Filtered or purified water: which is better for your health?

Key takeaway: purification outperforms conventional filtration by removing 99.99% of viruses and bacteria, ensuring total safety for the most vulnerable. This health-conscious choice blocks persistent pollutants (PFAS) whilst preserving your essential minerals. At an unbeatable cost of €0.02 per litre, you protect your body whilst eliminating plastic bottles for good.

Microfiltration uses 0.5-micron membranes capable of physically blocking pharmaceutical residues and heavy metals whilst preserving essential minerals. This mechanical barrier, often combined with activated carbon, radically transforms the quality of your daily drink without altering its natural richness.

However, we often don’t know whether our domestic system is actually sufficient to eliminate the viruses or persistent pollutants that find their way into our glasses. We’ll help you choose between filtered, microfiltered or purified water to ensure total health and safety in your home.

Filtered or purified water: finally understanding the technical difference

Domestic filtration removes chlorine and sediment using activated carbon, whilst purification eliminates 99.99% of viruses and bacteria. The health focus is on PFAS and microplastics, transforming tap water into a pure and economical resource. In fact, it all comes down to the fineness of the membranes.

ℹ️ The technical comparison

Microfiltration: 0.5-micron pores. Ideal for taste and sediment.
Purification: Log reduction of 4 to 6. Eliminates 99.99% to 99.9999% of pathogens.

Microfiltration to trap particles and chlorine

The 0.5-micron membranes act as a shield. They physically block sediment, rust and microorganisms. It is a truly effective mechanical barrier.

Activated carbon complements this process through chemical action. It absorbs chlorine to remove the unpleasant taste. The water immediately regains a neutral and pleasant flavour.

However, ANSES confirms that while chlorine ensures disinfection, it alters the smell. Can you see the benefit of filtering?

Purification to eliminate viruses and bacteria

A purifier must achieve a log level of 4 or 6. This means the elimination of 99.99% to 99.9999% of pathogens. This is the ultimate safety standard for your health.

Purification goes further than conventional filtration. It targets viruses, which are often too small for standard filters. It often uses reverse osmosis or UV light.

So, choose the best reverse osmosis system. It’s the solution for total home purification.

Why treating your water is a major health step

Beyond the technical aspects, it is the direct impact on your body that justifies installing a high-performance system.

Say no to PFAS and pesticide residues

Forever chemicals, or PFAS, never break down naturally. Only fine filtration using activated carbon or reverse osmosis can effectively capture them.

⚠️ Health Alert

PFAS are persistent, microplastics accumulate, infants are vulnerable

In fact, microplastics accumulate in water systems and threaten our gut health.

Pesticides seep into groundwater. Filtering at home drastically reduces this daily chemical exposure.

Retain magnesium and calcium without the limescale

It is important to distinguish between demineralisation and selective filtration. Some systems remove everything. Others retain the magnesium and calcium essential for your balance.

Filtered water remains a source of nutrients. It hydrates without overloading the body with limescale.

Filtered water preserves essential minerals whilst removing impurities that are harmful to long-term health.

Greater safety for infants and the elderly

Infants’ kidneys are highly sensitive to nitrates and metals. Pure water is essential for their growth.

For baby bottles, use a certified system that guarantees total microbiological safety.

A simple solution, requiring no installation or electricity.

Filtering your water: a healthy and eco-friendly daily habit

Cost-effectiveness and sustainability: say goodbye to plastic bottles

As well as protecting your health, filtering your water can make a huge difference to your budget and your environmental footprint.

Cost analysis compared to bottled water

The initial investment in a filtration system may seem high. However, this choice replaces hundreds of packs of plastic bottles every year. It’s a winning proposition in the long run.

Water source Cost per litre Annual waste Convenience
Bottled water €0.30 High (kg of plastic) 2/10
Filter jug €0.05 Moderate (cartridges) 6/10
Under-sink osmosis unit €0.03 Low (membranes) 9/10

The price per litre of treated water often falls below three cents. Compared to the high street, it’s simply unbeatable.

The environmental impact of a sustainable system

Choosing stainless steel is a major decision for the health of the planet. Gravity-fed systems use corrosion-resistant tanks. Above all, this prevents the leaching of bisphenols associated with disposable plastic.

đź’ˇ Positive environmental impact

  • Massive reduction in plastic waste
  • Fewer lorries on the roads
  • Energy savings in manufacturing
  • Durability of stainless steel filters

Reducing your carbon footprint becomes a simple daily habit. Less transport means fewer CO2 emissions. You’re taking concrete action for the planet right from your kitchen.

A practical guide to choosing and maintaining your filter

To enjoy these benefits in the long term, you need to choose the right equipment and adopt the right maintenance habits.

Choosing between a jug, gravity-fed or under-sink filter

First, assess the capacity you need based on the size of your household. A jug filter is more than enough for a single person. On the other hand, a large family will prefer a gravity-fed system or a reverse osmosis unit.

Next, compare how easy each system is to install. Some models simply sit on your worktop. Others require a technical connection under the sink to work.

Cleaning and changing the filter: the schedule

Learn to spot the signs of wear and tear on your equipment. A slower flow rate or a change in taste should be a warning sign. You must then replace the cartridge without delay to protect your health.

đź’ˇ Expert tip

Clean your reservoirs with soapy water every month. Avoid direct sunlight to minimise algae growth. Replace the seals if necessary to maintain a watertight seal.

Thorough maintenance prevents the build-up of limescale and bacteria. Check the water level regularly to ensure there is no debris visible in the tank.

Regular maintenance guarantees pure water and extends the lifespan of your health investment.

Choosing filtered or purified water removes 99.99% of pollutants and PFAS whilst preserving your essential minerals. Save hundreds of euros today by switching from plastic to a sustainable and healthy solution. Protect your health and the planet: switch to home filtration for unrivalled purity with every sip.

FAQ — Filtered or purified water

What is the practical difference between microfiltered water and purified water?+

Microfiltration is a highly effective mechanical barrier, often using 0.5-micron membranes combined with activated carbon. It traps sediment and heavy metals and removes the taste of chlorine whilst retaining valuable minerals such as calcium. It is the ideal solution for improving your daily drinking experience.

Purification goes even further by aiming for total microbiological safety. It uses technologies such as reverse osmosis or UV to eliminate up to 99.99% (log 4 standard) or even 99.9999% of viruses and bacteria. It is the ultimate standard for protecting the most vulnerable, particularly infants and the elderly.

Is an activated carbon filter really effective against forever chemicals (PFAS)?+

Activated carbon is a weapon of choice, but let’s be clear: its effectiveness is not absolute for all 11,800 compounds in the PFAS family. It excels at capturing long-chain molecules, but ultra-short chains, such as TFA, can sometimes slip through the net.

For optimal protection, we recommend using high-quality activated carbon (often derived from coconut shells) and strictly adhering to the contact time with water. For a more thorough removal of these chemical residues and pesticides, reverse osmosis remains the most effective technology.

Is it really more cost-effective to filter your water rather than buying bottles?+

The maths is simple and your wallet will thank you! On average, bottled water costs between €0.50 and €1.50 per litre, which amounts to an annual budget of up to €1,500 for a household. In contrast, a filtration solution such as the Pureva system costs just €0.02 per litre.

Even when you factor in the initial investment in a quality system, you’ll generally save over €200 in the first year alone. As well as the financial benefits, you’ll say goodbye to the hassle of lugging around water bottles and drastically reduce your plastic waste. It’s a win-win for your health and the planet!

How do I know when it’s time to replace my filter cartridge?+

There are several tell-tale signs: if you notice the water flow slowing down or if the taste of chlorine starts to reappear, your filter is reaching saturation point. Regular maintenance is essential to prevent bacterial growth and ensure your water remains perfectly safe.

We recommend noting the replacement date on your calendar or following the indicators often found on jugs and purifiers. A quick monthly clean of the tanks with soapy water and changing the cartridge in good time will extend the life of your appliance and protect your health in the long term.

Is filtered water suitable for preparing baby bottles?+

Absolutely, but you must choose the right system. Infants’ kidneys are extremely sensitive to nitrates and heavy metals. For complete safety, opt for a purifier specifically designed to remove nitrates, which not all standard filters do.

Using a certified purification system guarantees water free from microbiological and chemical impurities, providing a healthy foundation for your baby’s growth. It is a reassuring and eco-friendly alternative to bottled water, which is often stored in variable conditions.
