HF04 5-in-1 Composite Filter for C300
5-in-1 Filter Cartridge
This Hydrofast HF04 integrated filter cartridge effectively removes impurities, heavy metals, and harmful substances, while eliminating unpleasant odors to deliver safe, healthy, and refreshing drinking water.
Polypropylene Sediment Filter
The first layer employs a polypropylene sediment filter as a robust primary barrier, effectively removing sediment, rust, and various particulate impurities. This protects subsequent filtration stages and enhances overall water quality.
CTO Filtration & Advanced RO Membrane
The second layer utilizes a coconut carbon block filter (CTO). This not only effectively removes harmful organic particles and other suspended matter but also eliminates residual chlorine and heavy metals. The advanced reverse osmosis membrane boasts a filtration precision of 0.0001μm, effectively filtering out 99.99% of bacteria, viruses, and chemical contaminants, delivering purer, healthier water.
Post-Carbon & Remineralization Composite Layer
The fourth layer features a post carbon filter with an average pore size of 2nm, offering high adsorption capacity and rapid absorption properties to further eliminate chlorine, odors, and chemical substances. The fifth layer employs a mineral filter to enrich water with minerals such as calcium, magnesium, sodium, and potassium, while balancing pH levels. This results in water with a smooth, sweet taste and a refreshingly pleasant character.
Convenient Replacement & Compatibility
The HF04 filter cartridge measures ø88*377mm, which is specifically engineered for the Hydrofast C300 countertop water purifier to ensure optimal performance and water quality. This guarantees you consistently enjoy safe, healthy, purified water. The cartridge has a standby lifespan of 12 months.
