Why do air purifiers make so much noise?

Home air purifiers are an environmentally-friendly way of reducing indoor air pollution, but they make some noise as well. So, do they make noise when they work? And how loud is the noise from your purifier?

Some air purifiers are designed to be quieter than others. Mostly though, home air filters will produce a hum or a low background drone as they work. The sound can vary depending on how much dust and dirt is in the filter's intake area and whether it uses positive or negative ions for its function. You should also consider the size of your room, since larger rooms will need more powerful machines that produce louder sounds overall.

How Much Noise Are Air Purifiers Making?

Air purifiers make different sounds depending on the kind of machine they are. But, with any air purifier, you may hear the background noise that it makes more than once during its normal running time. For example, dust collectors are louder than fan-only machines.

Not every air filter needs to be powerful enough to produce a loud hum for its function to be effective.

Why is my air purifier so loud?

Not all air purifiers are designed to be large industrial-sized units. Some of the smaller models with lower power will make a louder noise. Not every air filter needs to be powerful enough to produce a loud hum for its function to be effective.

A device's noise level is affected by the number and size of its fans, its filtration capacity, and the speed at which it operates. Some appliances may have been designed for small rooms or areas with limited space requirements and can be super quite while others are meant for open spaces that need big powerful fans for optimal performance, thus making them louder than some other household air cleaners.

How do I reduce air purifier noise?

The noise made by an Air Purifier can be make more quiet by:

1. Check the noise level

Before you purchase an air cleaner, check out how loud it is to make sure that you can take proper measure of it in your home before you buy.

2. Use a fan to soften the sound of air purifiers

A fan placed strategically near the filter will draw the noise from the appliance and fill your room with natural air, making it a lot quieter than if there's no fan nearby. (This method should be used only as a last resort, as it may draw dust around your filter.)

3. Close the door when using your air purifier

When you use an air purifier, you might want to install a door in between it and the rest of your living space to prevent noise from escaping. This will also make it harder for the air cleaner to suck dust in, reducing your noise level by another 10 dB.

4. Keep an eye on the noise level with a Sound Level Meter

A sound level meter is a device used for measuring sound intensity and is also called decibel (dB). Depending on the type of unit that you have, you can buy various air purifiers that come with their own sound level meters for accurate readings at home.

Which air purifier is the quietest?

Manufacturer of Air Purifiers may quote their noise level for in-room use.

The quietest Air Purifier runs at about 23 – 50 dB which is very quiet, the noisiest runs at 50-70 dB which can be quiet loud. Our list of Air Purifiers on this page give some of the most quiet ones available

Do air purifiers need to be on all the time?

Air Purifier do not need to be left on all the time, it is best to use them when you are in the room where they are.

Air purifiers work by pulling the ambient air into their filter where it is cleaned and then releasing that air back into the room. The louder the sound of the air purifier, the more it will produce a cyclic noise pattern in its operation. This cyclic noise pattern is similar to an airplane that comes in for a landing and ascends again, it will approach and recede from your ears at specific intervals. If you are sensitive to this kind of noise you should consider one of our quieter models or simply turn off your appliance when not using it.

How long does it take for an air purifier to clean a room?

30 mins to 4 hours depending on the size of your room and if it is dusty or not.

Conclusion

There are lots of factors that affect the noise generated by the air purifier. These include the number and size of fans, the power usage, filtering capacity, speed and volume of air being moved around by the fan blades and even cyclic noise patterns due to oscillating fans. A well-maintained machine will run quietly for many years. The sound level may also increase as time passes because dusty rooms require more cleaning, which can lead to clogs in filters that cause noises.

Some people find a few decibels extra noise while others need a completely silent vacuum cleaner for their comfort.

Experience : Hi, I am Nick, I purchased an Air Purifier, and Humidifier for my home, and I want to share the benefits of owning both appliances.

I know that there are some advantages to having an air purifier alone, but I wanted to tell you about the ones that I have personally found when owning one with a humidifier. For instance, not only does it help keep the air in your home cleaner. But it also keeps your skin clean! It is important for people with sensitive skin like myself because they can experience dryness if their skin isn't properly hydrated.
