Its main drawback is the slow flow rate and the need for regular cleaning and careful handling due to material fragility. I recommend! Review: It works with Santevia Gravity Water System. - I received this ceramic filter yesterday and after over 24hrs of filtration, I can confidently say that it works with my Santevia gravity water system. ## Features - 💎 PORE SIZE of 0.2 to 0.5 micron (human hair is 40 to 300 microns) In other words, the stated pore size of filter isn’t literally the size of the pores. It’s a rating of what can’t pass through them. Obviously, when sterilizing water, the object is to physically remove particles suspended in the water. The smaller pore size a smaller amount of contaminates will pass them - 💎 SILVER IMPREGNATED A low-cost technology to treat water at the household level is the ceramic silver-impregnated filter. The ceramic filter is a promising treatment system to supply safe drinking water especially to people living in rural areas - 💎 REMOVES: impurities and volatile organic chemicals. This Filter Removes up to of following contaminates: 99% of Arsenic 5, Taste, Odor & particles larger than 0.3 micron; 98% of Aluminum, Lead & particles larger than 0.2 micron; 96% of Iron. TRAPS: dirt, sediment, contaminants, debris - 💎 LIFE OF FILTER is 1000 gallons or 1 year whichever comes first. To achieve better results recommended maintenance is at least once a month, or as often as necessary, depending on the quality of water. Over time, the trapped dirt and contaminants will begin to buildup, forming a layer of gunk on the surface of the ceramic filter. Scrubbing the surface of the ceramic dome with a scouring pad or soft brush under cool running water will unclog the pores on ceramic and expose a new layer for use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071VDQFS6 | | Best Sellers Rank | #106,540 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #113 in Replacement Countertop Water Filters | | Brand | Ronaqua | | Brand Name | Ronaqua | | Customer Reviews | 4.2 out of 5 stars 512 Reviews | | EU Spare Part Availability Duration | 1 Years | | External Testing Certification | FDA | | Included Components | filter | | Item Dimensions D x W x H | 3"D x 3"W x 3"H | | Item Type Name | filter | | Item Weight | 8 Ounces | | Manufacturer | Ronaqua | | Manufacturer Part Number | RA-1CE-S | | Material | Ceramic | | Material Type | Ceramic | | Model Number | RA-CD | | Number of Items | 1 | | Product Benefits | To physically remove particles suspended in the water. | | Product Dimensions | 3"D x 3"W x 3"H | | Set Name | Zen Water System | | Unit Count | 1 Count | ## Product Details - **External Testing Certification:** FDA - **Item Weight:** 8 Ounces - **Material:** Ceramic - **Product Benefits:** To physically remove particles suspended in the water. - **Product Dimensions:** 3"D x 3"W x 3"H ## Images ![Replacement Ceramic Dome Water Filter 0.2 to 0.5 micron for Countertop & Water Coolers.
