Air KingBFQ110 Ceiling Mounted Snap-in Installation 100 CFM Bathroom Exhaust Fans, Medium, White

OK....I was somewhat skeptical of the low price for this fan but I took the plunge and bought the 100 CFM model. It arrived today and I installed it today. The installation wasn't easy but not because of the fan. My attic is hot and I had to crawl on the support beams so I wouldn't fall through the drywall. Total time to take out the old crappy unit and install this new fan was about two hours. The fan came with just about everything needed to install it but it does not come with mounting screws. So make sure you have some high quality wood screws before you start this project or use nails. I had to use a 4 inch to 3 inch adapter on this fan but I knew that before purchase so make sure you have the correct exhaust duct size before you climb into your attic. I highly suggest anyone installing bathroom vent fans use the shiny Foil Tape used in HVAC systems. It's cheap and great for connecting the exhaust ducting to the fan exhaust. The foil tape will prevent any leakage from the exhaust duct connection if used correctly. You want to make sure there is ZERO leakage into your attic from any and all bathroom exhaust fans. I replaced my entire roof yesterday because of a leaking bathroom exhaust fan. The fan leaked moisture slowly but surely into the attic and cause a large section to grow mold. You get the picture. After installing the fan I sealed the gaps in the drywall so no air is leaking into or out of the attic from the bathroom below. I used the Foil Tape for this. It worked great. A suggestion for anyone installing this unit: I suggest you connect the exhaust ducting to the exhaust of the fan BEFORE mounting the fan unit on the fan mount. Why? Because the exhaust port if snug against the support beam the mounting bracket is connected to. There is very little room to seal the connection with Foil Tape or anything else if the fan is mounted in it's bracket before connecting the exhaust ducting. Testing the exhaust fan: I turned it on and was surprised that this fan is actually quieter than the fan it replaced (original with house). I used a sound meter and tested the fan noise of this fan: 69 dB. Not bad. The original fan was half the air flow (50 CFM) and it was noisy at 80 dB. Next test was the "smoke test": With the fan running I opened a can of "smoke" two feet below the fan intake. The smoke was sucked in the fan quickly. So all in all this is a great deal to me. It's relatively quiet, pushes 100 CFM (with a 4 inch exhaust duct) and is very inexpensive compared to other brands. What more can you ask for at this price? I'm ordering another one now for the other upstairs bathroom.

We purchased this Air King fan to replace the fan and motor of our 19 year old fan. Once I cleaned and disassembled our existing fan we realized it was not possible to remove the old housing without making it a drywall and ceiling paint repair job due to the "clip in" feature. So we cleaned out the housing, removed the fan from the new one and used the old screws to install it into our old housing. We also used the new cover as the old one was faded. It works great- and now we can hear just how our old one had really given up. This one sounds stronger and a little louder- not a problem bc it works and was super easy to install.

Installed in combination with a Leviton Humidity switch for my finished basementTo be frank, it's very plastic and doesnt feel solid and it was pretty noisy and rattly at first, I realized that some of the motor screws were loose, once fixed it fixed the rattle and helped with the noise but it's still too loud, especially compared to the Panasonic Whisper in-line air extractor in my bathroom.But it works and it works well, has made a massive difference in the air quality in the basement and for the price its still a good buy, it's not really for habitable spaces and there's no way I'd put this in my bathroom but other people with little sensitive hearing probably would be indifferent ?

Worked great and a direct fit very little effort needed to install

I had to remove an old exhaust fan in my bathroom and replace it. I bought this fan based on the reviews that I read. It was fairly easy to install. I removed the old fan with a small crow bar and pliers, and cut the drywall in the ceiling to accommodate this unit. The metal holding bracket attaches to the ceiling joist in four places, I used screws.I had to cut the hole a bit larger than I hoped because of the metal bracket and the protruding 4" exhaust vent. The unit seems to move air well in my 80' square foot bathroom. My problem though is noise. This fan is pretty loud, in fact I can hear it coming up my steps outside of my bathroom.I didn't expect perfect quiet at this price, but I hope it would be a bit quieter. Otherwise the materials and packaging are good.

This exhaust fan works great. I have a 5 x 11 full bathroom, this fan works great and its not all that loud. The install was easy since it just clicks in place after you install the bracket. There is no need to go into the crawl space to install.My local big box stores had similar fans but there price was a lot more.

Good product
