Top 10 Best Ventless Portable Air Conditioners – Ultimate List

Do you need an air conditioner that is movable?

And now you are thinking, “Even if I get one, will it be effective enough to cool my room?”

We understand it’s difficult to install a regular AC in all the rooms, especially if you are in a rented apartment. Moreover, it may become an expensive choice if it doesn’t work as desired to cool down your summers.

To help you better choose the best ventless portable air conditioner, we decided to perform extensive research. Based on it, we created this buyer’s guide for you. 

In this article, we have curated all our findings, including a list of the best 10 ventless portable air conditioners.

What Do You Need For The Perfect Portable Air Conditioner?

You must have a window or a hose for your Portable Air conditioner

The whole purpose of having an air conditioner is to cool your spaces. AC’s operate using a cooling agent called a refrigerant that absorbs heat from the air. At the same time, the AC unit uses a fan to redistribute the cool air in your rooms. In this entire cooling process, some heat is generated, which needs to be vented out.

If the hot air generated by AC is not expelled out, it will stay in your rooms, negating the entire cooling effect. And this is the reason you need a window or hose venting system to throw out the hot air so it’s not fed again in your AC unit and your rooms maintain cool temperatures.

Now, let’s look if there is an alternative to a hose or window?

You cannot avoid a hose or window prerequisite with a portable air conditioner. But, portable evaporative coolers, also known as swamp coolers, can be used to avoid a hose. These coolers use less energy but are powerful as air conditioners only in low humid places. Hessaire MC37M Portable Evaporative Cooler is one of the best-engineered coolers for indoor and outdoor spaces.

A Place to Drain Water from Humidity

Air conditioners use a condensation exhaust system to throw out water vapor collected during the dehumidifying/cooling process. This moisture is released through the connected hose along with hot exhaust air. So, for this reason, you need to drain water in someplace that is expelled due to humidity.

Most conventional air conditioners need you to drain water very often. However, modern air conditioners are designed with a water tank and dehumidifier that togetherly work as an excellent self-evaporation system.

Having an efficient self-evaporation mechanism reduces water drainage and reduces your efforts to expel the water accumulated in the hose regularly. Modern air conditioning propellers like EUHOMY 10,000 BTU Portable Air Conditioner also have sensors in the water tank that alert you with a sound if the water tank is filled and needs to be drained.

Each model has its own set of instructions for draining its water tank. Yet, the basic steps are somewhat the same for all as given below.

  1. Find a bucket or move the AC unit to a location to directly drain water into a sink.
  2. Locate the drainage plug on the back or side of the unit.
  3. Remove the drainage plug and rubber stopper to drain the water tank. Once the plug is removed, water starts draining freely.

Sizing The Room Appropriately For Your Space

Everything drills down to BTU’s (British Thermal Units) when choosing the right portable air conditioner for your rooms. BTUs are the unit rating based on which you can decide which AC unit will serve best for your room size.

It’s always a good idea to buy a 1000 BTU upper model in context to space when:

  1. Your room isn’t shady and faces south or west.
  2. You are looking for an AC unit in the kitchen which is both hot and humid.
  3. Your room is often crowded with more than 3 people.
  4. Your room height is greater than 8 feet.

Follow this chart to decide the BTUs you need to have in your portable air conditioners.

100 to 1505,000
150 to 2506,000
