DIY Home Microplastics Filtration Guide

Every day, millions of concerned homeowners search for real answers to this growing threat: How do I remove microplastics from my drinking water? Yet, most answers online are either buried in hard-to-read research or lack practical, hands-on solutions. This blog changes that.

This comprehensive, step-by-step DIY guide reveals a reliable way to build your own home microplastic filtration system, using widely available parts, with deep insights into why it works—based on science and not just marketing claims.

What Are Microplastics?

Microplastics are plastic fragments less than 5 mm in size—some even smaller than 0.1 microns. They’re found in ocean water, bottled water, tap water, and even rain. Microplastics come from degraded plastic products, synthetic clothing fibers, cosmetic beads, and industrial waste.

Recent studies have found microplastics in human blood, lung tissue, and placenta. While the long-term effects on health are still under investigation, early signs point to potential disruption of hormonal systems, gut microbiome changes, inflammation, and more.

How Do Microplastics Enter Your Water?

• Municipal Supply: Tap water can contain fibers from synthetic fabrics and microbeads from personal care products.
• Plumbing Leaching: Plastic pipes degrade over time.
• Contaminated Sources: Lakes and rivers often receive industrial and residential plastic waste.

Filtration Science: What Works and Why

Filtration effectiveness is all about pore size. Microplastics span a wide size range. Here’s a comparison of available filtration technologies:

Filter Type	Micron Rating	Effectiveness Against Microplastics
Standard Pitcher Filter (e.g. Brita)	>1 µm	Poor
Sediment Filter	0.5 µm	Good for large particles
Ultrafiltration (UF)	0.01–0.1 µm	Excellent
Nanofiltration	0.001–0.01 µm	Excellent (also removes viruses)
Reverse Osmosis	<0.001 µm	Excellent but expensive & wasteful

For this DIY build, ultrafiltration offers the best balance between cost, ease of use, and effectiveness.

Step-by-Step DIY Filtration System

1. Start with a 0.5 µm Sediment Filter – This protects your finer membranes from clogging. Use a standard 10-inch filter housing with quick-connect ports.
2. Add an Ultrafiltration Membrane – Install a hollow fiber UF cartridge from Fresh Water Systems (0.01 µm).
3. Optional: Nano Carbon Filter – Use Aquablu’s nano-carbon for taste and toxin removal.
4. Use food-grade tubing to connect all filters. Secure with push-fit connectors.
5. Mount on a wall or under sink, or use a countertop frame. Flush the system thoroughly for 5 minutes before first use.

Materials List & Cost Breakdown

• 0.5 µm Sediment Filter Housing – $20
• Ultrafiltration Cartridge – $35
• Nano Carbon Filter (optional) – $25
• Food-Grade Tubing – $10
• Quick-connect Fittings – $5
• Wall Mount Brackets – $5

Total: $70–95. No electricity, no pump, no waste water.

Maintenance & Filter Replacement

• Sediment Filter: Replace every 6 months.
• UF Membrane: Replace annually or as needed.
• Carbon Filter: Replace every 4–6 months.

Frequently Asked Questions

Can I test my water for microplastics?

Currently, there are no consumer-grade tests, but labs like Eurofins offer testing for ~$150.

Does boiling or freezing water help?

Neither process removes microplastics. In fact, boiling can concentrate them.

Can I adapt this to a fridge or gravity-fed setup?

Yes! Use fridge-compatible quick fittings or install on a 5-gallon bucket for camping/off-grid use.

Conclusion

Filtering out microplastics is not just possible—it’s practical. With just a few components, you can take your family’s water safety into your own hands. Commercial systems with similar performance cost 5–10x more.
