You can keep your cold plunge device clean and sanitized with either UV light or ozone filtration systems. Most of the time, this is an overlooked item by people who buy the tub, but for those that want to make sure they get the most out of their money, those that like to dig in the weeds, or those who may want to build their own, this topic is important. In this article, we will analyze uv light vs ozone filtration systems for cold plunges.
UV Light Filtration for Cold Plunges
An Ultraviolet (UV) water filtration system is a system that disinfects water by using germicidal UV. UV systems have a chamber that allows water to flow through it. Inside the chamber, light is emitted (at a UV wavelength) that deactivates any living organism that is in the water supply so the water stays clean.
UV Light filtration is a popular method to sanitize cold plunges by many top companies that manufacture the devices (Odin Cold Plunge). The UV light is usually installed with the plumbing system of the cold plunge and is turned on when the water starts to circulate.
What is UV Light System?
UV stands for ultraviolet. UV light is produced by a bulb that has a wavelength of light that disinfects the water is in contact with. The UV light deactivates living organisms so they cannot reproduce
How Does it Work?
A UV Light filtration system works by exposing living organisms, like bacteria or viruses, to an ultraviolet wavelength that scrambles the DNA of the organisms. They can no longer reproduce or make you sick.
Does a UV System Require Maintenance?
UV systems do need maintenance. There is no water filtration system out there that won’t need a little bit of checking in. Regardless of the option you end up going with you will need to keep things up to date to make sure nothing goes wrong with the investment you made into your cold plunge device.
From what it looks like, most UV systems only require that the UV lamp to be replaced once a year. Typically, the mercury that fuels the lamp last about 375 days (or about 9,000 hours) if you run your cold plunge 24/7 (which most high-end tubs do anyways).
When buying a cold plunge be sure to reach out to the companies that ship to make sure you understand the maintenance it may need.
O-Zone Filtration for Cold Plunges
O-Zone filtration is another method used by many cold plunges on the market for keeping water inside the tub clean and sanitized. This method works by using ozone (a form of oxygen) to kill bacteria and other living organisms that may be found in the water.
How Does it Work?
Ozone is usually generated by an ozone generator which is installed in the plumbing system of the cold plunge. An ozone filtration is an effective and less expensive option to go with if you plan on building your own cold plunge. Typically, when you are buying a premade plunge, the difference in systems is not really an option to choose from.
Everything to Know About Micron Filters
Micron filters, also known as microfilters or microporous filters, are essential devices used for the filtration of liquids and gases. These filters are designed to remove particles and contaminants from a fluid stream based on their particle size. The term “micron” refers to the unit of measurement used to quantify the size of particles a filter can capture. One micron is equivalent to one-millionth of a meter.
These filters are commonly used in various industries, such as water treatment, pharmaceuticals, food and beverage, automotive, electronics, and more. In water purification systems, micron filters help remove sediment, dirt, bacteria, and other impurities, improving the water’s quality and safety.
The effectiveness of a micron filter is determined by its micron rating. For example, a filter with a 5-micron rating can capture particles as small as 5 micrometers in size. The smaller the micron rating the better the filter is at catching those pesky particles that end up in the water.
Which Method is Best for Your Cold Plunge?
Unless you plan on building your own cold plunge, the filtration system is not really a big deal breaker in our opinion. If you had to choose the “less costly option” we would say to go with the ozone.
For most tubs on the market, UV light filtration is an add-on, many of the most popular tubs use ozone. Out side of that initial cost, the only recurring cost that is associated with UV light filtration is the replacement of the lamp once a year.
While ozone is labeled as the more affordable option, ozone filters may require a little more maintenance on your end. Either way, they both are an effective way to filter and keep water inside your cold plunge clean and sanitized.
