Breathing Air Filters: The Ultimate FAQ Guide

There is a lot you must know before buying breathing air filters.

These include the design, working principle, application, classification, efficiency, installation process, quality standards, and maintenance, just to mention a few.

All this information is in this guide.

So, if you want to be an expert and learn how to skyrocket your breathing air filtration systems business, read this guide.

What is Breathing Air Filter?

A breathing air filter is a piece of equipment or device which has a porous filter material for removing contaminants.

These contaminants include mold spores, bacteria, solid particles, moisture, oil vapor, and odor from breathing air.

You can fit them in application systems where the provision of quality air is necessary.

These applications include factories, ventilation of houses, and engines.

Breathing air filters

How does a Breathing Air Filter Work?

When contaminated atmospheric or compressed air enters the filter, larger solid particles that cannot be suspended in air hit and stick to them.

This process is called impaction.

The filter removes the medium size particles through interception.

Here, the particles float in the air through a turbulent flow.

The smaller diameter of the filter restrains the particles which have larger diameters.

Also, the filter cleans the remaining small particulate contaminants through diffusion.

Because the particles are tiny, they move randomly, hitting air molecules which slow them down and stick on the filter medium

The air continues to a Coalescing filter, which has filter elements with smaller sieve diameter.

In fact, the filter elements collect moisture and oil droplets when the air passes through the filter.

The droplets are amalgamate into large particles which drain into the filter housing.

This air continues in adsorption filters fitted with activated charcoal.

Oil vapor, lubricants, and odor are removed at this stage through when they bind to the surface of the activated charcoal.

The resulting air will be fresh and free form major contaminants

What is Industrial Air Filter?

This filter removes different types of aerosols, inert particles, and oil vapors in specific areas that produce these contaminants in a plant.

They also provide fresh air for workers at the same time

How long can a Breathing Air Filter Last?

The shelf life of most breathing air filters ranges between two and five years when packed in original containers.

The durability of your filters is affected by different factors.

They include the:

  • Type of application
  • Type of filter element
  • Operating environment conditions
  • Throughput rate
  • Level of air contamination

You should carry out routine checks to determine the conditions of your filters.

This is even critical when the application doesn’t have a differential air pressure indicator.

You can also install a differential pressure indicator that will alert you when the air filters you are using are clogged and require replacement.

Generally, you will replace the air filters every three, six, or twelve months depending on the type of breathing air filter you are using.

Under intense operational conditions, you will replace the filters every month.

How many Types of Breathing Air Filters are there?

There are different types of breathing air filters that remove different kinds of contaminants.

They include:

· Particulate Filters

You can use particulate air filters when you want to get rid of solid contaminants like dust from the breathing air.

These filter elements are meshed and physically trap the solid contaminants as the air passes through the filter medium.

These filters use three different methods while sieving out the solid contaminants.

They include:

Air particulate filter

  • Impaction-This occurs when heavy particulate pollutants that are too heavy to float on the airflow directly hit the filter fibers and get trapped.
  • The interception-This process captures the solid inert materials that float in the air through the turbulent flow of the air stream.

They are filtered out when they pass through filter elements with smaller sieve diameter.

  • Diffusion: This process removes smaller particles. These particles usually have an erratic motion on the fluid, following the principles of the Brownian movement.

The random movement and continuous coalition with air molecules slow the particles down.

The filter media then intercepts and retain the particles.

· Coalescing Filters

Coalescing filter

You can use these filters for cleaning out aerosols, moisture, and oil from the system

They are made of course matt with tiny fibers that can trap and amalgamate small oil and water droplets into large drops.

The large drops then flow down the filter through gravity and collect in the housing bowl.

You can remove the liquid through a drain fitted at the lower parts of the housing.

These filters can also remove particulate contaminants.

These filters will easily trap particles as small as 0.3 to 0.6 microns. Activated Carbon Filters/Adsorbent Filters

Activated carbon air filter

You will require these filters when you want to remove odor and oil vapor from the breathing air.

You should ensure to install activated carbon air filters after particulate and coalescence filters as they cannot remove solid and liquid contaminants from the air.

They adsorb vapor using activated charcoal or chemicals with similar characteristics.

They remove vapor when it bonds with the surface of the adsorbent charcoal.

Activated charcoal has explicitly an extended surface area and a very high affinity for oil vapor.

With time, the surface of charcoal gets saturated and demands replacement.

You can install a particulate filter after an adsorbent filter using charcoal as dust from this material will be carried into the air stream and the system.

How much does a Breathing Air Filter Cost?

The cost of air filters will depend on the type of material used to make the housings and the filter elements.

Price is affected by the kind of operations.

Generally, you will pay more for activated air filters than for pleated or particulate filters.

While you will get car filters for about $1 to $30 per piece, activated carbon filters can cost between $ 200 and $ 300.

The prices of the products will greatly vary depending on the type of product.

You can always visit the website of breathing air filter manufactures to confirm the costs and budget appropriately.

What are the Quality Standards for Breathing Air Filters?

Different countries have different sets of provisions and requirements that have to be met by the breathing air filters for various applications.

Internationally, ISO 12500 series provide for global standardization procedures that should be followed by manufacturers of breathing air filters.

The first part of ISO 12500 gives provisions for testing of coalescence filters performance in the removal of oil aerosols.

Part two of the standard gives procedures on how to quantify the amount of vapor removed by adsorption filters.

Likewise, part three of the ISO 12500 standards give instructions on testing particulate filters performance in the decontamination of solid particles.

The filters will be rated depending on the test results.

What Factors affect the Efficiency of Breathing Air Filter?

The following factors will affect the effectiveness of your breathing air filter:

  • Operational conditions including working temperature, pressure and flow rate
  • The quality of material used in making the housing
  • The type and quality of filter media in the filter elements
  • The grade of the breathing air filter
  • The quality and frequency of servicing and maintenance

What are the Components of Breathing Air Filters?

The components of a breathing air filter vary depending on the application of the breathing air filters.

Standard compressed breathing air filter comprises;

Parts of breathing air filters

  • Housing-This is the part that you use to hold together the contents of the breathing air filter, such as the filter elements.

It also has a bowl that collects liquid contaminants from the elements.

  • Filter Elements-These devices perform the actual cleaning of the air. There are different types of filter elements made from different filter medium for various functions.
  • The Drains-These are located at the bottom part of the housing and allow easy removal of liquids collected in the bowl.

Drains can be automatic or manual.

Automatic drains will release automatically when the liquid in the bowl has reached one-third of its capacity.

  • Differential pressure indicators– These indicators measure pressure drop and purposefully signals when the filter elements require replacement.
  • Inlet and Outlet-They permit the flow of contaminated air into the filter and exit of clean air out of the filter

What Material is Breathing Air Filter Made of?

Material selection for filter housing varies depending on your system application.

Generally, in-line air filters have housing and filter elements, while breathing air filters for the ventilation system have casing and filter elements.

For in-line air filters, you can make the housing from carbon steel, cast aluminum, zinc, iron, or steel (either SS 316 grade or SS 304 grade).

If your application system uses casings, then you can select from casing made from plastics (either from high-quality polystyrene, polyethylene, polyvinyl chloride, or polypropylene).

In the case of filter elements, you can choose the following materials:

Breathing air filter element and housing

· Fiberglass

They are the most widely used type of filter medium.

Generally, you can use them to filter out large particles.

This filter medium has several stocking of layers of fiberglass fibers on top of each other.

The pile is reinforced with a steel frame to hold them together.

· Pleated Filters

This filter medium consists of a thin sheet of cotton, paper, or polyester, folded to form pleats.

They have higher filtration ability compared to fiberglass because of the high airflow resistance they offer.

· Activated Carbon

You can use this filter to clean out of volatile organic compounds such as odor and oil vapor.

Carbon sources are heated in the absence of oxygen at very high temperatures to produce this material.

This process is known as destructive distillation/pyrolysis.

The heating separates pure carbon form other types of carbon.

The carbon is activated through steam heating at 800°C.

This process results in millions of cracks that are about 0.002 microns on the surface of activated carbon.

These cracks provide an extensive surface area for the adsorption of organic compounds.

· Borosilicate Glass Fibers and Plastic (Polypropylene) Fibers.

HEPA Filters

You can use these materials to make a filter medium for HEPA filters.

Usually, you can make the fibers from fine glass threads that do not exceed 1 micron in diameter.

They are then compressed and bound together into a filter mat using acrylic binders.

Air fills up most of the matt due to their microscopic nature.

You can use these filter media to filter particles with up to 0.3-micron diameters, given that their openings are usually tiny, that is, less than 0.5 microns.

How can you Install Breathing Air Filter?

When installing a breathing air filter, you should ensure that you seal all loopholes against unfiltered bypass air.

Follow these steps in installing breathing air filters:

  • Before installation, ensure that you order the correct size of the r systems.
  • Ensure that the filter elements are free from damages, and the sealing on the frame s done well.
  • Take note of the airflow and install it according to the manufacturer’s direction on the frame or housing.
  • Ensure to match the filter arrows with the direction of the system airstream flow.
  • Correctly install the filter fasteners and reinforce the bank of filter frame so that the filters don’t collapse
  • Make sure to have activated carbon filters downstream after the particulate filters and coalescence filters.

Do Breathing Air Filters have a Warranty?

Yes, many manufactures offer warranty for breathing air filters and accompanying accessories for a period ranging from three months to five years.

The warranty will depend on the type, quality, and cost of the air filter. Generally, expensive filters tend to have a more extended period of warranty cover.

However, most manufacturers will not cover the cost of repair for products that spoil from normal wear and tear, misuse, neglect, ignoring instructions, modifications.

What are the Advantages of using Breathing Air Filter?

Here are some of the most outstanding benefits that you are likely to reap from using breathing air filters.

  • You will have access to quality breathing air free from contaminants either at home or work
  • They will remove combustible dust in factories hence reducing the risk of combustion.
  • You will have little risk of inhaling poisonous gases like carbon monoxide when using compressed air applications for breathing.
  • Removal of dust and solid particles will protect the moving parts of your machines from ware and tare.
  • Similarly, other gases and corrosive materials with detrimental effects on the application systems will be filtered out
  • If you are prone to allergies or suffering from asthma, then using air filters will reduce these attacks by filtering out attack causing agents.
  • By using high rated HEPA filters, you will be able to reduce the number of airborne bacteria and mold with potential adverse health effects.

How can you determine the Quality and Effectiveness of Breathing Air Filter?

You can determine the effectiveness of a breathing air filter through dust holding capacity and efficiency as described below:

· Dust Holding Capacity

This test is specifically more critical in determining how durable your filter will last.

This technique relies on measuring the total weight of contaminants the filter retains throughout its operational life cycle.

Air filters that can retain the highest amount of contaminants will give you prolonged and effective services compared to those that hold fewer particles.

· Efficiency

You can conduct a simple efficacy test by measuring the percentage of contaminants that are captured by the filter and those that go through unfiltered.

A filter that allows passage of the least amount of contaminants is considered the most effective.

Efficiency test includes:

  • Dust Spot Test

You will conduct this test if you want to measure how effective your filters can retain fine particles between 0.3 and 0.6 microns.

Feed-in the atmospheric air through the filter and establishing its efficacy in reducing surface stain.

  • Arrestance Test

You will use this test for particulate filters when you want to determine their efficacy in retaining large and heavy particles.

Here, you will pass an artificial powder through the filter and measure the weight of dust captured relative that fed in.

This test is standard for low-efficiency filters.

  • DOP (Dispersed Oil Particulate) Test

You will conduct this test for high efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) filters

Disperse oil aerosols through the filter medium from the upstream flow.

Using a calibrated photometer, measure the amount of particles that pass through the filter downstream or in the outlets.

If the filters are capable of removing up to 99.97% of molecules and particles measuring 0.3 microns, then they are considered ‘true HEPA’ filters.

However, you can still categorize a filter that does not meet these standards but still give good results as ‘near HEPA’ filters

  • MERV (Minimum Efficiency Reporting Value)

This test was founded by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) in 1987.

This method tests the efficiency of HEPA filters’ ability to filter out different sizes of particles ranging from 0.3 to 10 microns.

This test classifies filters into grades ranging from 1 to 16.

Accordingly, the highest categories of filters also correspond higher value of particles captured on each pass.

You will use grades 1 to 4 filters for removing contaminants like carpet and textile fibers and pollen dust that have a diameter greater than 10 microns.

Grades 5 to 8 filter particles whose diameter range between 3 and 10 microns such as mold spores, fabric protectors, etc.

You can use grades one to 12 filters for contaminants like milled flour and auto emission particles that do have between 1 to 3 microns’ diameter.

Grades 13 to 16 filters have the smallest mesh and filter unto 95% of particles that pass through them.

You can use them to filter out particles that have diameters ranging from 0.3 to 1 microns and higher such as bacteria, smoke, and insecticide dust.

How can you determine the Required Quality of Breathing Air?

Modes of filtration

You should periodically examine the breathing air quality to ascertain that your filters are working as expected.

ISO 8573 Series and ISO 7183 series give provision to follow when testing the quality of breathing air.

However, these standards are not legally binding.

Therefore, individual countries also have developed their rules which regulate the quality of air within their territory.

It is therefore empirical that you test whether your controls and filters have been meeting these standards.

You can have your checks as part of risk assessment tests.

Ensure that you carry out tests every three months for low pressure breathing air system.

However, you will have to shorten the time for high-pressure filters.

You can do air quality tests at the time of installation, at 50% of life usage depending on hours under operation.

Any other test will be determined on the intensity of use and should not go beyond three months.

In cases where a mobile air compressor is supplying the breathing air, ensure to carry out air quality test every time you move it.

You can choose an appropriate and more befitting efficient and straightforward test method among the following:

  • On-line gas testers
  • Sample collection for lab analysis off station
  • Color change in tubes

What are the Effects of Contaminated Air?

Contaminated breathing can present health, legal, and financial problems to the employee and the employer.

These include:

  • Inhaling contaminated air can increase your chances of developing complicated illnesses and conditions like asthma, internal chemical burns, and even cancer.
  • Other contaminants like carbon monoxide can cause sudden and fatal results.
  • When you inhale air that contains oil vapor with oil vapor, then you are like to contract pneumonia.
  • Employees working underprovision of poor quality air will always underperform due to loss of morale
  • Underperformance will be accompanied by many off days to seek medical attention from complications arising from poor quality air.
  • Your company is likely to suffer substantial financial losses as a result of lawsuits from sick employees and health and safety regulatory bodies if you fail to provide standard quality breathable air.

What is International Breathing Air Standards?

It is a group of international standards provided by the ISO 8573 series. They relate to the allowable amount of pollutants in the air.

These primary standards principle is to protect human health.

The world health organization has provided standards that should act as a guideline for different countries who may choose to adopt or not to adopt.

ISO 8573 series consists of nine parts.

The first section classifies air quality levels and outlines types of different contaminants.

This section ranks air quality from a class of 0 to 9, with 0 being the most hazardous and nine the least.

The parts 2 to 9 give instructions and detailed procedures to follow to ensure an accurate measure of all contaminants of the breathing air consumed by the end-user.

What Factors determine the Choice of Breathing Air Filter?

Before your place your order, you need to ensure that the breathing air filter you are purchasing will meet your needs.

You should consider the following:

Breathing air filter cartridge

· Your Operation Application

You need to know how you are going to use the air filter.

Do you want filters for a house ventilation system, in-line air filtration in compressed air for scuba diving, or manufacturing plants?

· Operation Condition

You will need to get an air filter that will correctly match the piping systems of your applications.

You should also consider the working pressure, temperatures, and flow rates of your system application.

It is specifically essential because these factors profoundly affect the durability of your breathing air filters.

· Rating of the Air Filter

Rating is more so important when you target to filter out specific contaminants.

Are you interested in protecting sensitive components of your system or provision sweet-smelling breathing air in an area that atmospheric odor is compromised?

Therefore, you will need a highly rated filter for either of the above functions.

· Budget

As with all other aspects, economics is of at most necessity, especially with the type and sensitivity of your operations.

You will have to match the best kind of filter you can get for your system operations with your budget allocation.

Are Breathing Air Filters beneficial to Persons with Respiratory Complications?

Yes, breathing air filters have a lot of impact on people with underlying respiratory conditions such as asthma and allergies.

These filters will remove contaminants from the air free of airborne irritants.

This will provide clean and fresh air that will reduce respiratory attacks that can be caused by unfiltered air.

What are the Limitations of Breathing Air Filters?

There are numerous limitations classified based on filter types and their use.

Some of these limitations include:

  • The efficiency and productive service life of any filter rely on conditions of use.
  • Always follow the manufacturer’s instructions while installing or replacing filter/filter elements.
  • While pressure indicator is vital in signaling when to change the filter elements, you should always carry out a routine inspection to ensure the integrity of the elements
  • You should not use filters that cannot remove toxic elements in atmospheres that present a potential danger to health or human life
  • Always ensure that your spare parts adhere to the requirements of the original manufacturer of the filters
  • Most filters are not suitable for use in the atmosphere with less than 19.5% oxygen content.

Why import Breathing Air Filters from China?

You should consider importing air filters from China because they make quality products at relatively low prices.

Many manufacturers in China have state of the art facilities, and their employees are master designers.

Additionally, the majority of these manufactures are ISO certified, an assurance of premium products.

Additionally, you are always guaranteed competitive prices.

How do you Maintain Breathing Air Filters?

You should always conduct routine maintenance operations to ensure that your breathing air filters are providing a high quality of breathing air.

While servicing the filters, take care to gently remove the used filters to avoid dusting and contamination of the environment.

You should also take care not to inhale the dust.

Using the drains and clean the housing with a piece of cloth soaked in mild soapy water to remove dust and other particles.

For reusable air filter elements, you can soak them in water then thoroughly scrub using a mixture of vinegar and water to help decontaminate the bacteria.

Set the filters to dry out before reinstallation in the system.

In case you are installing new filters, make sure that you match the arrows on the filters to airflow directions in the system.

If your filters are using automatic drains, it is vital to check their integrity.

You should calibrate your monitors and differential pressure gauges every month, or in case you have questionable concerns with your reading.

Can you clean Breathing Air Filters?

Activated carbon air filter

The answer is yes, and no.

There are some filter elements that you can clean while others will be damaged when you try to clean.

Generally, you cannot clean all air filters.

Make sure to follow the instructions and recommendations of the manufacturer on how to clean the air filters.

You can soak the filters in warm soapy water and brush the particles off. You can also use a vacuum cleaner or compressed air for removing dust particles.

You don’t need to wash or vacuum clean carbon filters since they don’t retain any solid particles.

You can just expose this type of filters directly to the sunlight for 2 to 4 hours.

However, even with cleaning, the performance of the air filters will still be below optimum.

It is thus advisable that you acquire new filters if you are working with susceptible operations.
