With alarming headlines about the health impacts of microplastics in our bodies, homes and environments, what's the evidence and how can we reduce our exposure, especially concerning drinking water.
Microplastics In Water: Bottled Or Tap Water?
Studies show that bottled water often has higher microplastic concentrations than tap water. This is true for both plastic bottles (where fragments break down, especially when heated) and glass bottles (due to abrasion from plastic screwcap coatings). A recent study even found that while overall particle numbers were similar, the microplastics in bottled water were significantly smaller, which could be more concerning from a toxicity standpoint. It seems tap water is generally a better choice, and using a water filter can further help remove microplastics.
RO Water Filters Remove Microplastics
A good RO water filter can remove up to 95% of microplastics and contaminants, including bacteria, viruses, chlorine and lead from tap water. This makes the water safe and clean for drinking and other uses.
Reverse osmosis (RO) water purifiers are able to produce an amazing level of water purity and remove nearly all contaminants, delivering a highly pleasing, fresh tasting drinking water.

The Health Impact Of Microplastics
While there's strong evidence of environmental harm from microplastics (like disrupting the blue carbon cycle), their impact on human health is still emerging. However, lab studies suggest they can cause oxidative stress, cellular damage, and immune responses. Many scientists advocate for a precautionary approach, encouraging us to reduce our exposure where possible. The University of Portsmouth's Global Plastics Policy Centre believes a UK microplastics policy is urgently needed, drawing parallels to persistent contaminants like PFCs and "forever chemicals" where delayed action led to significant public health concerns.
Ways to Reduce Microplastics Exposure
Although completely avoiding microplastics is impossible, there are simple changes we can make individually to reduce exposure from sources known to release high levels:
1. Avoid heating plastic: Heat causes microplastics and additives to leach into food and drinks, even in "microwave-safe" plastics. It's best to heat food in glass or other containers and decant ready meals. Also, avoid leaving plastic bottles in the sun.
2. Consider loose-leaf tea: Many teabags contain plastic sealants, leading to a steady dose of microplastics when steeped.
3. Use reusable metal coffee cups: Disposable coffee cups often have plastic linings that can leach into hot drinks.
4. Don't freeze plastic: Freezing can make plastic brittle, increasing particle shedding. Pyrex is a good alternative.
5. Switch to stainless steel pans and non-plastic utensils: Non-stick pans contain plastic coatings and PFAS, and worn plastic utensils can shed particles.
6. Be mindful of processed and farmed foods: Microplastic levels are thought to be higher in processed foods due to potential contamination during packaging. Farmed fish can also have higher levels than wild fish, partly due to plastic pipes and pellets used in their feed.
7. Avoid plastic chopping boards: Tiny pieces of plastic can chip off into food.
