Frequently Asked Questions

What is the difference between the AIRCARE 1043 and 1043SS?

The 1043 and 1043SS have the same filtration media — the "SS" suffix indicates the Space Saver housing variant. Both use the same wick dimensions (10.5" × 12" × 4") and Nantong Deli's DL-WK-AC1043 is compatible with both.

How often should the Essick Air 1043 wick be replaced?

AIRCARE recommends replacing the 1043 wick seasonally — typically at the start of each heating season. In hard water areas or year-round use, every 3–4 months. The 1043's large surface area means it holds more mineral deposits before performance degrades noticeably, but the scale still reduces absorption capacity over time.

What is the AIRCARE Trapmax filtration technology?

Trapmax is AIRCARE's proprietary media treatment that increases mineral trapping efficiency while maintaining high evaporation rates. Nantong Deli's OEM-equivalent DL-WK-AC1043 replicates this performance through its patented composite fibre construction, validated through in-house CADR testing.

Can I order bulk 1043 replacements with custom branding?

Yes. Nantong Deli offers full OEM/private-label production for the 1043-size wick: custom packaging, brand printing, and barcode labeling. Minimum order is 500 sets. Free sample in 7 days. Contact amanda@ntdeli.top for specifications.
