Top 10 HEPA Filter Manufacturers in India
Written by Neeraj Goel, Founder, Best Air Filter (Fiilters). 10+ years of experience manufacturing HVAC and industrial air filters in Delhi.
If you’re buying HEPA filters for a hospital OT, a pharma cleanroom, or an HVAC contract, the manufacturer you pick affects your compliance. A supplier without proper test paperwork can cost you a failed GMP audit. The wrong grade can fail your ISO classification test on day one.
This guide covers 10 manufacturers supplying HEPA filters in India in 2026: certification, minimum order quantity, and what kind of buyer each one suits.
About this list
We manufacture HEPA filters ourselves, at a Delhi facility, and have quoted jobs for hospitals, pharma units, and HVAC contractors for over 10 years. This list is built from manufacturer product pages, published cleanroom standards (EN 1822, ISO 14644), and that hands-on quoting experience.
We’re including our own listing below, Fiilters, and disclosing that plainly. We’re not a neutral directory. Google’s guidance on people-first content asks writers to be clear about who wrote a piece, how it was produced, and why, so buyers can weigh a recommendation with that context in mind.
Who: Neeraj Goel, a working HEPA filter manufacturer, not a content agency. How: sourced from manufacturer websites, published cleanroom standards, and 10 years of direct quoting experience, then checked for accuracy before publishing. Why: to help buyers shortlist a supplier faster, while being upfront that one listing here is our own.
Why the manufacturer matters more than the price tag
Most Indian cleanrooms run on H13 or H14 grade HEPA filters, classified against ISO 14644-1, the international standard for cleanroom air cleanliness. H13 typically covers ISO 7 to 8 environments. H14 covers ISO 5 spaces: sterile pharma rooms, operation theatres, ICU and NICU areas. Get the grade wrong and your validation fails, regardless of how good the filter media is.
A manufacturer worth buying from should hand you three things without being asked:
- An EN 1822 test report for the specific grade you ordered
- A batch-wise DOP or PAO leak test certificate
- Material specs for the media, frame, sealant and gasket
If a supplier can’t produce these on request, that’s a signal to look elsewhere, no matter how competitive the quote looks.
A failed cleanroom validation has real cost. Pharma units lose production days waiting for a re-test. Hospitals risk an audit observation on their next NABH cycle. The filter itself is usually a small line item in a project budget, often a few thousand rupees against a project worth lakhs. The cleanup after a failed validation runs far higher.
What experience, expertise, authority and trust mean for a list like this
Google’s guidance on people-first content asks writers to show experience, expertise, authority, and trust, often shortened to E-E-A-T, before asking readers to act on what they read. For a supplier comparison, that breaks down into four checks:
- Experience: has the writer actually sourced, specified, or quoted these filters, not just read about them
- Expertise: does the content get technical details right, like grade-to-ISO-class mapping and test standards
- Authority: is the source a working manufacturer or genuine industry participant, not an anonymous content farm
- Trust: does the piece disclose bias, list a real address and contact, and avoid inflated claims
We’ve tried to meet all four here. We’re a manufacturer, we’ve disclosed that upfront, and every technical claim in this guide ties back to a published standard, EN 1822 or ISO 14644, rather than a marketing line.
1. Fiilters (hepafilter.in)
Fiilters has run its own factory in Delhi for over 10 years, making HEPA filters, bag filters, pre-filters, and industrial panel filters direct to buyer. The plant is ISO certified and builds to H13/H14 efficiency standards. MOQ is 10 units, low enough for a single hospital ward or a small lab, not just bulk buyers.
The company takes OEM and fully custom orders from a CAD drawing or housing measurement, dispatches in 3 to 5 working days across India, and runs AMC contracts for scheduled replacement. The full product range and client list are listed on our about us page.
Good fit: buyers who want factory pricing with no trading middleman, and facilities that need a custom-cut filter in a small batch.

2. Enviro Tech Industrial Products
Based in New Delhi, Enviro Tech has made HEPA and ULPA filters for cleanroom and industrial use for several years. Their media is a water- and fire-resistant microglass fiber paper, sold in both box-type and round formats.
Good fit: buyers sourcing for laminar flow benches or nuclear-grade cleanrooms.
3. United Filter Industries Pvt. Ltd.
Headquartered near Pune, United Filter Industries builds HEPA filters for fine particulate, fume, and gas removal across industrial and cleanroom settings. They also make dust collectors and broader air filtration systems.
Good fit: industrial plants that need dust collection equipment alongside HEPA terminal filters, from one supplier.
4. AAF India
AAF India, based in Greater Noida, focuses on high-efficiency filtration for hospitals, cleanrooms, and laboratories. Their construction is built for dust, pollen, and airborne bacteria control in critical spaces.
Good fit: hospitals and labs where bacteria control is the main concern.
5. India Filters
India Filters operates out of Ahmedabad and supplies pharma, semiconductor, and hospital clients where air cleanliness isn’t optional. Their filters are built to international benchmarks, which matters if your facility exports or serves global pharma clients.
Good fit: pharma and semiconductor manufacturers who need documentation aligned with international standards.
6. Thermotech System
Thermotech System, based in Vadodara, supplies custom filtration for aerospace, automotive, and healthcare clients. Their strength is tailoring specs to unusual housing sizes and operating conditions outside standard HVAC use.
Good fit: buyers in aerospace or automotive with non-standard filtration needs.
7. TFI Filtration
TFI, headquartered in Ahmedabad, is established in India’s HVAC and filtration space, supplying HEPA filters for large commercial and industrial projects, including healthcare and hospitality.

Good fit: buyers with ultra-high efficiency needs in biosafety labs or isolation rooms.
How to choose the right HEPA filter manufacturer
Check certification before price. Ask for the EN 1822 test report and a batch-wise DOP or PAO certificate. A filter without paperwork can fail a GMP or NABH audit, and fixing that later costs more than the discount saved.
Match the grade to your ISO class. H13 for ISO 7 to 8. H13/H14 for ISO 6. H14 for ISO 5 sterile rooms, OTs, and ICU/NICU spaces. Confirm this with your HVAC consultant or the manufacturer directly.
Ask about MOQ early. Some manufacturers only quote for container-scale orders. If you run a single hospital or lab, look for a supplier that accepts 10 to 50 units.
Confirm custom sizing. Standard sizes rarely fit an existing housing without rework. A manufacturer that builds to your CAD drawing saves you an on-site fix later.
Compare dispatch time and AMC support. A 3 to 5 day dispatch window and an AMC option for scheduled replacement matter more over a year than a marginally lower unit price.
Which manufacturer fits which industry
Hospitals and OTs: Fiilters, AAF India, or Map Filters. All three build for ISO 5 sterile spaces and can support an AMC for scheduled replacement, which most hospital procurement teams need for their compliance file.
Pharma cleanrooms: India Filters or Dyna Filters. Both work to grade requirements that pharma auditors check for by name, and both can produce the documentation an FDA or GMP audit asks for.
Electronics and semiconductor plants: D.P. Engineers or India Filters. Contamination control at this scale is about consistency across thousands of filters, not just one high-spec unit.
HVAC contractors and commercial buildings: TFI Filtration or United Filter Industries. Both are set up for project-scale HVAC integration rather than single-unit replacement.
Aerospace and automotive: Thermotech System. Their custom sizing work fits equipment that doesn’t use standard cleanroom housing dimensions.
Frequently asked questions
What is the typical lifespan of a HEPA filter?
Most cleanroom HEPA filters are replaced every 2 to 5 years, depending on airflow and contamination load. Pressure drop monitoring is the usual way to decide when replacement is due, not a fixed calendar date.
What is the difference between H13 and H14 HEPA filters?
H13 suits ISO 7 to 8 cleanrooms and standard HVAC-based environments. H14 suits ISO 5 spaces where a higher sterility level is required, such as pharma rooms, OTs, and ICU/NICU areas.
Can I get a custom-size HEPA filter for my existing housing?
Yes. Most manufacturers on this list accept housing dimensions or a CAD drawing and build to that exact specification, including OEM and private-label orders.
What is a reasonable MOQ for HEPA filters in India?
It varies by manufacturer. Some accept orders as low as 10 units. Others are set up mainly for bulk or container-scale orders, so ask before you shortlist.
Do HEPA filter manufacturers offer AMC contracts?
Several do, particularly those serving hospitals and pharma clients, where scheduled replacement and testing is a compliance requirement, not a convenience.
