KOIOS is a budget brand best known for horizontal slow (masticating) juicers sold mainly on Amazon. Its popular models promise cold-press style juice, a reverse function to clear jams and a quiet motor at a fraction of the price of Omega or Kuvings. Here is what KOIOS juicers do well, their limits, how the main models differ and who should buy one.
Verdict: A KOIOS masticating juicer is a solid entry-level slow juicer if you want better green juice than a centrifugal machine on a tight budget. Expect more prep (small chute), a slower process and a shorter track record than premium brands. If you juice daily, an Omega or Kuvings slow juicer usually lasts longer and comes with a much longer warranty.
KOIOS Juicer
pros
CONS
What Kind of Juicer Is KOIOS?
The best-selling KOIOS models are horizontal masticating juicers: a single auger turns slowly to crush produce against a screen, rather than shredding it at high speed. Retail listings typically describe a low speed of around 80 RPM, a reverse function and a quiet motor; check the current listing for your exact model, because specs change between versions.

The difference between the KOIOS Juicer and the KOIOS Upgraded Juicer Machines lies in the specific features and improvements introduced in the upgraded model. The upgraded version may include enhancements such as improved motor power, better juice extraction efficiency, or additional accessories for a more versatile juicing experience. When choosing between the two, it’s essential to consider the specific upgrades offered by the newer model and determine if those improvements align with your juicing preferences and needs.
When comparing these two best masticating juicers, the KOIOS Juicer to the KOIOS Centrifugal Juicer Machines, the key difference lies in the juicing mechanism. The KOIOS Juicer typically employs a masticating or slow juicing method, which is known for preserving more nutrients and minimizing heat build-up during the process. On the other hand, KOIOS Centrifugal Juicer Machines use high-speed spinning blades to extract juice quickly. The choice depends on whether you prioritize nutrient retention and a slower juicing process or seek the speed and convenience offered by centrifugal juicers.
When comparing the KOIOS Juicer to the KOIOS Slow Juicer Extractor, the key distinction lies in the juicing speed and extraction method. The KOIOS Juicer operates at a faster speed, making it suitable for a quick juicing process, while the KOIOS Slow Juicer Extractor utilizes a slower speed to extract juice, focusing on preserving maximum nutrients and minimizing oxidation. The choice depends on whether you prioritize speed or nutrient retention in your juicing experience
