Poultry House Air Filters & Filtration

EFS /

With rising concerns regarding avian influenza, many poultry producers are now thinking of the ways to filter the air in their poultry houses. However, getting clean air into these farms can be very costly and difficult. Nevertheless, with the complexity of and highly crowded poultry houses, with dust and air borne particles, air filtration has become critically important and a never ending concern for the poultry house owners and producers.

There are the poultry facilities where specially designed filtration systems have been installed in order to prevent external pathogens from entering the space. These completely-closed, filtered-air, positive pressure (FAPP) houses are usually used for carrying out disease research and producing eggs for the vaccine development where it is vital that fresh air entering inside is pathogen free. In a FAPP poultry house, external air is drawn through very powerful fans of high efficiency HEPA filters, capable to remove 99.97 % of the airborne particles with size 0.3 micrometers or larger. The air is pushed into the poultry house then and distributed by using a duct system. The exhaust outlets present in the house are comparatively small, which makes a very high positive pressure inside the house.

It is significant to consider that because HEPA filters are developed to eliminate very tiny particles, they can be quite restrictive to the air flow. As a consequence, the blower fans in a FAPP house utilize substantially higher power per CFM moved than that used in the typical poultry house. It should be kept in mind that all prevention efforts must first focus on proper farm biosecurity measures and practices. Quite simply, it is equipment, people, rodents, and wild birds etc, which are most likely the transmitters of particles. Another critical aspect of the poultry farm is that they are surrounded by fences to keep foreign transmitters of bacteria or germs, such as vehicles at a safe distance. Extreme caution must be taken while installing the filtration system on a poultry house.

The typical ventilation often times won’t be compatible. Heavy-duty ventilation systems are developed to manage the force needed to pull air through the kind of filter material required to eliminate the particles sizes that are of major concern. Air exchanges may be greatly decreased by filter material installation over air inlet openings. Overall, Proper air filtration in a poultry house is quite difficult and costly. Though filtering incoming air might prove a sound investment on certain farms having extremely precious birds (i.e. primary breeding stock), but for most of the producers, efforts should also be first focused around sound biosecurity practices.

High Quality Air Filtration to Combat Pollution & Contamination

Due to the increase of pollution in many parts of the world, urban data centers have been facing increasing mechanical failures. The major underlying cause is poor air quality that essentially needs a high quality air filtration system.

Industrialized regions like New York, Tokyo, Beijing and Los Angeles are the biggest victims of air pollution, which is caused by their industrial manufacturing, traffic congestion and refineries. All these cities have deployed giant data centers having networked computers storing business’s IT systems, machines and equipments. Due to rising air pollution, data centers are having poor air quality, resulting in negative impacts on operations in many ways.

The Corrosive Impact of Contaminant’s

To adequately retain the efficiency of data centers a cooling temperature of 70–75 °F (21–24 °C) should be maintained in order to reduce exposure to contaminants. Corrosion in electronic components is one of the biggest risks to data center functionality.

Contaminants entering the systems through ventilation systems and doorways while people move in and out of the premises are the main cause of corrosion. Among various harmful gases that cause corrosion, the major ones include sulfur dioxide, particulate mate (PM) and hydrogen sulfide. In busy cities like Beijing the emission from cars exhaust, coal power plants and fires usually generate particulate matter, forming a thick haze that pollutes the city.

These contaminants also affect computer circuitry and metal, as well as electricity, follow and eventually result in burn out or blackouts of components, since electricity starts to flow via wrong channel. In addition, air pollution also increases salt concentration in the air, which is the major generator of corrosion. Hence, poor air quality accelerates deterioration rate of electronic components.

How is Air filtration the solution?

If your company has a data center, it is imperative to minimize the impact of poor indoor quality which can be done with the help of a high quality air filtration system.

Filtration systems able to monitor real time are usually the best since they assure optimal functioning of air filtration devices. Proper air filters clean the air entering the data centers and also pressurize it to stop external contaminants from entering the equipment.

Air Filtration for Swine/Pig/Hog Farms

EFS /

Different filters are recommended for a specific farm based on it’s operations. HEPA filters are often recommended due to their 99.97%+ efficiency and ability to catch up to 0.3 micron particle size. The efficiency percentage increases for larger particles and decreases for smaller particles, but as the particle size becomes extremely small, the efficiency actually increases again. 

 As the filter becomes ‘used’, it becomes more efficient, because trapped particles help to filter an even higher percentage of small particles.  Filtration is carried out by three basic means:

 1.Impaction: Bigger particles cannot avoid filter fibers. They enter directly. This is the way these bigger particles (>0.4 um) are trapped in the filter. 

2.Interception: Smaller particles enter within 1 radium of fiber and stick to it. These particles (<0.4µm) are stick there via van der Walls forces. 

3.Diffusion: Brownian motion (turbulence) amplifies the possibility that small particles can be stopped by impaction or interception. 

 Filter Options

 Many manufacturers are concerned with low cost filters. All filters are not equal and present rating systems are not essentially applicable to farming operations. Frame integrity, materials quality etc is more importance to ensure no air bypass. Partial filtration will remain in the market because of cost efficiency. 

 High Temperatures

 By using PRRS virus survivability curve, it might be possible to stop filtration at a certain summer temperature while just taking on least risk of aerosol introduction of the virus. For managing huge air volume through a cool cell in summer ventilation, a filter bank should be nearly 3 times the size of cool cell pad. However, all of this can be very costly. Another application is in farms where the air comes via ceiling inlets year-round. An additional row of inlets might be put in at a quite minimal cost. 

 Challenges 

•How can everything be sealed up? Since the system is based on negative pressure, there is always an issue of minimizing air entrance into the building through the filter. 

•Summer filtration. To fulfill the ventilation requirements of a non-air conditioned barn, about three times the number of filters in the summer is required as in the winter. 

•All doors must be secured. 

•Back-drafting via inactive fans is a problem as fan louvers might stick open and do not give a good seal when closed. 

HEPA filters offered by EFS are passing through real transformation in terms of efficiency and advancement, since it is the requirement for increasing farming operations. High quality air filtration systems are proving to be great contributors towards minimizing virus’ and creating a cleaner environment.

Filters for Isolation Rooms and Gaseous Pollutants

EFS /

For isolation rooms in hospitals, the main goal is to keep airborne infectious diseases such as tuberculosis from entering the atmosphere. To accomplish that, the air from hospital isolation rooms is filtered on the exhaust side as well as on the incoming side, using a sophisticated exhaust fan system on the ceiling where the air has to go through a minimum of two stages: a pre-filter stage and a high efficiency particulate air (HEPA) stage.

Both particulate and gaseous pollutants cannot be removed by a single air filter. Particulate matter is removed by High Efficiency Particulate Air filters (HEPA). The HEPA filter is the most effective filter in removing 99.97% particulates 0.3 micron or larger.

Gaseous pollutants such as sulfur dioxide, carbon monoxide and nitrogen oxides are removed by using activated carbon filters. Carbon filters such as the carbon v4 bank filter which are used in commercial and industrial buildings, are designed to trap smoke, odors, chemicals and gases from the air. Activated Carbon filters are often used in conjunction with a HEPA filters in public commercial settings such as hospitals, museums and airports to remove the larger air particulates.

Low Pressure Drop Air Filters

EFS /

The low-pressure drop is what equates to the amount of electricity it takes to push the air through the filter. The more electricity or power it takes to push the air through the filter, the higher the pressure drop. Energy is very important in regards to filters because the lower the pressure drop, the less amount of power it’s going to take to push the air through the filter. EFS conducts as much research and development as possible in order to get the pressure drop of high efficiency air filters as low as possible while still being able to effectively filter the air.

When selecting low pressure drop air filters as an upgrade to the HVAC system, decision makers should evaluate total system costs. In addition, a life cycle cost analysis should be conducted, which takes into account initial product cost, operating cost (energy consumption), installation cost (labor), and product replacement cost. Higher efficiency filters, while typically more expensive than commonly used low-med efficiency products, are found in most HVAC systems today.

Most HVAC systems are equipped with filters designed to keep equipment components—such as coils, compressors, fans, and ductwork—clean in addition to creating a cleaner air environment. Higher efficiency air filters typically run at a higher airflow pressure drop than lower efficiency filters . Today, however, technology is emerging to increase filtration efficiency while reducing energy consumption. Although higher efficiency filters have higher initial costs, their benefits offset those costs, and pay for themselves within a year or less. Delivering cleaner air throughout the building has the additional benefit of keeping HVAC system components operating at peak energy efficiency, saving still more in energy and maintenance expenses.

HEPA Compliant Filters

EFS /

HEPA filters are deemed compliant based on the way they are tested. They’re tested by third parties; no manufacturer can test their own filters. In the United States, there are specific labs to send filters to that are government regulated, and they have to test the filters under ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) standards. These standards are constantly being worked on based on the medias that are available.

The filters themselves are regulated and tested, not the manufacturer. For HEPA-grade filters have to be tested through ASHRAE standards in addition to a DOP test. It’s the third-party that is regulated by ASHRAE standard, not the manufacturer.

By definition all HEPA filters are individually certified as to conformance with their target efficiency. The data from the testing is provided on a label on every filters stating test airflow, resistance to airflow and penetration (the inverse of efficiency). Originally HEPA filters were tested using dioctylphthalate, a known carcinogen, as prescribed in the original military testing standard authored to address HEPA filter performance.

Today, manufacturers test each HEPA filter according to methodologies as outlined in Recommended Practices (RP) as published by the Institute of Environmental Sciences and Technologies (IEST). Filters are challenged with particles of specific size and the penetration of each filter is so recorded.

The minimum level of HEPA filter performance is an efficiency of 99.97% when tested on particles 0.3 micron in size. As technology has advanced, and the need of ultra clean air in industries such as microelectronics and pharmaceutical has evolved, filters have become available that can provide a performance of 99.999995% efficiency on particles 0.12 micron is size. Because a HEPA manufacturer cannot be responsible for transportation of the filters to the user or handling and installation, many applications require additional in-place testing to ensure the installed integrity of the HEPA filter.

Carbon V-Bank Filter for Air Purification

EFS /

Carbon V-bank filters are most commonly seen in various industrial applications. They can be used in existing HVAC systems, specified for new construction or easily retrofitted. Carbon V-bank filters are helpful to remove different kinds of particles, impurities or bad odors present in the air or its surroundings. These filters bear immense significance especially for air pollution or odor from commercial industries which are higher than normal. Since most of the industries such as chemical, pharmaceutical, construction, fertilizers, use various hazardous raw materials, installation of carbon V-Bank filters is vital for ensuring workers’ health and eco-friendly settings.

Carbon V-bank filters are considered as one of the most absorbent filters as the filtration media has tiny absorbent pores that trap the pollutants when they pass through the filter. The same happens with gaseous odors such as diesel fumes, tobacco smoke, cooking odors, auto exhaust, etc. Odors get trapped in the carbon that is embedded within the filtration media as soon as they enter the filter. Carbon V-bank filters are also highly effective for removing contaminating gases from acetone, paint fumes, gasoline, SOx, NOx, VOCs and Ozone–gasses that are harmful to human health and products.

The carbon V-bank filters are sometimes seen working alongside other filters such as HEPA filters where they work in combination to trap and remove smaller particles or pollutants.
One of the greatest features of carbon V-bank filter is that it doesn’t deposit the air contaminants back in the air, as do some other air filters. This makes them particularly effective in hospital and healthcare settings. As per the latest researches, it has been revealed that carbon V-bank filters are best suitable for removing odors. However, carbon V-bank filters when used in conjunction with other filters like HEPA filters, become highly effective for removing allergens, mold, dust, pet dander, and other contaminants from the air.

Leading The Commercial Filter Industry

EFS /

The #1 commercial filter manufacturer Engineered Filtration Systems (EFS) is one of the most innovative air filter brand in the industry. At EFS, we are determined to always improve and innovate our products to exceed, not only our competition but our own expectations.

With our V-Bank filter for example, when we first came out with this filter it was the highest efficiency on the market and the lowest pressure drop at the time. First and foremost developing break through filtration processes and using the highest quality materials was, and is, our highest priority. However, through the years filter manufacturers have done their due diligence progressing their techniques, but EFS standards soar above market expectations.

Another example of our tenacious pursuit for quality is our reverse pocket filter. They work well as a pre-filter, but other manufactures encountered some difficulty where many systems don’t allow for the depth of a pocket filter. The shortest version pocket filter available is 12 inches deep and in the pre-filter areas of many handlers, there is a limitation in depth which is why the largest pre-filter you find in many standard HVAC air handlers is a 4 inch deep pleat. 

There were many hospitals, for example, that could not upgrade to a standard pocket filter which helps them in regards to filtration and reduces the pressure drop, and last up to 4 or 8 times longer than a standard pleated filter. So we developed a reverse-pocket filter which is installed in a reverse configuration which doesn’t require the depth (12″ or greater) necessary for a standard pocket filter which is just another example of our attention to detail. In addition, the EFS filters have 100% synthetic filter media with non-shedding fibers that resists moisture, chemicals, and bacterial growth. We also have the only bag filter with an extruded aluminum frame which gives the filter enhanced stability, and ultrasonically sealed pocket seams prevent leaks & tears. We consider each facet of the air filtration industry and leave no stone unturned in providing a clean and healthy environment for our customers.

Which industries Use Commercial Air Filters ?

EFS /

Our filters serve numerous applications such as hospitals and health care facilities, bio-tech and electronics manufacturers, gas turbine power plants, clean room facilities, museums, schools and universities, commercial and government buildings, industrial manufacturers and many others. There aren’t many locations that wouldn’t benefit from the application of air filtration because clean air is clean living.

When deciding if it’s absolutely necessary however, there are a few questions you should ask yourself. Is your destination near any industrial polluting plants? Are the products or machinery in your building susceptible to damage from particulates? Is there any children or elderly in your building? Do your customers or tenants complain about a lack of air quality? These are all basic examples of industry traits that would make air filtration imperative.

Where filters are truly relied upon are places such as:

Hospitals: The highest priority for filtration in hospitals should be maintaining clean and healthy air for its patients and staff. Providing an environment using competent air filtration equips patients, staff and visitors with an added degree of protection from airborne microorganisms that can cause infection, disease and even death.

Education: A classroom environment requires quality air filtration. Protection against atmospheric particulate matter which consists of microscopically small solid/liquid particles suspended in the air that can penetrate the respiratory system and damage students lungs over time.

Hospitality industry: most air pollutants comes from foot traffic, open and closing doors, visitors carrying particulates from around the globe and the production of food. These impurities include bacteria, fungus, atmospheric dust etc.
