Aldehydes & alcohols removal

Clean rooms · laboratory air · museum and archive air

Also called: acetaldehyde, acrolein, low-molecular-weight oxygenates

How it is removed

Short-chain aldehydes and alcohols are small, polar and weakly held, so physical adsorption alone releases them again as conditions change. A permanganate-impregnated medium oxidizes them instead, and a reactive impregnation fixes formaldehyde to the surface rather than storing it. For formaldehyde specifically see the dedicated page.

Recommended grades

The specification that decides it Whether the mechanism is oxidative or physical — desorption risk depends on it
Test against your own duty Capacity depends on inlet concentration, temperature, humidity, contact time and competing species. Nothing here is an assurance that a grade will perform in your service — it is a starting point for a trial. Trial batches run from 1 to 10 tonnes.
