Best Ventless Portable Air Conditioner (No Window And Venting Needed)

Best Ventless Portable Air Conditioner

The term ventless has come into fashion as a term being thrown around with relation to Air Conditioners lately. The word itself seems to imply an Air Conditioner that doesn’t need an exhaust vent, and so, needs no fixing.

While, of course, this sounds like the pinnacle of comfort and convenience (I mean, you’re escaping that frustrating tunnel of AC installations and fittings and sizings), there’s one thing I want to clarify: Air Conditioners cannot be ventless.

I’m not trying to let you down on purpose here. If you’re looking for someone to blame, consider the natural laws of science.

The principle of any AC functioning is that hot air from inside the room is gathered and exhausted outside. That is the only way any Air Conditioning unit would work, so I advise you not to fall for the ventless AC mumbo-jumbo. However, this is not to say that there are no other cooling devices that can service you without requiring a window or a vent. 

So Presenting to you: Evaporative Coolers. They can work greatly in your favor if you’re in need of a cooling unit but don’t have access to a window. You’ve got to battle those summer degrees with any means necessary.

For this reason, I’ve compiled a list of some Ventless Portable Air Conditioners that don’t need a window (which you know is code for evaporative coolers or just the usual portable air conditioners) for your enjoyment.

Best Ventless Portable Air Conditioner In The Market

  • Zero Breeze Mark 2 Ventless AC
  • Homelabs Portable Ventless AC/Evaporative Cooler
  • Hessaire MC37M Portable Ventless AC/Evaporative Cooler
  • Hessaire MC61V Portable Ventless AC/Evaporative Cooler
  • Honeywell Portable Ventless AC/Evaporative Cooler

1. Zero Breeze Mark 2

Okay, I might have lied when I said there are no ‘ventless’ portable AC units. There are always exceptions to the rule, right? The exception, in this case, is the Zero Breeze Mark 2 Air Conditioner.

You can think of this air conditioner as one that closely resembles a ventless cooler, but is actually an AC unit. It’s confusing, but the fact is that this is not a cooler trying to be an AC, but rather the other way around.

Its whole appeal is facilitated by its unique design and structure. The AC simply has a very light hot air outflow compared to normal ACs. So while the unit still exhausts hot air, it does so at a low rate of 152 CFM, which is also a good thing because it means noiseless operation.

As it doesn’t release heavy amounts of hot air like other ACs, it doesn’t cause a lot of ruckus at only 52 dB. So, since the unit is still an AC, it requires to operate at a cooling capacity of 2,300 BTU. So, if you absolutely want only an Air Conditioner without venting requirements, the Zero Breeze Mark 2 is our go-to.

Pros
  • It has a great airflow rate.
  • As it is an actual AC, you can expect it to have a real cooling effect by eliminating hot air.
  • It has a durable and sturdy build quality.
Cons
  • It is quite expensive, priced at around $1000.
  • As it still uses venting technology, you will have to put up with some level of noise, though not a lot.

2. Homelabs Portable Evaporative Cooler

This Portable Evaporative Cooler is something to consider if you’re looking for a cooling unit to make the summers more bearable. Portable Coolers and ACs are great because they don’t require any long-term commitment, meaning that you can happily put away your cooler once summer break is over.

Moreover, a cooler itself doesn’t pose too many problems with set-up, as it needs no window. For this reason, this Portable Evaporative Cooler by Homelabs is a smart choice.

With very small dimensions measuring only 7 x 13.1 x 34 inches, it won’t take up too much space. You can load its water tank up to 10 Litres, and it will easily cool an area of about 200 sq ft in no time.

You not only get a small and efficient system but also have features like a digital control panel by which you can set the speed, temperature, swing direction, etc, according to your liking.

There is also a 24-hour timer, so you don’t have to wake up in the middle of the night to turn the cooler off. In terms of build, it comes with a removable nylon air filter that traps dust and debris.

Pros
  • It is simple and affordable.
  • It has a smart LED panel through which you can control all its functions.
  • It is a small and compact unit which saves you a lot of space.
  • It is great for places with moderate weather.
  • It has an ice tank that boosts its cooling capacity.
Cons
  • It doesn’t have a large airflow rate compared to other models on this list.

3. Hessaire MC37M Portable Evaporative Cooler

This model from Hessaire- the MC27M is considered to be one of the best-selling coolers of its time and is one of the top units from Hessaire’s collection of coolers. Other ventless coolers have a long way to go to catch up with the MC37M.

This is mainly because of this cooler’s winning feature: its excellent airflow. Where most coolers operate at a CFM of 200-400, the MC37M exceeds expectations really. The model has a CFM of 3,100.

Basically, if you bring this device home, you may have icicles dripping down your ceiling. Kidding- but really! If you live in an area where hot summers are no joke, this cooler can be a godsend. 

Through the 3,100 CFM, it can cover an area of 950 sq ft. Another great feature of this cooler is that despite the heavy airflow, it is relatively silent and makes only 59 dB of noise. The engineering is really convenient compared to even most AC units.

Pros
  • It has a great airflow rate at 3100 CFM, so it can cool you down in the hottest weather.
  • It works noiselessly.
  • It is from a long trusted and reliable brand.
Cons
  • It can take up quite a bit of energy, so it’s not exactly power-saving.
  • The airflow can be overbearing. However, it is adjustable.

4. Hessaire MC61V Portable Evaporative Cooler

The MC61V is another remarkable cooler from Hessaire, which makes the MC37M look inadequate. It is especially perfect if you’re looking for a cooler as you travel, trek and camp during summer.

Its ventless cooling system means that you don’t have to spend any time and energy worrying about installation, it fits right into nature’s window! Its lightweight and sturdy design at only 84 pounds make it a perfect build for outdoor use.

Additionally, this model has an unbelievable CFM of 5,300 units and can cover up to 1,600 feet, so it has an extremely powerful cooling power that can efficiently cool up quite a big area- perfect for a patio party or an evening chilling in your backyard.

The MC61V definitely does not fall short on features and technology. It can be filled with up to 14.6 gallons of water, so you can rest easy for 4 long hours. It has simple controls to adjust the speed, swing, and pump. You can also keep the cooler continuously recharged with water by attaching it to a hose or pipe.

Pros
  • It is the perfect cooler for the outdoors.
  • It is durable and strong.
  • It has a big water tank that can go on cooling for 4 hours.
  • You don’t have to manually load it if you connect it to a hose.
Cons
  • It does not work great in places with high humidity.
  • You have to be careful with the automatic fill feature as it might overflow without proper supervision.

5. Honeywell Portable Evaporative Cooler

After having read through the reviews of the top dogs in the industry, this cooler might seem a little underwhelming to you. The Honeywell TC10PEU is a simple model that adheres to the usual standards of air coolers.

In my opinion, if you’re looking for a cooler to just do its job without much fanfare, this might be it. It doesn’t have a display of extravagant features. What it does have, is a comfortable level of efficiency that’s just enough for your home. 

Of course, vents and windows are no problems to this unit, it uses evaporating technology to get rid of humidity, and doesn’t need to be fixed. The cooler has a 194 CFM airflow rate, which fills the room with gentle cooling.

Perhaps one of the best things about the TC10PEU is how affordable it is. At only $200, this cooler gives you all the basic features in any cooler while being generous to your wallet.

Pros
  • It is extremely affordable.
  • It has simple functioning. It is enough for basic cooling.
Cons
  • It doesn’t have a great airflow rate.
  • It doesn’t have the excellent technologies and features like other models on this list.

Ventless Portable Air Conditioners: Buying Guide

There are many reasons you should go for a Ventless cooler instead of an air conditioner, but there are also reasons not to. The first thing you’ll want to check for before investing in an evaporating cooler is the climate. 

Coolers are quite useless under extremely hot and harsh weather but can work for semi-arid climates. However, they are certainly more cost-effective than AC’s- especially if you’re not looking to make a long-term investment. Also, you won’t have to be involved in some long and complicated setup procedure where you have to make sure your window and AC are compatible- as most of them are ventless. 

They are also great in terms of energy-conserving. However, you’ll have to compromise in aspects like cooling power. Despite all that, if you know that you definitely want a Ventless AC like unit, here are a few pointers to help you find what you want from your purchase:

Airflow and Cooling power

The most significant aspect to take note of while you browse through different models is the airflow or the CFM rate. The most basic thing every customer requires from an AC or any cooling unit is for it to effectively cool an area as much as possible. So, a high cooling rate is ideal, although you might be willing to compromise it if you come from warm climates and if the cooler promises much better features.

Ice Tank

Again, what makes a good cooler is that it cools to the maximum capacity. That is why coolers with ice tanks are preferable to those with just water tanks. Ice is way colder than water, so the resulting breeze from your cooler would also be much lower in temperature. An Ice tank can really boost the cooling capacity of the cooler.

Noise Levels

No one likes the empty vessel that makes the loudest noises. It can be disrupting and irritating. Noise is something to be wary of when an AC unit comes with a high airflow rate because this means it would exhaust more hot air per second. However, coolers don’t have vents, so it is a little alarming if a cooler is annoyingly noisy although it doesn’t expel any hot air at all.
