User questions & answers

Question:	Is there a way to attatch a filter to this system so the dust being removed from the work area is being filtered before is released outside
Answer:	This positively uses 13 amps. that is about 1300 watts. 120 volt wall outlet. it really blows like a son of a bitch too. I am very, very impressed. Plastic blades . Sounds like 3600 rpm. Both speeds sound like no change. it is about 20 times stronger air than a silly walmart 19. dollar square fan. No joke. steve
Question:	Does ir work for automotive exhaust in my garage
Answer:	Not sure what the term “work” is referring to. The fan is made to move the cubic measure of air and pass through a simple charcoal filter mainly for soldering fumes & related. As far as operating near a hot plate it is not intended to use as a cooking exhaust type fan. A box fan in an open kitchen window when cooking may be a better option since it will move more air and should fit in a small open window based on size (usually around 20x20”). I’m only guessing what use you are applying a fan for. Please be careful when cooking inside on a counter top for fire hazard. Have working smoke detectors and fresh batteries never leave hot plate on or unattended. Be safe.
Question:	Can you run this fan 24x7? Need to use it to extract heat from a room 24x7. Thanks
Answer:	I bought this for my kitchen for the same reason. I have only used it once but it seemed to help. The fan is not as strong as what you would find in a typical kitchen stove hood.
Question:	Does anyone know how much power this uses (Kw/h
Answer:	This product can not. Cigar smoke is way too potent. I blow small pipe hits through mine and it just barely does the job. Try a Smoke Buddy that should work if you really need it.

User questions & answers

Question:	Can you use the fan without the thermostat feature? I don't want it going on and off all night long
Answer:	I think the other replies were with older models? I just purchased this model and there's no issue with opting out of the thermostat feature. As noted in the instructions, to get to continous air flow, you just keep clicking the button through the modes (first you click throught the various thermostat temperatures, and then you get to "high" or "low" as options. If you click high or low either one will stay on continously. Both options are extremely quiet. It sounds like the person who had a louid nose on the low setting had a defective fan.
Question:	I want to use this in a stand-alone one room dance studio with only one window. If it's very hot outside, will this really keep it cool inside
Answer:	It’s not an AC unit so it will only be as cool (or slightly less hot) as the air from the source. That being said you could use this fan on Exhaust to suck hot air out and use a tower fan to create a breeze in the room. But to cool a room on a 90+ degree day, I’d recommend a window AC. This fan will circulate air tho, so it’s not a bad place to start.
Question:	I need the CFM and decibel (noise) ratings on this fan. These are my two most crucial criteria, but no one shows them
Answer:	This is our second window fan. I don't remember what brand/model etc our first fan was, but the CFM WAS WAY higher than this Holmes fan. My assumption is by lowering the maximum fan speed & thus drastically lower the CFM, they can advertise the fan as being quieter and using less energy. ***We have used this fan for 2 years and we DO NOT recommend it if you are looking for a high CFM (volume) fan***
Question:	Hey all, how are your fans holding up with moderate to heavy use? over 2yrs? 3yrs? more? let me know, thanks
Answer:	I’ve been using an older version of this fan for about 20, yup, 20 years. I use it in a garage studio. Sometimes it runs for months 24/7. It’s slowing down, tons of dirt and mysterious things on it. While it is exhaling i spray wd30 on it till it speeds up again, lol. I have absolutely punished this fan. But like I said, I run it all year, summer and winter. One side died about 4 years ago, but the other is running as we speak. The reason I saw this is because I was looking to see if they still made it. Yay they do; and it is very quiet. Next paycheck I’m getting a new one. I love the intake exhaust function,brilliant! So happy they’re still available. Can’t go wrong, and not a lot of money.

User questions & answers

Question:	Will this work for chemical fumes from glues
Answer:	Hello Yes this absorber fan can work for spray paint like model kit painting jobs but you will need to purchase Fiberglass paint arrestor pads filters and cut them into shape to properly capture the spray paint fumes.
Question:	How does it work with Tig welding
Answer:	Yes but you have to make one. I used blue foam insulation board . I cut a circle in it the diameter of the hose and then taped a filter on if from a house heater...HVAC filter. The fans are amazing. I own two of them for my painting company. But on high they are a little on the loud side. Very solid construction.
Question:	Does this work for cigar smoke
Answer:	Yes, is powerful exhaust fan
Question:	Has anyone used this with spray paint indoors to reduce the fumes
Answer:	I have ran mine 24/7 for about 3wks plus adding about 110°f heat to help dehydrate water from a refrigeration system chiller. No problems and is still working! This is a solid built item.

Installation Precautions:

1. Installation>> You can purchase 1 or more as needed, connect it in the middle or both ends of the pipe, or install it on the wall, DIY your own air circulation system.

2. Space requirements >> Do not vent in one direction in a closed environment. The installation environment requires intake and exhaust to ensure air circulation and to avoid air pressure differences due to excessive air flow.

3. About Wiring >> Each exhaust fan has a 40cm standard cable, which is convenient for you to connect the circuit. You can configure the plug or power switch according to your needs.

4. About noise >> 30-40 dB, if you are installing in the bedroom, please try to stay away from your bed.

5. About wind speed >> If you think that the air volume is too large, you can equip him with a speed control switch to control the air volume, or you think that the air volume is not enough, you can add more fans.

User questions & answers

Question:	If the power goes out, will this fan come back on on its own when the power is restored, or so you have to turn it back on yourself
Answer:	I think the other replies were with older models? I just purchased this model and there's no issue with opting out of the thermostat feature.

This fan will circulate air tho, so it’s not a bad place to start.
Question:	Just received and only one fan is spinning, is it defective? I tried switching from exhaust to intake, left blade doesnt spin at all
Answer:	This is our second window fan. I don't remember what brand/model etc our first fan was, but the CFM WAS WAY higher than this Holmes fan. My assumption is by lowering the maximum fan speed & thus drastically lower the CFM, they can advertise the fan as being quieter and using less energy. ***We have used this fan for 2 years and we DO NOT recommend it if you are looking for a high CFM (volume) fan***
Question:	Our window slides from the side. Can this fan be place vertically instead and then close the window against the long side of it to secure it
Answer:	I’ve been using an older version of this fan for about 20, yup, 20 years. I use it in a garage studio. Sometimes it runs for months 24/7. It’s slowing down, tons of dirt and mysterious things on it. While it is exhaling i spray wd30 on it till it speeds up again, lol. I have absolutely punished this fan.

Question:	Can you use the fan without the thermostat feature? I don't want it going on and off all night long
Answer:	The app. There are 2 place I have found that you can turn the detection off. On the live video page and also in the settings
Question:	I want to use this in a stand-alone one room dance studio with only one window. If it's very hot outside, will this really keep it cool inside
Answer:	The actual battery life of the doorbell depends on the number of wakeups and accesses per day and of course, the recording time will also matter. Usually, in standby mode, it can last for over 3 months(10 times wake-up per day). And it can wake up at least 1000 times when it is fully charged. Besides, as this product uses PIR thermal detection, there are two triggering principles: 1) when there is a temperature difference, 2) when there is a moving object. So we recommend not to place the doorbell too close to the street or the crowds, in order to avoid unnecessary wake-ups due to the temperature differences caused by the vehicles or personnel passing. *Please install the doorbell camera in a place that is away from direct sunlight or street lights for better performance.
Question:	I need the CFM and decibel (noise) ratings on this fan. These are my two most crucial criteria, but no one shows them
Answer:	This is app driven, not pc based---unless of course you have an app driven tablet or a two in one device that can access Google Play services. Check for iTunes compatability.
Question:	Hey all, how are your fans holding up with moderate to heavy use? over 2yrs? 3yrs? more? let me know, thanks
Answer:	There is a toolkit pack including all necessities in the package for you. A 3M double-sided tape is included as well.

User questions & answers

Question:	This fan runs on ac or dc power
Answer:	110 ac
Question:	Why is it when I went to pay for the 4” inline fan that was listed at for $25. 98 it went up to $35. Free shipping items $25 or more... Lies
Answer:	Because Amazon doesn't like you, obviously....lmao, nah never count on free shipping unless you have Amazon Prime, and the item has the word Prime in blue with a check mark...otherwise, expect a charge for shipping regardless of the item's description or Amazon's cost analysis. These items are oftenly sold by third party vendors, and Amazon can't always accurately estimate shipping costs for them.
Question:	Can you attach a variable speed controller to this
Answer:	You can, however, with just 200 CFM of air movement you may want to just keep it on full. The motor will make more humming noise if you use a speed controller to decrease speed. I found it makes less noise on full than it does if you decrease the speed which increases motor hum noise considerably.
Question:	Is my fan defective? For such a small fan it is extremely loud
Answer:	Use light weight clipper oil on the moter behind fan blades, also use tape to hold to pieces together after twisting back together. I own three need to add oil to all. All have been running non stop for over 6 months.
