SNP100 | 100 CFM | 0.8 Sone | No Attic Access Required Bathroom Ventilation Exhaust Extractor Fan

Pros:First off I would like to give a shout out to Amanda on the customer service team. I recieved a damage grill cover and she took care of me. The replacement grill arrived three days later after I contacted the service team. Also they have replacement parts on the KAZE website you can order in case issues arise in the future. The unit was fairly straight forward to install even though I had 24" o.c joist. I just modified the included hangers to make them long enough to span from joist to joist. These units are also Energy Star and HVI certified. The unit passes the tissue test as well. This is just a simple test to make sure it applies a negative pressure to the room to facilitate evacuating the humid or stinky air in the room. After a hot shower my glasses are not fogged up either. It takes about 15-20 minutes to clear my bathrooms of humid air. I did test the sound inside and outside the two bathooms I installed them in using the NIOSH sound meter app. The first is a master bath connected to the bedroom which averaged 36.8 decibles (~1.8 scones) outside the bathroom approximately 10 feet away from the closed door. The second is a hallway bath which averaged 36.1 decibles (~1.7 scones) 10 feet away from the closed door. Background noise was about 30 decibles. Granted this is not a scientific test but a real world example of what you might see.Negatives:I don't know what test standard is used to measure the sound level of bath exhaust fans, but I was not getting anywhere near 0.8 scones inside or outside the bathroom. Inside the bathrooms scone levels were on average 52.2 decibels (~5 scones) for the hallway bath and 61.4 decibles (~10 scones) for the master bath. Bathroom size, duct work type (insulated or noninsulated), and duct lenth do affect noise generation though. Both of my bathrooms are on the smaller size. The hallway bath is 50 square feet and the master bath is about 30 square feet. A 100 cfm bath exhaust fan is typically sized for a 100 square foot bathroom. I imagine the noise would be much more diluted in larger bathrooms in terms of square footage or volume (i.e. high ceilings). KAZE does recommend insulated duct be used in their installation instructions. It is code in most places and tends to dampen the noise as well as prevent moist air from condensing back down your ductwork and into your bathroom. I will mention the rise of the duct work in my master bath is only about 2 foot to the roof termiation cap. On really windy days I can hear the backdraft open and close. This does not occur in our hallway bath which has approximately a 5 foot rise to the roof termination cap. Again, my tests are not scientific. I imagine these units are probably tested in a standardized sound proof booth that can eliminate background noise. The noise does not bother me but I know that is a problem for others.Verdict:I would definately recommend purchasing this product. The price, customer serivce, and functionality of these bath fans sold me. Yes, I had to make modifications during installation but that is what I expect with any project. You can anticipate much more noise dilution than what I measured if your bathrooms are larger than my small ones.Update: 01-01-2024Please make sure you do not over tighten your ductwork to the duct adapter. The adapter is plastic and over tightening it will deform its shape and not allow the flapper to open when the unit is turned on. I noticed one of my bathrooms was taking forever to reduce humidity so I investigated and this was what I found. After this correction it only takes about 10 minutes to noticeably reduce humidity. I also noticed less noise, almost nonexistent most days, from my roof termination vent’s too on windy days.

I assume it was a good item, I ordered 2, one was delivered damaged, the other was okay. problem is, they were bigger than the tiny spot I had to install them in.

I’m not sure why consumer reports thought this was so great. It’s not That loud, but it’s not as quiet as the Panasonic fan in the other bathroom. If I had to buy again I’d probably get the Panasonic fan.

Superior performance to the unit we previously had. Reduces the humidity & gives us a dryer master bathroom shower after use.

Excellent fan and light. Easy to install with good instructions. Works great. Very quiet fan and the light is excellent.

Moves a lot of air, which is the most important feature for a bath with shower. But I also bought because of the low noise claim. Mine is not that quiet however - almost a metallic type of noise. Installing in tight space was not easy as external metal box changed a bit when installed, which meant screws to insert/attach blower unit were difficult to line up and get threaded. I would not buy this model again.

Gregg from MN.Bought 3 kaze snp-100.Install went slick like they said it would!Had 1 fan blower motor making strange noise. E-mailed customer service, they got back to me in MINUTES on aSunday!.Make a long story short, Ihad a replacement in 6 days!!! I didn't have to return anything.Very happy with fans, extremely happy with customer service!!!! Would recommend to anyone.

Build quality is good. Noise quality mentioned is not correct. It makes lot of noise. This was not expected with sone level of 0.8. Humidity Sensing doesn’t seem to work. After shower, the fan is in but moisture is not reduced. It takes me to open the window or keep bathroom door open to get moisture out. Wanted to return but spend 200$ for installation. Don’t want to spend another installation cost.
