Chlorination disinfection is one of the most common and effective sterilization methods. Chlorine can effectively kill Legionella in whirlpool spa hot tub water, provided that the chlorine concentration is sufficient and the contact time is long enough.

Whirlpool spa hot tubs, with their warm and humid environment, provide ideal conditions for the growth of Legionella bacteria. If a whirlpool tub's water treatment system or disinfection measures are inadequate, Legionella bacteria can rapidly multiply and spread in this environment.

Whirlpool hot tub water often uses an alkaline or acidic adjuster to maintain the pH within the appropriate range to prevent corrosion and minimize equipment damage. Excessively high or low pH levels can significantly affect plants and lawn soil, disrupting the soil's acid-base balance.

Risks of using high-pressure water to rinse spa hot tub filters without removing them: 1. Damage to the filter structure 2. Incomplete cleaning 3. Damage to the filter's mounting and mounting mechanism 4. Potential water pressure issues

The pump, pipes, and seals in a spa hot tub may dry out after prolonged periods without water, accelerating aging. Some materials require a certain level of moisture to maintain elasticity and sealability. If these components are exposed to air for extended periods, they may crack or lose their function, shortening the lifespan of the spa hot tub.

Legionella is most active in warm water environments (typically between 20°C and 50°C), with optimal growth in the 35°C to 45°C range. Legionella growth is inhibited or stopped below 20°C or above 50°C. Therefore, whirlpool hot tubs, water towers, and other facilities with warm water temperatures are ideal habitats for Legionella.
