The 8 Best Quietest Air Purifiers in 2021
1. LEVOIT LV-H132
The LEVOIT LV-H132 comes with a 3-stage filtration system that successfully captures all airborne particles because it utilizes a pre-filter, a high-quality activated carbon filter, and a true HEPA filter.
This mighty combination ensures that all allergens, VOCs, dust particles, odors, smoke, pet dander, or pet hair are removed completely from the air to give you excellent air purification.
And the best part is that it does so at only 25 dB! This is one of the lowest numbers you can find on the market, especially of a quiet air purifier of this quality and efficiency. You can definitely have an uninterrupted, good night’s sleep with this unit.
Moreover, there’s an indicator that works on reminding you to change your air filters, which would be around once every 6 to 8 months.
Finally, the LEVOIT LV-H132 comes with a night light that further qualifies it to be a nighttime quiet air purifier. This light comes with two levels of brightness that you can adjust according to your needs. Not to mention, the unit is FCC and CARB-certified as well as ETL-listed.
However, it’s worth mentioning that its effectiveness with dust stops at relatively larger particles, so if your main concern is that, or if you suffer badly from a condition, you might want to opt for an air purifier with a higher ability to catch dust particles.
- The quietest operation on the market
- Space-saving and compact design
- 2-level brightness night light
- FCC and CARB-certified
- 4 ACH
- Filter replacements can be a little costly
- Doesn’t get rid of all dust
2. PARTU Air Purifier
With the ability to clean the air in a room of 107 square feet or less, this PARTU HEPA air purifier operates at a noise level of only 38 dB at the lowest setting and 59 dB at the highest, which is a pretty good range.
You can also adjust the fan to one of the available settings to manage the noise level. However, it’s worth mentioning that the unit does begin making some ticking noises after a couple of months.
Like the LEVOIT LV-132, it comes with a 3-stage filtration system that comprises a pre-filter, a true HEPA filter, and an activated carbon filter. That’s why it’s capable of capturing all pet dander, smoke, odors, pollen, dust, and pretty much anything under the 0.3-micron mark or PM 2.5 air pollution.
Moreover, the PARTU comes with a lockset on which you can press 3 seconds to activate, which consequently deactivates touch mode to avoid any mishaps.
Replacing the filters won’t cost a lot and isn’t a frequent event, though finding the filters is a bit of a hassle. Also, below the outlet of the air purifier, you’ll find a sponge on which you can drop some essential oil to give a nice fragrance to the room.
Finally, safety is ensured with this air purifier as it’s ozone-free and has the approval of FCC, ETL, and CARB.
- Strong and reliable performance, especially for the size
- Quiet operation
- Works well for the majority of pets
- Comes with an option for fragrances
- Doesn’t work as effectively for smoke
- Prone to making more noise after a while of use

Choosing an Air Purifier
It’s not easy to find an air purifier that does its job effectively without disturbing everyone in the room, but it isn’t impossible with proper research. If you’re looking for the best quiet air purifiers, make sure to check off the following aspects while you’re considering your options.
Perhaps the most important components of your air purifier are the filters. Typically, your air purifier would come with an activated carbon filter and a HEPA filter. Some use a pre-filter, UV-C technology, or ionization, which we will go over a bit later.
An activated carbon filter is the one that takes care of odors, which is one of the most vital functionalities of air purifiers. Also, a carbon filter is the one responsible for trapping the VOCs (Volatile Organic Compounds) that even a true HEPA filter fails to capture.
With most activated carbon filters, you’ll be getting treated carbon, which comes with some additives that enable it to become more adsorptive or reactive in order to fortify its ability to eliminate air pollutants. However, it’s more detectable than a carbon filter that uses untreated carbon.
As for HEPA filters, they’re the component responsible for capturing around 99.97% of airborne particles that cause air pollution. HEPA filters are capable of getting rid of pet dander or pet hair, allergens, bacteria, mold spores, pollen, and more.
Some models come with ionization power, which means that they send negative ions that stick to dust and other airborne particles, which get sucked into the air purifier by the attraction force of the positive plate installed on the inside.
You could also find some units with UV lights, and these ones work on killing bacteria and germs in the air, which provides sterilization along with air purification. They also offer good protection against cases of flu and colds as well as alleviate symptoms of allergy and asthma.
However, be careful with the latter two, as they are likely to produce ozone, which is said to damage lung tissues. That’s why they aren’t approved by federal government agencies and aren’t endorsed by any professionals thus far.
For a quiet air purifier, you need a unit whose fan speed settings are all quiet, even the highest one. Still, the tougher the fan is, the noisier it would naturally be, and that’s why you want an air purifier that strikes a balance between both. Alternatively, you can get one with both but on a higher budget.
Clean Air Delivery Rate (CADR) and Air Changes per Hour (ACH)
The CADR number shows the clean air delivery rate that your air purifier is capable of. For air purifiers to work effectively, their CADR has to be two-thirds of the room size in which they will be placed. So, if your room is 150 square feet in size, you need an air purifier of 100 CADR.
The ACH (Air Changes per Hour) is another number you should be on the lookout for. It indicates how regularly you’ll be getting clean air around the room, and a good air purifier would give you 4 or 5 changes per hour.
One of the most tedious things about having an air purifier is taking care of its maintenance, and that’s why you should opt for a unit that doesn’t require a filter replacement too frequently and comes with a filter replacement indicator to remind you to buy and install your replacement filters.
Speaking of which, a unit whose filters don’t cost an arm and a leg to replace would definitely be a better option and investment in the long run, even if it has a higher upfront price.
Air Quality Sensor
An air purifier that comes with automated settings would spare you a lot of time and effort. The most important of which are the air quality sensors that detect the quality of air and adjust the fan speeds accordingly.
Not only does that help conserve power, but it also ensures that the air purifier would be running on the quietest option possible at all times.
Since you’re looking for the quietest air purifiers, you’re surely concerned with the level of noise, measured in decibel (dB). Noise levels have to do with the size of air purifiers as well as the technology integrated, but the average is between 30 and 55 dB.
If you’re looking for a quiet one, you shouldn’t go higher than 55 dB, but you can very well find ones that run at 23 or 25 dB. However, for effective air purification, especially for rooms of a relatively bigger size, you can’t find anything lower than that.
Now that we’re done with our reviews on the best quietest air purifiers on the market, we hope you’ve finalized a purchasing decision.
If you’re looking for a unit that combines a little bit of everything, the LEVOIT LV-H132 would be an excellent choice. With a 3-stage filtration system, quiet operation, and a night light with two brightness settings, this unit was designed to give you a good night’s rest.
However, replacing its filters could be a little costly in the long run, and that’s a problem that the PARTU fixes. This one is excellent for getting rid of dust and mites, operates quietly, and would be a blessing if you own a pet.
If you’re looking for a thorough filtration process, the Coway AP-1512HH would be your best bet as it comes with a 4-stage filtration system. It also comes with indicators for the quality of air and changing filters. Not to mention, its 3-speed fan automatically adjusts the delivery power according to the quality of air.
Finally, if you’re looking for an extensive fan with four speeds, quiet operation, and blue light with three brightness settings for bedtime, you should opt for the TaoTronics TT-AP001.
