What Is a HEPA Filter and How Does It Work?
A HEPA (High-Efficiency Particulate Air) filter traps fine airborne particles such as dust, pollen, mould spores and particles that carry microorganisms. Under the US standard, a True HEPA filter captures at least 99.97% of 0.3-micron particles. Under the European standard EN 1822 / ISO 29463, filters are graded at their most penetrating particle size (MPPS).
The filter media works through three mechanisms:
- Interception: particles following the airflow touch a fibre and stick to it.
- Impaction: larger particles cannot follow the air around a fibre and hit it directly.
- Diffusion: the smallest particles move erratically and collide with fibres.
A HEPA filter performs well only when it is correctly selected, sealed and maintained. A pre-filter upstream protects the HEPA filter and extends its service life.

Where HEPA Filters Are Used Around Bhosari
Bhosari MIDC and the neighbouring Pimpri Chinchwad belt are among Pune's main industrial zones, with engineering, auto-component, packaging, chemical, food and pharmaceutical units. HEPA filtration is typically specified for:
- Pharmaceutical and medical device units: cleanrooms, laminar air flow units, pass boxes, sampling booths and dispensing areas.
- Food, beverage and packaging units: sensitive filling, packing and preparation zones, where the design calls for HEPA.
- Electronics, instrumentation and precision assembly: low-particle work areas.
- Quality control and testing laboratories: controlled air and particle control for sensitive measurement and testing.
- Industrial cleanrooms and controlled rooms: supply air through terminal boxes or FFUs.
- Hospitals and diagnostic labs in Pimpri Chinchwad: operation theatres, ICUs and sample-handling areas.
- Commercial buildings and offices: final-stage filtration in central HVAC where better air quality is needed.
The right grade depends on your applicable standard, such as ISO 14644 cleanroom class, GMP requirements for pharma, or hospital ventilation guidelines. Your designer or validation team should confirm the grade.
Protecting HEPA Filters in Dusty Industrial Areas
Industrial air in MIDC areas usually carries heavy dust, and an unprotected HEPA filter can clog early. A staged setup normally works better:
- Coarse pre-filter (for example G4) to catch large dust.
- Fine filter (pocket or bag type, for example F7 to F9) to catch finer particles.
- HEPA filter (H13 or H14) as the final stage.
Monitor pressure drop across each stage and replace the pre-filters first. This protects the HEPA filter, keeps airflow steady and lowers running cost. Your HVAC designer should confirm the exact stages for your process.
How to Choose the Right HEPA Filter
- Filter grade: choose H13 or H14 to match your required air cleanliness.
- Airflow: match the filter's rated airflow to your AHU or terminal box.
- Pressure drop: check initial resistance so your fan can handle it as the filter loads.
- Size and construction: pick mini-pleat, deep-pleat, box-type, gel-seal or V-bank to suit your housing and space.
- Sealing: confirm that the gasket or gel seal fits your frame to limit bypass.
- Maintenance: plan for pre-filters, pressure monitoring and easy replacement.
Documents to ask for before buying: the filter's efficiency grade, dimensions, rated airflow, initial pressure drop and the test report or certificate for the grade claimed.

FAQs: HEPA Filters in Bhosari
Ans: They remove fine airborne particles in hospitals, laboratories, cleanrooms, pharmaceutical units, food and packaging plants, industrial plants and commercial HVAC systems.
Ans: In most industrial settings, yes. Dust loads are high, so coarse and fine pre-filters upstream take most of the dust and let the HEPA filter last longer. The exact stages depend on your process and your HVAC design.
Ans: We supply H13 and H14 filters in mini-pleat, deep-pleat, box-type, gel-seal and V-bank designs, plus HEPA terminal boxes, pre-filters and pocket filters, delivered from our Pune facility.
Ans: Yes. We can make filters to your size, frame material (GI or aluminium) and grade. Share your drawing or existing filter details for a quote.
Ans: No. Washing or cleaning can damage the media and the seal. Clean or replace the pre-filters more often to protect the HEPA filter.
Ans: There is no fixed lifespan. It depends on dust load, airflow, operating hours and pre-filtration. Facilities usually replace a filter when its pressure drop reaches the limit set by the manufacturer, or if an integrity test fails.
Ans: Replace it if the pressure drop reaches the manufacturer's final limit, airflow falls, the filter is visibly damaged, or a leak test fails.
Ans: Price depends on grade, size, construction, frame material and quantity. Send us your requirements for a quotation.
