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.

Had issue with RH sensor acting up prematurely. Sent email to customer service and within a day they responded and mailed a replacement sensor at no charge.

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.

Excellent product and excellent customer service from the seller. The fan was damaged in shipping but a quick email and they had a replacement part shipped in just a couple of hours

Got to me in hours at a good price. Easy to install and works great so far.

Upon receipt of the fan, I knew that I would have to do a little bit of retrofitting. Unfortunately, I didn't know how much retrofitting I needed to do to have the fan installed. My suggestions to the vendor would be to remove the brackets on the outside for a new construction fit. The brackets hinder the installation in that you need to remove the rivets that are holding the brackets for it to smoothly fit into the 9x9 opening that is required for clearance. Secondly, the support flanges that screw into either a joist or wooden cleat in the ceiling should be at least an inch wider. This is to support older construction where the drywall can be very brittle around the edges of the new cut opening. Thirdly, it is difficult to reinstall the fan into the housing. The set screws are very very difficult to screw back into the housing flanges. In conclusion, the fan is very very quiet for the space that it's in. The draw is excellent and is more than enough for a very small Powder Room. Conduit installation for venting is ample and ease of connectivity for electrical and ground is optimal. The ease of installation is lacking due to the metal support flanges being to shallow. Another inch of flange space from the main body of the chassis wood greatly increase the ease of installation. I had to spend a considerable amount of extra money in repair to my damaged drywall in order for the retrofit to be clean. Can someone from your sales team please contact me regarding this.

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.

One of the screws that holds the fan in doesn’t seem to catch and the cover doesn’t fit as tightly as I would like against the ceiling . I took a chance because it was recommended by consumer reports. I will buy a trusted name next time
