The quick change design allows filter replacement without shutting off water supply or using housing wrenches. Sediment prefilters protect the RO membrane from particulate damage, while carbon block prefilters remove chlorine and organics. The carbon block postfilter provides final polishing before the faucet. Not compatible with standard threaded housing systems or other RO brands.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"pro-tip\"\u003e\n💧 Replace prefilters on schedule even if water quality
