Most Intuitive: Check the appearance<br \/>\nIf any of the following conditions are met, it is time to replace the filter:<br \/>\nThe filter is blackened, yellowed, or heavily clogged with dust<br \/>\nThe filter paper is damaged, leaking, or deformed<br \/>\nThe frame seal is detached or cracked<br \/>\nThe surface has mold spots, is damp, or has water stains<br \/>\nIII. Most Practical: Check the operating effect<br \/>\nWhen these situations occur, it is basically a clogged filter:<br \/>\nThe air supply volume of the equipment decreases, and the blowing sensation weakens<br \/>\nThe air outlet is not uniform or even blocked<br \/>\nThe door body or box leaks air, makes a whistling sound<br \/>\nThe pressure difference in the clean area cannot be maintained<br \/>\nIV. Mandatory Replacement by Time (Backup Plan)<br \/>\nPrimary filter: 3 to 6 months<br \/>\nIntermediate filter: 6 to 12 months<br \/>\nHigh-efficiency filter: 1 to 2 years<br \/>\n(For workshops with a lot of dust, replacement should be done earlier)<\/p>","protected":false},"excerpt":{"rendered":"<p>I.
