A breath of fresh air Bonaire BAP336 I have been wanting an air exchanger for my heating system but they are just too expensive. I was overjoyed when I found this window mount air exchanger. The installation was easy. The mounting system accomodates many different window sizes, but you must "measure twice, cut once". The adapters are snap-offs and there is no going back if you goof. The fan is smooth but a little loud. However the effect is the same as one of those nature sounds white noise generators. I like that it has a heat balancer function so the fresh air doesn't force my heating system to run any extra. I have not noticed a significant increase in my electric bills either.
The bottom line is the quality of my sleep has improved dramatically since I started use the Bionaire BAP336 and it has continued since. I currently only have the one in the bedroom but I am going to get a second one for the downstairs and run it all the time.
Great invention!...more info
