Stages of filtration

1. Coarse filtration (Aqualite PS20, 20 µm): removes sand, rust, silt, and other large particles.
2. Chlorine removal (Aqualite CTO10): compressed activated carbon eliminates chlorine and organochlorine compounds, protecting the membrane.
3. Fine filtration (Aqualite PS5, 5 µm): captures smaller mechanical impurities.
4. Reverse osmosis (50 GPD membrane): removes up to 99.8% of dissolved solids, bacteria, viruses, hardness salts, and heavy metals.
5. Post-filter (Aqualite Post QC): improves taste and odor of water after the tank.

Maintenance and replacement schedule

• PS20 cartridge (20 µm): every 3 months
• CTO10 cartridge (carbon): every 3–6 months
• PS5 cartridge (5 µm): every 3–6 months
• 50 GPD membrane: every 18–24 months
• Post-filter Post QC: every 6–12 months

The poorer the source water quality, the more often cartridges need to be replaced. With cloudy or heavily chlorinated water, replacement may be required every 2–3 months.
