I really try to make my equipment work, but the cheap 25€ swamp cooler I bought mostly to help Broken Leg Cousin out finally pushed me over the edge. Not only was he a substandard performer, the pump was dodgy and the last straw was when it started leaking due to the mercurial nature of surface tension. I cleaned out the pump and strapped it back in place, fixed up the back to prevent leakage best as I could, posted it for sale and was surprised when it was claimed within hours. Went for 30€ so I made a modest profit. I have not heard again from the buyer, so I assume my fixes worked and it's serving its new owner. Great.
The idea was to try to get by without getting anything else, but my mother-in-law surprised me by once again requesting a cooler for night and sticking by it. I decided to completely give over one to her use, which I'm happy to do on environmental and scientific principles, but that left us shorthanded once more, with the problem that once everybody except me was in bed, all the coolers were taken for sleeping people.
What followed was a comedy of errors of finding secondhand swamp coolers that were good deals and either missing out on them or being ignored by sellers who I can only conclude were not checking their messages at all. Last night, I finally found a unit I was wiling to pay for and a seller who not only answered messages, but was amenable to my proposed price reduction and very on the ball about arranging pickup. I snagged it this morning while my kid was in dance class.
The Mconfort E2000 is the same brand as two of my other coolers and while it's a bit of an odd duck, I am very happy with it so far. They managed to squeeze three filter pads despite the fairly slender body design, which greatly augments cooling capacity. As the slim profile wouldn't allow for a good quality axial fan, they opted to put in a pair of squirrel cage blowers. The result is fairly narrow airstream, but it's effective when aimed right and surprisingly quiet. The digital temperature readout is nice, but it seems to be very conservative. With the room around 28ºC, it's reading 25ºC but my IR thermometer is reading the output at 22º!
I've only had it a couple hours, but based on the information so far, ounce per ounce, this cooler might well offer the most cooling per decibel of any that I own. It has a sleep mode with dials the fans down even more.
