    Idk why this is a news article. Everyone knows anything about this knows that evaporative coolers have a hard cooling limit at the wet bulb temperature and will perform poorly in high relative humidity environments and hot outside temps. They’re not magic. We’ve known this limitation for hundreds of years at this point.

      Sure but you can buy them on amazon for like 20 bucks making them an impulse purchase for people who don’t know how they work and aren’t interested in doing the research, so then they just assume it’s magic and get upset when it doesn’t work.

      yeah, this is just physics. To overly simplify, swamp coolers alone cannot move the indoor climate to a comfortable state if the baseline temperature is above 40 deg C, even if there is 0 water in the air to start with. They can still help in certain climates, but require air conditioning or significant air movement to compensate.
