Lovia Spa, a well-known brand under Guangzhou Huantong Industrial, recently released three innovative hot tub products: 3-person mini hot tub small plug and play jet bathtub, home and garden spa hot tub and whirlpool hot tub.

A swim spa hot tub should never be operated without a filter. The lack of a filter will cause pump blockage, heater contamination, and nozzle clogging, resulting in irreparable mechanical damage; furthermore, deteriorating water quality will accelerate bacterial growth, affecting human health.

When the nozzles of a swim spa hot tub spray water at high speed, the strong water turbulence entrains air into the water, forming numerous tiny bubbles. If these bubbles combine with surfactants, they form a stable foam layer on the water surface.

Most whirlpool spa hot tubs use chlorine for disinfection. Chlorine's primary function is to kill bacteria and algae, but it is also a strong oxidizing agent. Chlorine damages the hair's cuticle structure, stripping it of its natural protective oil layer.

Mixing chlorine and bromine does not simply add up the disinfection effects; rather, it produces a complex chemical reaction. Free chlorine in the water will partially convert to free bromine (HOBr). Chlorine has a fast disinfection speed but a short lifespan, while bromine has high stability but a slow disinfection speed. Mixing chlorine and bromine can lead to unstable disinfectant efficacy.

Most whirlpool spa hot tubs maintain a temperature of around 37°C to 40°C. While this temperature range is ideal for human muscle relaxation, it presents an unfavorable environment for viruses. Many common viruses (such as influenza viruses, coronaviruses, and enteroviruses) are rapidly inactivated in high-temperature environments.

A water temperature of 40°C (approximately 104°F) is close to the upper limit of what the human body can safely tolerate. According to industry standards for hot tubs, most manufacturers recommend a safe water temperature of 38°C to 40°C. Exceeding this range, especially with prolonged soaking, poses potential health risks.

Swim spa hot tubs are inherently energy-intensive devices. If a swim spa hot tub is left on all night, the heater still needs to maintain a constant water temperature (usually between 36°C and 38°C), which means continuous energy consumption.

Many spa hot tub users believe, "I've already added bromine, so I don't need to worry about the water quality anymore," which is a common misconception. In fact, bromine only maintains continuous disinfection, while shocking is a necessary step in periodically "resetting" the water quality.

Testing the pH Level. Refilling a whirlpool spa hot tub may seem like just changing the water, but in reality, the water composition can differ each time it's filled. Tap water, well water, or filtered water have significantly different mineral and carbonate content, all of which directly affect the water's pH balance.

The main component of bleach is sodium hypochlorite (NaClO), a strong oxidizing agent commonly used for sterilization, bleaching, and stain removal. While it is effective at eliminating mold and bacteria in a home environment, its use in swim spa hot tub components can pose potential risks.

If you use a swim spa hot tub primarily to relieve work stress or improve sleep, 2-3 times a week is sufficient for optimal results. Each session should last 20-30 minutes, with the water temperature maintained between 36-38℃. This relaxes muscles without causing excessive fatigue.
