FAQ:

How often should I replace filters and membranes?

Filter and membrane lifespan depends on water quality, usage, and system type. General guidelines:
1. Sediment & Carbon Filters: Replace every 6–12 months.
2. RO Membranes: Replace every 2–3 years, depending on water conditions.
3. UF/NF Membranes: Replace every 1–2 years.
Regular maintenance ensures optimal performance and water quality.

Which chemicals are required for regeneration?

Softening uses NaCl. Demineralization uses HCl or H₂SO₄ for cation resin and NaOH for anion resin.

Are mixed bed systems better than two-bed systems?

Mixed bed polishers are used for final polishing after RO or two-bed deionization to achieve ultra-pure water.

How do I know when to add salt to my softener?

Check the brine tank monthly. Modern systems often alert you automatically when salt levels are low.
