What is a fume cabinet?

A fume cabinet is a sealed enclosure which allows hazardous fumes and vapours to be controlled. They can be found in various places but most commonly with laboratories. A fume cabinet has forced ventilation to control the amount of air that passes through the enclosure. Fume cabinets provide local exhaust ventilation. These essentially take contaminated air from a workstation and draw it through an air filter which traps the contaminant, be it particulate or chemical, typically in a carbon or HEPA (High-Efficiency Particulate Air) filter. The air is then exhausted by air ducting to a remote location.

Why you need to test Fume Cabinets

Fume cabinets and control equipment require regular inspection and testing to ensure that your controlled environment continues to meet regulatory requirements.

Fume filter systems are available in a variety of specifications, materials, power capacity, particle size, temperature, and airflow rates. It is essential to ensure that the fume cabinet is correctly specified for the environments it will be used in prior to installation into the laboratory.

Before installing and using a fume cabinet you must check that it complies with the requirements of BS EN 14175-3:2019. This standard is essential as it determines the degree of cleanliness, states how the airflow in a fume cabinet will be maintained, how much contamination will be allowed in the environment and how difficult it should be to remove that contamination.

If registered and certified to BS EN 14175-3:2019 (or equivalent) your fume cabinet will have successfully met these criteria. Get the best value from your cleanrooms with Total Clean Air fume cabinets testing and validation. We offer proven quality performance from our expert team.

Type of Fume Cabinets

Fume cabinets are an integral part of any organisation that requires a clean environment for working with hazardous fluids, powders and particulates. They offer protection to the operator from toxic dusts, vapours and aerosols produced in processes such as laboratory work. They also protect nearby staff from exposure to potentially hazardous materials. There are two major types of fume cabinets. Ducted and Ductless.


Ducted fume cabinets are designed to capture and dispose of hazardous chemical fumes. They effectively vent the air containing the hazardous chemicals from laboratories, and dispose of it into the outside atmosphere, ensuring that the laboratory inside remains safe. These cabinets come in a variety of designs, depending on the type of fume generated.


A Ductless Fume Cabinet provides the same level of containment, while reducing your footprint and increasing your flexibility. These types of cabinets allows you to be free of ducts and their complexities, with no interference with your building’s infrastructure.

Total Clean Air is a specialist fume cabinet distributor supplying a wide range of laboratory fume cabinets to the pharmaceutical and biotechnology industries worldwide. We have over 3 years’ experience in designing, specifying, installing and maintaining laboratory fumes cabinets to meet your exact requirements.

On site DOP testing and Validation of HEPA filters

Dispersed Oil Particulate (DOP) Testing is a test method to ensure the integrity of the HEPA filters. The DOP test is carried out in accordance with BS EN ISO 14644-3. To ensure a high quality of clean air and correct airflow in your fume cabinets, we offer an on-site DOP test at your facility.

The test is carried out by one of our accredited technicians to determine whether the HEPA filter is capturing all the particulates and there are no holes within the filter. We will then provide you with a report indicating when the filter should be replaced. Do you need your HEPA filters tested? Total Clean Air can provide you with all the services you require.

Supply and installation of new Carbon or HEPA filters

Fume cabinets deliver a constant supply of clean air in your work environment. They are designed to ensure maximum protection for tasks requiring controlled amounts of hazardous chemicals or particulates. If you need replacementfume cabinetcarbon or HEPA filters in your cleanroom, laboratory or working environment to protect your worker then please get in touch. At Total Clean Air, we can supply a wide range of Carbon or HEPA filters to protect your workforce.

Integrity testing of HEPA filters

Commercial buildings, laboratories and an array of industrial sectors rely on HEPA filter equipped fume cabinets to protect people from potentially toxic materials.

However, these become ineffective if not maintained properly or if they are damaged as they will allow unfiltered air to leak through the fume cabinet into the workspace. Integrity testing ensures that the filter is working properly.

An integrity test or Dispersed Oil Particulate (DOP) can help in the maintenance and control of your fume cabinets by providing reassurance that the air being cleaned is safe, enabling you to maintain a high level of protection for your workers. An integrity test can also help by allowing early detection of changes in airflow resulting from damage to components such as HEPA filters. At Total Clean Air, our integrity testing of HEPA filters provides you with the proof that your fume cabinet or clean room environment meets the safety standards.

Filter Validation

The filter validation is a procedure to evaluate the integrity of the filters, to show that the filters are capable of removing specific contaminants with retention times greater than or equal to the manufacturer’s specifications.

Total Clean Air provides top of the range filter validation service to the pharmaceutical, biotech, medical devices and cosmetic sectors. Total Clean Air also provides specialist services for fume cabinet validation, servicing and other support services you may require.
