I am so tired of dehumidifiers that last just a few years. I keep two units; one for the finished half of my basement (where my 3d printer lives) and one in the unfinished part (where my shop is). After a couple failures, I thought I'd found a good kind, and bought a second one of that kind — only to have the first fail shortly thereafter.

So I found one that was listed on Amazon, sold by the manufacturer and fulfilled by Amazon, with the listing stating "5 year warranty".

When I got it, the warranty is actually six months of covering shipping, one year of general parts and labor but no shipping, three years of parts and labor but no shipping on the refrigeration system only, and five years of parts only and no shipping on the refrigeration system.

I'm pondering sending it back because of the misleading listing. I paid extra for a unit from a company that at least claims to be a US company of many decades' standing, specifically to expect to be able to trust a "5 year warranty", and they definitely didn't live up to my expectations already.

We've had very good luck with the Crane ultrasonics. They just keep going. One of the oldest finally died when its fan gave up the ghost.

@jonhendry Those aren't dehumidifiers, are they? I would expect "ultrasonic" to mean humidifier? Too little water in the air isn't the normal problem where I live... (For us, in North Carolina, a humidifier is for someone who is sick during the winter, when heating means the house has lower relative humidity.)

@jonhendry Oh well! No harm done!

@EdS North Carolina, where I live, has plenty of wet air. (At least... usually!) These aren't for closets, they are for multi-room areas, and the units I need are measured in liters per day they can be expected to remove and pump out of the house (at a reference temperature/humidity, of course).

There are times of the year when the humidity is so high that without a dehumidifier, I could expect the tools in my shop to flash rust. 😬

@mcdanlj I’m using this one in my mountain house crawl space: amzn.to/3XDHl1t (affiliate link!) and it’s run for almost three years fine.

@mcdanlj I think the combination units are the most efficient but cost the most.

The adsorption units are generally bigger and CANNOT extract directly to water but together the heat pump provides the energy 'multiplication' and the adsorber the grunt work. On big building sites the capital cost and unit size are not as important as speed and convenience.

@mcdanlj Yeah I’m not saying it’s the best option, but it’s what I chose 3 years ago after going through hell trying to keep a cheap typical Home Depot-type unit running. My HVAC guy later said “yeah, even those more commercial looking units suck, too.” But so far, anyway….

@djb_rh At least AprilAire had a more honest representation of their warranty on the Amazon listing...
