NSF/ANSI 42

Improve Taste, Odor, and Aesthetic Water Quality
NSF/ANSI 42 applies to drinking water treatment systems certified to reduce aesthetic, non-health-related impurities. These may include chlorine taste and odor, unpleasant smell, and other factors that affect how water tastes, smells, or looks.
A product certified to NSF/ANSI 42 is typically chosen to improve the everyday drinking experience. However, this standard is not intended to verify reduction of health-related contaminants such as lead, arsenic, or PFAS unless those claims are certified under another applicable standard.

FAQ

Does it come with a set of filters inside?

Yes, the integrated system package comes with two filter catridges loaded. 

Does it come with a faucet or do i need to buy an extra one?

There is a RO faucet included in the package which is stainless steel faucet with brushed nickel finish. Frizzlife also provides a matte black finish choice.

Can the system be hooked up to refrigerator?

Yes, the unit can be hooked up to your refrigerator/ice-maker by using Frizzlife IMC-1 kit. Please kindly note, if the distance between the filter and the appliance exceeded 15 ft, you might need a mini tank to boost up the water pressure. Search "Frizzlife Mini tank" to purchase the mini tank.

Does the system need the eletricity to run?

Yes, please make sure you use universal power outlet to plug in the system, instead of using the typical outlet for garbage disposal.

What is the thread length of the faucet? Do you provide extended stem for the faucet if it is not long enough for my granite?

The thread of the faucet is 1.5 inch (3.8cm). If your granite is thicker than that, please simply send us your full shipping address for delivery of longer stem through our website, email. 

What is the difference of this unit from the APEC ones? It is more expensive and what are the main advantages?

The unit is innovative tankless RO system which has several key features that outperform the conventional tank systems:
- High capacity- ensures tankless design, fast water flow, and instant fresh water.
- No tank - integrated unit, no secondary storage pollution, easy to DIY install, less leakage, occupy less places.  
- Low drain ratio - less waste water, save water bill in long term
- Easy to change - twist in design. No more plumber required.

What is the pure:drain ratio? Is there a way for zero waste water plan?

The pure drain ratio of the PX500-A is at 1.5:1. By producing 1 cup of pure water, only 2/3 cup of water would be wasted. It can save up to 450% water when compared to universal traditional RO system.

What is the pH level of the output water? Does it include an alkaline filter?

The 3rd stage of the RO system is the alkaline and remineralized post filter. It could adjust the pH level by adding back beneficial minerals, and further polish the RO water taste. The final pH level would be slightly alkaline around 7.5-8.5.

Where can i find the replacment filters?

Please search ASR311 for the 1st stage of PX500-A, search ASR212 for the 2nd stage of PX500-A, search ASR313-A for the 3rd stage of PX500-A. 

Does the filter remineralize water after purification?

The 3rd stage of the RO system is the alkaline and remineralized post filter. It could adjust the pH level by adding back beneficial minerals, and further polish the RO water taste. The final pH level would be slightly alkaline around 7.5-8.5.

Can it be used with hard water?

Yes, with 0.0001 micron filtration accuracy, the system could remove over 94% of TDS from water, including the hardness. However, the large particles in hard water may block the system very easily. To prolong the service life of the filters, we would highly recommend you to install a pre-filter or water softener before the RO system. Or you are suggested to change the 1st stage of the system more frequently.

What if there is a power cut risk when the storm comes? Any tips to protect the system from the power cut damage?

The maintenance of the reverse osmosis system is quite similar to general appliances. Simply unplug/cut off the power supply when storm comes and replug it afterwards. If you have any further questions, please feel free to contact us.

Does the system remove fluoride?

Yes, by adopting RO membrane at 0.0001 micron filtration precision, the system is able to remove more than 99.99% of the harmful contaminants from your tap water, including fluroide.

How often do i need to change the filters? 

The first stage and the 3rd stage are recommend to change per 6 months, the second stage is recommended to change every two years. Please kindly note that the actual filter life highly depends on your tap water quality and water use frequency.

If you have any further questions, please feel free to contact us at support@frizzlife.com

What type of system is PX500-A?

PX500-A is a 500 GPD tankless reverse osmosis system designed for under-sink installation. It produces RO filtered water without using a traditional storage tank, which helps save cabinet space and keeps the installation more compact.

Does PX500-A include remineralization?

Yes. PX500-A includes a remineralization post-filter designed to improve the taste characteristics of RO filtered water after reverse osmosis filtration.

What does 500 GPD mean for daily use?

500 GPD refers to the system’s rated daily water production capacity under supported operating conditions. In practical use, this helps provide faster filtered water output for drinking, cooking, coffee, tea, and meal preparation compared with lower-capacity systems. Actual flow can vary based on feed water pressure, temperature, filter condition, installation setup, and household water conditions.

What is the pure-to-drain ratio of PX500-A?

PX500-A uses a 2:1 pure-to-drain ratio design, meaning it can produce about 2 cups of purified water for every 1 cup of drain water under supported conditions. This helps reduce wastewater compared with many traditional RO setups.

Does PX500-A need a storage tank?

No. PX500-A uses a tankless design instead of a traditional pressure tank. This helps save under-sink space and can make the cabinet area easier to organize. Tankless systems produce filtered water on demand, so they are especially useful for kitchens where users want RO filtration without giving up a large amount of cabinet room to a storage tank.

How often should PX500-A filters be replaced?

The recommended replacement schedule is ASR311 about every 6 months, ASR312-500G RO membrane about every 2 years, and ASR313-A about every 12 months. Actual filter life depends on feed water quality, daily usage, and operating conditions. Users should follow the product manual and filter life reminder instead of treating replacement intervals as guaranteed in every home.

Can PX500-A connect to a refrigerator or ice maker?

Yes. PX500-A can support refrigerator or ice maker connection when used with the appropriate connection kit or compatible accessories. This setup is helpful for kitchens that want RO filtered water available from both the dedicated faucet and a refrigerator dispenser or ice maker. Users should confirm accessory compatibility, installation distance, and water pressure requirements before setup.

Can I install PX500-A myself?

PX500-A is designed with DIY-friendly installation guidance, including product manual and installation video support. Users should still confirm that their under-sink space, faucet setup, feed water connection, and drain connection are compatible before installation. If plumbing conditions are unusual or the user is not comfortable working with water lines, professional installation is the safer choice.

Does the TDS display prove the water is completely safe?

No. TDS information is useful for understanding total dissolved solids, but it does not measure every possible contaminant or every aspect of water quality.

Who is PX500-A best for?

PX500-A is best for users who want a compact under-sink RO system with 500 GPD capacity, tankless installation, remineralized taste, and a lower drain ratio design. It is a stronger fit for households that want RO filtered water for drinking and cooking while also wanting to save cabinet space compared with traditional tank-based RO systems.
