Honeywell HPA4200B vs Levoit LAP-C341S-WUSZ
A spec-only comparison using ENERGY STAR certification data. We have not tested either unit, and features like noise, filter price and build quality are not covered here.
- Cleaning speed: the Levoit LAP-C341S-WUSZ has the higher smoke CADR (161 vs 144 cfm, 12% more).
- Running cost: the Honeywell HPA4200B uses less electricity per ENERGY STAR (137 kWh/yr), about $1.46/yr less at the U.S. average rate (estimate).
- Room size: by AHAM's 2/3 rule, up to about 216 sq ft vs 242 sq ft.
Both sit in ENERGY STAR data as Small rooms (under 150 cfm) / Medium rooms (150–249 cfm) units by smoke CADR. Listed differences: only the Honeywell HPA4200B lists an air-quality-sensor auto mode. Over 5 years at the U.S. average rate, the electricity difference is about $7.32 (estimate).
