Cleanroom filtration is not a one-size-fits-all requirement. Whether you are replacing filters in an existing cleanroom, sourcing filtration for a new controlled environment, or trying to match a non-standard configuration, Atmos-Tech manufactures HEPA and ULPA filtration solutions for critical environments.
Atmos-Tech manufactures HEPA and ULPA filters in-house with standard and custom dimensions, multiple frame materials and specialty seal configurations. Filters are individually tested for performance before shipment, providing cleanroom owners, engineers and contractors with filtration built around their operating requirements.
Need to replace an existing HEPA or ULPA filter?
Send Atmos-Tech your dimensions, specifications or drawings and our team can help identify a configuration for your application.
Replacement HEPA Filters for Existing Cleanrooms
Cleanroom filtration systems eventually require filter replacement as part of routine facility operation and maintenance.
Finding the correct replacement requires more than matching the outside dimensions of the existing filter. Efficiency, airflow, pressure drop, frame construction and seal configuration can all affect the performance of the filtration system.
Atmos-Tech supports replacement filtration requirements for cleanrooms and other controlled environments where HEPA or ULPA filtration is required.
When requesting a replacement filter, provide as much information as possible, including:
- Existing filter dimensions
- Filter depth
- HEPA or ULPA efficiency
- Frame material
- Gasket, gel or knife-edge seal
- Required airflow
- Existing filter manufacturer or model number
- Cleanroom classification
- Quantity required
- Drawings, specifications or photographs when available
Providing these details allows the Atmos-Tech team to evaluate the application and quote an appropriate filter configuration.
Have an Existing Filter You Need to Replace?
You do not necessarily need to start from scratch.
Submit the specifications, drawing or information from your existing filter and let Atmos-Tech review the requirements.

Custom HEPA Filters for Non-Standard Applications
Not every cleanroom uses a standard filtration configuration.
Renovations, legacy cleanrooms, OEM equipment, custom ceiling systems and specialized production environments can require filters with dimensions or construction that differ from standard catalog products.
Atmos-Tech manufactures both standard and custom HEPA and ULPA filter configurations. Available construction options include multiple frame materials and gasket, gel and knife-edge sealing arrangements.
Custom filtration can be particularly valuable when:
- Replacing filters in legacy cleanrooms
- Matching an existing cleanroom ceiling system
- Building custom process equipment
- Designing specialized laminar airflow systems
- Retrofitting controlled environments
- Supporting unique equipment dimensions
- Standard filter sizes will not fit the application
Instead of designing your system around an off-the-shelf filter, Atmos-Tech can manufacture filtration around the requirements of the application.
HEPA vs. ULPA Filters for Cleanrooms
The level of filtration required depends on your cleanroom classification, process requirements and facility design.
HEPA Filters
HEPA filtration is widely used throughout pharmaceutical, biotechnology, healthcare, laboratory and other controlled environments.
Atmos-Tech offers HEPA filtration with efficiencies up to 99.99% according to its current product specifications.
ULPA Filters
Processes requiring a higher level of particulate filtration may require ULPA filtration.
Atmos-Tech offers ULPA filters with efficiencies up to 99.9995% according to its current product specifications.
The appropriate filtration level should be determined based on the requirements of the cleanroom and the process being protected.
Not sure which configuration you need?
HEPA Filter Seal Options
The filter-to-housing connection is an important component of the filtration system.
Atmos-Tech offers filter configurations including:
Gasket Seal HEPA Filters
Gasket seals provide a compression seal between the filter and housing and are used in many cleanroom filtration systems.
Gel Seal HEPA Filters
Gel seal filters are commonly used where a secure seal between the filter and receiving housing is required.
Knife-Edge HEPA Filters
Knife-edge configurations are designed to engage a gel seal in compatible cleanroom ceiling or housing systems.
If you are replacing an existing filter, matching the current seal configuration is especially important.
Filter Frame Materials and Configurations
Atmos-Tech filtration can be configured with different frame materials based on system and environmental requirements.
Current product options include materials such as aluminum, stainless steel and additional frame configurations depending on the application.
When submitting an RFQ, identify the existing frame material or required construction whenever possible.
HEPA and ULPA Filters for Critical Industries
Atmos-Tech filtration supports cleanrooms and controlled environments serving industries including:
Pharmaceutical Manufacturing
