In the world of water filtration, the effectiveness of a filter is often measured in the size of the filter. In this guide, the experts at Billi will answer common questions like: “How many microns is a good water filter?” and compare what a 5-micron filter removes to a 0.5-micron filter or smaller.
Applying over 30 years of water filtration expertise, Billi can help you understand the different micron filtration levels in water filters, what they mean and what they remove. Keep reading to learn the differences or contact us today for more information.
Are Water Filters Effective?
Water filters can be effective in filtering out a number of chemical and organic elements, plus they can make substantial improvements in odour and taste.
But as consumer magazine, Choice notes, you should always look for certification in any water filtration system.
At Billi our premium filters boast the Australian Standards WaterMark for product safety and consumer confidence to ensure you and your family have the highest level of drinking water available.
Plus, we offer a multistage filtration system – which utilises BWT’s unique Fibron X® technology. This system:
- filters out particles
- reduces chlorine and organic chemicals
- removes parasitic cysts giardia and cryptosporidium (0.2 Micron filter only).
Understanding Micron Ratings
A micron, short for micrometre, represents one-millionth of a metre. The micron rating of a filter indicates the size of the particles it can capture. Put simply, smaller micron numbers mean finer filtration, catching smaller particles and providing cleaner water.
What Does a 5-Micron Water Filter Remove?
Generally speaking, the smaller the micron number the better. Try imagining microns like a sieve. A 5-micron water filter will sieve out particles that you can see – but all the other smaller particles will pass through it into your drinking water, though in the case of Billi’s advanced filters 5 Micron Filters can also remove some common chemicals like chlorine. This level of filtration is particularly effective in improving the taste and clarity of your water, making it a standard choice for many households and businesses.

Are Finer Filters Necessary?
The answer depends on your water source and how important hygiene and peace of mind are to your work or business, for example looking at what a 1-Micron Filter removes compared to a 5-Micron Filter actually shows a significant increase in the filtration capability. This finer filter can catch particles invisible to the naked eye, making it suitable for those who want a higher level of water purity. However, it is less effective at reducing heavy metals, or parasitic cysts like giardia and cryptosporidium. For those contaminants, even smaller filters are recommended.
Sub-Micron Filtration: What Do 0.5 Micron Water Filters Remove?
For those concerned about lead, heavy metals, and parasitic cysts such as giardia and cryptosporidium, a sub-micron filter is advisable. A 1 or even 0.5 Micron water filter reduces quite a lot – but even smaller than the 0.5-micron filter, is Billi’s premium 0.2-micron filter which can:
- Filter out particles in the water
- Reduce chlorine and organic chemicals
- Remove parasitic cysts giardia cryptosporidium and;
- Reduce heavy metals.
What Makes Billi’s Filtration Great?
Billi’s partnership with BWT, Europe’s largest water treatment products company, allows for filters with unique Fibron X technology. This ensures a graded density profile, resulting in superior contaminant reduction performance and capacity. Whether you need a 5-micron water filter or ultra-fine 0.2-micron-filtered water, Billi has a solution that fits your needs, backed by a commitment to innovation, quality, and sustainability.

What Do Billi’s Tap Water Filters Remove?
Our filters contain a multistage filtration system which includes a cyst filtration layer, a core and a post-filtration layer that traps fine particles. Specifically, Billi’s filters:
- Remove particles in the water
- Remove parasitic cysts (0.2 Micron only)
- Reduce heavy metals (0.2 Micron only)
- Reduce chlorine and organic chemicals
Our filters also enable minerals to travel through the appliance without allowing any scale to build. Find a Billi that suits you.
Differences Between Our Micron Filters
Traditional cartridge filters are low cost and easy to change however they do have shorter life spans as particles plugs their pores within the cartridge membrane. A micron filter is able to capture smaller particles and more of them compared to traditional filters due to the higher surface area of the filter.
The 5 micron filter is very effective at capturing particles, providing you with cleaner, higher quality drinking water. Because particles are trapped throughout the filter rather than just the filter surface, it provides a more effective level of filtration that is also maintained for longer – the filter surface doesn’t get blocked and water pressure is maintained which provides a higher flow rate.
Submicron filters such as a 0.5 micron water filter or the more advanced 0.2 micron water filter have further filtration capabilities as the smaller openings are able to filter more, including bacteria. Our water filters are available in the following three options – HSD and 0.2 & 5 micron filters.
Choosing the Right Micron Rating
Determining the right micron rating for your water filter depends on several factors, including your water source, the contaminants present, and your specific needs. Here’s a simple guide to help you choose:
- Assess Your Water Source: If you are using municipal water, a 5-micron filter might suffice to remove visible particles and improve taste. However, for well water or other sources that might contain more contaminants, a finer filter could be necessary.
- Identify Contaminants: Knowing the specific contaminants in your water is crucial. For instance, if you are concerned about chlorine, a 5-micron filter from Billi will help. For parasitic cysts, you’ll need a filter with a rating of 1 micron or finer.
- Consider Usage and Health Concerns: If water purity is a top priority for health reasons, such as in a home with young children or hospitals and aged-care facilities with immunocompromised individuals, opting for a sub-micron filter (0.5 microns or less) ensures the highest level of filtration.
- Consult Experts: For personalised advice, consulting with experts like those at Billi can help you determine the best filter for your needs. They can provide insights based on your specific circumstances and the latest filtration technologies.

When you’re focused on your health & well-being and playing sports, you want to make sure that what you put into your body is going to aid your performance. Staying hydrated is important when it comes to playing sports but are sports drinks good for you? Below we look at whether sports drinks are healthy and what some great alternatives to sports drinks are.
Billi has been at the forefront of the instant filtered boiling and chilled water systems industry for over 30 years. All our water filtration systems come with an assurance of quality, innovation & sustainability and are proudly Australian-designed & made to strict quality standards in our state-of-the-art facilities in Melbourne. If you’re looking for healthy ways to stay hydrated, here are the facts about whether sports drinks are healthy along with our recommended alternatives to sports drinks.
The Truth About Whether Sports Drinks Are Healthy
Whilst the main ingredient of sports drinks is water – they often have other substances added to them such as carbs (e.g. sugars) and electrolytes (e.g. sodium and potassium). Whilst there has been some research done on the effectiveness of sports drinks, the validity of these studies has been questioned and the findings are often inconclusive.
And, with these added extras in sports drinks, excessive consumption could potentially lead to weight gain, diabetes, high blood pressure and other medical issues.
Sports drinks may be a good option for recovery after one-off intense physical activity however, eating a healthy balanced diet and drinking water regularly is usually sufficient for replenishing your electrolytes when it comes to most physical activities.
Alternatives To Sports Drinks
Because water makes up most of our body weight and is important for ensuring our bodies function properly, we need to ensure we replace water lost through sweat and exercise. Drinking water regularly promotes better health and also sports performance. Many studies show that water is best for staying hydrated so when it comes to alternatives to sports drinks, good old water is the smart choice.
Drinking water as an alternative to sports drinks will help to maintain muscle function, prevent muscle cramps, replace fluids lost during your physical activity and also helps to regulate your body’s core temperature.
Our water filtration systems are ideal if you want to drink water as an alternative to sports drinks.
With instant filtered chilled, still or sparkling water on tap, it makes it easier to consume high-quality water that promotes your health & well-being. If you’re drinking water regularly you want to make sure the water you’re putting into your body is good for you. Our filters remove the following from your water:
- Chlorine
- Parasitic cysts (including cryptosporidium & giardia)
- Heavy metals
This filtering process also improves the taste and odour of your water which will also entice you to increase your water intake & stay hydrated too.

Below we will address the following topic: how to find a water filter service company near me.
Why and When is Servicing Important?
Like cars or other precision machines, Water Filters require regular servicing to ensure optimal performance. Whilst you may not be able to notice a change in taste or water quality immediately, frequent servicing still provides peace of mind that you’re drinking safe water. Additionally, servicing and replacing of filters helps extend the lifetime of the system as a whole, this is why we recommend servicing at least annually.
Moreover, water filters operating in high-volume commercial settings or areas with heavy sedimentation in the water supply might require servicing on a more frequent basis. This proactive maintenance ensures that water quality stays top-notch, and the system functions at peak capacity and reduces the likelihood of costly repairs down the track.

Making seltzer at home is not only cost-effective, but by minimising single-use plastic bottles it is much better for the planet. Below is the best way to make seltzer at home along with some easy recipes to make flavoured seltzer at home.
Billi has been at the forefront of the instant filtered boiling and chilled water systems industry for over 30 years. All our water filtration systems come with an assurance of quality, innovation & sustainability and are proudly Australian-designed & made to strict quality standards in our state-of-the-art facilities in Melbourne. If you’re looking for the best way to make seltzer at home, here is how.
What Is Seltzer?
What seltzer water is, is simply just water, carbonated with carbon dioxide to make it bubbly… so, essentially, seltzer water is just another term for sparkling water. Seltzer water is a term most often used in America, whereas here in Australia most refer to it as sparkling water. Seltzer water has gained in popularity as it can be a healthy alternative to soft drinks and many find it much more refreshing than still water – so it can help increase water intake.
Enjoying Seltzer Water On Tap In Your Own Home
Because the seltzer water is filtered through our high-quality filtering systems, it not only tastes great but all the nasties like chlorine, parasitic cysts including cryptosporidium & giardia are removed. Our filters have also been designed to enable minerals to still filter through whilst preventing limescale build-up. Our water systems are energy efficient and include innovative features such as adjustable chilled temperature and sparkling level so you can have your seltzer water as bubbly as you like it.
The Best Way To Make Seltzer At Home
If you’re keen to have refreshing seltzer water at home, the best way to make seltzer at home is with our water filtration systems. In our range, we have two models that provide high-quality seltzer water:
- Billi Home CS – (dual-levered slimline dispenser with chilled & sparkling water)
- Billi Home BCS (XL levered dispenser with boiling, chilled and sparkling water)
Our systems are the best way to make seltzer at home because you can enjoy instant seltzer water that tastes great, on tap whenever you feel like it. And, because the water runs through our high-quality water filters before it is dispensed through the dispenser, you have the best quality drinking water with chlorine and parasitic cysts (including cryptosporidium & giardia) removed. The filters also still allow minerals (the good stuff) to filter through whilst preventing limescale build up too.
Our water systems are energy efficient and because you’re minimising single-use plastic bottles, this is a much more environmentally friendly way to have seltzer water at home. And, because our systems are under bench, you don’t have to worry about your bench top or pantry being cluttered with a manual seltzer water machine and you also don’t have fridge space taken up with bottles of water.
Another reason using our systems is the best way to make seltzer at home, is that they also include innovative features such as adjustable chilled temperature and sparkling level so you can have your seltzer water as bubbly as you like it.

Make Flavored Seltzer At Home
With our water filtration systems, it’s easy to make flavoured seltzer at home. Here are some simple, healthy and easy recipes to make flavoured seltzer at home:
Ginger, Lime & Mint Flavoured Seltzer Water
To make this healthy delicious flavoured seltzer water simply fill a jug (or a bottle with a lid to retain the fizz) with seltzer water. Then add a knob of peeled and finely chopped ginger, sliced lime and a handful of fresh mint leaves. Let it sit in the fridge for a few hours for the flavours to fuse, then enjoy!
Berry Bliss
Add your favourite, in-season berries to the bottom of a glass. Make sure they are nicely ripe so they are sweet and not too tart (unless you like a bit of tartness!). Add in some sliced orange then squash all the fruit so all the juices and flavours are released. Add your seltzer water and a slice of orange as a garnish, then sip away.
Apple Chai Seltzer Water
Brew your favourite chai tea in a cup (you may want to use two tea bags for a stronger flavour). Once it’s chilled, add to a tall glass with half an apple finely chopped. Top up with your seltzer water, add a couple of teaspoons of honey if you like it sweet and voila!
