【Filter Precision Up to 1 Micron】 To achieve excellent filtration performance, this filter element uses high-quality activated carbon from coconut shells as the filter material, with a filtration precision of up to 1 micron. It effectively removes various contaminants such as sand, rust, sediment, and odors, while also efficiently absorbing residual chlorine with a removal rate of over 99%. 【Compatible Models】 This filter can replace water filters. It is compatible with gravity filtration systems, including Travel, Grand, Royal, Imperial, and Crown series. The precise design of the packaging and wing nut ensures a secure connection and prevents leaks. No priming is required, and it can be installed and used immediately after replacement, saving time on flushing work. No issues with low flow. 【Long-Lasting Lifespan】 To extend the lifespan of the equipment and achieve optimal performance, we recommend replacing the filter every 6,000 gallons (depending on the quality of the tap water). Note that the carbon filter must be fully submerged once a week to allow the drip system to function normally. 【Cost-Effective and Affordable】 Why pay four times the price for a brand? This filter provides the same level of filtration and performance as branded filters, but at a more affordable price. Choose us, and enjoy the benefits of high-quality water filtration while keeping costs manageable and cost-effective. 【Note】 Before installing the filter, wipe and clean it to remove any residual manufacturing dust.
