CoolJet AC is a personal misting/evaporative air cooler. Despite the "AC" in its name, it is NOT a compressor or refrigerant air conditioner, a window or portable AC unit, or a whole-room air conditioning replacement. It does not lower an entire room's temperature the way those appliances do. Its cooling is designed for personal, close-range comfort. Buyers should set expectations accordingly.
CoolJet AC's cooling is evaporative, so its effect depends on your air's humidity, the room size, and how close you sit. It performs best in dry conditions and at close range, and is weaker in humid climates. Any performance figures (temperatures, fan speeds, decibels, tank size, runtime, and coverage area) are manufacturer-stated and not independently verified here; real-world results vary.
Some third-party advertisements for products in this category make exaggerated or contradictory claims — for example, that a compact unit uses "Peltier thermoelectric" technology for a "rapid temperature drop," "cools any space in minutes," turns a room into a "chilled oasis in seconds," "covers up to 150 square feet," or is available only with a "limited stock / 50–70% off" countdown, alongside large "verified review" counts. Such claims do not originate from this independent review site, and we do not endorse or verify them. We aim to describe CoolJet AC honestly as a personal misting/evaporative cooler.
Independent reviewers have reported that the official CoolJet AC checkout has shown more than one price and more than one fan-speed specification, and that the money-back guarantee may deduct shipping from refunds. Before purchasing, read the order summary carefully and confirm the exact price, specification, guarantee window, and refund terms on the official store.
This general style of personal cooler is sold under many different brand names, and counterfeit products are known to appear on some third-party marketplaces. These may use inferior materials, may not perform as described, and may not qualify for the official guarantee. To protect yourself, buy only from the official CoolJet AC store.

No — and that's the most important thing to know. Despite the "AC" in the name, CoolJet AC is a personal misting/evaporative cooler, not a compressor air conditioner. It cools the air right around you and works best in dry air. It won't lower a whole room's temperature like a window or central AC. For personal, close-range cooling, CoolJet AC works well; for whole-room cooling, you need a real AC.
CoolJet AC uses a fan plus an ultrasonic nano-spray mist. Air is blown through the fine water mist, and as the mist evaporates it absorbs heat, so the breeze feels cooler and slightly humid. Adding ice or cold water to the CoolJet AC's tank makes the breeze feel cooler. It works best in dry air.
CoolJet AC is sold on the official CoolJet AC website (cooljett-ac.com), with lower per-unit pricing on bundles. Advertised discounts are against a high list price, so judge by the final checkout total — and confirm the exact price, since the checkout has reportedly shown more than one. Buy CoolJet AC from the official store for the genuine product and guarantee.
Less well — that's an honest limit. Because CoolJet AC cools by evaporation, it performs best in dry air. In very humid climates the cooling is weaker and it may mostly add moisture. Sitting close and using ice water helps the CoolJet AC feel cooler.
Generally yes on lower settings — the brand cites low-decibel operation (confirm). Many people run the CoolJet AC on their nightstand overnight. As with any fan, the higher CoolJet AC speeds are a bit louder than the lowest.
