Quiet HEPA Air Purifiers: 6 Low-Noise Models

When it comes to preventing allergies, removing airborne dust and just keeping the air you breathe clean in general, a HEPA air purifier is an essential tool. Many people, though, think that air purifiers are too noisy and will make it difficult for them to sleep, relax or focus. The idea that air purifiers are too loud is usually overblown, but there are several models made specifically to be quieter than their competitors. Here’s what you need to know about air purifier noise levels and six of our top picks for the best quiet HEPA air purifier.

 

  Are Air Purifiers Loud in General?

 

There’s a common misconception that air purifiers make a great deal of noise when running. This was somewhat true of older models, which typically used much less efficient fans than the options you’ll find in today’s market. Today, there are very few truly loud air purifiers, and most models are quiet enough that noise won’t become a serious problem.

 

With that said, there are still air purifiers that stand out as being quieter than others. These units are designed to be as close to silent as possible while still delivering great air quality. As a general rule, quiet air purifiers have multiple fan settings, allowing them to be turned down to lower volume levels when needed. With variable fan speeds, the air purifier can be set to a low level whenever you need some peace and quiet.

 

  What Rooms Need Quiet HEPA Air Purifiers?

 

While a low-noise purifier is always handy, there are certain settings that require one. Any space where work or study is done, for example, needs to be kept quiet. If your office or study space gets too loud, it can become difficult to concentrate on the tasks at hand. While some white noise can be helpful, a loud fan roaring in your ear will almost certainly make you less productive.

 

Quiet air purifiers are also essential in bedrooms. High noise levels can reduce your sleep quality, making you tired and less effective throughout the day. At the same time, clean air in your bedroom is extremely important, as you likely spend 7-8 hours each night in that room.

 

Other rooms can also benefit from low-noise air purification systems. Living rooms where you and your family come to spend time together, for instance, are likely not spaces in which you want a high ambient noise level. Similarly, kitchens or dining areas should be kept relatively quiet so that your meals can be eaten without a loud hum in the background.

 

It’s also worth noting that some people are more noise-sensitive than others. If you are relatively resilient to noise, you may only need a quiet purifier in your bedroom. If you are sensitive to volume, though, you may prefer getting a higher coverage air purifier to provide clean air throughout your entire home at low volume. This aspect of the selection process is mostly a matter of personal taste, so be sure to take your own noise sensitivity into account.

 

  Why Do Air Purifiers Make Noise?

 

Even though the noise level of modern air purifiers is usually overblown, it is a fact that all HEPA air purifiers do produce at least some noise while running. This is because purifiers use fans to force air through the filter material to clean it. While modern fans are much more efficient than their older counterparts, any moving fan blade will make a little bit of noise. So, the challenge for quiet air purifiers is to reduce that noise as much as possible, rather than to eliminate it altogether.

 

  Best Quiet HEPA Air Purifiers

 

To help you find the right unit for your needs, we’ve put together a list of six of our top quiet HEPA air purifiers. While all of these units are quieter than average, they also have other great features that make them stand out on their own merits as purifiers.

  EnviroKlenz

  Made for optimum filtering of both particles and gases, the EnviroKlenz air purifier is a unit that does well for almost any application. In addition to excellent filtration capabilities, this model can operate at extremely low volume levels on its lower settings. On low, this unit is quieter than a fan, while on its unique Whisp-Air setting it produces no detectable increase to ambient noise levels.

  •   HEPA filtration
  •   Patented VOC filtration system
  •   Dial control

While we typically recommend the EnviroKlenz for removing gases and odors, it is also an excellent HEPA purifier. Whether you need protection from VOCs or everyday particles, this air purifier is a great option.

 

  Amaircare 3000 HEPA

  When it comes to quiet HEPA air purifiers, the Amaircare 3000 HEPA is a unit that can’t be ignored. With both a quiet low setting and a special silent mode, this air purifier can keep delivering clean air at very low noise levels. Thanks to its ability to cover up to 1,800 square feet, the 3000 HEPA is also a great choice for medium-sized homes and large apartments. Key features of this model include:

  Airpura R600

  Last but certainly not least on our list is the Airpura R600, an all-purpose air purifier featuring both HEPA and carbon filters. This model runs at quite minimal volumes when used on its low setting, making it a good option for spaces where noise needs to be cut out. Key features of this model include:

 

  •   2,000 square foot coverage
  •   HEPA and carbon filtration
  •   Targets both gases and particles, great for allergy and asthma sufferers

 

While the R600 is a general use purifier, it does target both gases and particles extremely well. The HEPA filter in this unit uses a total of 40 feet of material, while the carbon drum filter includes 18 pounds of activated carbon. Between these two, the R600 is a great choice for practically any common contaminant.

 

  Is One Purifier Better Than the Others?

 

In terms of sheer noise reduction, the Rabbit Air Minus A2 is likely the best model on this list, given the overall volume range in which it operates. An argument can also be made for the EnviroKlenz and Amaircare 3000 HEPA, as each has a made in which it operates effectively silently. However, each of the air purifiers listed above has features that make it a good choice, which is why we created a list instead of recommending a single product. At the end of the day, it’s about which one is the best for you, rather than which one is the best overall.

 

  How to Pick the Best Model for Your Needs

 

Picking out a quiet air purifier is about more than just considering noise levels. You also need to think about the size of your space and the features you want your purifier to have. If you try to decide based on noise levels alone, you’ll likely miss out on other important aspects of the air purifier selection process.

 

It’s also important to keep your budget in mind. Air purifiers come in at many different price points, but there are great options available at every level. Whether you need to keep your spending in check or not, there’s an air purifier out there that will suit your needs.

 

  Should You Keep Your Air Purifier on Low All the Time?

 

As stated above, the quietest air purifiers are generally those that have low fan settings as an option. This brings up the interesting question of whether you should leave your purifier on low at all times. While you could take this approach, a better solution is to set the unit on a higher setting when quiet isn’t essential. For example, you might decide to turn your air purifier up to a higher fan speed during the day while you’re at work, then turn it back down when you come home. This saves you listening to ambient noise while allowing the unit to clean the air as thoroughly as possible.

 

This is another area in which the Rabbit Air Minus A2 stands out. Because of its automatic night mode, you can turn your air purifier to a low setting simply by turning out the lights. This lets the Minus A2 run optimally throughout the day, then put itself into a quieter maintenance mode at night. If you mostly need quiet during the night, this makes the A2 a nearly perfect option.
