How long should a good dehumidifier last?

r/BuyItForLife users report 6–12+ years from older Frigidaire compressor units, while complaints across r/homeowners and YouTube about newer budget brands cite failures inside the first year or two. Setting the humidity target to 50–55% rather than running continuously at 30% extends compressor life significantly, according to a long industry-AMA thread on r/Dehumidifiers.
