TDS is not a professional way to test the water quality, TDS means total dissolved solids. For example, if you put very little salt(NaCl) into the water and test the TDS, you will find the result is dramatically high. The same thing, if your water is full of minerals, the TDS is very high too.

The GX99 doesn’t remove any of the minerals from water, it only stops heavy metals such as Lead, Mercury, Cadmium, and over 70-80 VOCs, and it removes greatly the chlorine from water. Therefore, it is the reason why the TDS you get is not that lower as you expect.

TDS meter testing method is widely used in reverse osmosis systems since the RO filter system also removes minerals from water. If a RO membrane doesn’t have a good performance, the TDS will be relatively high. And if TDS is getting much higher, means it’s time to change the RO membrane.

So please do not use TDS to test any water except Reverse Osmosis System, because the result is meaningless.

This filter should be used in conjunction with municipally treated drinking water or water that has been properly disinfected before use. The water filter cartridge is manufactured with 0.01micron UF membrane filter that will get easily clogged up by any type of dirt or settlement from a well.

If you would like your refrigerator or ice maker to have clean and safe water from the Frizzlife filter system, we also have an IMC-1 icemaker kit available on our online store.

No. GX99 is an ultrafiltration under sink water filter system, not a reverse osmosis system. It uses a 0.01μm UF membrane to help reduce sediment, rust, large particles, and common taste concerns while retaining naturally occurring minerals. Users who specifically need dissolved solids or TDS reduction should compare Frizzlife reverse osmosis systems instead.

No. GX99 is not designed for TDS reduction because ultrafiltration does not remove most dissolved minerals or salts from water. This is intentional for users who prefer mineral-retaining filtration for everyday drinking and cooking. If low TDS water is the goal, a reverse osmosis system is the more suitable category.

GX99 focuses on physical impurity reduction and taste improvement for municipal tap water. Its 4-layer filtration structure is designed to help reduce sediment, rust, large particles, and common impurities that may affect clarity or taste.

GX99 is designed to deliver up to 1.18 GPM at 60 psi, making it a fast-flow under sink ultrafiltration system for daily kitchen use. Actual flow may vary depending on household water pressure, feed water conditions, installation quality, and filter condition. For best performance, replace filters on schedule and follow the installation guide.

No. GX99 does not require electricity because it uses household water pressure to deliver filtered water. As an ultrafiltration system, it does not use the same drain-water process as reverse osmosis systems. This makes it a simpler option for users who want non-electric under sink filtration without RO-style wastewater discharge.

GX99 uses a tool-free twist-and-pull filter replacement design. Users can rotate the used cartridge, remove it, and install the new one by aligning it with the lock position. This setup helps make maintenance faster and cleaner than systems that require complex tools or full housing replacement.

Yes. GX99 can support refrigerator or ice maker connection when used with a compatible connection kit such as IMC-1. This allows filtered water to support more than one kitchen use case, including drinking water, cooking, appliance supply, and ice making. Always confirm accessory compatibility before installation.
