1. Black Decker BPACT12WT

The Black Decker BPACT12WT cools, dehumidifies, and improves air circulation. In addition, this Black Decker model won't interrupt your sleep by offering immediate, uninterrupted comfort.

The installation kit includes:

-   Air exhaust hose

-   Hose inlet/outlet adapters

-   Window casement

-   Water drain hose

-   Owner's manual all included

  • Cooling Power — 80%. 6000 BTUs is enough to cool down a 300ft2 room with regular ceilings.
  • Portability — 90%. This model will do a great job as long as you place it in a room with a window. However, it can be too voluminous for small spaces, so make sure you size the device correctly.
  • Setup — 50%. You need to place the exhaust pipe in the window, which can be a disadvantage for the room's decoration. A few reviewers complain about the setup:

"The vent hose does not sit securely on the rear. Any tension with the hose, combined with the heat, causes the vent hose ring to warp and tilt away from the unit, creating a separation gap where the exhaust leaks out. The unit itself can't cool properly because of this fault".

  • Noise — 100%. For the 6000BTUs, this is one of the silent portable air conditioning units on the market.
  • Price — can vary based on the retailer.

Why you should get this Black Decker portable air conditioner model:

  • Low noise levels. This device has made it to the list of most quiet portable air conditioners in 2021 a few times. 51Db is the equivalent of a quiet conversation.
  • Relatively reasonable price. Many models with the same configuration and BTUs cost more.

Why you may want to hold off the purchase:

  • Design. If you are a visual person who is very sensitive about the décor, this particular model can be an eyesore.
  • Size. Given the dimensions, this is not an ideal device for the temporary cooling of small rooms.
  • Setup difficulties. Several reviewers complain about the challenges of adequately setting the hose in the window and electronic outlet requirements.

You can get it at Lowe's, starting at 357$.

2. De'Longhi 12500 BTU

  • Cooling Power — 100%. 12500 BTUs is a good power for a medium-sized or a larger room.
  • Portability — 70%. With 71 pounds weight and 30 inches height, this is not exactly as light as a portable air cooler. However, as long as the room has a window, you can place it anywhere. Caster wheels and integrated handles allow you to move it quickly from room to room.
  • Setup — 50%. While the physical setup is easy, many users complain about having to install many different applications that don't work.
Qries

Detailed review about the setup:

To get this machine working with Alexa, you need a total of 3 different apps!

First, you have to get the Delonghi Pinguino App and update the system firmware. Second, you have to install the Smart Life App and the third app in the Alexa app. After you set the machine to work with Smart Life, the Pinguino app loses the machine. But you can still start the Pinguino app from the smart life app and control your machine from there (Confusing, I know!). If you use the Smart Life app to show details of the machine, it will display a firmware error. But don't worry, it will still work. Alexa finds the machine by installing a Smart Life skill. Alexa identifies the machine as a thermostat, and you can turn the machine on or off, set temperature targets, etc., with Alexa. Your Wi-Fi has to support 2.5ghz for any of this to work.

  • Noise — 100%. For the 12500BTUs, this is one of the silent portable air conditioning units on the market.

Review on the noise:

"Noise level same as other products in the market"

  • The cooling power and the noise level ratio make it one of the best quiet portable air conditioners
  • If you enjoy new hi-tech add-ons to known products

Why you may want to hold off the purchase:

  • This is not exactly a model for non-tech-friendly people or simply those who don't think that several applications are necessary to work with only one device
  • This model is more expensive than models with the same criteria in other brands.

You can get it on Amazon starting at 605$

What to Look for When Buying a Quiet Portable AC

1. Performance

Check out the BTUs and make sure you are sizing the unit right. The cooling power of a specific AC model can be proportional to the noise, even though it's no longer the case for modern air conditioners.

2. Decibels

The Dbs will give you the best idea of how quiet the portable air conditioner is. Rule of thumb: go for models under 60 Db, with 55 being the equivalent of a conversation. Also, check out if an air conditioner has a quiet (sleep) mode, where the fan turns less and produces less noise.

3. Positioning of the device

Even the quietest air conditioner can become a nuisance if it's too close to you. So before you go with any type of model, make sure that it isn't in immediate proximity no matter what. The positioning will also depend on the size of the device.

4. Personal preferences

Is the noise more of a distraction when you are sleeping or trying to focus? Are you willing to sacrifice a bit of comfort as long as it is quiet? Did you make a choice because you know for sure air conditioners are good for you? It is up to you to decide!

If you don't own an HVAC, can't be bothered to install a window air conditioner, or if you don't feel like investing a few hundred into an air conditioner, we have the perfect solution for you!

7.     Evaporative air cooler by Evapolar

The cooling method differs between a portable air conditioner and an evaporative cooler. Air coolers use evaporation, making it a healthy and silent process. If we consider all the points we've clarified with portable ACs, let us see how this powerful evaporative device compares to the bigger cooling brothers.

  • Cooling power would be wrong to compare. Both ACs and air coolers use BTUs to measure the power. However, they serve a different cooling goal. Evaporative air coolers cool down your immediate surroundings within moments, while air conditioners focus on the whole room. So, if you are looking to cool down the entire area, you might go with an AC. However, if you need a personal cooling method, the air coolers will be more powerful.
  • Portability — 100%. You can place your Evapolar device anywhere and even take it on a trip. They are super lightweight and portable.
  • Noise – 100%. Somebody very into detail has reviewed the evaCHILL air cooler by Evapolar on Buzzfeed and measured the decibels directly. At the highest speed, the device produces less than 60Db, and it also doesn't generate a buzzing noise that most electrical appliances make.
  • Setup – 100%. There is nothing to say here since you only need to plug the device and direct the airflow at you with the help of the air grill. What makes it the best desktop air conditioner of choice
  • Price. Evaporative air coolers fall into a cheaper category (the Evapolar bestseller costs 119$), and they also require way less electricity than portable air conditioners. So stay cool and save in the long run.

As you can see, the only difference where the air coolers are less potent than portable air conditioners is the covered area of cooling since they use different cooling methods. However, they are quieter, cheaper, and way more portable than the rest. So if you are looking for the quietest portable air conditioner and want to cool down your personal space only, an evaporative air cooler is the best investment you can think of.

People also ask (FAQ):

1. Are portable air conditioners quiet?

Modern devices are quieter than previous generations. However, we recommend you always check out the decibels on the box. If the noise is a significant criterion for you, don't hesitate for the vendor to show you directly how it works to measure the decibels yourself if you are shopping in person.

2. What is the quietest portable air conditioner today?

There are models in the range of 45-55 decibels, which is as quiet as it gets. Of course, a device will still generate some noise. However, 45-55 decibels are next to regular white noise.

3. Does the air conditioner performance influence the noise?

Sometimes more powerful cooling systems generate more noise than the less powerful ones. However, the difference is less significant in modern devices.

4. Is an evaporative air cooler quieter than a portable air conditioner?

Some air conditioners are as quiet as portable air coolers. However, an evaporative air cooler is usually quieter than most AC models.

5. Is a quiet AC more expensive than a regular one?

Not necessarily because many criteria come into the price. However, designing a sleek and silent model is usually a more considerable investment than the known formula. If you are hesitant about the price, a portable air cooler costs at least three times less than an AC and is very quiet at the same time.
