Normally for the first time use of the RO system, the water seems to have white bubbles in it, which is normal and totally drinkable. It is because when the pump is pressurizing the water, it will pressurize the air at the same time. It will make the air molecules smaller, thus the solubility further increases. The air canít be released at that time because of the pressure in the RO system. However, when you turn on the tap to get a cup of water, the pressure of air is released. So you will see a huge number of bubbles in the water. It looks cloudy and white, but they are just bubbles. After you put the water still for a while, all bubbles will be gone, the water is totally good for drinking.

The first two stages of the system are able to eliminate more than 99.99% of all substances from your tap water, removing more than 94% of TDS value. The pure water then goes through the 3rd remineralized stage of the system which restores essential minerals, adjusts PH level and further polishes the water taste, serving customers with optimal water solution. However, the essential elements such as calcium and magnesium may raise the TDS value of the water again. If you consider the remineralized water to be undesirable, please contact us for an exchange of the last alkaline filter to post carbon filter.

Osmosis is a natural phenomenon happens in all RO system, no matter if you have a conventional RO system or tankless RO system. When the RO system starts to work, pressure from the pump overcomes natural osmotic pressure, forcing feed water through the RO membrane that removes the impurities. When the RO system stops working, the pump stops offering pressure as well. At that time, because of different concentrations, a small fraction of ions will enter into pure water and cause TDS to rise by a small amount. However, even if the TDS reading is a little high at the beginning, the quality water is still unbeatable by any other filtration methods including carbon, KDF, ceramic, UF, UV, etc.. The water is totally good to drink and you donít have to wait for about 1 minute to get the water, since the whole system will not release any harmful substances to the water. The TDS removing rate for PX600 is about 94-95%, if your incoming TDS is high, the outlet TDS will be high too.

Maybe you have plugged the power cord into the socket specially designed for garbage disposal, please change another socket.

PX600 is designed with a 600 GPD water production capacity for households that need higher daily filtered water output. This makes it suitable for frequent drinking water use, cooking, coffee, tea, and kitchens that may also connect filtered water to a refrigerator or ice maker with the right accessories. Actual flow performance depends on water pressure, temperature, filter condition, and installation setup.

No. PX600 uses a tankless design that produces filtered water on demand without a traditional storage tank. This helps save under-sink space and reduces the cabinet footprint compared with tank-based RO systems.

PX600 uses an 11-stage filtration design with a 0.0001 micron reverse osmosis membrane as part of its filtration process. This supports cleaner-tasting household drinking water and helps address many common water concerns.

Yes. PX600 can support refrigerator and ice maker connection when used with the appropriate Frizzlife fridge kit or compatible accessories. This is useful for households that want RO filtered water available from both the dedicated RO faucet and compatible refrigerator dispensers. Users should confirm connection accessories, installation distance, and compatibility before setup.

Yes. PX600 includes a smart LED display that shows real-time TDS information and filter status. This helps users understand system operation and plan filter replacement more easily.

PX600 is suitable for households with higher daily filtered water demand because it combines 600 GPD capacity with a tankless under-sink design. Families that frequently use filtered water for drinking, cooking, beverages, and refrigerator connection may benefit from the higher output. Actual performance still depends on household water pressure, temperature, and filter condition.

PX600 uses reverse osmosis filtration technology, which is commonly used in household water treatment to help reduce various dissolved substances.

PX600 filter replacement frequency depends on feed water quality, daily usage, and operating conditions.

PX600 is designed for convenient installation in standard kitchen setups, but users should confirm plumbing compatibility before installation. The system uses under-sink water and drain connections, so installation difficulty can vary by cabinet space, faucet configuration, and existing plumbing. Users who are not comfortable working with water lines should consider professional installation.

PX600 is best for users who want a high-flow 600 GPD tankless RO system with smart TDS monitoring, refrigerator or ice maker connection support, and a compact under-sink footprint.
