Buyer’s Guide For Best Chlorine Tablet for Drinking

The best way to purify water is by boiling it if you live near a source of heat. If not, we recommend chlorine tablets. Chlorine is used to kill the bacteria and other microorganisms that may be in the water, so don’t forget to carry at least one chlorine tablet with you when you’re hiking or backpacking. 

If you are looking to buy a chlorine tablet, here are the factors to consider:

Amount per Tablet, or Parts Per Million (PPM)

A general rule of thumb is two tablets for every liter of water, but the amount can vary depending on what you’re using it for, and how many people are drinking. Make sure to check the amount before buying a package of chlorine tablets.

Chlorine Tablet Size

Some chlorine tablets come in large sizes, which you can break down into smaller pieces. If you’re hiking or backpacking, try to find tablets that are light and easy to carry around.

Chlorine Form

You can find chlorine tablets in liquid form as well. Some people prefer the solid because they are easier to use, while others may opt for pouring the liquid form.

Storage Conditions

If you’re using chlorine tablets, make sure to store them in a cool place – don’t put them anywhere where they could get wet or moist! Check that the lid is tightly closed so no bugs can get inside your tablet container. 

Brand Name & History

You should only buy chlorine tablets from a trusted company that guarantees good quality products.

Price

Lastly, set a budget. Chlorine is pretty common so there are tons of brands to choose from and with different price points. Go for something affordable, especially if you are new to using them. 

Efficacy

Did you know that some water purification tablets are only effective against bacteria, while others also kill viruses? Make sure to buy the right kind of chlorine tablet for your needs.

Tablets vs Drops

You can choose between using chlorine tablets or drops. Some people prefer tablets because they’re easier to use and require little to no mixing, but other people prefer drops because they’re lighter and more compact.

Usefulness

If you live near a source of clean water, then you don’t have to worry about purifying it before drinking. But if you’re hiking or backpacking, chlorine tablets are a must! They kill the microorganisms and allow you to drink water safely.

Carry Them in a Plastic Bag

If you’re using chlorine tablets, make sure to carry them in a resealable plastic bag, so they are protected against moisture and other contaminants. In addition, if they accidentally get smashed or broken, the tablets won’t mix with your dry foods. 

FAQs For Best Chlorine Tablets

Are Chlorine Tablets Safe for Drinking Water?

Chlorine tablets are safe for drinking water and they’re one of the most popular methods to purify water from home. Remember to watch the chlorine levels, because they can irritate your throat and stomach. 

Some people prefer liquid chlorine tablets because it’s easier to carry around when going on a hiking or backpacking trip. Do not store them in a humid environment, keep them closed up tightly, and remember to read the expiration date each time before using a new batch!

Which Chlorine is Best for Drinking Water?

When it comes to chlorine, you want to buy tablets with both sodium hypochlorite and calcium hypochlorite. This is the safest type of tablet for drinking water, as it stops both bacteria and viruses in their tracks. Avoid unstabilized chlorine tablets.

What Dosage Should I Use?

All you need is two tablets per liter of water. Do not use too many tablets, because it can irritate your throat and stomach.

What is the Shelf Life of Chlorine Tablets?

Chlorine tablets have a shelf life of about 6 months when stored at room temperature. After this time, they usually start to discolor or lose their effectiveness. Make sure you check for an expiration date before using a new batch.

How Long Does Chlorine Stay in the Water?

It takes about 30 minutes to disinfect a liter of water with chlorine tablets. Just make sure not to store it for too long, and if you’re using the water for cooking or drinking then wait at least an hour before consuming any water that has been purified. Also, remember that chlorine only kills the microorganisms in the water, so you should still boil or filter it before drinking.

Is Chlorine Only Used for Drinking Water?

Chlorine can be used for more than just drinking water. 

For instance, chlorine tabs can also be used to keep a swimming pool clean. Automatic chlorine dispensers can be used for the release of granular chlorine and maintaining the chemical balance of gallons of pool water.

Pool size is a major determinant as to what level of chlorine or extra chemicals should be added to a body of water. Larger pools will require greater amounts of chlorine concentration and a greater level of distribution of chlorine.

The release of swimming pool chlorinating tablets into the swimming pool water helps to achieve chemical stability and long-lasting protection. An adequate dose of chlorine also provides close to maximum safety against the growth of bacteria and the growth of algae.

What is the Difference Between Drinking Water Chlorine and Pool Chlorine?

Chlorine tablets are used to purify drinking water while pool chlorine tablets are engineered specifically to circulate in outdoor pools. Pool tablets are often 3-inch tablets or liquid chlorine paired with pool skimmers and filters. Tablets are generally better than liquid chlorine for pool waters because of chlorine loss, although unstabilized chlorine tablets degrade faster and are better for an indoor pool.

Do Chlorine Tablets Make Water Taste Bad?

You can minimize the chlorine smell and taste by using a couple of drops of lemon juice, which helps to balance out the flavor. When purifying your water, make sure to use a clean bottle, otherwise, it can mix with the smell of chlorine.

How do I Store Chlorine Tablets?

Always store your chlorine tablets in a plastic bag or other airtight containers. If you don’t, moisture and other contaminants may get into the bottle, which can ruin them before their expiration date. It’s also important that you keep them out of the sun or any other heat source, or they can break down even faster.

How Much Chlorine Do I Need for 1000 Litres?

You need about 1.5 kilos of chlorine for 1000 Litre, but it depends on the quality of the tablets you’re using! Make sure to check the user manual that comes with your specific brand before buying or preparing them for drinking water.

Which is Better: Iodine or Chlorine?

Both iodine and chlorine are effective in purifying water, but iodine is better at killing viruses. Chlorine only kills the bacteria in your water, which means you should also boil it before consumption or use a carbon filter to get rid of any potential viruses.

Do Chlorine Tablets Keep the Water Clear?

No, you won’t be able to keep the water clear with chlorine tablets. The best way to purify your water is by boiling it before consumption, but if you don’t have the time then using a carbon filter will also remove any contaminants.

Are Aquatabs Bad For You?

There have been no known side effects from using Aquatabs, but it’s always a good idea to consult your doctor before taking any new medication. They’re also only designed to kill bacteria and viruses, so you should still boil or filter the water before consumption.

Can we drink chlorinated water?

Yes, you can drink chlorinated water.

What Are the Disadvantages of Chlorine?

Chlorine has the potential to discolor clothing and has a strong smell that can irritate your throat and stomach. If you plan on using chlorine tablets for water purification, use them in moderation and store all of the filtered or purified water in a clean container.

What Are the Side Effects of Excessive Chlorine?
