Is a Water Purifier Really Necessary?

Access to healthy, safe and clean drinking water is not a luxury today, but an indisputable basic need. Factors such as increasing urbanisation, fluctuations in reservoir levels and ageing infrastructure systems are giving rise to legitimate concerns about the quality of the water flowing from our taps. It is precisely at this point that a critical question arises in the minds of consumers considering an investment for their home or office: is a water purifier really necessary? Growing mistrust of tap water, the unstoppable rise in the price of bottled water, and the adverse effects of plastic packaging on human health make it essential to analyse the answer to this question in detail. In this guide, we will examine, in the light of scientific facts, whether investing in such a system is a sensible decision from both a biological and an economic perspective.

The Truth About Tap Water Quality and Consumption in Turkey

Across Turkey, the tap water infrastructure varies considerably from province to province and region to region. Although water from dams is disinfected in treatment plants in accordance with international standards, the process by which this water travels through kilometres of pipework to reach the tap in our homes carries a serious risk of contamination. According to TÜİK data, daily per capita water consumption in Turkey has reached approximately 255 litres. Given such a high level of consumption, ensuring that water reaches households in a drinkable condition is of vital importance. However, ageing urban infrastructure, neglected and rusty water tanks in blocks of flats, and ageing plumbing pipes are adversely affecting the taste, odour and chemical composition of the water.

Chlorine, Limescale and Hidden Dangers in Water

Tap water is heavily chlorinated to protect it from bacteria and viruses throughout its journey through the distribution network. Although chlorine is an essential substance for disinfection, by the time the water reaches the end user, it not only creates an unpleasant taste and odour but is also a chemical compound that is not recommended for long-term consumption. Furthermore, heavy metals such as lead, mercury, asbestos and iron, which leach from old pipework, pose major, yet invisible, hazards. Furthermore, pesticide residues that enter the water and high levels of limescale (calcium carbonate) are among the primary factors directly reducing the quality of tap water.

What Exactly Do Water Purifiers Do?

When the benefits of water purification systems are examined, it becomes clear that these systems remove not only coarse impurities from the water but also harmful components at the molecular level. An advanced domestic water purification system typically consists of five or more stages. The water first passes through sediment filters to remove sludge, rust and sand. Next, activated carbon filters come into play, removing chlorine, unpleasant odours and organic chemicals from the water. However, the technology that truly sets water purification systems apart is the membrane system at the heart of the process, which purifies the water to 99 per cent purity.

What is Reverse Osmosis Technology?

Understanding what reverse osmosis is is essential to grasping the need for such a device. The RO (Reverse Osmosis) system, used in the best water purification systems, passes water through a semi-permeable membrane filter with pores measuring one millionth of a millimetre (0.0001 microns). This technology is so precise that heavy metals, chemicals, microplastics and viruses are unable to pass through these pores and are flushed out via the waste water outlet. What remains is drinking water in its purest, cleanest form. Reverse osmosis is the world’s most advanced and reliable filtration technology, used even on space stations to make waste water drinkable again.

Bottled Water or a Water Purifier? (A Comparison)

Rising costs and hygiene concerns have prompted consumers to seek alternatives. Whilst the trend towards domestic water purification systems is growing rapidly, approximately 30 per cent of households (over 7 million households) already have a purification system. According to data from the Association of Bottled Water Producers (SUDER), the 9.5 per cent decline in the consumption of bottled water clearly demonstrates that people are moving away from this method, driven both by economic reasons and by growing awareness of the harm caused by plastic bottles.

The Dangers of Plastic: BPA and Microplastics

The greatest risk associated with bottled water arises during the logistics and storage stages. Polycarbonate bottles are generally used for long periods of up to 3–4 years. Exposure of these containers to sunlight (UV rays) and excessive heat whilst in lorry lorries causes BPA (Bisphenol A), a chemical present in the plastic, to leach directly into the drinking water. The danger posed by BPA can lead to a wide range of problems, from hormonal imbalances to cellular damage. Furthermore, leaving water to stand in plastic for long periods creates conditions for microplastic particles to leach into the water. Failure to adequately sterilise jug pumps and bottles, meanwhile, accelerates bacterial growth.

Cost and Savings Analysis (ROI)

To understand the financial case for investing in a water purifier, it is sufficient to compare the annual expenditure on bottled water for an average family of four with the cost of purchasing a water purifier. Although the cost of a water purification system may appear at first glance to be a one-off expense, the system pays for itself within a short period of time.

Table: Comparison of Annual Costs for Bottled Water and Water Purifiers

According to this table, whilst a family of four spends 15,600 TL a year on bottled water, by making a one-off payment for a high-quality water purifier, they will recoup their investment (ROI) within an average of 6 to 10 months. In subsequent years, as the cost of replacing the filters in the water purification system is very low, the household will experience significant water savings and financial relief.

Health Myths: Is Treated Water Unhealthy?

The most common urban myth circulating in society regarding water purification systems is the perception that ‘they remove all the minerals from the water and therefore produce “dead water”’. This argument may only apply to older, industrial-type systems. In modern systems, this issue has been completely resolved through the use of filter technologies that are biologically compatible with human health.

World Health Organisation (WHO) Warning and the Solution Offered by Alkaline Filters

When we approach the subject from a scientific perspective, the report ‘Nutrients in Drinking Water’, published by the World Health Organisation (WHO), states that the regular consumption of demineralised water (pure water stripped of all its minerals) is not recommended. Reliable and high-quality water filtration brands have, based precisely on this scientific fact, added a vital sixth stage to their systems, known as an ‘Alkaline Filter’ or ‘Mineral Filter’. This filter restores natural calcium, magnesium and potassium minerals, derived from nature, to the water purified by the membrane. As a result, the water attains the form of healthy alkaline water with a pH value between 7.2 and 8.5.

Does Treated Water Cause Osteoporosis?

The claim that “treated water causes bone loss (osteoporosis)” is a completely baseless myth that contradicts scientific evidence. According to research by Harvard Medical School and nutrition experts, the human body obtains more than 90 per cent of its daily mineral requirements from food. Calcium and magnesium, which are essential for bone development, are absorbed by the body through milk, yoghurt, cheese, nuts and green leafy vegetables. The contribution of minerals in water to human nutrition is extremely small, and the mineral filter in modern appliances easily compensates for this minor shortfall, producing ideal drinking water.

In Which Situations Is a Water Purifier Absolutely Essential?

For some households and premises, a water purifier is not a choice but an absolute necessity. If you have a baby or young children at home, you must protect their developing immune systems from heavy metals and microplastics. Furthermore, if you live in an area where the TDS (Total Dissolved Solids) level of tap water is high, you can only remedy the hard, bitter taste of your water with a reverse osmosis system. It is strongly recommended that residents of buildings over 15–20 years old use a domestic water purification system to guard against the risk of rust and corrosion in the building’s internal plumbing.

Environmentally Friendly Water Consumption (Zero Plastic Waste)

According to global statistics, 1 million bottles of packaged water are consumed every minute worldwide, and only a very small proportion of this plastic can be recycled. An average family, by using water bottles, contributes to the production and transport of approximately 150–200 massive plastic containers each year. Exhaust emissions during the logistics process are another issue altogether. However, by using a single water filtration system, you can significantly reduce your family’s carbon footprint and take a step towards an eco-friendly lifestyle with the aim of producing zero plastic waste.

What Should You Look Out for When Buying a Water Purifier?

Choosing the right appliance is just as important for your health and your budget as buying the most basic model. Today, water purification technologies have evolved from the bulky systems that used to take up a huge amount of space under the sink to extremely stylish, compact designs. The key technology trends and features you should look out for are as follows: filters and components with NSF certification, recognised internationally, should be used; the unit should be fitted with a smart water leak sensor to detect any potential leaks; for homes with low water pressure, motorised models that minimise waste water should be selected; and, where possible, systems with digital displays that allow you to monitor filter life in real time should be preferred.

Clean water is not a luxury, but a basic necessity

When examined from the perspectives of both physical and biological health, as well as household and business finances, it is clear that the use of water purification systems in homes and workplaces is an extremely sensible, reliable and necessary investment. You need not be caught between the poor quality of tap water and the plastic-related risks and ever-increasing costs associated with bottled water.

Frequently Asked Questions (FAQ)

Do water purifiers actually work?

Yes, it certainly works. Devices utilising reverse osmosis technology remove chlorine, heavy metals (lead, mercury, arsenic), pesticide residues and viruses from tap water at a rate of up to 99 per cent. Whilst improving the smell and taste of the water, they reduce the TDS (Total Dissolved Solids) level to the World Health Organisation’s recommended range of 20–40 ppm for drinking water, thereby providing a healthy solution to the question ‘What is TDS?’

Why isn’t treated water good? (Is a water purifier harmful?)

The idea that purified water is harmful is a misconception relating to water produced by older-style industrial machines that do not add minerals. Modern domestic machines feature alkaline/mineral filters as the final stage. These filters restore beneficial minerals such as calcium, magnesium and potassium to the purified water, bringing the water’s pH balance to a healthy alkaline level (7.2–8.5).

Does treated water cause osteoporosis?

No, filtered water does not cause osteoporosis. The human body obtains more than 90 per cent of the minerals required for bone development from foods such as cheese, yoghurt and green leafy vegetables. The amount of minerals in water accounts for only a very small proportion of daily nutritional requirements, and new-generation mineral filters successfully compensate for this shortfall.

Is it healthy to drink unfiltered water? (Is filtered water healthy at home?)

Drinking water from a high-quality water purifier that undergoes regular maintenance and filter changes (usually every 6–12 months, depending on usage) is extremely healthy. What’s more, this method completely eliminates the risks of microplastics and chemical leaching that arise from plastic bottled water being left to stand for long periods.
