Bathroom Exhaust Fan,90CFM,1.2 Sone, 4 Inch Duct | No Attic Access Needed,Very Quiet Ventilation Fan, Easy to Install Ceiling Mounted, White, ETL Certified

Came faster than was estimated. Perfect fit in existing hole of dead fan. Easy install and much quieter than the old one I had bought from local hardware store. Can still hear it but it is fairly faint. Quality feels good.

I am utterly blown away by the Tech Drive Super-Quiet fan! The name doesn't lie – I honestly can't believe how incredibly quiet it is while operating. It's almost silent, a complete game-changer compared to the roaring jet engine my old fan sounded like. But the real magic? The POWER! My daughter is notorious for taking epic, hour-long showers that usually leave our bathroom looking like a tropical rainforest, dripping with condensation and thick with steam. Yesterday, after one of her marathon sessions, I walked into the bathroom fully expecting the usual sauna conditions. I was met with... NOTHING. Not a single ounce of steam lingered in the air. The mirrors were crystal clear. The walls were completely dry. It was as if she hadn't even showered! This fan is an absolute beast at extracting moisture and air. If you're looking for a bathroom fan that is both unbelievably quiet and incredibly powerful, look no further. The Tech Drive Super-Quiet is a true marvel. It has completely solved our humidity issues and does so without making a peep. I am beyond impressed and wholeheartedly recommend this fan to anyone who wants a truly effective and silent ventilation solution.

Great match for my bathroom, look nite and modern and the most important - quite!!!

Because of the way the output duct connector attaches, you MUST have access to the space above/behind it., because it's impossible to just slide the unit into place through a correctly sized hole when this is attached. This is unfortunate because if it slid into place like some others this would be a very easy install from the front. This went into a small bathroom, roughly 5x10, where nominally a 50cfm unit would be sufficient; however, because there's no air gap under the door, i wanted a fan strong enough to pull air into the room through the only other route when the window's closed: the 5" furnace duct on the floor. That's a long trip for air to make from other rooms in the house, so I figured the extra oomph of a 90cfm fan would be helpful. In practice this was a good decision, the fan is very effective with the door closed without ever being too much. If the fan is on while showering, the room never gets humid and the mirrors never fog. If you wait and turn it on afterward, it takes maybe 5 to 7 minutes to fully clear the room of humidity and defog the mirrors. I don't know what 0.8 Sones is supposed to sound like, but it's pleasant enough in real life: there is absolutely no motor sound whatsoever, just a low, steady whoosh of air. Before installing I bench-tested it in the room by just running wires to an outlet, it and it was *extremely* quiet and clearly moved plenty of air. Once installed, the air resistance and slight back pressure of the ducting and the output vent cap I used increased the air noise somewhat, but it's still a rather pleasant, reassuring white-noise sound, and still not loud at all.

No where close to 0.8 stone. Not much louder than the tractor I replace. Consider labor and time spend I will give it 0 star

In 40 years installation never seen a squirrel cage fan move less air. The motor runs at low speed. DONT WASTE YOUR MONEY!

After purchasing two exhaust fans from Lowe’s that didn’t fit the opening in the ceiling, we came across this Tech Drive fan. It was almost half the cost of the fans from Lowe’s and was very easy and quick to install! As advertised, it is very quiet. So quiet, I questioned my husband on if it was even working properly. Our old exhaust fan has been broken for months and I like to take hot showers, but we knew it’s not good to let that moisture gather and build up. We can now shower with zero moisture fogging up the mirror or running down the wall! We have only had it installed for a week so I cannot comment on the longevity, but for the price it works great so far!

It is amazing just how quiet this fan really is! We are amazed! We bought this to replace a non-working fan in the bathroom of the house we just bought. We did hire a professional to install it, since there were some issues with the wall switches and we wanted to get them all checked out. He didn't seem to have any problem installing it except with the enlarging the hole in the ceiling to install it. Cutting out sheetrock overhead is a very messy job!

It was perfect ..so quiet
