This appears to be a single hose ac. I recommend that you pass on this. If you must get a portable ac unit, spend the money on a dual hose.
This seems to be one of many things people gripe about I'm not sure why. There has to be some insulating factor for heat radiating back into the room and it really just seems to be there for pressure differential. I don't see that being a problem in my case but we will see when fire session comes.
I have had a couple of older ones of these. Noisy and problem getting rid of water. One quit just after warranty and one works-just can't sleep with it in same room . Heard good things about inverter window units which window near all way down, really quiet.

Only reason I'm willing to give it a shot is I need one for this summer and I doubt the price is going to go down anytime soon. I do hope is stays somewhat at 44db . Plus its Costco...

They literally suck air they just cooled back over the hot condenser and then blow it out the window. Single-hose ACs are incredibly inefficient. It will probably help with humidity though, so long as it's not a pain to drain.
It's an internet talking point that doesn't actually matter that much in practical application.
The hose in itself radiates a massive amount of heat back into the room, since it is not insulated, and that is the biggest inefficiency for dual and single hose units. Insulating that will make a better difference than adding a dedicated intake hose, otherwise its a long space heater sitting in the middle of your room. The negative pressure thing is real, but running your kitchen or bathroom ventilation fans creates negative pressure too and it doesn't drastically change the temperature of the house (if anything, it usually helps cool it).
Bottom line is that a single hose unit will cool your room down just fine.
This is why I can't stand the use of thermal efficiency being thrown around so recklessly.
Yes, the idea that your dual hose separating the hot and cold away is correct in theory but the reality may not be when real efficiency is found in insulation and output/input. I've found no measured data in a lab comparing dual vs single hose portable AC units, all of this is based on manufacture clams.
If I wanted efficiency I would go with a split system with high BTUs and remove all heat including myself from the equation versus a $40 insulated hose that is likely all that is needed in this case but without real measurements no one knows. I would love a link to a study because I would love to be wrong.

I've had this LG Inverter AC for the last 2 years and it's great. Much better than my old Black and Decker portable AC or my friend's whynter dual hose.
Last year during the heat wave where temps hit 90s and 100s, this kept my condo cool at a nice 70 degrees. Best thing is that this is probably the quietest portable AC you can buy due to the inverter, you can sleep with it right next to you whereas my old one was like a rumbling engine.
I've also never had to drain this, I even opened it up to check one and there was no water. There's a setting where you long press one of the buttons such that it always evaporates for an additional 15 minutes after you turn it off.

With a single hose AC, lets say it's 100 degrees outside. The makeup air has to come from somewhere and that somewhere is Outside. So you are just Sucking in 100 degree outside air into the house through the paths of least resistance: gaps in the doors and windows, vents, fireplace, etc.
To the other point, yes it absolutely makes sense to wrap the hoses with insulation. I used something like this in combo with a blanket material. https://www.amazon.com/VIVOSUN-In...r=8-3&th=1

Is there some reason you can't insulate the output hose of a dual hose?

Fire season is what will get you. The little bit of outside air that gets pulled in on a single hose unit isn't enough to to drastically effect the cooling. May not be quite as efficient but you will still cool the room quite a bit. But when air quality was bad last summer, my indoor air quality meter would show poor quality whenever I had the ac on.
So if you live somewhere prone to wildfire smoke, definitely go with dual hose.
I first had the whynter ARC-14S because it's dual hose and more energy efficient. The problem that I had with the whynter is that it brought in way too much humidity and it struggled to keep the humidity down. So I was a bit disappointed with that purchase, so I took a gamble with the LG, and I paid over $600 for it. It's actually very good at removing humidity. The negative pressure is not really a big deal since the air finds its way in. It's actually more energy efficient than the dual hose, the dual Inverter is a game changer. Because it's a dual inverter, when it doesn't need to cool as much, it just runs at a lower watts and it's removing/lowering the humidity. It has more features than the whynter. The scheduler is amazing because we can turn it on 1 hour before bed each day, and auto turn off in the morning. The auto rotating swivel is nice, but kinda useless imo, just looks nice. If you're looking for a portable AC, get this one, you won't be disappointed.

I don't see this model in the article

The next best thing to this would be a window inverter unit such as: https://www.homedepot.c
