BasideWT- Whole Home Water Filtration System & Replacement
20 inch Water Filter Cartridges | BasideWT
PRODUCT PARAMETERS
Product Overview / Description
The BasideWT 20 inch Water Filter Cartridges are high-capacity filtration components engineered for RO systems, softening systems, and whole-house filtration setups. They effectively remove sediments, chlorine, and organic compounds, providing clear and safe water for drinking and industrial processes.
These cartridges feature multi-layer polypropylene construction, ensuring both structural integrity and high dirt-holding capacity. Whether used in a commercial water treatment plant or a home reverse osmosis system, they maintain consistent flow rates and filtration efficiency.
Key Features and Benefits
- High Filtration Efficiency: Each 20 inch filter cartridge traps fine particles, rust, and sediments, ensuring superior water clarity.
- Durable Construction: Made from FDA-grade polypropylene for strength, chemical resistance, and safety.
- Universal Fit: Compatible with most standard 20-inch filter housings for easy installation and replacement.
- Extended Lifespan: Long-lasting performance reduces replacement frequency, saving maintenance costs.
- Multi-Stage Compatibility: Ideal for pre-filtration in RO systems, carbon filters, and softener setups.
- Stable Pressure Resistance: Designed to handle continuous flow without collapsing or clogging.
Interestingly, although many filters claim high efficiency, BasideWT’s 20 inch Water Filter Cartridges maintain stable performance even under variable water pressure—something cheaper models often fail to achieve.
Understanding the Function of 20 Inch Water Filter Cartridges
What Does a Filter Cartridge Actually Do?
A filter cartridge is the core of any purification system. It removes impurities such as sediment, rust, chlorine, organic matter, and microorganisms. The 20 inch water filter cartridges provide a larger filtration surface and higher flow rate than shorter cartridges.
Each layer of the cartridge performs a specific task. The outer layer traps large particles, while the inner core removes finer contaminants. The result? Clearer, better-tasting, and safer water.
Different Types of 20 Inch Water Filter Cartridges
PP Sediment Filter Cartridges
PP (Polypropylene) melt-blown filters are among the most common and cost-effective options. They remove sediment, dirt, sand, and rust particles. BasideWT’s PP cartridges use a multi-layer gradient density structure, capturing particles of different sizes throughout the depth of the filter.
For example, the outer layer traps larger debris (20 microns), while the inner core filters finer particles (1–5 microns). This design ensures longer service life and stable water pressure.
Carbon Block and GAC Cartridges
When the concern is taste, odor, or chlorine removal, carbon block or granular activated carbon (GAC) filters excel. The porous structure of activated carbon adsorbs chemical residues, VOCs, and unpleasant smells.
BasideWT carbon filters use high-quality coconut shell carbon, known for its excellent adsorption performance. Interestingly, coconut carbon has a 20% higher surface area than coal-based carbon, enhancing purification efficiency.
Pleated Filter Cartridges
Pleated filters increase surface area dramatically, allowing for high flow and lower pressure drop. They are washable and reusable, making them environmentally friendly and cost-efficient.
They are commonly used in applications where water has visible particulate matter but minimal chemical contamination.
Resin and Ceramic Cartridges
For specialized needs, resin filters remove hardness (calcium, magnesium) while ceramic filters eliminate bacteria and cysts. BasideWT offers a full line of customized 20 inch water filter cartridges compatible with these applications.

Applications of 20 Inch Water Filter Cartridges
Residential Filtration
For households with high water usage, a 20-inch cartridge ensures constant supply without frequent replacement. It’s ideal for whole-house filtration, removing sediment before water reaches faucets or appliances.
Commercial Use
Restaurants, cafés, and hotels require stable, high-volume filtration. Our 20 inch water filter cartridges protect coffee machines, dishwashers, and ice makers from scale and sediment buildup.
Industrial Systems
In industrial environments, filters handle heavy loads of particulates and chemicals. BasideWT cartridges are used in cooling systems, boiler feed water, and manufacturing lines, where water purity directly affects product quality.
Pre-RO Filtration
These cartridges are often used as pre-filters for reverse osmosis systems. By removing large impurities, they extend the life of RO membranes and improve overall system efficiency.
How to Choose the Right 20 Inch Water Filter Cartridge
Identify Water Quality
Determine the contaminants present. Is the problem sediment, chlorine, or hardness? Each issue requires a different cartridge type. For instance:
- Sediment → PP melt-blown
- Chlorine/odor → Carbon block
- Hardness → Resin-based
Match Flow Rate and Pressure
Ensure your filter housing and water system can maintain sufficient flow. Using a high-density filter in a low-pressure system can cause flow drop or filter stress.
Check Material Compatibility
Always verify that the cartridge material suits your application—especially for food, beverage, or laboratory use. BasideWT provides clear labeling and documentation for all materials.
Installation and Maintenance Tips
Installation Steps
- Turn off the water supply and release system pressure.
- Unscrew the filter housing using a wrench.
- Remove the old cartridge and clean the housing.
- Insert the new 20-inch filter cartridge, aligning it properly.
- Reattach the housing, ensuring the O-ring is seated correctly.
- Open the water supply slowly and check for leaks.
Maintenance Routine
- Replace cartridges every 6–12 months, or sooner if flow decreases.
- Clean housings regularly to prevent bacterial buildup.
- Store spare filters in a dry, cool place.
Interestingly, even the best cartridges lose efficiency over time, not due to damage but microscopic saturation of filter pores. Hence, routine replacement is essential.
Troubleshooting Common Issues
Low Water Flow
Low flow often means the cartridge is clogged. Replacing it typically resolves the issue. However, check upstream for sediment accumulation that could accelerate blockage.
Bad Taste or Odor
If filtered water tastes unusual, the carbon cartridge may be exhausted. Flush the system thoroughly after replacement to activate the new media.
Air in the System
Air bubbles after installation are normal. Run the water for several minutes to purge trapped air.
However, if bubbles persist, check all O-rings and connections for small leaks.
Comparison with Other Cartridge Sizes
| Feature | 10-Inch Filter | 20-Inch Filter |
|---|---|---|
| Lifespan | 3–6 months | 6–12 months |
| Flow Rate | 4 GPM | 8–20 GPM |
| Maintenance | Frequent | Less frequent |
| Ideal Use | Small homes | Large homes or commercial |
| Cost per Month | Higher | Lower |
Therefore, upgrading to 20 inch water filter cartridges offers both economic and operational advantages.
