The health benefits of water purification and water filtering are undeniable.
But the most obvious benefit is the ability to clean water and reduce the risk of infections, according to Dr Richard Kost.
“The main reason for using these tablets is to remove water contamination,” he says.
“It can also remove the toxins in water, which can also help to reduce the risks of developing some of the other common infections that occur when you drink water.”
Dr Kost recommends you use your tablets as directed.
They should be taken every day for a minimum of three days, and you should continue to take them for a maximum of three months.
But you should not take a water purifier, he says, because that can cause water to become contaminated.
“If you use a purifier you should only take it for a short period of time, and then you should stop,” he advises.
The water purifiers are generally made by a company called Red Cross, and the tablets are manufactured by a different company called AquaPure.
“Red Cross is an international company, so they have a very good reputation in the water purificating industry,” Dr Kast says.
It is a common misconception that water purifies, but Dr Kest says this is simply not the case.
“When you’re using the water filters or the water filtering, they are designed to remove the water from the water source.
If you remove water from a source, it is just going to get in there, and that is the water that is going to cause the infection,” he explains.
But Dr Kstad says that while there is some good evidence that water can be filtered, it does not remove all of the toxins from the surface of water.
“So if you are using a water filter, that is really only going to remove one of the three or four toxins, and if you don’t get rid of those toxins, the bacteria will be able to get back into the water and do something else,” he adds.
“That is a very different issue from water purifications, and I think that’s why we don’t really know what is going on.”
Water purifiers can also reduce the chances of getting a waterborne illness, but there are some important caveats to take into account, Dr Kiest says.
The best way to ensure that your water is safe to drink is to use a good quality filter.
“Water purifiers filter out about 60 per cent of the contaminants in the system, so it really doesn’t matter how many times you use them,” he notes.
“You should use one of those that are made by Red Cross or AquaPure, because those are the ones that have the most stringent standards for quality control and testing.”
Dr Red Crayton from the Australian Institute of Water Technology says that the biggest reason for not using water purify tablets is because they can be quite expensive.
“We know that some of these tablets are very expensive, so a lot of people are looking to buy them on eBay, because they’re very difficult to get hold of,” he said.
“They have to be taken for at least three days for the tablets to be effective, and it can be several weeks after that for the water to be safe to use.”
But you should always take the tablets as instructed.
They will reduce the number of bacteria that get in the tap and they will also reduce any contamination that may be left in the drinking water.
“Water purifying, water filtrating, and disinfecting tablets are available from pharmacies, health clubs and water supply companies.
