Delicate electronic equipment is subject to harmful attack by acidic gases in the atmosphere. It is therefore often desirable to filter out such gases. In the past, filters employing sodium bicarbonate have been used for this purpose. It has now been found that much better results are obtained using sodium carbonate instead of sodium bicarbonate. Sodium carbonate ha increased gathering capability for acidic gas. Furthermore, increased filter life and improved reliability are also obtained.
