How to Remove Microplastics from Tap Water
Microplastics, plastic fragments smaller than 5 mm, are present in rivers, seas and, in some cases, even in the water we drink. Although scientific evidence on their effects on human health is still evolving, reducing exposure is a sensible precaution.
This practical guide explains how to remove or reduce microplastics from tap water using household-friendly solutions, from block activated carbon filtration to reverse osmosis, as well as a simple boil-and-filter method.
Advanced Filtration Methods to Remove Microplastics at Home
Below we review the most common systems used in households. The right choice depends on the level of reduction you are looking for, your budget, the maintenance you are willing to carry out, and your sustainability preferences.
Block Activated Carbon Filtration
Block activated carbon filters adsorb and trap contaminants thanks to their extremely porous surface area. In addition, the block acts as a physical barrier against unwanted particles. In practice, this translates into better taste and odour (through chlorine and by-product reduction), as well as a decrease in microplastics and other common tap-water compounds.
Key Advantages
- Quick installation on the tap and easy maintenance (periodic cartridge replacement).
- Excellent cost-benefit ratio for daily use.
- Sustainable alternative to bottled water consumption.
Recommended Tappwater Solutions
- EcoPro Tap Filter – reduces chlorine, improves taste and helps lower the presence of microplastics for convenient daily use.
- EcoPro Compact Tap Filter – the same benefits in a smaller format, ideal for kitchens with limited space.
Tip: Replace the cartridge as often as recommended to maintain optimal filtration performance.
Reverse Osmosis: The Highest Removal Rate
Reverse osmosis (RO) uses a semi-permeable membrane with ultra-fine pores that retain very small particles, including microplastics. It typically offers the highest rejection rate against multiple contaminants.
Pros
- High reduction efficiency across a wide range of particles.
Cons
- Higher initial and maintenance costs.
- Can waste water during the rejection process.
- May remove beneficial minerals; remineralisation is sometimes recommended.
Recommendation: Consider RO if you are looking for maximum reduction and are comfortable with its cost, maintenance, and water use.
Ceramic or Granular Filters
Microporous ceramic or granular-media filters (such as certain carbons or specific materials) act as physical sieves. Their effectiveness against microplastics depends on the pore size and cartridge design. They can be a viable option, although it is always best to check the manufacturer’s specifications.
The Most Practical and Affordable Method: Boiling Water
In hard-water areas, boiling encourages the precipitation of calcium carbonate (limescale). These precipitates can trap suspended particles, which are then retained in a subsequent filtration step.
How to Apply This at Home
- Boil tap water.
- Let it stand to allow limescale to settle.
- Filter the water (for example, using a block activated carbon tap filter).
Limitations
- Less practical for large volumes.
- Does not on its own remove other dissolved contaminants (such as chlorine); hence the suggested filtration step.
Are Microplastics Dangerous?
Research is ongoing. Microplastics have been identified in various environments and in human biological samples, but their specific long-term effects are still under study. Taking steps to reduce exposure — especially in daily drinking water — is a prudent approach while science continues to progress.
How to Reduce Your Overall Exposure to Microplastics
Avoid Bottled Water Where Possible
Replace bottled water with filtered tap water. In addition to potential cost savings, you reduce single-use plastic consumption.
Use Reusable Containers
Choose stainless steel or glass bottles for carrying water. If you need to filter on the go, consider a filtered bottle.
Avoid Heating Plastics
Do not heat plastic containers in the microwave or pour very hot drinks into them unless they are designed for high temperatures.
Reduce Microfibres from Clothing
Wash on shorter, cold cycles whenever possible, and choose natural fibres to minimise the release of synthetic microfibres.
Conclusion: The Best Everyday Option
If you are looking for an effective, practical and sustainable way to reduce microplastics while improving the taste of your water, block activated carbon tap filters offer the best balance between performance and convenience.
