If a listing does not answer you, write before you order. A short note is enough. Name the product, the quantity, and the job.
What to include
- The product name, copied from the title.
- The quantity, and the option if there is one: membrane, diameter, and pore size.
- The job: what you are filtering, storing, or trying to keep within reach.
A larger order uses the same three lines. Say how many you need. Shipping and returns each have their own page. This form will not turn those pages into a promise.
If a fit has not been checked, the reply will say that. We do not add a review, a certificate, or a compatibility line to close the question.
