How Reverse Osmosis Water Filters Produce Pure and Healthy Water
Water filters play a crucial role in improving water quality and removing harmful contaminants. Reverse osmosis (RO) filters are among the most effective types of water filters, capable of removing up to 99% of impurities. This article delves into the process of RO filtration and highlights the benefits of using Brafco water filters for pure and healthy water.

The Three Initial Stages of Filtration
The first three stages of RO filtration focus on removing suspended particles and preparing the water for the advanced RO membrane:
Stage 1: Pre-Filter
The pre-filter traps large impurities such as sand, dirt, and rust, protecting the subsequent stages from clogging. It typically consists of a multi-layered, high-quality compressed cotton material that minimizes blockages and pressure loss.
Stage 2: Granular Activated Carbon (GAC) Filter
The GAC filter targets smaller contaminants like chlorine, organic chemicals, and residual sediments from the pre-filter. It utilizes high-grade coconut shell carbon and small-pore carbon particles (1.5 mm) to maximize filtration efficiency and filter lifespan.
Stage 3: Carbon Block (CTO) Filter
The CTO filter effectively removes remaining chemicals, chlorine, odors, and tastes from the water. It consists of solid carbon granules that further refine the water quality.
Stage 4: Reverse Osmosis (RO)
The RO stage represents the heart of the filtration process, employing a semipermeable membrane to separate pure water from impurities:
The Principle of Reverse Osmosis:
RO mimics the natural phenomenon of osmosis, where water molecules move from a less concentrated solution (low solute concentration) to a more concentrated solution (high solute concentration) through a semipermeable membrane. In RO filtration, high pressure is applied to the concentrated solution (impure water), forcing water molecules to pass through the membrane, leaving behind dissolved salts, minerals, and contaminants.
Advantages of Reverse Osmosis:
RO filtration offers several notable advantages:
When to Change Water Filters
The frequency of filter replacement depends on the filter type, size, and usage. Generally, water filters should be replaced every 6 to 12 months, following the manufacturer's instructions. However, if you use a significant amount of water or live in an area with high levels of contaminants, you may need to change them more frequently.
Brafco Water Filter Replacement Guidelines for Pure and Healthy Water:
To maintain water quality, extend the lifespan of your RO system, and protect the pump and membranes, Brafco recommends the following filter replacement schedule:
- Stages 1-3: Every 6 months or approximately 10,000 liters of usage.
- Stage 4 (Membranes): Every 2 years.
- Additional Stages: Every 8-12 months.
Signs Indicating Filter Replacement or RO System Maintenance:
- Changes in Water Color, Odor, or Taste: Noticeable variations in water appearance or flavor may indicate filter saturation.
- Reduced Water Flow: A decrease in water flow suggests filter clogging and the need for replacement.
- Visible Sediment or Contaminants in Water: If you observe particles in your water, it's time to change the filters.
- Significant Color Change in Filters: Darkened or heavily soiled filters indicate excessive buildup and require replacement.
