Mine is the Logik 8000 btu. I bought from Currys, they weren't listed on their website and they were tricky to find in the store. Even employees said they didn't think they done them, but I found them tucked away next the exit in Lakeside without any prices on them.
Most units in this price range will make a similar amount of noise, it's a fridge compressor and a strong fan in a small unit, so you can imagine what such a combo sounds like! The noise is definitely intrusive, but not unbearable. I have one right next to my PC and I just wear headphones when it's on. It can be tricky working out who actually makes these, there appear to be 3 or 4 OEMs in China and they just get rebranded and restyled. Of the few I've seen in person, I probably prefer the units made by Midea. They supply units to Electrolux, the 8,000 btu Logik from Currys is a Midea and from the looks of it the Clas Ohlson air con is a Midea too, but they're sold out.
I have a similar one in my office and it’s too noisy most of the time. There are ones that claim to be quieter but not sure how quieter they are.
How unbearable is the noise...? I cant seem to find any alternatives near this price.
Simular one I bought came with a long flat plastic thing which allows you to fit in a window.
