How to Choose the Right Irrigation Filter
Know Your Water Source
Each water source contains different types of impurities. Choosing the right filter is critical for system longevity.
| Water Source | Common Impurities | Recommended Filter Type |
|---|---|---|
| Borewell / Tube well | Sand, silt, small particles | Screen Filter |
| Canal / River | Algae, leaves, organic matter | Disc Filter |
| Pond / Tank | Sand + organic matter | Sand Filter + Disc Filter (Combination) |
| Municipal / Tap Water | Minor dust or particles | Screen Filter |
Check the Water Quality
- ● If water has sand or fine soil → Use Screen Filter
- ● If water has algae or organic matter → Use Disc Filter
- ● If water is muddy or mixed with debris → Use Sand + Disc Filter
Match the Filter to Your Irrigation Type
| Irrigation Type | Suitable Filter |
|---|---|
| Drip Irrigation | Disc Filter / Screen Filter |
| Sprinkler System | Screen Filter / Disc Filter |
| Large Area / Farm | Sand Filter + Disc Filter |
| Greenhouse / Nursery | Disc Filter / Screen Filter |
Consider Flow Rate and Micron Rating
💧 Choose a filter that matches your system's flow rate (m³/hr).
🌿 Micron rating decides how fine the filtration is:
- ○ 100–150 Micron → Ideal for drip irrigation
- ○ 200 Micron → Ideal for sprinklers
- ○ Below 100 Micron → For very fine filtration
Go for Easy Maintenance
Always choose a filter that is easy to clean and maintain:
● Screen Filter
Easy to remove and wash manually
● Disc Filter
Can be cleaned or backwashed easily
● Sand Filter
Requires regular backwashing for best performance
