Which Shop Vac Is the Quietest?
The quietest shop vac on our list is the Makita VC4710 12-Gallon Wet/Dry Vacuum, working with a noise level of only 59 decibels.
Traditional shop vac noise levels are usually above 85 decibels, while household vacs are quieter with noise levels between 70-80 decibels. But with the right ultra-quiet shop vac, you can get the job done with much less noise.
With a unit operating below 70 decibels, you can have a normal conversation without having to shout. Between 70-80 decibels, you would need to raise your voice, and above 85 decibels you’d need to practically shout.
Quiet Shop Vac Buying Guide
One of the important factors to consider when purchasing a shop vac is to check for the power of the motor.
This way, you are sure that the vac you are purchasing would be able to do the job it’s intended for. A PHP rating of 5 is good enough so check for this.
The air power rating is also a factor to be considered. This rating tells you how effectively the vacuum cleaner can pick up objects, so the higher, the better.
Traditional shop vac noise levels in the garage or workplace are usually high. This is due to the type of motors they run on and their design.
However, long exposure to such noise is bad for your health, and its use pollutes the environment around you.
Always check the shop vac dB ratings. Levels of lower than 75 decibels are good enough and work efficiently and quietly.
The tank capacity should be such that it can serve you throughout your cleanup by accommodating as much debris as you suck.
The tank capacity that’s best for you depends on the type of job you’d need the unit for, and the size of the area you would be vacuum cleaning.
Different tasks require different types of filters. A foam sleeve would be more beneficial for wet use rather than dry use.
They are also filters that are great for use with different sizes of debris. It’s important to use the right size to avoid smaller particles from blowing out of the hose.
Vac accessories here include the hose and cord. Proper choice of both could make the cleanup process easier or more tedious.
Choose the right hose thickness as a hose that’s too thick would be difficult for you to handle while cleaning, and one that’s too thin will not give good results either.
The hose diameter affects the size of debris that you can suck in, so if you would be dealing with large debris, 2.5” would be good enough.
Also when picking a vacuum, go for one that has a long cord. This way you can clean at a distance with ease.
The blower function is essential especially if you have to clean some hard to reach corners. Most modern shop vacs have this feature and you should look out for it especially if you would be needing it.
Small or Big: Which Size Is Better for Shop Vacuum?
There is no one best size of a vacuum cleaner as the size you choose has its advantages and disadvantages too.
Big vacs have more powerful motors and can handle large spills and take care of heavy debris. This comes with much noise in the end and isn’t easy to move around.
Smaller vacs have smaller motors and so are fit for less demanding jobs. They are however quieter and easy to move around.
How to Make My Shop Vac Quieter
- Clean The Filters: with use, it’s advisable to wash the filters frequently or replace them if they are not washable. Even the quietest wet dry vacs can get noisy with dirty filters as they prevent free airflow during operation. Also clear out any clogs that may be present in the hose, to ensure free passage of air.
- Use A Sound Muffler: attaching a sound muffler to the exhaust of your vac could help reduce the noise coming from the machine. You could purchase one, or make one yourself.
- Build A Soundproof Box: building a soundproof box around the canister is the last resort if you still hear noise after muffling the exhaust. This is because the noise is likely from the canister itself due to the escape of air.
- Use Your Environment to Your Advantage: if you don’t want the noise from your vac to bother your friends and family, consider using it in open spaces. You could also keep it outside as you vacuum the room with the door and window closed as much as you can.
- Use A Longer Hose Attachment: some of the noise produced in shop vacuums are due to the turbulent airflow in the exhaust port. With the use of an additional vacuum hose to the port, you can move the end further away to reduce the noise.
- Use Variable Fan/Router Speed Controller: a variable fan/router is responsible for varying the power draw. The varying power draw affects suction power and also the noise produced. So if the task at hand isn’t demanding, reducing the fan speed will reduce the noise produced.
- Make Use of Hearing Protection: using hearing protection will protect you from most of the noise produced from the shop vac.
Why Did My Shop Vac Get Loud?
With continuous use, you may realize that your vac has become louder, and this is mostly due to obstruction to free airflow. So if your hose gets blocked, the unit would have to work harder, hence the noise.
The motor is another major reason for noise in your vac. As the motor causes the fan to turn to create suction, it produces sound.
This sound isn’t too much for some types of vacs due to the presence of brush bearings. Brush bearings function to deliver voltage to the motor, and to keep it aligned preventing contact with the stator.
So if the brush bearing breaks, the friction between the motor and stator will lead to loud noise.
Fine dust particles could also get into the motor bearings and other moving parts of the vac.
Its presence prevents smooth roll of the bearings and causes a squeal when the machine is in operation. It can be repaired or you could choose to change it altogether.
A dirty filter also creates noise when the unit is working. This is so because the vac has to work harder to create adequate suction.
In addition to this, if a fan breaks, it reduces suction and blocks the free flow of air thereby creating too much noise.
The need for a strong and high power vac in the workshop or garage doesn’t have to come at a noisy price.
That’s why we have these quiet shop vac reviews in 2021 to help with your choice and protect you from too much noise while you get the job done.
