Replacement GVS Filters Page

Dust filters are able to retain airborne particulates and are offered in various constructions, which enhance the filters characteristics with use of various types of filter material with different thickness, porosity and surfaces, to protect against particulates, gases and nuisance odors. Activated carbon cartridge filters contain specific activated carbon, which retain certain gases and vapors by adsorption, while combined filters can remove both gases, vapors and particulates.

There are various types of particulate dust filters which have different filtration efficiency. Depending on which you choose, you can have the most suitable means of protection again environmental pollution conditions. The airborne particles are retained by the filter by means of mechanical and/or electrostatic action.

In the case of gas filters, substances are retained by the chemical -physical action of the activated carbon contained in the filter, able to adsorb and neutralize contaminants. It is assumed that the efficiency of gas and vapor interception on adsorbent material is 100%, at least until the completion of the capacity of the filter material. For gas filters, we refer to ; time to completion or, rather, the period beyond which the filter is saturated and the pollutant begins to pass through the filter. This ‘breakthrough’ time depends on the quantity and quality of the adsorbent material used, on the active area of the cartridge, on its filtration capacity against the pollutant and on environmental concentrations and conditions.

What are NRR Ratings and how are they calculated?

NRR, or Noise Reduction Rating, is a standardized measurement used in the U.S. to indicate how well a hearing protection device—like earplugs or earmuffs—reduces noise exposure. The higher the NRR, the greater the level of sound reduction the product offers, helping to protect workers from hearing loss in noisy environments such as construction, manufacturing, aviation, and heavy equipment operation.

 

NRR is measured in decibels (dB) and is determined through laboratory testing under controlled conditions, as defined by the Environmental Protection Agency (EPA) in the U.S. A product labeled with an NRR of 30 dB, for example, is rated to reduce noise exposure by up to 30 decibels in ideal conditions.

 

However, actual protection in the workplace is usually less than the labeled rating, due to differences in fit, use, and environment. To estimate real-world effectiveness, OSHA recommends a derated value using the formula: Estimated protection = (NRR - 7) ÷ 2 So, a product with an NRR of 30 would provide about 11.5 dB of practical noise reduction.

 

In summary, NRR helps users choose the right level of hearing protection based on the noise levels in their work environment. Selecting the appropriate NRR—and wearing the device correctly—plays a key role in preventing long-term hearing damage.

What NRR level do I need for my environment?

The NRR (Noise Reduction Rating) you need depends on the noise levels in your work environment and the amount of hearing protection required to bring exposure down to safe limits. According to OSHA, the permissible exposure limit (PEL) for noise is 90 dB over an 8-hour shift, while NIOSH recommends a more protective limit of 85 dB.

 

To determine the right NRR, first measure or estimate the ambient noise level at your job site. Then apply the OSHA-recommended formula to estimate real-world protection: Effective noise reduction = (NRR - 7) ÷ 2

 

For example, a product labeled with an NRR of 30 dB will provide about 11.5 dB of actual protection. If your environment is 100 dB, using that hearing protector would reduce exposure to around 88.5 dB, which may still exceed recommended limits.

 

For moderate noise (85–95 dB), a lower NRR (20–25 dB) may be sufficient. For high-noise environments (95–105 dB), choose a protector with a higher NRR (25–30+ dB) or consider double protection (earplugs + earmuffs) if needed. Always match the rating to your environment and task, and ensure proper fit to get the full benefit.

 

In summary, the right NRR depends on your specific exposure level. Aim to reduce noise to below 85 dB where possible, and consult your safety manager or an industrial hygienist to choose the most effective hearing protection for your situation.

What is NFPA 2112 and when is FR clothing required?

NFPA 2112 is a U.S. standard developed by the National Fire Protection Association (NFPA) that specifies the minimum performance requirements for flame-resistant (FR) garments worn by industrial workers. It focuses on protecting wearers from flash fire hazards, which are sudden, intense fires that can ignite clothing and cause serious injury or death in seconds.

 

To comply with NFPA 2112, garments must undergo rigorous testing for flame resistance, heat resistance, and thermal shrinkage. One of the most critical tests measures the mannequin burn injury prediction, requiring that no more than 50% of the body area sustains predicted second-degree or worse burns after a simulated flash fire. This ensures that FR clothing offers proven protection under real-world conditions.

 

FR clothing certified to NFPA 2112 is typically required in industries where flash fires are a known risk, such as oil and gas, chemical processing, refining, and utilities. Employers are responsible for conducting hazard assessments and providing appropriate protective gear where needed.

 

In short, NFPA 2112 ensures that FR garments meet strict safety standards for flash fire protection. If your workplace involves flammable gases, vapors, or dust, FR clothing that meets this standard is not just important—it’s often a regulatory requirement.

What does NFPA 70E-2018 define in terms of arc flash risk?

NFPA 70E–2018 is a standard developed by the National Fire Protection Association that outlines best practices for electrical safety in the workplace, including how to assess and mitigate arc flash risk. An arc flash is a sudden release of energy caused by an electrical fault, capable of producing intense heat, light, pressure, and flying debris in less than a second—posing a serious danger to workers.

 

The standard provides a framework for conducting arc flash risk assessments, which includes identifying potential hazards, determining the likelihood and severity of an arc incident, and implementing protective controls. It also defines Arc Flash Boundary distances, within which workers must wear proper PPE and follow strict safety protocols to prevent injury.

 

One of the key features of NFPA 70E is the categorization of arc flash protective clothing into four PPE Categories (1–4) based on the incident energy level (measured in calories per square centimeter – cal/cm²). These categories help determine what type of flame-resistant (FR) clothing and arc-rated gear workers must wear to remain protected during energized electrical work.

 

In summary, NFPA 70E–2018 is the go-to standard for managing arc flash risk. It provides essential guidance on hazard identification, safe work practices, and PPE selection—helping organizations protect workers from the devastating effects of arc flash incidents.

What are CAT 1-4 FR apparel categories and how do I choose?

CAT 1–4 refers to the four Arc Flash PPE Categories defined by NFPA 70E, which classify flame-resistant (FR) clothing based on the level of arc thermal protection they provide. Each category corresponds to a range of incident energy exposure, measured in calories per square centimeter (cal/cm²)—a unit that indicates the amount of thermal energy a garment can safely handle.

 

CAT 1: Minimum arc rating of 4 cal/cm² (basic FR shirt and pants or coverall)

 

CAT 2: Minimum arc rating of 8 cal/cm² (add arc-rated outerwear or heavier fabrics)

 

CAT 3: Minimum arc rating of 25 cal/cm² (includes multi-layer FR systems or suits)

 

CAT 4: Minimum arc rating of 40 cal/cm² (used for the highest-risk tasks, typically includes arc flash suits with head and face protection)

 

To choose the right category, you must first determine the incident energy level at the task location, which comes from an arc flash risk assessment. Once you know the energy level, you select FR clothing that meets or exceeds that rating. For example, if your worksite has an arc flash energy of 9 cal/cm², you’d need at least CAT 2 protection.

 

In summary, CAT levels guide you in selecting FR clothing that matches the severity of arc flash risk in your work environment. Always choose PPE that meets or exceeds the required arc rating, and ensure it’s worn properly for full-body protection.

What does ASTM F1506 test for in flame-resistant fabrics?

ASTM F1506 is a key performance standard developed by ASTM International that specifies the minimum requirements for flame-resistant (FR) textiles used in electrical arc flash and flash fire environments. It applies to garments worn by workers exposed to electrical hazards, such as electricians, utility workers, and maintenance crews.

 

The standard tests fabrics for several critical safety features, including:

 

Flame resistance – ensuring the fabric will not ignite, continue to burn, or melt after exposure to flame.

 

Arc rating (ATPV or EBT) – measuring the fabric’s ability to resist the thermal energy of an arc flash.

 

Thermal shrinkage – verifying that the fabric maintains its integrity and shape when exposed to high heat.

 

To pass ASTM F1506, the fabric must self-extinguish within 2 seconds, exhibit less than 6 inches of char length, and demonstrate a valid arc thermal performance value (ATPV or EBT). These requirements ensure that garments made from these fabrics provide real-world protection in high-risk electrical environments.

 

In summary, ASTM F1506 confirms that FR clothing has been tested for durability, flame resistance, and arc flash protection. If your work involves electrical hazards, clothing labeled with ASTM F1506 compliance is essential for staying safe and meeting regulatory requirements.

What is ASTM F2733 and how is it used in flash fire environments?

ASTM F2733 is a performance standard developed by ASTM International that sets the requirements for flame-resistant rainwear used in environments where workers may be exposed to flash fires. It is specifically designed for garments made from waterproof materials, ensuring that protection from fire does not come at the cost of protection from the elements.

 

The standard tests garments for several key factors:

 

Flame resistance – the fabric must self-extinguish quickly and not melt or drip.

 

Thermal shrinkage – materials must retain their shape and coverage after heat exposure.

 

Flash fire simulation – garments are subjected to a 3-second flash fire, and body burn prediction is measured using thermal mannequins.

 

ASTM F2733 is commonly required in oil and gas, petrochemical, and refinery settings, where workers are exposed to both flammable atmospheres and outdoor weather conditions. The garments that meet this standard provide a combination of flash fire protection and rain protection, making them ideal for wet, hazardous environments.

 

In short, ASTM F2733 ensures that flame-resistant rainwear performs reliably under both fire and environmental stress, helping keep workers safe in high-risk, outdoor operations. Look for this certification when waterproof FR gear is required.

What does ASTM F955 cover for protective clothing arc tests?

ASTM F955 is a testing standard that evaluates how well protective clothing materials resist heat and damage when exposed to electric arcs, particularly in situations involving molten metal splashes. It is especially important for assessing multi-layer protective garments used in foundries, welding, and electrical utilities, where both arc flash and molten exposure are potential hazards.

 

The test simulates a realistic arc flash scenario by exposing a fabric sample—often layered over a thermal sensor or mannequin—to a high-energy electrical arc. It then measures the temperature rise on the sensor, evidence of ignition, melting, dripping, or sticking of molten metal to the fabric.

 

ASTM F955 is used to determine if the clothing meets safety thresholds for preventing second-degree burns and minimizing injuries caused by heat and molten metal. It helps safety managers verify whether a garment provides enough protection for workers who face combined risks, especially when working near live electrical systems or in metal-handling environments.

 

In summary, ASTM F955 helps confirm that protective garments can endure arc exposure and resist molten metal damage, ensuring higher safety standards for workers in some of the most extreme industrial environments.

What is ASTM F1891 and when is it used in arc flash rainwear?

ASTM F1891 is a performance standard for arc-rated flame-resistant rainwear, designed to ensure that protective garments can withstand both electrical arc hazards and wet weather conditions. It is essential for workers in utilities, electrical maintenance, and power generation, where exposure to both rain and arc flash is a real concern.

 

The standard tests rainwear materials for several key performance factors:

 

Arc thermal performance (ATPV or EBT) – measuring how much thermal energy the fabric can withstand before causing second-degree burns.

 

Flame resistance – ensuring the garment won’t ignite, melt, or continue to burn after arc exposure.

 

Water resistance – verifying that the garment remains waterproof while maintaining its arc-rated protection.

 

Garments certified to ASTM F1891 provide a minimum arc rating of 5 cal/cm² and must pass a simulated arc flash test while retaining their waterproof integrity. This makes them suitable for fieldwork in wet, energized environments, where typical FR garments alone may not offer adequate protection.

 

In summary, ASTM F1891 ensures that arc-rated rainwear performs reliably under both electrical and environmental stress, offering vital protection for outdoor workers facing the dual hazards of rain and arc flash.

What does EN ISO 11611 cover for welding and heat exposure?

EN ISO 11611 is an international standard that sets the minimum requirements for protective clothing worn during welding and related processes. It ensures that garments provide protection against brief contact with flame, radiant heat, molten metal splashes, and electrical contact from welding electrodes, helping reduce the risk of burns and injuries.

 

The standard applies to coveralls, jackets, trousers, and hoods designed for use in manual metal arc welding, TIG and MIG welding, plasma cutting, and grinding. Garments are tested for flame spread, tensile strength, tear resistance, seam strength, and protection against small splashes of molten metal.

 

EN ISO 11611 is divided into two classes:

 

Class 1: For lower-risk welding techniques with fewer sparks and heat.

 

Class 2: For higher-risk processes involving more splatter and greater exposure to radiant heat.

 

In summary, EN ISO 11611 ensures welding garments meet rigorous standards for flame and heat protection, allowing workers to perform welding and hot work safely. Always choose garments certified to the correct class based on your welding method and risk level.

What is the difference between 1/2 masks and PAPR respirators?

The main difference between half-face masks (1/2 masks) and PAPRs (Powered Air-Purifying Respirators) lies in how they deliver filtered air and the level of protection and comfort they provide. A 1/2 mask respirator is a tight-fitting facepiece that covers the nose and mouth and relies on the wearer’s lung power to pull air through attached filters or cartridges. They are lightweight, reusable, and commonly used in environments with dust, fumes, or gases—such as painting, welding, or maintenance work.

 

In contrast, a PAPR uses a battery-powered blower to pull air through filters and deliver it to the user’s facepiece, hood, or helmet. Because the air is actively supplied, PAPRs offer greater airflow, reduced breathing resistance, and higher levels of protection, especially for users working long shifts or in hot, physically demanding environments. They are ideal for settings such as healthcare, pharmaceuticals, hazardous waste handling, and environments with low oxygen or high contaminant concentrations.

 

PAPRs generally offer a higher Assigned Protection Factor (APF) than half masks. For example, a typical 1/2 mask has an APF of 10, while a PAPR with a loose-fitting hood can offer an APF of 25, and tight-fitting PAPR facepieces can go up to 1,000. However, PAPRs are bulkier, more expensive, and require battery maintenance and regular cleaning.

 

In summary, 1/2 masks are simpler, more portable options for moderate protection, while PAPRs provide greater comfort and protection for high-risk or extended-use situations. The right choice depends on your environment, exposure risk, and user needs.

What type of respirator is best for chemical protection?

The best respirator for chemical protection depends on the type, concentration, and form of the chemical hazard—whether it's a gas, vapor, mist, or aerosol. In most cases, air-purifying respirators (APRs) with chemical cartridges or filters are recommended. These include half-face or full-face elastomeric respirators equipped with cartridges designed to neutralize specific chemicals (e.g., organic vapors, acid gases, ammonia).

 

For more comprehensive protection—especially in high-exposure or unknown environments—a Powered Air-Purifying Respirator (PAPR) or a Supplied-Air Respirator (SAR) may be necessary. PAPRs provide easier breathing and increased comfort, while SARs deliver clean air from a remote source, making them ideal for toxic or oxygen-deficient atmospheres.

 

Full-face respirators are often preferred over half masks for chemical protection because they also shield the eyes and face from irritation or splashes. Many chemical-specific cartridges are color-coded (e.g., black for organic vapors, yellow for acid gases), and selection should always be based on a hazard assessment and the Safety Data Sheet (SDS) of the chemical involved.

 

In summary, for chemical protection, choose a respirator that matches the specific chemical exposure—typically a full-face APR with the appropriate cartridge, or a PAPR or SAR for higher-risk environments. Always follow regulatory guidance and consult a safety professional when selecting chemical PPE.

When should I choose a PAPR over a cartridge mask?

You should choose a PAPR (Powered Air-Purifying Respirator) over a cartridge-style mask—such as a half-face or full-face elastomeric respirator—when the work environment demands higher protection, extended wear time, or increased comfort.

 

PAPRs use a battery-powered blower to pull air through filters and deliver it to the user, reducing the breathing effort and providing a steady flow of clean air. PAPRs are ideal in situations where workers are exposed to high concentrations of airborne contaminants, or when the assigned protection factor (APF) required exceeds what cartridge masks can offer. For example, while a half-face respirator has an APF of 10, PAPRs can provide APFs of 25 to 1,000, depending on the configuration. This makes them suitable for healthcare, chemical handling, hazardous waste operations, and confined spaces.

 

They are also a better option when workers need to wear respiratory protection for long shifts, in hot environments, or if they have health conditions like asthma or reduced lung function. The positive airflow in a PAPR makes breathing easier and reduces fatigue over time. Additionally, some PAPR systems are loose-fitting, which makes them more accommodating for users with facial hair or glasses.

 

In summary, choose a PAPR when your work requires high protection, extended wear, or increased comfort, especially in challenging or high-risk environments. While more expensive and bulkier than cartridge masks, PAPRs provide superior respiratory protection and user comfort where it counts most.

What is the difference between M4 and M5 Ariat pants?

The difference between M4 and M5 Ariat pants comes down to fit, rise, and leg style, giving wearers options based on personal preference and comfort. Both styles are part of Ariat’s workwear and western wear collections, designed for durability, function, and long-lasting comfort in demanding environments.

 

M4 pants feature a low-rise waist with a relaxed fit through the hip and thigh, and a boot-cut leg opening. This style offers a more generous cut, making them ideal for those who prefer a roomier feel or need added mobility for bending, lifting, or riding.

 

M5 pants have a slightly higher rise and a slimmer fit through the thigh and seat, also with a boot-cut leg. They offer a more modern, streamlined appearance while still providing flexibility and toughness for active work or riding tasks.

 

In short, choose M4 for a looser, more relaxed fit, and M5 if you prefer a closer-fitting, more tailored look. Both deliver Ariat’s signature durability, but the best choice depends on your comfort needs and style preference.

What are the pros and cons of 1/2 masks vs PAPR respirators?

1/2 masks (half-face respirators) and PAPRs (Powered Air-Purifying Respirators) both offer protection against airborne hazards, but they differ significantly in design, protection level, and comfort. Choosing between them depends on the work environment, duration of use, and specific hazards.

 

1/2 masks are compact, lightweight, and cost-effective. They rely on the wearer’s lung power to draw air through filters or cartridges and are suitable for tasks involving dust, fumes, and light chemical exposure. However, they can become uncomfortable during long shifts, especially in hot or physically demanding environments, and require a tight facial seal—which may be compromised by facial hair or eyewear.

 

PAPRs, on the other hand, use a battery-powered blower to actively deliver filtered air to the wearer’s facepiece or hood. This makes them much more comfortable for extended wear, reduces breathing resistance, and offers higher levels of protection (APF of 25 to 1,000 depending on the system). The downside is that PAPRs are bulkier, more expensive, and require battery maintenance and regular cleaning.

 

In summary, 1/2 masks are ideal for short-term use in low-to-moderate risk environments, while PAPRs are better suited for high-risk or long-duration tasks where comfort, airflow, and maximum protection are critical. The right choice depends on your job’s specific hazards and working conditions.

What is the difference between Type I and Type II hard hats?

The primary difference between Type I and Type II hard hats lies in the direction of impact protection they are designed to provide. This classification is defined by both ANSI Z89.1 (U.S.) and CSA Z94.1 (Canada) standards, which help employers choose appropriate head protection based on workplace hazards.

 

Type I hard hats are designed to protect against impacts to the top of the head only—such as falling tools or debris. They are commonly used in traditional construction and industrial settings where the main risk comes from overhead hazards.

 

Type II hard hats, on the other hand, offer protection against both top and lateral (side) impacts. They have additional padding and structural features to absorb blows from the sides and front or back of the helmet. This makes them suitable for work environments where the risk of being struck from various angles is higher, such as confined spaces, utility work, or areas with moving equipment.

 

In summary, Type I hard hats protect from overhead impact, while Type II hard hats offer all-around protection, including side impacts. Choosing the right type ensures that workers have the appropriate level of safety based on the hazards present in their specific work environment.

What glove cut level do I need for my industry?

The cut level you need depends on the type of work and the sharp hazards present in your industry. Glove cut resistance is rated using the ANSI/ISEA 105 standard, which assigns levels from A1 to A9, with A1 offering the lowest protection and A9 the highest. These levels reflect the amount of force (in grams) required to cut through the glove material with a sharp blade.

 

For light-duty tasks like general assembly, maintenance, or warehouse work, a glove rated A1 to A3 is typically sufficient. These gloves provide basic protection against light cuts from tools, packaging, or materials handling. Industries like automotive or light manufacturing often fall into this category.

 

If you work with sharp materials such as glass, sheet metal, or wire—common in construction, HVAC, electrical, or metal fabrication—you’ll likely need a glove rated A4 to A6. For extreme hazards, such as heavy-duty metal stamping, high-risk cut exposure, or working around blades, A7 to A9 gloves are recommended.

 

In summary, selecting the right glove cut level involves matching the hazard severity to the level of protection. Always conduct a hazard assessment of your tasks, and when in doubt, choose a higher cut level to ensure worker safety without compromising dexterity and comfort.

Which FR category should I choose for electrical work?

The appropriate Flame-Resistant (FR) category for electrical work depends on the level of arc flash hazard present in your environment. These categories, defined by NFPA 70E, are referred to as Arc Flash PPE Categories (CAT 1–4) and are based on the incident energy level—measured in calories per square centimeter (cal/cm²)—that workers could be exposed to during an arc flash event.

 

CAT 1 (minimum 4 cal/cm²): Basic protection for low-risk electrical tasks such as switching low-voltage panels or general maintenance.

 

CAT 2 (minimum 8 cal/cm²): Suitable for more common electrical tasks like panel work, circuit testing, and breaker switching.

 

CAT 3 (minimum 25 cal/cm²) and CAT 4 (minimum 40 cal/cm²): Designed for high-risk work involving larger electrical equipment or high-voltage systems, where incident energy is much higher.

 

To determine which category you need, your employer must perform an arc flash risk assessment that calculates the incident energy levels at different work zones. Based on that, you can select FR garments and gear with an arc rating (ATPV or EBT) equal to or greater than the expected exposure.

 

In summary, the FR category for electrical work should match the calculated arc flash risk in your environment. Always wear PPE that meets or exceeds the required CAT level, including FR clothing, face protection, gloves, and hearing protection as specified by NFPA 70E and your company’s safety protocols.

What is the best glove for chemical abrasion and puncture?

The best glove for protection against chemical exposure, abrasion, and puncture is one that’s specifically tested and rated for all three hazards. Since no single glove material protects against all risks equally, the ideal choice often combines chemical-resistant materials (like nitrile, neoprene, or butyl rubber) with mechanical strength features such as reinforced palms or multi-layer construction.

 

For chemical resistance, look for gloves that comply with EN ISO 374 or ASTM standards and are labeled for the specific chemicals you're handling. Nitrile gloves offer good resistance to oils, fuels, and many solvents, while butyl rubber is better for ketones and esters. Manufacturers often provide chemical compatibility charts to help guide selection.

 

For abrasion and puncture resistance, refer to the ANSI/ISEA 105 and EN 388 ratings. Choose gloves with an abrasion resistance level of 4–6 and puncture resistance level of 3 or higher. Some chemical-resistant gloves now include cut- and puncture-resistant liners to offer multi-hazard protection without sacrificing flexibility.

 

In summary, the best glove is one that matches the specific chemicals and mechanical hazards of your task. Always perform a hazard assessment and select gloves that are certified for chemical resistance and rated for mechanical durability to ensure safe, long-lasting protection.
