It also helps prevent colds. 【Replacement目安 (Guideline)】 5 seasons to 20 seasons (4 pieces) (The lifespan may be shortened depending on the hardness of the tap water.) If the filter is noticeably dirty and its effectiveness seems to be reduced, it is recommended to replace it promptly. 【Compatible Models】 HD-1500F HD-151 HD-152 HD-153 HD-154 HD-1800F HD-181 HD-182 HD-183 HD-184 HD-2400F HD-242 HD-243 HD-244 HD-PC1500G HD-PC1800G HD-PC2400G HD-PN155 HD-PN185 HD-PN245
