Question: Is there a filter / filtration system?
Document: I love the look of the unit. The installation was easy and the wifi setup with the app was easy. The control of the system on my iPhone works great, haven't tried the geofencing just yet.
It even has a removable (and washable) air filter nested in the right-hand side of the unit! Talk about keeping it fresh!-- In The Window --Once I turned this on for the first time...I was amazed at the power of the cooling unit and the high speed of the fan, definitely a win for my apartment.
I kind of like the constant 'white' noise of an air conditioner as I sleep. (Covers up other more sudden and sharp sounds from the city outside ...)UPDATE:  Just noticed that with a relatively small window size, no matter how the unit is positioned in the window, there isn't enough room for the filter which comes out from the side, to come out.
They should have put the filter anywhere else. I'm not sure I have ever had a window where this wouldn't have been an issue.A lot of reviewers have said the unit is too loud. It is loud but I don't think it's louder than comparable AC's. Based on some of the reviews, I think people are purchasing them for rooms where a smaller AC would be more appropriate.
The only unit I could hear is the Aros... And I thought the current unit I have was loud... I expected better from LG. The placement of the filter is a real inconvenience because the way it slides in and out towards the right. You definitely need enough room to remove it which I do not. Definitely needs more work and I will be returning this unit.
However, putting it on the side means that you CANNOT get it out of the AC once you have installed it inside the window frame! Oh man, I have to bend the filter hard to finagle it out of its dedicated slot.2. When the setting is on COLD, and even on LOW, it makes an annoying, metallic vibrating noise that only disappears if you switch to FAN mode.3.
It will rain in I'm sure, if it ever rains again here, so I'll figure out a workaround.The filter removal is in an awkward place, but not so much in my particular custom installation.Well, it works fine. The fan on high is LOUD. The lowest setting should be the highest, if that makes sense. The low is just right. The Carrier had a whisper-like speed choice, but the compressor was very loud.
The air-filter is difficult to remove as it is located on the side - I opened the window to slide the unit to the other side and about lost the unit trying to see how one would remove it. The air filter's plastic should be more pliable due to the awkward placement. Where the air vents are located on the top of the unit house dust and dirt can fall into the area and there is no way to clean the inside.
In our installation, which has never caused issues with 4 previous A/C's, the filter that slides out to the side has to be bent quite a bit to clear the wall. I suspect it'll break after a few cleanings.The app is buggy and strange. It shows what it claims is the current room temperature, but that seems to be permanently stuck at 81. Each time I set a temperature, after a few moments it changes itself by a few degrees.
The side rails in particular were a pain to squeeze in place. The side panels are just a thin cloth and left small areas open to the outside.The mounting hardware and instructions didn't work for the type of window I have, so the unit is just sort of clamped in there by the window itself.Use------That's all relatively minor stuff compared to these issues:1) The filter loads from the right side. It can't be removed because it bumps against the window sill.
Answer: Yes BUT it's removable from the right side so unless your unit sticks out past the wall/window sill, you'll have to pull the whole unit out of the window to remove it.
