How to measure an air filter.

Record the label, the actual dimensions and a few clear photographs. Our team reviews the information before a replacement size is confirmed.

Six steps.

  1. 1Check the existing filter label and record any product or size reference.
  2. 2Measure the actual filter width, height and depth in millimetres.
  3. 3Photograph the whole filter and a close view of its frame, media and label.
  4. 4If available, photograph the opening and retain the equipment reference.
  5. 5Tell TAF whether the measurement is from the filter or the opening.
  6. 6Send the information for review before assuming that a replacement size is confirmed.

Width and height are measured across the face of the filter. Depth is measured through the frame, front to back.

Labels and measured sizes can differ.

The size printed on a filter label is often a nominal size, which may not match the actual measured dimensions. Always measure the filter itself and record both the label and your measurements.

Measured the opening instead?

That is fine. Tell us that the measurement is from the opening. Our office will determine the appropriate allowance for your equipment rather than applying a standard deduction.

Useful product questions.

Questions worth asking before confirming a replacement filter.

  • Is this the same size as the existing filter?
  • Which media and frame options are actually available?
  • Can this specific model be washed, and how?
  • What operating conditions affect maintenance?
  • Which specification or test document supports the rating?
  • Will this fit the existing housing and airflow arrangement?
  • How are production timing, collection and freight confirmed?

Not sure of the size or filter type?

Send a clear photograph of the filter and any label, together with the system details if available. We can review the information and advise what else is needed for a quote.
