1 sourceall derived$779.96as of Jul 31

The Della Vario Series 12000 BTU Mini Split Air Conditioner cools spaces up to 550 sq. ft. reliably. Users have praised how it works with smart home systems like Google Home and Alexa, and how easily it schedules for automated operation. A YouTube reviewer called it good value next to alternatives like Mr. Cool, which cost considerably more. On the downside, some users report the remote acting up intermittently, with the power button not always registering. Small to medium rooms where smart integration and energy efficiency matter are where it belongs, though anyone who wants a more dependable remote should consider alternatives.

Strengths
  • — Works well with smart home systems like Google Home and Alexa
  • — Effective for cooling spaces up to 550 sq. ft.
  • — Compatible with scheduling features for automated operation
Watch-outs

Mirage Ventus X
2 sourcesall derived$879as of Aug 1

The Mirage Ventus X is a ductless mini split built to cool and heat spaces up to 1,500 square feet. Reviewers pointed to its 19 SEER rating and quiet operation, with indoor unit noise between 35 and 51 dB. A 16 ft install kit with copper line set and a remote control come in the box. The value is good for the price, though the outdoor unit runs at 58 dB, which carries in a quiet setting. Medium-sized rooms and spaces where ductwork isn't practical suit it well; buyers who need more coverage or less noise should look at alternatives.

Strengths
  • — 24,000 BTU cooling capacity suitable for spaces up to 1,500 sq ft
  • — 19 SEER energy efficiency rating for cost-effective operation
  • — Quiet operation with indoor unit noise levels between 35-51 dB
Watch-outs
  • — Outdoor unit generates 58 dB of noise
  • — Limited to 1,500 sq ft cooling coverage

How they stack up

DELLA Vario Series 12000 BTU Mini Split Air Conditioner

The Della Vario Series offers smart home integration with Google Home and Alexa, a feature missing from the more basic Senville LETO Series. However, unlike the reliable Senville AURA Series with its premium compressor and Energy Star certification, the Della Vario has reported remote control issues and lacks the same level of build quality.

Mirage Ventus X

The Mirage Ventus X provides a 24,000 BTU capacity suitable for up to 1,500 sq ft, exceeding the 12,000 BTU capacity of the Della Vario Series. However, unlike the Della Vario's smart home integration, the Ventus X lacks WiFi connectivity and is louder outdoors at 58 dB compared to the Della's quieter operation.
