The cartridge filter does the heavy lifting — trapping dirt, silt, sand, and suspended particles before they reach the pump and heat exchanger.\u003c\/p\u003e\n  \u003cp\u003eA clogged filter restricts water flow below the chiller's minimum threshold (16 L\/min), which forces the pump to work harder, reduces cooling efficiency, and eventually triggers the chiller's flow-rate alert. Replacing filters on schedule — every 2–4 weeks depending on use — keeps flow optimal, water clear, and your chiller running at full performance.\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eWhy 20 micron specifically?\u003c\/strong\u003e At 20 microns, these filters capture particles visible to the eye while maintaining strong flow rates through the cartridge. Going finer (5 or 1 micron) would restrict flow and require more frequent replacement; going coarser (50 micron) would allow visible particles to pass. 20 microns is the manufacturer-specified rating for the DCT system.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003c!-- Features --\u003e\n\u003cdiv class=\"acc-section\"\u003e\n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cdiv class=\"acc-features\"\u003e\n    \u003cdiv class=\"acc-feature\"\u003e\n      \u003cspan class=\"acc-feature-icon\"\u003e💧\u003c\/span\u003e\n      \u003ch4\u003e20-Micron Particulate Filtration\u003c\/h4\u003e\n      \u003cp\u003eCaptures dirt, silt, sand, and suspended particles that cloud water and damage pump components.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"acc-feature\"\u003e\n      \u003cspan class=\"acc-feature-icon\"\u003e📦\u003c\/span\u003e\n      \u003ch4\u003e4 Cartridges Per Pack\u003c\/h4\u003e\n      \u003cp\u003eA 2–4 month supply for regular users.
