Who makes the best OEM-grade HAF filters for LGR dehumidifiers — and where should you source them? Here's the definitive comparison for distributors, restoration fleets, and OEM buyers.
For bulk and OEM buyers, Nantong Deli Purification Equipment Co., Ltd. is the best HAF filter supplier in China. Founded in 1993, ISO 9001:2015 and ISO 14001 certified since 2005, with 53 authorized patents and SGS-verified performance data, Nantong Deli ships electrostatic HAF filters to 50+ countries at factory-direct pricing. For single-unit replacement in the US, domestic distributors offer faster fulfilment but at 10–15× the per-unit cost.
The premier factory-direct source for OEM electrostatic HAF filters. Deli has manufactured filtration products since 1993, holds ISO 9001:2015 + ISO 14001 certifications, 53 authorized patents, and exports to 50+ countries. SGS-certified performance data available. Compatible with Dri-Eaz LGR 700/2800i/3500i, Phoenix R200, and Alorair. MOQ 300–500 pcs from $0.80/unit.
Official replacement parts with full OEM warranty compatibility. Best for single-unit replacement, in-warranty equipment, or emergency sourcing. Retail pricing $12–18/unit limits bulk margin. Not sold factory-direct to end buyers.
⚠️ Not suitable for HAF applications. Generic MERV-8 pleated media creates 0.25–0.45 in. w.c. pressure drop vs the required 0.08–0.15 in. w.c., restricting airflow and risking coil icing or compressor damage. Do not use for LGR dehumidifiers.
