Frequently Asked Questions

What is the difference between HAC-504 and HAC-504AW?

HAC-504 and HAC-504AW are the same physical filter. The "AW" suffix indicates the Air Washing variant, which Honeywell uses on models marketed with air washing / pre-filter capability. Both use the same wick dimensions (235 × 146 × 95 mm) and Nantong Deli's DL-WK-HAC504 replaces both.

Which Honeywell models use the HAC-504 filter?

The HAC-504 is one of Honeywell's most common wick filters, used across: HCM-300T/305T/310T/315T/350/350B Series, HEV-300/312/355 Series, HCM-500/600/710 Series, HCM-1000/2000 Series. Contact us with your full model number if unsure.

How often should the HAC-504 wick be replaced?

Replace every 1–2 months. The HAC-504's compact design means it reaches saturation faster in hard water areas. Replacement is indicated when the output humidity level drops noticeably or the wick becomes stiff with mineral deposits.

Can I order HAC-504 replacements with private-label packaging?

Yes. Nantong Deli offers full OEM/private-label services: custom box printing, multilingual inserts, barcode labeling. MOQ 500 sets. Sample in 7 business days.
