GAC and PP Composite Water Filter Cartridge

Product Introduction

The GAC and PP filter cartridge is an advanced two-stage water filter that combines two essential technologies into one efficient unit. It has an outer layer of granular activated carbon (GAC) for chemical adsorption, wrapped around a solid polypropylene (PP) core for mechanical filtration. This carbon and sediment filter is designed to reduce chlorine, improve taste and odor, and remove dirt, rust, and other particles all at once—giving you comprehensive water pretreatment.

Product Advantage

• Dual-action filtration – This unique design provides two-stage purification in one cartridge. The GAC layer effectively adsorbs chlorine, VOCs, and organic chemicals, while the PP core mechanically traps suspended solids and sediments.

• Superior taste and odor improvement – The generous amount of high-quality granular activated carbon offers a large surface area for adsorption, giving you exceptional reduction of unpleasant tastes and odors from chlorine and other common water contaminants.

• Cost-effective solution – By combining two filtration stages into a single replacement cartridge, it simplifies maintenance and takes up less space. Great value and performance.

• Ideal pre-filtration – As a solid pre-filter for RO systems, it protects the delicate reverse osmosis membrane from both chlorine damage and particle fouling, which significantly extends the membrane's lifespan.

Product Uses

• Residential point-of-entry – A great choice for a whole-house composite filter. It treats all the water coming into your home, giving you cleaner, better-tasting water for drinking, bathing, and washing.

• Food and beverage industry – Used in kitchens, coffee shops, and restaurants to pretreat water, improving the taste of beverages and food, while protecting equipment from scale and sediment.

• Pre-treatment for sensitive equipment – Installed before UV sterilizers, ion exchange units, and other sensitive water treatment devices to remove chlorine and particles that could cause damage or reduce efficiency.

Product Operate Guide

1. Turn off the water supply and depressurize the filter housing.

2. Remove the old filter cartridge and dispose of it properly.

Rinse the new GAC and PP filter briefly with water to remove any loose carbon fines.

3. Insert the new cartridge into the housing.  ensuring it is seated correctly.

4. Reassemble the housing.  turn on the water supply slowly.  and flush for 5-7 minutes until the water runs clear.

FAQ

Q: Does it remove fluoride or heavy metals?

A: No, its primary functions are chlorine reduction and sediment removal. For fluoride or heavy metals, a specialized filter like an RO system or activated alumina is required.

Q: How often should it be replaced?

A: Replacement is typically needed every 6-9 months, depending on water quality and usage. A drop in water pressure or a return of bad taste indicates it's time for a change.
