Airborne Particle Count Testing Service for Cleanrooms, Server Rooms and Controlled Areas

Airborne contamination is not always visible.

A cleanroom may look spotless while containing an unacceptable concentration of fine particles. A server room may appear well maintained while dust continues to enter through cable openings, outdoor-air intakes, doors or inadequately filtered ventilation systems.

Visual inspection alone cannot establish whether a controlled environment is performing as intended.

Perfect Pollucon LLP provides airborne particle count testing services for cleanrooms, clean zones, laboratories, server rooms, data centres and other dust-sensitive controlled environments across Mumbai, Thane, Navi Mumbai, Pune, Maharashtra and other serviceable locations.

Our particle-counting services can support:

• cleanroom particle count testing;
• non-viable particle monitoring;
• server-room and data-centre cleanliness assessments;
• post-cleaning particle verification;
• particle mapping;
• contamination investigations;
• routine environmental monitoring; and
• classification-related particle measurements.

Backed by more than 25 years of environmental-monitoring and industrial pollution-control experience, our approach goes beyond recording a number from an instrument.

We consider:

• why the test is being conducted;
• what condition exists during testing;
• where samples should be collected;
• which particle sizes are relevant;
• how much air should be sampled;
• what acceptance criteria apply;
• what may be causing an elevated result; and
• whether the report can be defended during an audit or technical review.

A particle count becomes meaningful only when the location, room condition, sample volume, particle-size channel and acceptance criteria are clearly defined.

Airborne Particle Count Testing Services Offered by Perfect Pollucon

Cleanroom Particle Count Testing

Airborne particle counting is a fundamental method for assessing air cleanliness in cleanrooms and clean zones.

Perfect Pollucon supports cleanroom particle-count measurements under defined conditions such as:

• as-built;
• at-rest;
• operational;
• post-cleaning;
• post-maintenance; and
• post-corrective-action conditions.

Depending on the agreed scope, the service may include:

• room-area and layout review;
• sampling-location planning;
• particle measurements at selected size channels;
• sample-volume and duration documentation;
• location-wise result evaluation;
• comparison with agreed ISO or customer limits;
• testing-condition observations; and
• technical reporting.

Formal ISO classification requires more than a few spot readings. The intended ISO Class, particle sizes, room area, occupancy state, minimum sample volume, number of locations, instrument suitability and reporting method must be reviewed before the scope is finalised.

Non-Viable Particle Count Testing and Monitoring

Non-viable particle monitoring measures airborne particles without determining whether those particles are biologically viable.

It may be used for:

• routine cleanroom environmental monitoring;
• periodic particle-count trending;
• comparison with internal alert and action limits;
• investigation of abnormal increases;
• assessment before an audit;
• verification after cleaning or maintenance; and
• evaluation of corrective-action effectiveness.

A non-viable particle counter detects particles according to size. It does not determine whether a particle is:

• a bacterium;
• a fungal spore;
• a skin fragment;
• a fibre;
• product material;
• ordinary dust; or
• another substance.

Where viable microbial contamination is relevant, separate microbiological monitoring is required.

Server-Room Particle Count Testing

Server rooms may not be formal cleanrooms, but airborne dust can still affect sensitive electronic equipment and cooling systems.

Particles can enter through:

• frequently opened doors;
• unsealed cable penetrations;
• outdoor-air intakes;
• ceiling voids;
• raised-floor spaces;
• nearby construction;
• cardboard and packaging materials;
• maintenance activities;
• ineffective filters; and
• poorly sealed service entries.

Over time, contamination may accumulate on:

• cooling components;
• fans;
• printed circuit boards;
• connectors;
• sensors;
• power equipment; and
• equipment ventilation pathways.

A server-room particle count assessment can help:

• establish baseline conditions;
• compare different room locations;
• assess dust ingress;
• investigate visibly dusty areas;
• compare supply-air and room conditions;
• evaluate cleaning effectiveness;
• identify elevated counts near doors or cable openings;
• compare conditions before and after corrective action; and
• support periodic preventive monitoring.

Where an ISO Class, equipment-manufacturer limit or other acceptance criterion has been specified, Perfect Pollucon reviews the requirement before testing. A universal cleanroom limit should not automatically be applied to every server room.

Learn more: Server Room Particle Count Testing

Data-Centre Particle Count Testing

Data centres contain sensitive electronic systems that depend on controlled temperature, humidity, cooling and cleanliness conditions.

Particle-count measurements may be conducted in:

• data halls;
• hot aisles;
• cold aisles;
• rack air-intake zones;
• equipment exhaust areas;
• supply-air paths;
• return-air paths;
• raised-floor areas;
• fresh-air entry locations;
• cable-entry points;
• UPS rooms; and
• supporting electrical rooms, subject to site-safety requirements.

A data-centre particle assessment may support:

• baseline cleanliness surveys;
• post-construction assessments;
• dust-ingress investigations;
• before-and-after cleaning comparisons;
• evaluation following HVAC maintenance;
• comparison between data halls;
• identification of high-particle locations; and
• development of a periodic monitoring programme.

Acceptance criteria should be agreed using the facility design, customer specifications, equipment-manufacturer recommendations, applicable guidance, historical results or an approved internal standard.

Post-Cleaning Particle Count Verification

Cleaning may improve the visible appearance of a room without adequately reducing fine airborne particles.

Perfect Pollucon can conduct particle-count measurements:

• before cleaning;
• immediately after an agreed recovery period;
• after deep cleaning;
• after post-construction cleaning;
• after HVAC maintenance;
• after filter replacement;
• after room sealing work; or
• after implementation of corrective actions.

Before-and-after measurements can help determine whether particle concentrations reduced at the selected locations and particle-size channels.

This service should be described as post-cleaning airborne particle verification rather than complete cleaning validation. Pharmaceutical cleaning validation may involve product residues, chemical contaminants, surfaces and microbiological parameters that airborne particle counting does not assess.

Learn more: Post-Cleaning Particle Count Verification

Particle Mapping and Contamination Investigation

One unexplained reading may not represent the condition of the entire room.

Particle concentrations can vary near:

• entrances;
• air-supply outlets;
• return-air points;
• operator workstations;
• equipment;
• cable openings;
• material-transfer points;
• process activities; and
• suspected contamination pathways.

A particle-mapping survey involves measurements at multiple selected locations to identify:

• high-particle areas;
• differences between room zones;
• possible dust-entry pathways;
• differences between supply air and room air;
• effects of door opening or personnel activity;
• possible housekeeping concerns;
• possible filtration concerns; and
• locations requiring further investigation.

Particle mapping can indicate where a problem may be occurring. It cannot independently determine the exact chemical or biological identity of the particles.

Facilities Where Particle Count Testing May Be Used

Pharmaceutical and Medical-Device Facilities

Particle-count testing may support controlled manufacturing areas, cleanrooms, packing areas, support rooms and other environments where airborne contamination can affect product quality.

The applicable scope may be:

• classification-related measurements;
• routine non-viable monitoring;
• investigation of abnormal results;
• post-maintenance verification; or
• pre-audit assessment.

Particle counting alone should not be described as complete pharmaceutical cleanroom qualification.

Electronics and Precision Manufacturing

Fine particles can affect:

• sensitive components;
• optical surfaces;
• assembly quality;
• precision instruments;
• coatings;
• electronic contacts; and
• product reliability.

Particle-count measurements may be used in electronics assembly areas, precision engineering rooms, optical-component facilities, battery-component manufacturing and other contamination-sensitive processes.

Laboratories and Instrument Rooms

Airborne particle monitoring may support:

• calibration laboratories;
• weighing rooms;
• research laboratories;
• precision-measurement areas;
• optical laboratories;
• instrument rooms;
• laser-equipment rooms; and
• other dust-sensitive spaces.

The testing objective and acceptance basis should be agreed before sampling.

Controlled Packaging and Production Areas

Particle counting may be used to:

• create baseline data;
• compare production and non-production conditions;
• investigate dust generation;
• assess material-transfer practices;
• verify cleaning improvements; and
• support internal environmental-monitoring programmes.

Server Rooms and Data Centres

Particle testing can support dust-ingress assessment, environmental baselining, cleaning verification and periodic monitoring around sensitive IT and cooling equipment.

What Is Airborne Particle Count Testing?

Airborne particle count testing measures the number of particles present within a defined volume of air.

A laser-based particle counter draws air through a controlled sampling system. Particles passing through the instrument interact with a light source, and the resulting scattered light is used to count and categorise particles according to size.

Results may be expressed as:

• raw particles counted during the sample;
• particles per litre;
• particles per cubic foot;
• particles per cubic metre;
• cumulative particle concentration; or
• differential particle concentration.

Cumulative Particle Count

A cumulative reading includes all particles equal to or larger than the selected threshold.

For example, a cumulative reading at ≥0.5 µm includes particles detected at 0.5 µm and larger available channels.

Differential Particle Count

A differential reading represents particles falling between adjoining particle-size channels.

The selected counting mode must be recorded because a differential result should not be directly compared with a cumulative acceptance limit.

Our Particle-Counting Capability

Perfect Pollucon uses the PCE-PCO 1 handheld laser particle counter.

The instrument provides the following particle-size channels:

The PCE-PCO 1 operates at a nominal flow rate of 2.83 litres per minute, equivalent to 0.1 cubic foot per minute. It supports cumulative, differential and concentration modes and also records air temperature, relative humidity and dew point.

Important Instrument-Scope Note

The instrument does not provide direct 0.1 µm or 0.2 µm particle-size channels.

Perfect Pollucon therefore does not claim measurements at those thresholds using this device.

The availability of a particle-size channel alone does not prove that an instrument is suitable for every classification or validation assignment. The following must also be reviewed:

• calibration status;
• counting efficiency;
• flow accuracy;
• required sample volume;
• expected particle concentration;
• applicable class;
• room area;
• occupancy condition; and
• reporting requirements.

Particle Count Is Not the Same as PM2.5 or PM10

Particle count and particulate-matter mass concentration are related, but they are not interchangeable measurements.

Air-quality monitoring commonly reports:

• PM2.5 in µg/m³;
• PM10 in µg/m³; or
• suspended particulate matter in µg/m³.

The PCE-PCO 1 reports the number of particles detected within specified size channels.

A direct and universally valid conversion from particle count to µg/m³ is not possible without assumptions about:

• particle density;
• particle shape;
• actual particle diameter;
• particle-size distribution;
• chemical composition;
• optical properties; and
• instrument response.

Two rooms may have similar particle counts but different particle mass. Two rooms may also have similar particle mass while containing very different numbers of fine particles.

Where PM2.5 or PM10 mass concentration is required for indoor-air, occupational or regulatory purposes, a separate suitable measurement method should be used.

Cleanroom Classification and Routine Monitoring Are Different

Cleanroom Classification

Cleanroom classification determines whether a cleanroom or clean zone meets a specified class under a defined occupancy state and at specified particle sizes.

ISO 14644-1 addresses classification of air cleanliness by airborne particle concentration. It considers cumulative particle populations based on lower-threshold sizes between 0.1 µm and 5 µm.

A classification-related scope must consider:

• room area;
• required class;
• particle-size thresholds;
• number of sampling locations;
• location selection;
• occupancy state;
• minimum sample volume;
• sampling duration;
• instrument flow rate;
• calibration;
• calculations; and
• reporting method.

Routine Particle Monitoring

Routine monitoring provides ongoing evidence that environmental performance remains under control.

ISO 14644-2 specifies minimum requirements for a monitoring plan related to air cleanliness by particle concentration.

A monitoring programme may include:

• fixed critical locations;
• rotating locations;
• defined frequencies;
• alert levels;
• action levels;
• trend analysis;
• investigation requirements;
• corrective actions; and
• periodic programme review.

Classification is a formal assessment under defined test conditions. Monitoring is the continuing evidence that control is being maintained.

Learn more: Cleanroom Classification vs Routine Particle Monitoring

As-Built, At-Rest and Operational Conditions

Particle-count results can change significantly according to the condition of the room during testing.

As-Built

The cleanroom installation is complete and its services are functioning, but production equipment, materials and personnel may not yet be present.

At-Rest

The room is complete and equipment is installed and operating in an agreed condition, but normal production personnel are not present.

Operational

The room is functioning in its intended operating mode with the defined personnel, equipment and activities present.

Operational results may be influenced by:

• operator movement;
• garments;
• material transfer;
• door opening;
• production activity;
• cleaning;
• equipment operation; and
• process-generated particles.

The agreed occupancy condition should be recorded in the field notes and report. A result without this context can be misleading.

Learn more: As-Built vs At-Rest vs Operational Cleanroom Testing

Standards and Technical References

Depending on the assignment, particle-count testing may refer to:

• ISO 14644-1 for classification of air cleanliness by particle concentration;
• ISO 14644-2 for monitoring-plan requirements;
• ISO 21501-4 for calibration and verification of light-scattering airborne particle counters;
• customer specifications;
• equipment-manufacturer recommendations;
• approved facility procedures; and
• sector-specific requirements.

ISO 21501-4 describes calibration and verification methods for light-scattering airborne particle counters used to measure particle-size distribution and particle-number concentration in air.

Formal classification scope is confirmed only after reviewing the required class, particle sizes, room area, occupancy state, sampling locations, sample volume, instrument suitability and applicable standard.

The applicable copyrighted standards must be purchased and followed where formal conformity or classification is required.

• occupancy;
• equipment operation;
• production activity;
• recent cleaning;
• ongoing maintenance;
• nearby construction;
• visible dust;
• temperature;
• relative humidity; and
• abnormal events.

5. Conducting Measurements

Depending on the agreed scope, the test may record:

• cumulative particle counts;
• differential particle counts;
• particle-size-wise concentration;
• location identification;
• sample duration;
• sample volume;
• temperature;
• relative humidity;
• dew point;
• test time; and
• photographs.

The instrument’s flow rate must be considered while determining the sampling duration required to collect the necessary volume.

6. Reviewing the Results

• ISO particle limits;
• customer specifications;
• facility procedures;
• equipment recommendations;
• historical baseline data;
• internal alert and action limits; or
• comparative location-wise performance.

Where no defensible acceptance criterion exists, the results are presented as a baseline, comparison or investigation finding rather than an unsupported pass/fail conclusion.

7. Preparing the Technical Report

The final report is prepared according to the agreed scope and reviewed before issue.

What the Client Receives

A typical Perfect Pollucon particle-count testing report may include:

• client and facility details;
• testing objective;
• test date;
• room identification;
• room dimensions or area;
• occupancy or operating condition;
• instrument make, model and serial number;
• calibration reference;
• sampling plan;
• sampling locations;
• sample duration;
• sample volume;
• particle-size-wise results;
• reporting units;
• temperature and relative humidity, where included;
• applicable acceptance criteria;
• location-wise pass/fail status, where justified;
• field observations;
• photographs, where agreed;
• limitations;
• recommendations; and
• authorised report details.

Our aim is to provide more than one unexplained particle number. The report should allow a technical reviewer to understand:

• where the sample was collected;
• what conditions existed;
• which particle channels were measured;
• how much air was sampled;
• which acceptance criterion was used; and
• what factors may have influenced the result.

What Can Cause a High Particle Count?

A high particle reading does not automatically prove that a HEPA filter has failed.

Potential causes may include:

HVAC and Filtration

• damaged or overloaded filters;
• improperly seated filters;
• leakage around filter frames;
• duct contamination;
• airflow imbalance;
• unsuitable filter grades;
• poor filter-maintenance frequency; and
• uncontrolled outdoor-air ingress.

Room Integrity

• gaps around doors;
• unsealed cable penetrations;
• damaged ceiling panels;
• openings around services;
• pressure-control problems; and
• frequent movement of unfiltered air from adjacent areas.

Personnel and Activities

• excessive movement;
• unsuitable clothing;
• incorrect gowning;
• excessive occupancy;
• open doors;
• poor material-transfer practices; and
• unnecessary activity during testing.

Processes

• powder handling;
• cutting or grinding;
• packaging;
• fibre-generating materials;
• compressed-air cleaning;
• process leakage; and
• equipment friction.

Housekeeping

• dry sweeping;
• unsuitable wiping materials;
• accumulated dust;
• dirty tools;
• cardboard inside controlled areas;
• ineffective vacuuming; and
• neglected ceiling, wall or raised-floor spaces.

Temporary Events

• construction;
• drilling;
• maintenance;
• filter replacement;
• cable work;
• movement of stored materials; and
• cleaning immediately before sampling.

A high result should lead to a structured investigation. Repeating the measurement without understanding the cause may only produce another unexplained number.

Learn more: What Causes High Particle Counts in Cleanrooms and Controlled Areas?

What Particle Count Testing Cannot Establish by Itself

Airborne particle counting does not independently confirm:

• particle chemical composition;
• particle toxicity;
• viable microbial concentration;
• the exact source of every particle;
• regulatory PM2.5 or PM10 mass concentration;
• HEPA-filter leakage location;
• filter-integrity compliance;
• airflow velocity;
• air-change rate;
• differential pressure;
• recovery time;
• gaseous contamination;
• corrosive contamination;
• surface cleanliness; or
• complete cleanroom qualification.

Additional testing may be required.

For example:

• suspected HEPA leakage may require a dedicated integrity test;
• suspected microbial contamination may require viable monitoring;
• suspected ventilation failure may require airflow measurements;
• suspected pressure imbalance may require differential-pressure measurements;
• suspected particulate-mass exposure may require separate PM monitoring; and
• suspected corrosive contamination may require specialised assessment.

Transparent disclosure of limitations produces a more reliable report than an overly broad certificate.

When Should Particle Count Testing Be Conducted?

Particle-count testing may be considered:

• before commissioning a controlled area;
• during classification-related assessment;
• as part of routine monitoring;
• before an audit;
• after renovation;
• after construction;
• after HVAC modification;
• after filter replacement;
• after major maintenance;
• following an abnormal environmental result;
• after a contamination complaint;
• after nearby construction;
• before commissioning a server room;
• after visible dust accumulation;
• after sealing or filtration improvements;
• during an investigation; or
• to establish baseline data for trend monitoring.

There is no single testing frequency suitable for every cleanroom or controlled environment.

Frequency should consider:

• room classification;
• process risk;
• product sensitivity;
• applicable standards;
• customer requirements;
• facility monitoring plans;
• historical performance;
• maintenance activity;
• occupancy;
• frequency of abnormal events; and
• consequences of contamination.

Frequently Asked Questions

What is airborne particle count testing?

It is the measurement of the number of airborne particles at specified size thresholds within a defined volume of air.

Which particle sizes can Perfect Pollucon measure?

Our PCE-PCO 1 provides channels at 0.3, 0.5, 1.0, 2.5, 5.0 and 10 µm.

Can Perfect Pollucon test cleanrooms under ISO 14644-1?

We can undertake particle-count measurements and classification-related testing support where the required class, particle sizes, room area, sample volume, locations, occupancy state and instrument suitability are compatible with the agreed scope.

Can you perform non-viable particle monitoring?

Yes. Routine non-viable particle monitoring can be conducted at agreed locations and frequencies, with comparison against established facility criteria where available.

Can you test server rooms and data centres?

Yes. Testing can support baseline assessment, location comparison, dust-ingress investigation, post-cleaning verification and periodic monitoring.

Is particle count testing the same as PM2.5 or PM10 monitoring?

No. Particle counting measures particle numbers by size. PM2.5 and PM10 monitoring generally reports estimated particle mass in µg/m³.

Is particle counting the same as HEPA-filter integrity testing?

No. Particle-count measurements may indicate a possible filtration concern, but a dedicated HEPA-integrity test uses a different procedure and equipment.

Does the particle counter identify the type of particle?

No. It counts and categorises particles by size but does not determine their chemical or biological composition.

Will the report provide a pass or fail conclusion?

A pass/fail conclusion can be provided where an appropriate and agreed acceptance criterion applies. Otherwise, the findings are reported as a baseline, comparison or investigation result.

Can testing be repeated after corrective action?

Yes. Before-and-after measurements are useful for evaluating the effect of cleaning, sealing, filtration, maintenance and operational improvements.
