HF03 Composite Filter Element for W100

4-in-1 Filter Cartridge
This Hydrofast HF03 integrated filter cartridge effectively filters out impurities, particulate heavy metals and harmful substances, removes odors, and keeps your drinking water safe, healthy and refreshing.

Polypropylene Sediment Filter
The first filtration layer consists of a polypropylene sediment filter. It acts as a strong initial barrier, effectively intercepting red worms, rust and various particles of impurities, protecting the subsequent filtration stages and improving the overall water quality.

Effective Adsorption of Harmful Substances
The second layer uses CTO-sintered activated carbon, which not only effectively removes harmful organic particles and other particulate matter but also eliminates residual chlorine and particulate heavy metals.

Activated Carbon and PCF
The third layer contains activated carbon and PCF material with an average pore size of 2nm, which has high adsorption capacity and fast adsorption speed to further remove odors. The fourth layer is rich in minerals, containing calcium, magnesium, sodium, and potassium, which make the water taste smooth, sweet, and refreshing.

Easily Replaceable and Compatibility
Our HF03 cartridge measures 73 x 320mm and is designed specifically for the Hydrofast W100 water purifier to ensure optimal performance and water quality. To ensure that you can always drink safe and healthy water, we recommend that you replace your filter cartridge every 9 months.
