Purchased the best one from Lowe's. Got the extended warrantee. Saved the receipts in a special warrantee file. Died within the warrantee period. Replaced free of charge.
That statement applies to three dehumidifiers and one washer. Average dehumidifier life, less than 4 years.
(Dehumidifiers in good working order are vital when there is any type of lift out bridge or removable access provision.)
My local Lowe's is very consumer friendly.
Side note: as a solid wood flooring contractor, our products are guaranteed by the particular manufacture to perform satisfactorily only when the room's humidity is within 35% to 55%. Otherwise the guarantee is null and void.
