The 5 Stages of Filtration Explained

The APEC ROES-50 employs a meticulously designed five-stage filtration process to strip water of nearly all impurities:

1. High-Capacity Sediment Filter (10 inches, 5 microns): This initial stage acts as the first line of defense, removing larger particles such as dirt, rust, sand, and other sediments. This protects subsequent filters from premature clogging.
2. Activated Carbon Block Filter (10 inches, premium quality): Made from compressed activated carbon, this filter efficiently removes chlorine, tastes, odors, cloudiness, and volatile organic chemicals (VOCs) that can affect water quality.
3. Activated Carbon Block Filter (10 inches, premium quality): A second carbon block filter provides enhanced removal of remaining chlorine and organic compounds, ensuring thorough pre-treatment before the RO membrane.
4. High Rejection Reverse Osmosis Membrane (50 GPD): This is the heart of the system. The RO membrane features microscopic pores that allow only water molecules to pass through, effectively rejecting up to 99% of TDS, including fluoride, lead, arsenic, nitrates, heavy metals, and numerous other contaminants.
5. Advanced Coconut Shell Refining Carbon Filter: As the final stage, this post-carbon filter further polishes the water, removing any lingering tastes or odors from the storage tank, delivering a crisp, refreshing taste.
