Ventless Air Cooling

Ventless Air Cooling

People who live in hot climates can read this and find out about ventless portable air conditioners and other cool air solutions that both save money and bring welcome relief from the heat. There are more options than many people realize and these are worth exploring and highlighting.

While this blog focuses on the style of air cooling units that provide cool or cold air without needing to be vented to the outdoors, we'll also be covering other kinds of cool air solutions for hot climates. That means looking at air conditioning systems, portable units and alternatives that can both provide a cold air solution as well as bringing economical answers to the problems of rising power costs.

Did You Know..?

Top Rated Portable Vent Free Air Coolers

When you're looking for a great deal on the best portable air cooler models that don't require an exhaust vent that you can buy right now in 2016, finding this page was a stroke of good luck! That's because I know the secret to how to find the right cooling device that you really want and I'm going to reveal that secret below!

But first of all, I want to take stock of the most important aspects to you that I believe will define what is right in the perfect appliance to keep you feeling cool when it gets really hot outside.
  1. You want to feel comfortably cool where you are
  2. You want a healthy atmosphere to breathe
  3. You want to save energy and money
  4. You want a cooling device that does not need to be vented to the outside

We all know that a portable air conditioner will provide plenty of cold air, but a true AC needs to be vented to the outside and costs a lot of money to run because it uses a lot of energy. So a traditional portable AC is not really what you want, isn't that right?

That's why you came here in the first place: looking for a healthy, low cost alternative!

Let's take those points above and get some perspective.

Comfortably Cool

Being comfortable in all weathers is a natural human requirement that can easily be satisfied with modern appliances in the home or workplace. They include air coolers, heaters and ventilation systems that come in all kinds of configurations to suit individual wants and needs.

But you still want to enjoy all the benefits of AC with efficient air cooling but with economical power consumption and no exhaust pipe or hose to vent to the outside, right? Right!

For staying cool during summer, instead of expensive, unhealthy and cumbersome air conditioners, I focus on evaporative air coolers (swamp coolers).

These beautiful devices provide plenty of cold, moist air (which is better for healthy respiration) but only use a fraction of the energy consumed by power-hog ACs.

And they do not require an exhaust hose to vent anything to the outside. Perfect!

Healthy Breathing

A clean, healthy indoor atmosphere is what we all want to breathe, there's no arguing that one! A big downside to AC is that is dries the air, sucking all the moisture out of it. This can be tough on the delicate lining of our lungs and is especially tough on children, even though we think they're pretty resilient to these things when they're really not.

Evaporative coolers work in the opposite way to AC in this respect, by adding moisture to the air, not taking it away. This makes for a lung-friendly atmosphere and while we're about it, it's also very good for our skin and complexion.

Dry air has an adverse effect on our skin, aging and lining unnaturally if we're exposed to it for too long. Moist air is the opposite, hydrating and keeping it young and supple. I think I know which you'd prefer to have!


In this day and age, the way energy is being wasted while prices keep rising as natural resources are used up can upset a lot of people. It upsets me!

So I personally prefer to use appliances that are economical with their power consumption for all the right reasons. Swamp coolers typically use 1/20th the energy that comparable ACs use to provide the same level of cooling. That, for me is a sure winner and I'm pretty sure it will be for you too.

Portable Air Cooling with No Exhaust Vent

We all know that a portable air conditioner will provide plenty of cold air, but a true AC needs to have all the hot air it produces vented to the outside. So a traditional portable AC is not really what you want, isn't that right? That's why you came here in the first place!

Swamp coolers don't use compressors or refrigerating gases, so they don't produce any heat! None! They give you lots of chilled, moist air with no ugly exhaust pipe for a fraction of the running cost of air conditioning. And they're generally cheaper to buy!

So with the important stuff covered, I'm sure you want to see what I can recommend as, in my own opinion, the best swamp (evaporative) cooler on sale today for all the right reasons.

Best Free Standing Evaporative (Swamp) Cooler

In my experience, the top model non-AC air cooler is the Honeywell CL30XC. It has exceptional cooling power coupled with a big capacity and is super easy to use.

Best Cooler for Smaller Areas:

If you have a smaller room size that you need to keep cool and don't feel that you need the superior air moving capacity of the Honeywell above, take a look at this stylish yet compact portable air cooler from makers Luma Comfort.

This baby can reduce the temperature by up to 25 degrees in a room up to 250 sq ft.

It comes with a 1.75 gallon water tank making it smaller and lighter than other models. Yet despite its deceptively smaller size, it can provide you with several hours of great cooling before it needs to be refilled with water.

The Luma can be operated by remote control and it is easy to move around on easy glide wheels. It's great value for money, costs pennies to run and its attractively stylish looks make it stand out from the crowd.

What Could Go Wrong?

With all the incredibly positive aspects to this type of cooler, you are probably wondering if there is anything bad about them and why doesn't everyone stampede to the hardware stores and buy them all up? Well, there is a disadvantage that limits their use depending on where you live.

Humid climates and evaporative coolers do not go well together. The higher the humidity, the less effective these devices are at producing very cold air.

They are therefore NOT recommended for areas with high humidity, but work best in naturally dry climates. So if you live in a place that has a very humid climate, I would not recommend you buy a swamp cooler but instead you'll need to budget for the increased running costs of a regular AC unit if you want to have that comforting coolness when it gets too hot to do anything else.

In these cases if you want a portable cooler, you are limited to a vented AC unit. That means having to connect an exhaust hose to a window venting kit or other custom wall vent and paying a bigger utility bill... but at least you'll be cool!

A Fully Self Evaporating Portable Air Conditioner

One of the major annoyances of portable air conditioning units is the need to keep emptying the water tray. Fully self evaporating models avoid this problem altogether by ensuring all the moisture that is normally condensed from the air is evacuated through the exhaust vent to the outside.

How does this kind of device do this and how does it differ from regular portable units that need emptying regularly? Let's take a look!

Air Conditioning and Condensed Moisture

One of the aspects of the air conditioning process is when the warm air that is taken from the room is being cooled, the moisture present in that air is condensed on cold coils in the system. In as simplified as I can way of describing it, that condensed water is normally allowed to simply drip down into a catcher tray located at the base of the unit where it collects.

As the tray fills with water, it needs to be emptied manually or it will eventually overflow as a puddle on the floor. Emptying the tray is a task that has to be done or the overflow will need to be mopped up, making it a chore and a kind of a nuisance.

Fixed AC units don't generally have that problem, as the condensing happens outside the building in the external condenser unit, where the excess water simply drains away to the soil. Window units have a drain pipe that either drips to the ground below or some people allow it to empty into a bottle if the condenser unit is located on or above a balcony.

An Alternative Approach

Self evaporating portable air conditioner models tackle the problem of condensed water in a different way. Instead of allowing the condensing moisture to form a puddle in a tray, a secondary process operates to either re-evaporate that moisture or send it to a misting unit.

That makes it possible for the moisture to be mixed with the exhausted hot air and removed from the building through the exhaust vent hose though a window or other outlet. You can read more about venting a portable AC without a window here.

The additional processing inside the unit is minimal, with regards to the impact on the power consumption, making it a very useful feature. This is something that can be a big selling point for people that have already experienced the problem of having to empty a water tray in the past and are looking for a more convenient alternative.

What is the Best Portable Self-Evaporating Air Conditioner?

By taking my own experiences and those of friends and acquaintances, I have settled upon a model that I believe is one of the best portable self evaporating AC units in terms of cost, running cost, power output and ease of use. That unit is featured below.

Whynter ARC-143MX

This 14000 BTU Dual Hose Portable AC from Whynter includes a 3M antimicrobial filter that incorporates a patented advance auto-drain system. It works by recycling the moisture collected in the cooling process to actually enhance the production of cool air.

Add to that a dual hose operation that enables fast cooling and better economy, the ARC-143MX is perfect for general use in the home or office. It is especially suited to areas requiring low atmospheric moisture levels. These include computer server rooms, wiring closets or indeed anywhere that very low humidity levels are desired.

This great AC unit can be obtained from online stores as well as at physical hardware stores, although the online costs are generally lower (thanks to there being fewer overheads) and some vendors offering free shipping to mainland addresses. My store of choice is Amazon for their great customer service, free shipping on selected goods and general consumer preference.

There are other similar devices on sale at Amazon of course. Simply check out the alternative choices posted further down on the sales page of my feature unit (clicking the image above will take you directly to that page) if you would like to compare them.
