Our approach: we do not name brands or take money from manufacturers. Each card tells you what to look for so you can judge any product yourself.
Water filters
Reverse osmosis system (under-sink or countertop)
- Why
- Removes nearly all microplastics and much of the nanoplastic range, plus many other contaminants.
- Look for
- NSF/ANSI 58 (RO performance), ideally also 401 with a microplastics claim. A glass or steel water reservoir on countertop units.
- Trade-offs
- Higher cost, some wastewater, removes minerals. Under-sink units need installation.
Certified pitcher, faucet or under-sink carbon filter
- Why
- A cheaper option that removes most microplastic particles in the tested size range.
- Look for
- "Microplastics reduction" under NSF/ANSI 401 in the official listing for the exact cartridge model. Solid carbon block, not loose granules.
- Skip
- Packaging that says "reduces microplastics" with no certification body named.
Drinkware
Stainless steel or glass water bottle
- Why
- Replaces single-use plastic bottles, which shed more when squeezed, reused or warmed.
- Look for
- Food-grade 18/8 (304) stainless steel, or borosilicate glass with a protective sleeve. Unlined interior.
- Note
- Most lids contain plastic. Keep hot drinks below the lid line.
Ceramic or steel travel mug
- Why
- Avoids plastic-lined paper cups and plastic lids for hot coffee and tea.
- Look for
- Steel or ceramic interior. Lids with minimal plastic contact, or a sip-through steel lid.
Food storage and reheating
Glass containers
- Why
- Safe to microwave and oven-heat without shedding plastic. The single most useful kitchen purchase.
- Look for
- Borosilicate or tempered glass rated for oven and microwave. Remove the plastic lid before heating.
Stainless steel lunch boxes and containers
- Why
- Light and unbreakable for lunches, kids and travel.
- Look for
- 18/8 stainless steel. Silicone seals rather than plastic where possible. Not for microwaves.
Beeswax or plant-wax wraps
- Why
- Replace cling film for cold foods, bread, cheese and produce.
- Note
- Not for raw meat or hot food.
Cookware, utensils and prep
Stainless steel or glass kettle
- Why
- Polypropylene kettles shed particles at levels similar to baby bottles when boiling water.
- Look for
- A fully steel or glass interior, with no plastic in contact with the water (check the lid and water window).
Stainless steel, cast iron, carbon steel or enameled pans
- Why
- No coating to scratch off, unlike PTFE nonstick pans.
- Note
- If you keep nonstick, use wooden utensils and replace pans with visible scratches.
Hardwood or bamboo cutting board
- Why
- Plastic boards can add tens of millions of particles a year to food.
- Look for
- End-grain or edge-grain maple, walnut or cherry, or solid bamboo. Oil it monthly.
Wooden and steel utensils
- Why
- Nylon spatulas and spoons wear down in hot pans.
- Look for
- Solid wood, stainless steel, or food-grade silicone heads on steel handles.
Tea and coffee
Loose-leaf infuser or teapot
- Why
- Plastic tea bags can release billions of particles per cup.
- Look for
- Stainless steel mesh or ceramic infuser. If you prefer bags, choose ones labeled plastic-free.
French press, pour-over or steel moka pot
- Why
- Keeps hot water away from plastic pods and plastic machine parts.
- Look for
- Glass or steel body, steel filter or unbleached paper filters.
Baby feeding
Glass baby bottles
- Why
- Polypropylene bottles released millions of particles per liter during standard formula prep.
- Look for
- Borosilicate glass with a silicone sleeve. Stainless steel bottles are another option.
- Also
- A glass or steel jug for mixing formula if you keep plastic bottles. See safer formula prep.
Laundry
External washing machine filter
- Why
- Captures up to about 90% of microfibers in tests, the most effective laundry option.
- Look for
- Fine mesh (around 100 µm or smaller) that fits your drain hose, with an easy-to-empty cartridge. Put caught fibers in the trash, not the drain.
Filter wash bag or fiber-catching ball
- Why
- Cheaper, no installation. Catches fewer fibers than an external filter but reduces shedding from synthetics.
- Use for
- Fleece, activewear and other synthetic garments.
Home air and dust
HEPA vacuum cleaner
- Why
- Captures fine fibers and particles instead of blowing them back into the air.
- Look for
- A sealed system with a true HEPA filter (not "HEPA-type"). Bagged models release less dust when emptied.
HEPA air purifier
- Why
- Reduces airborne fibers and dust, most useful in bedrooms.
- Look for
- True HEPA filter and a clean air delivery rate (CADR) matched to your room size.
Natural-fiber bedding, rugs and clothing
- Why
- Cotton, linen, wool and hemp shed natural fibers, not plastic.
- Look for
- 100% natural fiber on the label. Blends still contain synthetics.
Personal care
Microplastic-free cosmetics, plastic-free wipes and floss
- Why
- Removes intentionally added plastic polymers, especially from lip and mouth products.
- Look for
- Ingredient lists without polyethylene, nylon-12, PMMA or acrylates copolymer. Silk or plant-fiber floss. Wipes made of 100% plant fibers. See ingredient names.
Products to be skeptical of
- Supplements, teas or cleanses claiming to flush microplastics from your body.
- "Microplastic-free" labels with no test method or certifier named.
- "Biodegradable" plastic food containers used for hot food. Many only break down in industrial composting.
- Bamboo-melamine dishes, which can release melamine and formaldehyde when heated.
- Home water test strips for microplastics, which cannot measure them reliably.
Frequently asked questions
What is the best water filter for microplastics?
A reverse osmosis system removes the most particles, including much of the nanoplastic range. For a pitcher or faucet filter, choose a model whose listing in the NSF, IAPMO or WQA database shows a microplastics reduction claim under NSF/ANSI 401.
Is stainless steel better than plastic for water bottles?
Yes, for microplastics. Food-grade stainless steel (often labeled 18/8 or 304) does not shed plastic particles. Note that most lids still contain plastic, so avoid filling with very hot drinks up to the lid.
Are silicone products plastic-free?
Silicone is a different material from conventional plastics and is more heat-stable. It is a reasonable choice for lids, bottle nipples and baking mats, but little research exists on particle release from silicone, so glass and steel remain the first choice for heating.
Why doesn't this guide name brands?
Certifications and materials stay accurate longer than product lineups, and we do not take payment from manufacturers. Use the criteria here to judge any brand, and verify filter certifications in the official databases.
