Review on 🍯 Honeywell HAC-504 Series Humidifier Replacement Filters - Bundle of 2 (Updated Version) by Matt Larsen

The air you breathe at night should be clean and moist enough to avoid dryness and irritation. This is especially true during the pandemic as we try to eliminate any cold or sore throat that might develop into something more serious. These filters clean the air by collecting water from a reservoir at the bottom of the humidifier. If not maintained and replaced when dirty, they can create air pollution that you should avoid. We found that checking the filter in the middle of winter is enough and you have to change it every year. This filter absorbs moisture well and contains a mold inhibitor to extend its life. Others may look the same, but the wicking properties determine the effectiveness of the humidification.
