These strainers are suitable for catching large airborne elements-not dust, dust mites, and bacteria.

Pleated Filter: Disposable pleated polyester filters can catch small as well as large elements, and because of this functionality, they come with a rating from7 to 13.Thishigh efficiency level makes pleated filters an ideal choice for domestic and commercial use. They are very close to the efficiency level of HEPA filters but are available at cheaper rates.

HEPA HVAC Filter: High-efficiency Particulate Arrestance/Air filters, as stated earlier, are devices that have an efficiency rating between 14 and16. They offer higher airflow resistance and support noiseless operation.

HEPA Filter: These machines offer the best air quality; they can strain the pollutants minutely. As per industry standards, they can remove almost all-to be precise, 99.97 percent-of all elements from the air. These devices have an efficiency rating from17 to 20. Installing a HEPA filter will provide the freshest and most hygienic indoor environment.

Different Types of Industrial Air Filters

In their simplest form, air filters are devices that purify a room or office environment by removing contaminants in the air. Such devices are available for home, commercial, and industrial uses, all having different capacities and features. Sometimes, these machines are sold stand alone, and they also come combined with air conditioning or central HVAC filters.

For manufacturers, it is imperative to follow the pollution control guidelines as prescribed by the government. To achieve these standards, manufacturers must control their carbon dioxide (CO2) emission rates. Most manufacturing processes use coal or oil as fuel, which, when burns, releases a significant amount of harmful gases such as carbon and sulfur. Industrial air filters strain the air or gas coming from exhaust processes, and help an organization to control their carbon and sulfur footprint.

Air filtration devices work based on intelligent techniques of air purification. Following find a description of the most common types of industrial air filters.

Basic Filter - Basic filters only catch and filter the solid particles in airflow.

Thermodynamic Sterilization - These devices use heat up to 200 degrees Celsius to sterilize an air flow. With this technique, about 99 percent organisms, such as bacteria, allergens, molds and mildews, can be eliminated. Since thermodynamic sterilization devices do not catch or remove particulate matter or gaseous elements, these units are typically labeled as air purifiers versus air filters. Thermodynamic sterilization is safe and suitable for homes and offices, where noxious gases are not usually present.

UV Germicidal Technique - Ultraviolet Germicidal Irradiation (UVGI) employs UV rays to remove the contaminants from an exhaust stream. The appliance has a UV lamp and a fan that moves air toward a lamp, which treats the stream. After that, a filter traps and removes the dead bacteria from the air flow.

Polarized-media Electronic Air Cleaners - This technology uses an enhanced electronic medium to remove contaminants from an environment or airstream. These air cleaners fall in the category of both mechanical and electronic filters. The devices convert AC into DC to create a polarized field, in which the particles in the air flow are polarized, and caught by a fiber pad. With these systems, even the thinnest contaminant particles can be captured and removed. Additionally, these processes help chemical plants to create a breathable, odor-free, safe environment.

Photo catalytic Oxidation Filters - PCO filtration is a newer method that, apart from filtering air flow, can also help building management resources to save big on electricity consumption by restricting the unconditioned air from entering the duct and the environment.

Ionizers - The air filters that work on this technology ionize the particles in airflow that are then caught by an electrode, which is negatively charged plate. This is a safe and robust technique for industrial and environmental scenarios.

Ways to Control Industrial Odors and Toxin Emissions

Foul odors are common problem that manufacturing facilities and people in and around these facilities come across. Toxic, suffocating smells are caused by odorants that often surface due to industrial chemical processes. Odorants are often carried by unfiltered air and liquid drained out by manufacturing plants. The reason why the nearby areas of manufacturing plants and chemical refineries have an unbreathable or unpleasant atmosphere is their untreated or inefficient odor control systems. Everything that is being released from an industrial procedure needs to be filtered. Air filters, dry and wet scrubbers, pollution control equipment, and adequate, well-equipped exhaust stream are some of the most effective measures that a manufacturing business can consider to reduce the release of odorants into the atmosphere.

Potential Sources of Odor

Any wastewater, such as sewage and industrial or chemical process can be held responsible for air and water pollution, and to some extent, noise pollution. In addition, here are some probable source of odor-oil refineries, foundries, paper and plastic mills, fertilizer factories, pharmaceutical production units, detergent and soap manufacturing plants, tobacco mills, sugar mill, waste treatment plants, transportation, rubber plants, sewage treatment plants, sewage drains, meat processing facilities, fishing industry, food processing, chemical refineries, and the list goes on.

While these are the primary sources, there are various procedures and practices that generate odorants, causing a serious threat to the environment. These contaminants generate under specific situations, such as microbial decomposition of hydrogen sulfide, mercaptans, and rich nitrogen compounds, like ammonia and skatole. Most of the times, whiff is derived when organic elements are kept in storage that does not have oxygen or a supportive temperature. Many times, when chemicals meet water or process liquids, they create a toxic stink.

Sometimes, the odor comes from a mixture of substances, for example, from waste treatment plants. The intensity of malodor can be assessed by mechanical and chemical measurement methods. Odor type, threshold, intensity, character, and acceptability are the attributes to evaluate the significance of the odor spread over an area.

Ways to Reduce Odor Emissions

Industries and individuals can consider several ways to control the release of odor. Not all the technologies and methods can be listed here; however, a few compelling ones follow.

Odor control systems - There are a variety of odor control systems that manufacturing facilities can choose from to install. These intelligent systems are typically mounted on the exhaust streams and process equipment in order to treat the air and liquid stream right before it is released.

Temperature control systems - As stated earlier, temperature plays a pivotal part in degeneration of organic substance, which causes the release of unpleasant odor. By manipulating substance's temperature, you can keep the odor in control.

Pressure control mechanism - Regulating the air pressure within the storage, in which the biodegradable components and chemicals are, should also help in lowering the level of odorants.

Air exchange - Using suitable ventilation or air exchange for materials, such as dry wood chips, can decrease the production of contaminants and gaseous elements.

Air and wet scrubbing - Air pollution scrubbing is a result-oriented method of controlling the discharge of pollutants and odorants into the atmosphere.
