Need gas-phase filtration or cleanroom equipment?
Ask about activated carbon filters and fan filter units. For gas-phase selection, include the target contaminant, concentration, temperature and humidity. For an FFU, include airflow, power supply, controls and the required filter class.

Three steps to a suitable filter
01 · Identify
Send actual dimensions, the existing label and your application. Include the seal and frame details.
02 · Compare
Review efficiency, airflow and initial pressure drop together. Confirm available fan capacity and operating conditions.
03 · Confirm
Agree the configuration, supporting documents, quantity and delivery requirement before ordering.

Tell us what you need
Request a filter selection or quote
You do not need every specification to start. A clear label photo and actual dimensions are often the best first step.
Useful details
Width × height × depth, quantity, existing grade and where the filter is installed. Add airflow, pressure drop or temperature if your application specifies them.
Submit your requirements directly to our team. If you have photographs or drawings, mention them in your enquiry and we can follow up by email.
Common selection questions
Can I replace a filter using its nominal size?
Check actual dimensions, frame and seal details first. Nominal labels can differ from the physical size, and a matching width and height do not confirm performance.
Is a higher efficiency always better?
Efficiency must be considered with airflow, resistance and the system design. Review the proposed filter at the required duty point before changing grades.
Does a HEPA filter make an installation compliant?
A filter grade describes tested filter performance. The housing, installation seal, airflow and any required installed testing also need to satisfy the project requirements.
Can I obtain a datasheet or performance curve?
Include that request with your enquiry. PARSWOOD™ can review available documentation for the proposed configuration, rather than applying one curve to an entire family.
