If you want to research all the specifications for any model, we do not recommend the Della website. For some reason, it lacks detail.
You’ll find more information by clicking the Amazon links below in our Top Picks section. There is significantly more detail there.
1. Dehumidify Mode
Most portable air conditioners have this mode. It dries the air without cooling it. That is, moisture is condensed out of the air and evaporated out the exhaust hose on most models. The 8K model has a tank that will periodically need emptying.
The heat removed by the refrigerant is cycled back into the air, not exhausted. If you’ve ever run a dehumidifier, you know that the back of them gets warm from the heated air.
Benefit: Depending on your climate, there might be seasons of the year when drier air would be nice, but you don’t want it cooled.
2. Evaporative Technology
When cooling or dehumidifying the air, moisture is removed. The moisture condenses on the cooling coil. Instead of draining into a tank or through a hose to a drain, the moisture is evaporated and exhausted out the hose attached to the window kit.
All Della portable ACs except the smallest model, the 8K BTU 048-GM-48266, use evaporative technology.
Benefit: There are no drain reservoirs on these models, so you don’t have the hassle of having to empty it or have the unit shut down because the tank is full.
3. Heat Pump Heat
The 14,000 BTU Della 048-GM-48384and Della 048-GM-48335 are true heat pumps. A reversing valve causes the refrigerant to flow in the opposite direction to pull heat from outside air, with the exhaust hose as a conduit.
Here’s a brief overview video of the 48335.
Benefit: If you have a room that need a little heat, getting it from a heat pump is more cost-effective than space heater heat. I.e., it costs to run a compressor that cycles heat-absorbing refrigerant than it is to create heat with an electric resistance element or coil.
4. Convenience Features
All models come with remotes you can use to control all the AC’s functions.
They also have 24-hour timers, which offer more than just convenience. These timers also help you save money and enjoy comfortable space.
For example, in hot weather, you can leave the unit all while you’re away, so it is cool when you return. But that’s a waste of energy and money.
Instead, set the timer to turn the unit on 30-60 minutes before you expect to be home, and it will be cool and comfortable when you arrive.
Benefits: Convenience and energy reduction.
Features Not Available on Della Portable ACs
There are a couple things Della doesn’t offer.
1. Dual-hose Models
These are single-hose portable air conditioners. When they run, air is pulled into the unit from inside the room, and heat and humidity are removed and exhausted.
This creates negative air pressure in the room, so air from outside the room, even outside the house, is pulled inside. That air is warmer and more humid, so it harms the net efficiency of the AC.
A two-hose portable air conditioner is 7% to 12% more efficient, depending on the model. That’s not great, but it helps. Air is pulled into the unit. Heat and moisture are removed, and the air is returned to the room, not exhausted.
The first hose draws in outside air to cool off the very hot compressor and refrigerant. The second hose exhausts the heated air. There is no interaction of inside and outside air.
2. WiFi or Smart Units
DeLonghi, Hisense, Frigidaire and LG have WiFi-equipped models. Most also work with one of the smart voice-controlled speakers, Alexa or Google Assistant.
Della hasn’t released one yet, but we suspect they will. The company is young and forward-thinking, so it is probably just a matter of time.
How Della Portable ACs Compare to Other Brands
There are similarities and differences, pros and cons.
Overall, while the brand currently has few models, they are good performers, and the quality is better than average.
One thing to note about models is that many are listed as Out of Stock on the Della site. That frequently means they are discontinued. We didn’t include those models in the review.
Pros: Most models are evaporative, have dehumidifier mode and are equipped with a timer and full-function remote.
That puts them on par with the portable AC lineup from LG, Haier, DeLonghi, Honeywell and other “big” names.
Cost is lower. These are competitively priced portable air conditioners.
Cons: There are no dual hose models and no WiFi models.

Choosing the Right Della Portable AC
There is a wealth of buying information in our complete Portable Air Conditioner Buying Guide, but here are the key points.
1. Measure the space to be served, length times width, to know how many square feet are included.
2. Add 10% to room space if the ceilings are 9 feet high; add 20% if the ceilings are 10 feet high.
3. Consider a heat pump model if you need space heating and times during the year.
And if you want a feature not available on Della models, see our reviews of other major brands. You’ll find the full range of options among those brands. Each has quick links to models with the features you want.
