Otherwise it “recycles” your cool, conditioned air from inside your home and pulls it into the unit, pushes it over the compressor, and then wastefully deposits it outside through the single hose
Products that preference and privilege form over function are frustrating when you need consistent results. I don’t care how elegant the washing machine looks and feels like in front of me, I only care how efficient it is at getting my clothing sanitized and smelling wonderful again. That’s why I’ll look for the old washers that still have agitators in the middle of the drum. They’re better at moving the fabric around and getting the water and detergent to fully immerse into the threads and get out whatever bacteria or funk that has gathered through normal, daily use. On top of that, these washers are easier to repair. For instance, I have a stackable washer and dryer but the washer is an older style agitator washing machine. When the locking mechanism for the lid broke and quit engaging, I couldn’t use the washer because of its safety features. But I found the part online for $33 and had it at my door in two days. The wires are attached to a plug and it comes out easily, allowing me to fix my washing machine in minutes. Although, something doesn’t have to be readily repairable by a novice for it to be a smarter purchase. Case in point—portable air conditioners are only smart if you can get a unit with two hoses, with one pulling in outdoor air to cool the hot compressor inside. Otherwise it “recycles” your cool, conditioned air from inside your home and pulls it into the unit, pushes it over the compressor, and then wastefully deposits it outside through the single hose. That’s why I generally dislike most portable air conditioners.
