Review: Great product when modified (if your sensitive to noise) - The unit out of the box is actually great if you don't mind the bearing noises/minor rattle. The fans are loud so if you don't mind that they will be fine. While I don't mind a little white noise in the background, when it comes to my computer room with three workstations running it can get warm and I have all of my systems setup to run silently so I can work and have meetings. This unit has loud fans which to be fair push a lot of air and work great. Keeps the room significantly cooler when running. On that note I modified mine and changed out the fans with the be quiet 92mm fans that push about 33cfm. This is maybe half of what the originals put out but the difference in sound is unquestionable. Other than the sound of the movement of air they are completely silent and I just let them run at full speed. great "as is" if you need a room to be cooler or warmer but with modification if you want to cut down the noise it becomes amazing.
Review: 3 stars as is, 5 star if modified. - As is this is an OK floor booster that really helps move extra air into a room. It has a pair of high-flow 92mm computer fans inside that best I can tell move about 55CFM each. I opened the unit up and some google-fu on the model numbers of the fans revealed the chinese supplier's site with specs. Really about 55 CFM is about the max air flow you can get out of 92mm fan. Collectively they move ~100 CFM of air with no obstructions. So the unit pushes *quite* a bit more air than the competition's offerings, at least on paper. That said these things are not miracles. Pretty much any in-vent booster will change the room's temperatures by about 5 degrees at most. This one has the CFM's to do about that. Its actually moves MUCH more air than Susncourt's booster model that sits over the vent. On the pro side the housing is very nice, a nice obstructive brown color and fits neatly into my 4"x10" vents for a neat flush look. The cord could bother people but I have a plug near buy so it doesn't bother me. The temperature control is pretty standard thermostat And the unit has nifty LED lit lights and push-button controls. Trouble is the housing isn't the most brilliant design. The first big con is the intake grills. On the bottom side of the unit they molded in little grills that reduce the area for the intakes to about 40% of the area of a 90 mm circle. As other have noted, removing these will GREATLY enhance airflow upto that 100 CFM max. Since its on the side that inside the vent this will have no effect at all for safety noise. Fortunately if you don't care about your warranty they snip off effortlessly with some wire cutters. The second major con is the fans themselves. They work great, but they have a lot of buzzing bearing nose. So in addition to the white-nose whoosh of air there will be a grating buzzing coming from the fan's motors. However they are standard. The buzzing was about the same volume as a conversational voice, or a running shower for reference. If they noise is worth an ~5 degree change in the room's temperature is upto you. Now I purchased with the intent to modify. This product uses standard 12volt (2 pin) 92mm computer fans with molex mini connectors. This means that any one of the plethora of 92mm computer case fans will effortlessly fit inside the housing and wire up with a little doing. I ended up purchasing a pair of 44CFM Arctic brand "PWM" fans based on their reported lose noise, cheap price, and decent CFM. With a delicate touch I disassembled the housing (the top just clips on with plastic hook style clips, and removed the stock fans. This entire unit has no screws, its all plastic clips that need a firm but gentle touch to pry back to unclip the various parts without breaking anything. I then released the crimp on connecters out of the plastic plugs from the artic fans, did the same with with the stock fans after noting the polarity of the wiring (red is + black wire is - ). Now the attic fans are PWM as mentioned so they had 4 wires, but 2 of those wires are for reporting to the motherboard to control fan speeds. They are not necessary. So Artic was kind enough to label their 4 wires as PWM, RPM, +, and - in the specs for the fan. I released the terminals out of the 4 pin plug housing, took the 2 pin plug housings from this unit, and moved them, thus converting the artic fans to 2 pin 12v fans. I snipped off the extra wires that are no longer need (as they will never be installed in a computer) plugged in the new fans and closed up the whole unit. It now moves ~80CFM of air and is nearly silent. Now the only thing I can hear is the white noise of moving air, the motors and bearings are below my ability to hear them. Another reviewer here mentioned they used noctura brand fans. Noctura makes the nicest fans in the PC market, but the Artic fans were Seven dollars each compared to the $ twenty one each that the noctura's were. Thus I am not too worried if not matching up the amp-raiting on Artic fans burns them out and I need to replace them in 6 months or so. But yes I am happy with my purchase. I bought this for the housing and 12vot power system with the idea that I would be replacing the industrial grade, noisy fans. The fans suncourt picked would have been great for a server room where you could care less about noise, but pretty bad for a residential product.

## Questions & Answers

**Q: Can it be mounted on the ceiling?**
A: I mounted one on a ceiling vent but I had to drill two holes in it in order to attach it. Now it works just fine. For some reason it won’t let me attach a photo.

**Q: What's the difference between the ez8 and the eq2 other than appearance?**
A: size

**Q: Does this use a DC motor for the fan?  Watts it uses on each of the speeds is?**
A: No. AC connection only. Watts used per speed varries little. That all I've got for you.

**Q: Thank u rjm73 follow up q. if it is controlled by the blowers on/off air flow why would it have hot and cold settings?**
A: Don’t think this is worth the money.  Wound up putting a ducted fan in the pipe to this bathroom.  A lot more expensive but it moves a lot more air.

### ⭐⭐⭐⭐⭐ Life Changing--Buy This Now!!!
*by Z***R on August 10, 2020*

These were absolutely life changing. If your HVAC cannot effectively reach upstairs, buy these now. We had 20 days over 90 degrees this month, and have slept so comfortably. Last Summer it was 71 degrees on the main floor and 85 degrees upstairs. I have recommended these to my neighbors, and those who actually listened have all reported back the same life-changing stories... along with being upset they've dealt with sweltering heat all these years when there was such a simple, inexpensive and effective solution. Some reviews mention the noise, but I say "whatever." Low speed is pretty quiet and works plenty well, and you'll get used to it in a night if it even bothers you at all. I could see someone complaining about the noise at higher speeds, but we've never needed them, and frankly you'd get used to it anyway--it's basically just white noise, and some people pay stupid money for white noise machines. Some reviews also complain about the power cord... Are you kidding me? For the benefit of a cool, comfortable night's rest, I could not care less about the cord. By way of scenario... We're in a three-story townhouse community built in the 70's with zero insulation on the front and back walls and four inches of attic insulation. Everyone in the neighborhood melts upstairs in the Summer or opts to camp in their living rooms or basements. The usual advice is to spend a few grand to better insulate the attic and open up the walls to add insulation. We got one of these after a neighbor recommended, were amazed at the results, and the next day got three more for the rest of the upstairs registers. What a small price to pay for virtually unbelievable results vs. adding attic insulation and tearing open walls and ceilings to install a split HVAC system. Side note, while these worked insanely well and I could have stopped, I kept going. I added R-38 unfaced insulation to the attic along with Reflectix radiant barrier to the roof deck, which both definitely helped even more--the HVAC is operating more efficiently with slightly lower power bills than last Summer. The insulation was obvious, but it was the radiant barrier that surprised me. I very highly recommend the radiant barrier, which truly lives up to the marketing and reduces the actual temperature inside your attic. It was in the low 70's when I installed the radiant barrier, and my attic was like a sauna. It was in the high 80's when I then installed the attic insulation (poor planning I know), but here's the thing... the attic was actually cooler than when I installed the radiant barrier and the outside temperature had been in the 70's. I could not believe the effect of the radiant barrier, and recommend to everyone (depending on your latitude).
