There are many benefits to getting a water purifier for your home. For one, it’s a great step toward minimising your reliance on single-use plastics. It’s also a lot more convenient. The most important benefit of a water purifier, however, is that it ensures the cleanliness of the water you use for drinking and cooking.
It’s important to note that most locations in Australia have drinkable tap water. Nevertheless, it’s better to be safe than sorry when it comes to health. There are also certain places whose residents can benefit from the use of a water purifier. Perth’s water, for example, has one of the highest salinity levels in the country. This can affect the water’s taste and odour, not to mention have a negative impact on one’s health.
Which Filter Is Best for Drinking Water?
There are various kinds of water purifiers to choose from; the “best” choice depends on what you want to remove from the water. Do you want to eliminate traces of lead to prevent contamination? Are you worried about microplastics? Does your water smell too strongly of chlorine? Are there limescale build-ups in and around your faucets and sinks? There are specific water filters and water purifiers to address these concerns.
When it comes to water for drinking and cooking, your best options are activated carbon, reverse osmosis, and UV filters. Activated carbon water purifiers make use of carbon blocks, which contain thousands or even millions of tiny pores. These pores absorb contaminants such as chlorine, microplastics, lead, and sediments. Activated carbon purifiers can also remove a large number of bacteria, as well as nitrates and volatile organic compounds. To help prevent the growth of bacteria on the filter itself, some activated carbon purifiers use secondary filter media like silver.
Reverse osmosis, on the other hand, removes contaminants from the water by pushing it through a semipermeable membrane. The pressure separates contaminants like bacteria, chemicals, dissolved salts from the water and leaves them behind the membrane. However, while reverse osmosis purifiers can remove almost a large number of viruses and bacteria, they cannot do this job 100%. This is where UV purifiers come in. UV purification systems use lamps that emit a particular wavelength of UV light. This disrupts the DNA of microorganisms, which makes them unable to reproduce. The UV light also eliminates the ability of these microorganisms to function, essentially killing them.
UV water purifiers are often used together with activated carbon or reverse osmosis systems. This is because UV light can’t remove particles and chemicals. They are capable only of killing bacteria and viruses. With dual purifying systems, you can be sure that the water you drink and cook with is as clean as possible.
Which Is the Best Water Purifier for Home Use?
Some of the best water purifiers you can use at home include water pitcher filters, faucet-mounted or under-sink systems, and stand-alone units. The latter can give you either hot and cold or cool and cold water. What’s great about water filter pitchers is that they’re quite cheap. They’re also great for those who don’t need a lot of water at once, such as single-person households. Do note that water filter pitchers can’t kill microorganisms. Thus, they’re best to use when you’re more concerned about particle contaminants in the water.
Meanwhile, for larger families, faucet-mounted or under-sink water purifiers may be more useful. These filter and purify water at the source, which is why these are also called point-of-use or POU filters. If you’d rather not get your cooking and drinking water straight from the tap, you can opt for stand-alone systems for exclusive use. These often use two types of filters mentioned earlier: either activated carbon or reverse osmosis, partnered with UV lamps.
For water that you won’t be drinking or cooking with, there are more suitable filters you can use. For example, you can use an ioniser if you want to soften tap water. Also called an ion-exchange filter, this type of water filter also increases the pH of the water to more than 7. This makes the water less acidic.
The key thing to remember here is that with a water purifier at home, you won’t just get cleaner water for consumption. You’ll also gain more peace of mind when it comes to your family’s health and safety.
