Quick Answer
A water filter during pregnancy is not mandatory, but it is advisable if you have old pipes, concerns about PFAS, or if you want maximum peace of mind. Dutch tap water meets strict standards but may contain traces of lead, microplastics, and drug residues. A certified inline water filter removes these substances and, through Swedish Mineral Rock, also adds calcium and magnesium, minerals that are especially important during pregnancy.

What is a water filter for pregnant women?
A water filter for use during pregnancy is a certified filtration system installed under the sink that purifies unfiltered tap water before you drink it. It filters out harmful substances such as lead, PFAS, microplastics, and drug residues, without removing beneficial minerals, or, in models with remineralization, it adds extra calcium and magnesium to the water.
Is tap water safe during pregnancy?
In the Netherlands, tap water is of high quality. Drinking water companies test the water for more than 60 parameters and must comply with the strict standards of the Drinking Water Act. According to the RIVM, Dutch drinking water is safe for almost everyone to drink, including pregnant women.
However, there are situations where extra caution is advisable. Research by Vewin, the umbrella organization for drinking water companies, shows that water quality at the tap in homes can differ from the quality at the source. Factors such as lead pipes, stagnant water, and local contamination play a role. During pregnancy, when the fetus is particularly vulnerable, taking an extra step can be beneficial.
The main concerns are lead in homes built before 1960, PFAS in certain regions, and microplastics, for which the RIVM states that the effects on fetal development are still being investigated. A water filter offers a practical and affordable solution in all these cases.
Which substances in tap water require extra attention during pregnancy?
Lead
Homes built before 1960 may contain lead pipes. Lead dissolves in stagnant water and can reach the fetus via the placenta. The GGD explicitly advises pregnant women to let the tap run for at least 2 minutes every morning if lead pipes are present. A water filter with NSF 53 certification demonstrably filters out lead.
PFAS (per- and polyfluoroalkyl substances)
PFAS, also known as "forever chemicals," are industrial compounds that do not break down in the environment or the human body. The RIVM follows WHO guidelines and advises limiting total PFAS intake through food and water. Pregnant women near industrial areas or airports are relatively more exposed to elevated PFAS concentrations. Our water filter for PFAS offers targeted protection.
Microplastics
Microplastics are now found in tap water, air, and food. Studies show that microplastics have also been found in placental tissue, although the long-term health effects are still unclear. The RIVM monitors the situation and advises applying the precautionary principle. A good filter retains particles smaller than 0.001 millimeters.
Drug residues and hormones
Residues of birth control pills, antidepressants, and antibiotics are found in very low concentrations in tap water. Milieu Centraal identifies this as a concern, although the measured values are well below the standards. For pregnant women who want to avoid unnecessary exposure, filtration is a logical choice.
Chlorine
Chlorine is used to disinfect tap water and is safe within legal limits. However, at increased dosages, for example during maintenance on the pipe network, the smell and taste can be unpleasant. An activated carbon filter completely removes chlorine. More information can be found on our page about chlorine and water filters.
Benefits of a water filter during pregnancy
A water filter during pregnancy not only offers protection but also a practical advantage: you drink more and more easily the required 2 to 3 liters per day when the water tastes better. PureFilter customer feedback shows that users drink on average 30 to 40% more water after installation than before, simply because the taste improves.

At PureFilter, we see that pregnant customers and young families most often choose the PureFilter Mineral+. The combination of purification and mineral addition makes it the most complete solution for them, without compromising on convenience or budget.
Minerals during pregnancy: why calcium and magnesium are extra important
What competing water filters often do not offer is the addition of minerals. The PureFilter Mineral+ works with Swedish Mineral Rock, a natural mineral rock that releases calcium, magnesium, and potassium into the water. This is particularly valuable during pregnancy.
Calcium
Calcium is essential for the fetal bone development. Pregnant women have an increased calcium requirement of approximately 1000 milligrams per day, according to the Voedingscentrum. Drinking water can be a valuable supplement to daily calcium intake through food.
Magnesium
Magnesium supports muscle relaxation and the nervous system. A magnesium deficiency during pregnancy is linked to an increased risk of cramps and fatigue. Filtered water with a mild but consistent magnesium content contributes to daily intake.
Potassium
Potassium plays a role in blood pressure regulation, which is especially relevant during pregnancy. The Swedish Mineral Rock filter naturally releases potassium, without the need for supplements or special mineral water.

Is a water filter necessary if I am pregnant?
It is not necessary: Dutch tap water is officially safe. But a water filter is advisable if you live in a home built before 1960, in an area with elevated PFAS concentrations, or simply want maximum peace of mind during your pregnancy. The costs do not outweigh the preventive value for fetal development.
Which water filter is best for pregnant women?
A certified inline filter with NSF 42, 53, 61, and 372 certification offers the best combination of purification, mineral preservation, and ease of use. The PureFilter Mineral+ meets all these requirements and also adds calcium, magnesium, and potassium via Swedish Mineral Rock, a unique feature that RO systems and water pitchers do not offer.
Can I use tap water to make baby food during pregnancy?
Yes, but always use cold tap water that you heat yourself. Hot water from the tap extracts more metals from pipes and has a higher risk of bacteria. After birth, the same advice applies to preparing formula. More information can be found in our blog about water filter for baby food.
Does a water filter also remove PFAS from tap water?
Yes, provided the filter is certified for PFAS removal. The PureFilter Mineral+ is NSF 53 certified and demonstrably removes PFAS compounds. Reverse osmosis is even more effective but requires professional installation and costs 300 to 800 euros. For most households, the PureFilter offers comparable protection for a fraction of that cost.
How long does a water filter last for a pregnant woman who drinks a lot?
The PureFilter Mineral+ has a capacity of 15,000 to 20,000 litres. With a daily use of 3 litres, the filter cartridge lasts over 13 years based on volume, but the recommended replacement frequency is annually for optimal performance. A replacement filter costs from 49.90 euros. View the replacement filter offer for current prices.
Can I install the PureFilter in a rental property?
Yes. The PureFilter Mineral+ connects as an inline filter to the existing cold water line under the sink, without drilling, gluing or permanent modifications. Installation takes 5 to 10 minutes and you can take the filter with you when you move. This makes it an ideal solution for rental properties. Also view our installation guide for under-sink water filters.
Conclusion: water filter during pregnancy
Dutch tap water is safe, but no water is perfect. Especially during pregnancy, when the foetus is more vulnerable to exposure to lead, PFAS, microplastics and medicine residues, a certified water filter is a smart investment in peace of mind and health.
What distinguishes PureFilter from alternatives is not only the purification of more than 100 contaminants, but also the addition of calcium, magnesium and potassium via Swedish Mineral Rock. Minerals that your body and that of your baby need extra during pregnancy. Combined with an installation of 5 to 10 minutes, a price of 149.90 euros and NSF certification at four levels, it is one of the most complete water filters for use during pregnancy.
