Method One: Spray equipment has very strict requirements for water quality, and the water treatment system is a critical detail that should not be overlooked. Natural water sources contain impurities to varying degrees, and may even harbor harmful substances. If these are not properly treated, they can not only impair the equipment’s normal operation but also pose health risks to humans. Therefore, the availability of a high‑quality, dedicated water‑treatment system should be an important criterion when selecting spray equipment.

Method Two: Consumers should understand that the key component of misting equipment is the nozzle. Abroad, nozzles are categorized into landscape‑grade and industrial‑grade types, which differ in their fog‑producing performance and vary significantly in price. Users should select based on their specific needs. The primary criterion for distinguishing between landscape‑grade and industrial‑grade nozzles is the size of the nozzle’s spray orifice.

Here’s a simple method for determining nozzle size: measure the water flow rate of each nozzle per hour. Typically, landscape‑grade nozzles consume about 5–6 liters of water per hour, while industrial‑grade nozzles use roughly 10–12 liters per hour.

Nozzles made from different materials exhibit varying levels of pressure resistance and wear resistance. Common materials include polypropylene (PP), copper alloys, stainless steel, and ceramics. Stainless steel offers superior pressure resistance, and landscape‑grade nozzles are often constructed from this material. Additionally, high‑quality nozzles are equipped with secondary atomization pins.
