What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

Different Types of Portable Air Conditioners

Monoblock Air Conditioners

Under monoblock air conditioners, the portable AC model may have a single or dual hose model. Single-hose models have only one hose that connects outside where the machine extracts the warm air to. The hose is present only to remove the warm air from the room, and the unit uses the air from inside the room for airflow.

Single-hose portable air conditioners tend to use up more energy than the dual-hose system, and are best to use as an additional cooling unit instead of the main air conditioning system. Still, the single-hose type is portable, easy to set up, and readily available across multiple brands and variations.

The dual-hose portable air conditioner, on the other hand, uses two hoses directed outside: one is used to remove the warm air from the room, while the other is used to bring in air from the outside. This model uses less pressure, which tends to use up less energy continuously running the air conditioning system.

Split-type Air Conditioners

Split-type portable air conditioners, much like their wall-mounted counterparts, have two separate units that connect through a flexible hose. The indoor unit works like any portable air conditioner with the addition of an outdoor unit for condensing and compression.

The split-type model is less portable than the monoblock model, but it is the quietest portable air conditioner type in our list. It is also generally the most expensive, as advanced models may go upwards of $1000 per unit, especially for a smart portable air conditioner with a programmable timer and advanced features.

Air Coolers

An air cooler is a type of portable air conditioning unit, but it has a lower cooling power than that of a monoblock or split-type portable air conditioner. They do, however, remove excess moisture along with the hot air extracted from the room, so you won't need to worry about the condensation.

However, these units are not often popular with large areas as they inefficiently cool rooms larger than 15 sqm. They are affordable options, albeit they do not provide the same cooling factor you may be looking for from other portable air conditioners.

How They Work

How Do Portable Air Conditioners Work (Complete Guide)

Portable air conditioners work no differently than other types of air conditioners in keeping a room cool. A portable air conditioner would typically have a hose that extends to the outside of the room, either via a small opening in the window or through a vent, that extracts the warm air from the room and sends it outside.

As the machine picks up the stagnant air around the room, the compressor runs the air through cool coils, lowering the temperature, and bringing the now-cold air back into the room. On the other hand, the compressor also collects the warm air and pushes it out of the room through the hose. This heat extraction process is what cools a room.

Portable air conditioner compressors operate both hot and cold coils simultaneously, effectively cooling down the room. The cooling power of the portable AC unit depends on its British Thermal Units (BTU). The higher the BTU, the larger the room area one unit can effectively cool.

Factors to Consider When Buying


Much like any large home appliance, portable air conditioners can cost you a pretty penny. Most standard units can cost you between $300 to $400, with portable AC units made for large rooms costing upwards of $800. Consider your budget first when buying so you don't overspend for your portable air conditioner.

Energy Consumption

Besides your initial spending budget, consider the costs of running the unit. A portable air conditioner has an average energy consumption of 2900 watts per hour for mid-sized units. You will need to be prepared for the electricity costs of running a portable air conditioner, and decide if you can go for a unit with more energy efficiency.

Space Requirements

Portable units are often smaller and more lightweight than your average window-type or wall-mounted air conditioner. You probably won't have too much trouble fitting the machine into your room. However, the vent must not be covered or limited, and you will need to find a space where the hose can be directed outdoors.

Consider if you have the space for the machine before you purchase, especially if you're looking at split-type portable air conditioner models that will require you to install an outdoor unit, limiting the portability of your AC.

Cooling Power

A portable AC is much more affordable and easy-to-install than a wall-mounted air conditioner. They are smaller than most AC types, and However, portable units generally have a lower cooling capacity than other types of air conditioners, so pay attention to the area capacity your unit can effectively cool down.

Most portable air conditioners have a seasonally adjusted cooling capacity, which will adapt the temperature of its cooling coils to the temperature outside. Still, you may need a unit with higher BTU than recommended for exceptionally hot weather and climate.


Most air conditioner maintenance companies are well-versed and experienced in servicing wall-mounted, window, and ceiling or central air conditioners. However, not all companies may be experienced with your particular portable model. Portable units do not require much maintenance, but they can be difficult to clean and service when you do need to take it to the shop.

Before deciding to buy a portable unit, check to see if you have a local maintenance company near you that can service your particular portable model.
