Finding the right portable air conditioner for your home isn’t always as easy as you might imagine.

After all, there’s a lot to take into account. Not only do you need to consider the capacity of the unit, but you also need to think about its cost, its noise level and its aesthetic.

There are also plenty of different units on the market to choose from, so how do you know which one is right for you? 

The Honeywell MO08CESWK compact portable air conditioner is one popular choice. Made by a reliable manufacturer, it’s easy to see why many people choose Honeywell portable air conditioners for their home.

The only way to make an informed decision is to read Honeywell portable AC reviews so you can get all the information you need.

With this in mind, here is a Honeywell air cooler review that will tell you all you need to know about the popular Honeywell MO08CESWK model.

A Reliable Model From A Reliable Manufacturer

When you need powerful airflow but want a compact air conditioner, the Honeywell portable evaporative air cooler could be the ideal choice for your home.

The Honeywell brand is well known for its high quality and this model won’t disappoint thanks to its premium components and outstanding customer service from the manufacturer.

Your purchase comes with a peace of mind manufacturer warranty so you can be completely confident that, in the unlikely event of a fault or issue developing, you’ll be well covered for any repairs or replacement parts. 

Ideal For Large Spaces

The Honeywell portable air conditioner is a perfect choice for larger spaces. Capable of cooling spaces of 350 to 450 square feet, this is an ideal model for a living area, bedroom or any other part of your home where quiet operation and effective cooling are required. 

Saving You Money And Energy

When you choose a portable air conditioner like this model from Honeywell, you can not only do your bit for the environment, but you can also save yourself money too on your energy bills.

Since you’ll only be cooling the room you’re using at the time, you’ll be able to slash the cost of operating a full-home air conditioning system. Also, since the fan speeds can be adjusted with ease, you can achieve the cooling that you desire and reduce your energy consumption at the same time. 

More of us than ever before are concerned about our carbon footprints and about reducing our energy consumption in the home.

This portable and compact air conditioning unit is a great choice to help promote those goals, allowing you to minimize the amount of energy you use at home to keep yourself cool and comfortable at all times. 

3 in 1 Functionality

One of the best features of the Honeywell portable AC unit is its three-in-one functionality.

Not only does this unit efficiently cool your home, it also offers auto-evaporation with an inbuilt dehumidifier that is capable of removing as much as 44 pints of water vapor from the air in 24 hours.

It even features a continuous draining option so you can leave it operating unattended for even longer.

This makes the Honeywell unit an extremely convenient and user-friendly appliance for anyone who wants a low maintenance device. 

The third mode of operation is the fan. We'll discuss this in just a moment.

Improved Breathability In Your Home

The Honeywell air conditioner comes with a washable filter so you can improve the air quality in your home.

Thanks to a Washable Dual Filtration System, pet dander, hair and dust can easily be filtered out of the air to protect and extend the life of the air conditioner, giving you even better and longer-lasting value for money while reducing the impurities and contaminants in the environment.

You and your family will be able to breathe more easily, and since there is a filter change alert indicator built into the unit, you’ll be able to see at a glance if it’s time to wash the filter which can simply be rinsed out under running water, with no need to buy a replacement filter, saving you money on consumables in the long run. 

Great For All Sizes Of Window

This portable air conditioner can be fitted to windows with a bracket width from as little as 19.7 inches right up to 47.2 inches, so you’re sure to be able to fit it in your home with ease.

Thanks to the quick and speedy installation, you’ll be cool and comfortable in no time. Suitable for installation on horizontal or vertical windows, it comes with everything you need to fit the unit quickly and easily.

Even better, if you need to move your air conditioner between different rooms and spaces of your home, this compact model is ideal for you.

It comes complete with smooth-gliding wheels, and as it is one of the lightest models in its class, it weight only 45-49lbs, making moving it between rooms a breeze.

Whisper Quiet Running

Thanks to the dual motor technology that is integrated into the Honeywell air conditioning unit, you can enjoy a much lower noise level when this unit is running in your home.

Even when at its highest speed setting, this portable model only produces between 50 and 53 decibels which is only around the same level as an average conversation taking place in a quiet space!

Therefore, you can easily use this air conditioner in your bedroom or home office without having to worry about being disturbed by excess noise. 

A Multi-Speed Fan

Part of the three-in-one functionality that this model offers is its multi-speed fan which can be adjusted using the digital control panel or the remote control to the speed that best suits your needs and your preferences.

It’s never been easier to get the perfect temperature level for your home, so whether you need a little boost to your home’s air circulation or a powerful cooling breeze, this unit can accommodate your requirements. 

Set And Forget

Another excellent feature of this air conditioner from Honeywell is its ability to be set and forgotten about. You can benefit from precise and simple climate control in the room of your choice thanks to the Smart Digital Thermostat system which is integrated into this model.

You’ll benefit not only from clear digital controls but also a fully functioning remote control that allows you to change the settings with ease from any spot in the room.

Easy Maintenance, Easy Storage

The Honeywell AC unit has a self-evaporation system which means that it has a bucketless operation.

When you’re using this unit in a higher humidity room, the unit features dual drainage options to offer you more flexibility and if you’re using this model as a dehumidifier, you can even set up a continuous drainage system which ca be set up in just a few minutes for extra convenience. 

When it comes to storage, this AC unit also ticks all the boxes. Thanks to its wheels, you can simply roll it into a storage space or another room without any difficulty. 

A Compact Size

Just because you need to cool a large space doesn’t necessarily mean you have a lot of room to store or accommodate a large and bulky air conditioner.

This Honeywell model is designed to be very compact, so you can easily fit it into even a smaller space or corner of your home. It also features an attractive and modern streamlined design, so it will look unobtrusive and discreet in any room.

Designed to the highest standards and manufactured using the best components, it will stand the test of time and give you many years of excellent cooling.

It is also capable of cooling rooms that measure up to 350 square feet, so you’ll find that it functions effectively in virtually every space of your home. 

Add into the equation the fact that it runs extremely quietly, even on its highest setting, and you’ve got a compact and easy to use air conditioner that works perfectly even in bedrooms or other noise-sensitive spaces.

Its gliding wheels allow you to move it with ease around your home to provide optimal cooling whenever and wherever it’s needed, and its remote control option means you don’t even need to leave the sofa to adjust the settings to suit your individual preferences!
