How to choose the right water filter in BD (step-by-step)
Test your water (TDS + basics): Get a simple TDS meter (inexpensive) and note the ppm. Observe color, smell, and taste. If you suspect iron/arsenic/coliforms, consider a lab test many local labs offer affordable packages.
Map result technology: TDS < 300–400 ppm & municipal, UV/UF + Carbon (no RO). TDS > 500–600 ppm or salty taste- RO + Carbon (add UV/UF if microbial risk). Iron/arsenic zones- Pre-treatment + RO with certified media.
Check service & spares: In Bangladesh, after-sales service is king. Pick brands with authorized service centers in your district and readily available filter kits.
Calculate real yearly cost: Ask for AMC (Annual Maintenance Contract) or filter bundle price. Typical annual change- sediment + carbon + UF; RO membrane lasts longer (often 18–36 months) depending on water quality.
Consider water wastage & recovery (for RO): Traditional RO can waste 2–3 L per 1 L of pure water. Look for low-waste membranes, recovery-enhanced pumps, and reuse the rejected water for floor cleaning or gardening.
Size & storage: A family of 4–6 usually needs 7–10 L storage. For offices/shops, consider high-flow or commercial RO (50–100 GPD+).
Taste preference: If RO tastes “too flat,” choose models with TDS controller/mineralizer to restore natural taste.
Safety & quality tips for BD buyers

Ask for installation checklist: inlet pressure, TDS reading before/after, leak test, waste-water ratio.
