The manual describes chilled water in a 41\u201350\u00b0F range.

That certification is separate from Waterdrop\u2019s laboratory contaminant-reduction results.

The PFAS entries describe results at the start of sample operating life. Check the latest exact-model report for your concern; we have not independently tested these reductions.<\/p>\n<\/div><\/div><div class=\"et_pb_toggle_5 et_pb_toggle et_pb_toggle_item et_pb_toggle_close et_pb_module et_flex_module\"><h3 class=\"et_pb_toggle_title\">How often do the A1 filters need replacing?<\/h3><div class=\"et_pb_toggle_content clearfix et_flex_module\"><p>The listed limits are up to six months or 550 gallons for A1-CF and up to 12 months or 1,100 gallons for A1-RO. Actual service life varies with consumption and water quality. Follow the unit\u2019s prompts and the current replacement instructions.<\/p>\n<\/div><\/div><div class=\"et_pb_toggle_6 et_pb_toggle et_pb_toggle_item et_pb_toggle_close et_pb_module et_flex_module\"><h3 class=\"et_pb_toggle_title\">Can the A1 provide unlimited cold water?<\/h3><div class=\"et_pb_toggle_content clearfix et_flex_module\"><p>No. The manual lists a 0.26-gallon cold-water tank. After several drinks, the compressor may need time to chill more water. The 100-GPD figure is a rated filtration-production capacity, not an unlimited cold-water dispensing rate.<\/p>\n<\/div><\/div><div class=\"et_pb_toggle_7 et_pb_toggle et_pb_toggle_item et_pb_toggle_close et_pb_module et_flex_module\"><h3 class=\"et_pb_toggle_title\">Why is my new A1 not producing cold water yet?<\/h3><div class=\"et_pb_toggle_content clearfix et_flex_module\"><p>The manual describes a two-hour cooling startup delay for compressor protection. After that, check that cooling is enabled and that night mode is not preventing refrigeration. Follow the A1 troubleshooting guide if the problem continues.<\/p>\n<\/div><\/div><div class=\"et_pb_toggle_8 et_pb_toggle et_pb_toggle_item et_pb_toggle_close et_pb_module et_flex_module\"><h3 class=\"et_pb_toggle_title\">Does the A1 add minerals back to the water?<\/h3><div class=\"et_pb_toggle_content clearfix et_flex_module\"><p>The standard A1 listing describes CF and RO filtration, not a remineralization stage.
