A chlorinator is a tool used to filter the pool of pollutants by sanitizing the water with chemicals like chlorine and bromine.

Why use a chlorinator?

Swimming pools, if not cleaned regularly, can be infested overtime with pollutants and other harmful materials such as viruses, bacteria, and algae. Moreover, sweat, urine and excretion substances of swimmers can also contaminate the water with detrimental products such as urea and ammonia.

Presence of such substances in water can be proved hazardous to humans and are linked with diseases such as diarrhea, norovirus, skin infections, allergies, and itching. 

Luckily, we have pool cleaning robots & chlorinators to battle these conditions. A chlorinator uses chlorine and some portion of bromine to kill the bacteria present in water. The chemical effects of chlorine are useful to sanitize the water by defusing the harmful substances. Let's have a brief look at how a chlorinator works.

For whom is chlorinator for?

A chlorinator is for every individual who prefers a safe, reliable and easy control of their pool filtration and chlorination. From high-end swimming pools and Jacuzzis at hotels, pools for professional swimmers, to the normal pools at homes, all are best used with a chlorinator. It is one of the most advanced yet convenient methods for pool water cleansing suitable for people from every walk of life.

How does a chlorinator work?

A chlorinator works along with the pool filtration system by automatically releasing the right amount of chlorine and other pool cleaning chemicals into the pool water. We have to manually fill the chlorinator with the cleaning substance. However, the rest of the work is done automatically by chlorinator. The pool filtration system is attached with the chlorine feeder. The chlorinator then injects the chlorine into the water when desired by the process called chlorination. You can manually set the amount and rate of chlorine to be added.

Chlorine, when introduced to the water, undergoes a chemical reaction by splitting into hypochlorous acid. This acid has a mechanism to kill the microorganism present in water by targeting the lipids in their cell walls. This destroys the enzymes in the cell and collapses the cell structure, thus neutralizing the harmful agents. 

How to use a chlorinator?

Using a chlorinator is as easy as it comes. By following the five simple steps given below in order as they are stated, your chlorinator will do what it is supposed to.

Step 1: Install the chlorinator to the swimming pool. Your chlorinator comes with a user manual or a guide on how to install it properly. Remember the chlorine feeder is supposed to be attached with the filtration system.

Step 2: Open the chlorinator feeder to add chlorine. Turn off the feeder control valve to exhaust the feeder from any water. After one minute remove the feeder cap but make sure not to stand too close to the feeder.

Step 3: Next we need to fill the feeder with the cleaning product. You can use any cleaning substance such as chlorine tablets/sticks, bromine or any other you find suitable. Some chlorinator models can handle all substances while some are limited to intake specific ones. So make sure to find the best chlorine tablet for the model you own.

Step 4: Close the feeder cap tightly. Also, make sure to look for any leakages or wears in the line. Turn on the power supply.

Step 5: Configure the chlorinator with the amount of cleaning substance you wish to add into the water. If your model allows, also set the dissolving rate for chlorine. 

Safety precautions

  • Always remember to turn off the power supply before filling the feeder for safety.

  • Timely inspect the lines and valves for any leakage or wear. If needed, repair or replace the lines.

  • Do not inhale the chlorine fumes.

Bonus tip

  • It is best to use the cleaning substance that is most compatible with your model of chlorinator as suggested by the company.

Benefits of chlorinator

A chlorinator comes with a bundle of benefits that enhance its worth. Due to its ergonomic design, durable action, and convenient usage, it is considered as the best source for pool cleaning. For the same reason, it is widely preferred by the majority of the audience and is most common in high-end swimming pools around the world. However, here are the topmost prominent benefits that a chlorinator offers to its users.

However, a chlorinator provides you an exception to that. It offers a purely automatic system where you only need to press the button and forget while the chlorinator efficiently injects the chlorine into the water. It is a more hygiene and secure method.

Reliable and advanced

A chlorinator has a highly developed yet easy-to-use interface that allows controlling the device by a press of a button. In this regard, you can set the amount of chlorine to add and also the rate at which the chlorine dissolves into the water. Its entire design is highly ergonomic with the efficient working of tools, lines, and vales, which makes it convenient for a person to use. 


Chlorinators are simple gadgets that omit the use of any complex electronic or mechanical structures. They require low maintenance and the replacement of lines and hoses is required only after a year or more of use. They ensure cost-effectiveness in a sense that you only need to pay once and enjoy the rest of the days relaxed instead of adopting other unreliable methods that timely utilize your hard-earned money for repairs or replacements.

Last but not least, chlorinators ensure a strong action against the pollutants and disinfectants with durable effects. Their effect could last for days due to far-reaching action of automatic chlorine feeder. As a result, you get clear and sanitized pool water safe for you and your family.

Drawbacks of chlorinator

Although a chlorinator offers a lot of benefits there are some also some disadvantages linked with it. 

  • Opening the feeder lid requires strength and can be challenging for some individuals.

  • Chlorine fumes emit from the feeder which can be dangerous.

  • The chlorine dissolving rate can be confusing.
