When the DI filter element sends out rotten egg taste, it means that the filter element has been filtered for a long time and has reached a saturated state. Continued use not only affects the water quality and taste, but also may reduce the filtration effect. Please replace with a new filter element for more secure water. Generally, the DI filter can be used for 3-6 months. Please note the connection only after the RO machine. If direct filtration of tap water or well water, the filter element life will be very short - Filter Lifespan: Filter life time is 6-12 months depending on usage amount and feed water quality ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0897G8QDV | | Best Sellers Rank | #88,825 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #150 in Under-Sink & Countertop Filtration | | Brand | Geekpure | | Brand Name | Geekpure | | Capacity | 100 Gallons | | Container Type | Carton Box | | Customer Reviews | 4.3 out of 5 stars 535 Reviews | | EU Spare Part Availability Duration | 1 Years | | Global Trade Identification Number | 00726962550567 | | Included Components | 4 x filters,diverter valve,wrench,fittings,water pipe,clips | | Installation Type | Surface-Mounted,Easy and self installation | | Item Dimensions L x W x H | 14.8"L x 5"W x 9.2"H | | Item Weight | 2.9 Pounds | | LowerTemperature Range | 40 Degrees Fahrenheit | | Manufacturer | Geekpure | | Material | Polypropylene and Carbon filter and RO membrane (Material:Polyamide,,Polysulfone and Non-woven fabric) Material Polypropylene and Carbon filter and RO membrane (Material:Polyamide,,Polysulfone and Non-woven fabric) See more | | Material Type | Polypropylene and Carbon filter and RO membrane (Material:Polyamide,,Polysulfone and Non-woven fabric) | | Maximum Flow Rate | 380 Liters Per Day | | Model Name | RO-100G-4 | | Model Number | RO-100G-4 | | Operating Pressure Range | 40-100 PSI | | Other Special Features of the Product | Total 4 pieces filters is included | | Part Number | Geekpure RO-100G-4 | | Power Source | Feed Water Pressure | | Product Dimensions | 14.8"L x 5"W x 9.2"H | | Product Shelf Life | 3 Years | | Purification Method | reverse osmosis,Reduce TDS,Heavy Metal,Arsenic,Lead,Mercury,Fluoride ,Chlorine and more | | Special Feature | Total 4 pieces filters is included | | Supported Water TDS Level Maximum (PPM) | 1000 | | UPC | 726962550567 | | Unit Count | 1.0 Count | | Upper Temperature Rating | 110 Degrees Fahrenheit | | Warranty Description | 1 Year | ## Product Details - **Brand:** Geekpure - **Capacity:** 100 Gallons - **Included Components:** 4 x filters,diverter valve,wrench,fittings,water pipe,clips - **Installation Type:** Surface-Mounted,Easy and self installation - **Package Information:** Carton Box - **Power Source:** Feed Water Pressure - **Product Dimensions:** 14.8"L x 5"W x 9.2"H - **Purification Method:** reverse osmosis,Reduce TDS,Heavy Metal,Arsenic,Lead,Mercury,Fluoride ,Chlorine and more - **Special Feature:** Total 4 pieces filters is included ## Images ![Geekpure 4 Stage Portable Aquarium Reverse Osmosis RO Drinking Water Filtration System 100 GPD - with DI Filter TDS Close to 0 ppm - Image 1](https://m.media-amazon.com/images/I/61TB9EttolL.jpg) ![Geekpure 4 Stage Portable Aquarium Reverse Osmosis RO Drinking Water Filtration System 100 GPD - with DI Filter TDS Close to 0 ppm - Image 2](https://m.media-amazon.com/images/I/71WFwyOOvKL.jpg) ![Geekpure 4 Stage Portable Aquarium Reverse Osmosis RO Drinking Water Filtration System 100 GPD - with DI Filter TDS Close to 0 ppm - Image 3](https://m.media-amazon.com/images/I/813WQ1LhepL.jpg) ![Geekpure 4 Stage Portable Aquarium Reverse Osmosis RO Drinking Water Filtration System 100 GPD - with DI Filter TDS Close to 0 ppm - Image 4](https://m.media-amazon.com/images/I/61pYwA3Ai4L.jpg) ![Geekpure 4 Stage Portable Aquarium Reverse Osmosis RO Drinking Water Filtration System 100 GPD - with DI Filter TDS Close to 0 ppm - Image 5](https://m.media-amazon.com/images/I/71X+nRF97xL.jpg) ## Questions & Answers **Q: where can I download the user manual?** A: please download from following link, https://m.media-amazon.com/images/I/B1qJiDcBL7S.pdf or get back to seller, we will send it to you by mail. **Q: Where can i get b07g42fgjl that is no longer available on amazon.com?** A: yes, it is shortage now. new batch goods is on the way,please get back to purchase on Jan. if urgent to replace,please choose other brand. size at 2"x10".inlet/outlet is 1/4"thread.
