How To Choose The Best Quiet Portable Air Compressor?
Determine Your Power Needs
No matter how silent a portable air compressor is, it definitely is junk if not meeting your power needs. Therefore, determine how much power you need your air compressor to produce by considering:
- The size of your air tools
- How are these tools used - working in short bursts or continuous use?
- How is the portable air compressor going to be used – to supplement a larger unit or to be your primary compressor?
Pro tips: Utilizing the CFM ratings on your air tools will help you determine your power needs easily and accurately.
Where Can The Portable Air Compressor Be Used?
Finding the answer to that question helps you easily judge the noise rating of your portable air compressor.
In detail, the noise isolation of a model used outdoors and separated from your neighbors and your house will not be as a huge concern as that of a model used indoors and close to your family’s living quarters or neighbors.
You should also consider if you’re willing to wear ear protection when working with your air compressor.
If yes, then a model with a 60-80 decibels’ noise rating is fine. If not, then choose a quieter model (around 50 to under 60 decibels).
Noise Ratings
We think the noise rating ranges from 50 to 80 decibels are “quiet” for portable air compressors.
Why 80 decibels? It’s because this is the threshold for utilizing ear protection.
According to the models that our team tested, powerful 2.5-5 CFM portable units make noise close to 80 decibels while smaller 0.5-2.5 CFM portable units make noise from 50-60 decibels.
Important notes: Every 10 decibels added roughly double the noise level.
Noise-Dampening Features
When considering a given quiet portable air compressor, you should look for specific design features available that soften the operation noise. Here are some typical examples:
- Oil lubrication
- Rubber noise isolation components on control dials or hand grips
- Mufflers which are commonly found on higher-end air compressors

FAQs
What does a bad air compressor sound like?
A bad air compressor produces loud, high-pitched grinding or squealing sound.
Why is my compressor so loud?
If you find your compressor runs loudly, the noise might be caused by the friction of metal sliding or hitting against metal inside the unit. A basic rule of thumb is the more moving parts inside an air compressor, the noisier it is while operating.
How can I make my air compressor quieter?
There are several ways to make an air compressor quieter:
- Cover it with a soundproof blanket
- Add a soundproof box to it
- Install sound padding on the compressor walls
- Place the machine outside and far away from your living area
- Lubricate the bearings
- Install rubber grommets on the machine
Are oiled air compressors quieter?
Yes, they are. The more well-lubricated the air compressor bearings, the more quietly it runs.
How often should you change air compressor oil?
You should change your air compressor oil every 4,000 operating hours.
