🔷 25kg EGFM Eco Glass Filter Media Grade 1 (G1) – 0.5mm to 1mm
🔷 Transform Your Pool Filtration with 30% Better Clarity Using Eco-Friendly Recycled Glass Technology
📋 Product Overview
EGFM (Eco Glass Filter Media) Grade 1 is an environmentally friendly filter media manufactured from 100% recycled UK glass, providing a superior and sustainable alternative to traditional silica sand. This premium filtration media delivers exceptional water clarity through its unique angular to sub-angular particle shape, which captures up to 30% more contaminants than conventional sand filters.
Grade 1 represents the finest filtration grade in the EGFM range, with a precise particle size of 0.5mm to 1mm, making it ideal for capturing the smallest debris particles and achieving crystal-clear pool water. Unlike traditional sand which degrades over time, EGFM’s glass composition maintains its filtration efficiency throughout its extended lifespan.
Designed for both residential pool owners and commercial aquatic facilities, EGFM Grade 1 is compatible with all standard filter systems featuring laterals or nozzle plates. Its non-porous composition resists bacterial colonisation, creating a healthier filtration environment whilst reducing your chemical treatment requirements.
⭐ Key Features
✅ 30% Improved Turbidity Removal – Angular particle shape captures significantly more contaminants than equivalent grade silica sand, delivering noticeably clearer water
✅ 50% Reduced Backwash Water Usage – Superior permeability allows faster, more efficient backwashing, cutting your water and energy costs substantially
✅ 15% Less Media Required – Lower density than sand means you need less product to fill your filter, offering immediate savings
✅ Filtration Down to 5 Microns – Captures particles invisible to the naked eye, removing debris that standard sand filters miss entirely
✅ Bio-Fouling Resistant – Smooth, non-porous glass surface prevents bacteria from becoming trapped in cracks or flaws, unlike porous silica sand
✅ Extended Lifespan – Glass media doesn’t degrade like sand, maintaining filtration performance year after year (recommended replacement every 5 years)
✅ Reduced Chemical Usage – Cleaner filtration means less remedial chemical treatment required to maintain water quality
✅ Eco-Friendly Credentials – Made from recycled UK glass, eliminating the need for environmentally damaging sand mining operations
✅ Safe to Handle – All grades are milled to remove sharp points, ensuring safe and easy installation

📊 Grade Selection Guide
🎯 EGFM is available in three grades, each designed for specific filtration requirements. Understanding which grade to use ensures optimal filter performance.
| Grade | Grain Size | Sand Equivalent | Recommended Use |
|---|---|---|---|
| Grade 1 (G1) | 0.5mm – 1.0mm | 16/30 Grade Sand | Fine filtration layer / Top of filter bed |
| Grade 2 (G2) | 1.0mm – 3.0mm | 8/16 Grade Sand | Medium filtration / Middle layer |
| Grade 3 (G3) | 3.0mm – 6.0mm | 6mm Gravel | Support layer / Bottom of filter bed |
Multi-Grade Filter Configuration
For smaller filters (up to 760mm / 30″ diameter):
- Use a 50/50 mix of Grade 1 and Grade 2
For larger filters (above 760mm / 30″ diameter):
- 50% Grade 1 (top layer – fine filtration)
- 25% Grade 2 (middle layer)
- 25% Grade 3 (bottom layer – support)
⚠️ Important: Always add the larger grade first at the bottom of the filter, working up to the finest grade on top.
📐 Quantity Guide
🧮 EGFM is 85% of the density of silica sand. If you know your current sand weight, simply multiply by 0.85 to calculate the EGFM required.
Quick Calculation: Sand Weight (kg) × 0.85 = EGFM Required (kg)

💎 Performance Benefits
Superior Filtration Efficiency
EGFM’s angular to sub-angular particle shape provides a 30% improvement in turbidity removal compared to silica sand. The media captures particles down to 5 microns, removing contaminants that conventional sand filters simply cannot trap, resulting in visibly clearer pool water.
Reduced Water Consumption
With superior permeability compared to traditional sand, EGFM backwashes more efficiently, using up to 50% less water. This translates directly to lower water bills, reduced heating costs for replacement water, and less chemical treatment required.
Extended Media Lifespan
Unlike silica sand which degrades and compacts over time, glass media maintains its structure and filtration efficiency throughout its service life. While sand typically requires replacement every 3-5 years, EGFM’s durability means it can last significantly longer, with a recommended replacement interval of 5 years.
Healthier Filtration Environment
Traditional sand filters are known to harbour bacteria, including potentially harmful varieties such as Legionella. EGFM’s smooth, non-porous glass surface discourages bacterial attachment, creating a healthier filter tank and reducing the need for remedial chemical treatments.
Chemical Cost Savings
Cleaner filtration means less work for your sanitisers. Pool owners consistently report reduced chlorine consumption and fewer algaecide treatments when using glass filter media.
🎯 Real World Applications
🏊♂️ Residential Swimming Pools
Perfect for homeowners seeking the clearest possible pool water with reduced maintenance. Grade 1’s fine filtration captures body oils, sunscreen residue, and microscopic debris that sand filters miss.
🛁 Hot Tubs & Spas
Ideal for spa filtration where water clarity and hygiene are paramount. The bio-resistant properties help maintain a cleaner, healthier soaking environment with reduced chemical intervention.
🏢 Commercial Pools & Leisure Centres
Meeting the demanding filtration requirements of high-bather-load environments. EGFM helps commercial operators maintain water quality standards whilst reducing operational costs.
🌿 Ponds & Water Features
Effective for ornamental water features where clarity is essential. The non-toxic, eco-friendly composition is safe for aquatic environments.
🏭 Aquaculture & Water Treatment
Suitable for professional water treatment applications where reliable, consistent filtration performance is required.
🔄 Installation Notes
🛠️ Converting from sand to EGFM is straightforward and follows similar procedures to standard media replacement.
Before Installation
- Switch off your pump and filtration system
- Drain the filter tank completely
- Remove all existing sand or filter media
- Clean the filter tank interior and inspect laterals/nozzle plates for damage
- Check the central standpipe is properly sealed
Media Installation
- Cover the standpipe opening to prevent media entering the pipe
- Add a small amount of water to the tank (cushions the media during filling)
- For multi-grade filters: Add Grade 3 first (bottom layer), then Grade 2 (if used), then Grade 1 (top layer)
- For single-grade filters: Add Grade 1 throughout
- Level the media surface and remove the standpipe cover
After Installation
- Reconnect the multiport valve
- Set valve to BACKWASH position
- Run pump for 2-3 minutes to flush out fine particles
- Switch to RINSE for 1 minute
- Return to FILTER mode – your system is ready to use
