A HEPA H13 main cartridge, part number 91990118, is also listed for compatible units within this group.

These are different filtration options. Check the extractor manufacturer's approved configuration before selecting or changing filter grades.

ALLCLEAR TA100

A replacement for one ALLCLEAR model should not automatically be assumed to fit another.

The TA100 main F9 filter, part number 91990117, has listed dimensions of 490 × 590 × 85mm.

Match the part number to the machine documentation. Similar-looking filters may have different frames, seals or airflow characteristics.

ALLCLEAR CLEARMASTER

Older extraction equipment can remain useful when compatible replacement components are available.

The collection includes CLEARMASTER main box filters, pre-filters, coarse mats & carbon filters for specified older systems.

Confirm the exact model version before ordering. The designation Old Model is an important compatibility detail, not merely a description of product age.

For the wider range of welding-area controls, browse Welding Safety & Ventilation.

ALLCLEAR Torchmaster

Compact extraction equipment can use specialised filter designs.

The collection includes an ALLCLEAR Torchmaster old-model replacement filter, part number 100281.

Verify the machine version before ordering because older replacement parts may not suit newer configurations.

ALLCLEAR LMD

Bag-style filtration systems require their own compatible replacement components.

The ALLCLEAR LMD bag filter, part number 10034501, is listed as a pack of three.

Follow the extractor manufacturer's handling procedure when removing used filters. Collected welding particulate may contain hazardous substances.

Understand the Different Filter Types

F9 Main Filters

F9 filters are used in specified particulate filtration arrangements.

The appropriate filter must suit the extractor's design, operating conditions & required exposure-control performance.

A classification printed on a cartridge does not establish that every welding hazard is adequately controlled.

HEPA H13 Filters

HEPA H13 describes a high-efficiency particulate filtration classification under defined test conditions.

The collection includes an H13 replacement for compatible ALLCLEAR extraction units.

A higher filtration classification does not guarantee adequate capture at the welding point. Airflow, system condition, inlet position & correct installation remain essential.

For respiratory protection that may be required alongside engineering controls, explore Respiratory Protection & Accessories.

Carbon Filters

Some extraction systems use activated carbon components for specified gas or odour-control applications.

The collection includes an ALLCLEAR MA300/350 optional carbon filter, part number 91990122.

Carbon filtration is not a universal replacement for particulate filtration. Confirm the intended contaminant, filter configuration & manufacturer guidance before use.

Pre-Filters

A pre-filter may capture larger particles before the air reaches another filtration stage.

The CLEARMASTER pre-filter, part number 978004, is listed at 490 × 490 × 50mm for the specified older system.

Replace pre-filters according to the maintenance procedure. A new pre-filter will not necessarily restore performance if another filter stage is heavily loaded.

Coarse Filter Mats

Some systems use replaceable mats as part of staged filtration.

The CLEARMASTER coarse filter mats, part number 978003, are listed in a pack of 10 with dimensions of 490 × 490mm.

Use the specified replacement material rather than substituting general workshop media. An unsuitable mat may affect airflow or filtration performance.

CLEARMASTER Replacement Parts Worth Checking

Main Box Filter

The ALLCLEAR CLEARMASTER main box filter, part number 978005, is listed at 520 × 520 × 250mm.

This replacement is intended for a specified older CLEARMASTER system. Check the equipment documentation before relying on dimensions alone.

Carbon Filter

The CLEARMASTER carbon filter, part number 978006, is listed at 490 × 490 × 20mm.

Its function differs from the main particulate filter. Confirm the complete filtration arrangement before replacing individual stages.

Pre-Filter & Coarse Mats

Maintenance planning becomes easier when every stage has a recorded part number.

Keep a register of the main filter, pre-filter, carbon filter & coarse mats where applicable. This reduces confusion when several technicians service the same equipment.

Five Signs Your Extraction System Needs Attention

1Reduced Capture at the Welding Point

Weak fume capture may indicate a loaded filter, obstructed hose, incorrect inlet position or equipment fault.

Check the complete system using the manufacturer's maintenance procedure. Do not assume a filter replacement will correct every airflow problem.

Filter Indicators Require Action

Some extraction units provide filter-condition or maintenance indicators.

Follow the specific model's instructions for interpreting these signals. Avoid bypassing an indicator simply to continue operating.

Unusual Operating Noise

Changes in sound can indicate mechanical problems or airflow restrictions.

Inspect the equipment according to the manufacturer's troubleshooting guidance. Stop using equipment where continued operation may create an unsafe condition.

Damaged Filter Seals

A cartridge that does not seal correctly may allow air to bypass the intended filter media.

Inspect the relevant seals, frame & retaining components during replacement. Never modify a cartridge to force it into an incompatible housing.

Overdue Maintenance Records

An extractor may appear operational even when scheduled servicing has been missed.

Review the inspection history, replacement dates & required checks. Use the manufacturer's maintenance criteria rather than guessing from appearance.

For broader equipment reliability advice, read Emergency Worksite Breakdown Support.

F9 vs HEPA H13: Which Filter Should You Buy?

A higher filtration grade is not automatically the correct upgrade for every extractor.

Start by checking which filter options the manufacturer approves for the specific machine. Then consider the workplace exposure assessment, intended welding processes & required capture performance.

Different filters can impose different resistance to airflow. A substitution that appears beneficial on paper may be unsuitable for the fan or complete extraction system.

For stainless welding, coated metals or other potentially hazardous applications, assess the entire exposure-control arrangement rather than relying solely on the filter classification.

The correct solution may involve local exhaust ventilation, appropriate respiratory protection, equipment maintenance & workplace exposure monitoring.

Safe Filter Replacement Practices

Isolate the Extractor

Filter replacement should begin only after the machine has been made safe.

Follow the manufacturer's shutdown & isolation instructions. Never open a contaminated housing while the extractor remains in operation.

Protect Against Collected Particulate

Used welding fume filters may contain hazardous metal-containing dust.

Follow the workplace risk assessment for respiratory protection, gloves, containment & disposal. Avoid dry brushing or compressed-air cleaning unless specifically permitted under appropriate controls.

For related protective equipment, explore Work Safety Protections.

Inspect the Housing

A correctly specified filter may still perform poorly if the housing is damaged.

Check contact surfaces, seals & retaining components before installation. Repair identified defects according to the manufacturer's procedure.

Verify the Replacement

Installing a new cartridge does not automatically confirm that the extractor is functioning correctly.

Check the machine using the prescribed maintenance or commissioning procedure. Where required, verify capture performance through suitable testing.

Why Filter Maintenance Is Only Part of Fume Control?

Capture Position Affects Performance

An extraction inlet positioned too far from the welding arc may capture less fume than intended.

Set the inlet according to the manufacturer's instructions. Avoid positioning it where airflow could disturb shielding gas or interfere with the welding operation.

Different Welding Processes Create Different Hazards

MIG, TIG, stick welding & thermal cutting can generate different airborne contaminants.

Parent metal, coatings, filler material & process settings influence exposure conditions.

For equipment-selection context, read How to Choose the Right Welding Machine for Your Fabrication Shop.

Grinding Dust Also Needs Consideration

A workshop may generate airborne particulate from welding, grinding & cutting.

Extraction equipment must be suitable for the intended contaminant & operation. Do not assume a welding fume extractor is approved for every grinding application.

For related equipment, browse Grinder Accessories.

PPE Remains Important

Engineering controls are essential, but some tasks may still require suitable personal protective equipment.

Select PPE according to the workplace risk assessment & applicable requirements.

For related welding protection, explore Welding Helmets & Personal Protective Equipment.

Build a Practical Filter Maintenance Routine

Record Every Extractor Model

Workshops with several extraction units can easily confuse similar-looking cartridges.

Record the model, serial details where relevant, approved filter part numbers & service history. Keep the information accessible to maintenance staff.

Maintain Suitable Replacement Stock

Unexpected filter shortages can interrupt planned welding work.

Use equipment history, supplier availability & manufacturer maintenance criteria to determine which spares should be kept on site.

Store Spare Filters Correctly

Unused filters can be damaged by moisture, crushing or contamination.

Keep replacement components in suitable packaging until installation. Inspect the filter before fitting it.

For practical cleaning guidance, read How to Clean Your Gear Without Ruining It.

Review Support for Older Equipment

Legacy extraction systems may require model-specific components.

Confirm availability before scheduling maintenance. If the original part number is unclear, seek compatibility confirmation rather than modifying an unsuitable filter.

For replacement-part assistance, review Warranty & parts Support.
