Rated 4.0 out of 5.0 by TrustyJ Does what it should
This is great for windy days when the fan is not in use to help keep outside air out. If the tabs break or I find air / dust blowing through I will update. Quite bulky to store when not in use.

I bought this grill cover for the master cool slim line window cooler I installed. It fits well and is pretty snug. I have used it for an entire season. I am a little miffed at the strength of the tabs that hold it on though, as one of them broke off a couple of weeks ago after about four months of use. I am very gentle when pulling on them to release them so I really didn't expect one to break off. I suppose perhaps I put on and take off the cover more than most people would though. I cover the cooler anytime it isn't running to keep dirt and mosquitoes from coming into the house and air conditioning from going out.

It fits but, doesn't keep the cold night air out. I put a 1/8" piece of padding in the cover to seal it.

Rated 4.0 out of 5.0 by dmtru Looks good, fast shipping, but doesnt fit the Bonaire Durango 1600 sq ft model
Product arrived quickly and intact. Very good looking material. Other reviews said that this would fit Bonaire Durango (probably a different model) -- but did not fit mine Model # 6280035. I tried several different orientations. but the clips on the sides would not fully connect. My Durango model has a round grill (Directional Louver) that protrudes out and prevents the cover from being able to connect properly. I suppose I could have removed this.. but it seems to be too much of a hassle and I was worried Id break the louver clips.
Too bad I cant find any Bonaire interior covers for units after 2012. I returned this.

Rated 5.0 out of 5.0 by stan This product works better than I expected
I installed this swamper in an upstairs window of a 2 story house. It keeps both floors nice and cool. I do occasionally turn the fan to high during the heat of the day which is over 100 degrees at times. My neighbor is looking to replace his old swamp cooler. I will recommend that he buy this one.
