Frizzlife PX500-A Reverse Osmosis System (Alkaline, 500 GPD)

How often do I need to replace the filters and what do they cost?

The first stage pre-filter (ASR311) needs replacement every 6 months, the RO membrane (ASR313-500G) every 2 years and the post-alkaline filter (ASR313-A) annually. Replacement costs vary but the system's filter life monitoring with colour indicators and audible alerts ensures you replace filters at optimal times, maximising their lifespan and maintaining water quality.

What water pressure do I need for this system to work properly?

The PX500-A operates within a pressure range of 43.5-100 PSI. Most UK homes have water pressure between 30-80 PSI, so the system should work in most installations. If your pressure is below 43.5 PSI, you may need a booster pump. The system performs best at 60 PSI, delivering the maximum flow rate of 0.4 gallons per minute.

Does this system require electricity and how much power does it use?

Yes, the PX500-A requires electricity to power the internal pump and monitoring system. It comes with a power adapter and plugs into a standard electrical outlet. The system only operates when water is being drawn, making it energy efficient. The power consumption is minimal, similar to a small household appliance and the pump automatically shuts off when not in use.

Can I connect this system to my refrigerator's ice maker?

Yes, the PX500-A can be connected to your refrigerator ice maker using an additional ice maker connection kit (sold separately). This provides filtered water for ice production, ensuring your ice cubes are free from contaminants and taste better. The connection requires additional tubing and fittings specific to your refrigerator model.

How much space do I need under my sink for installation?

The tankless design measures 35.6cm length x 45.7cm width x 12.7cm height, making it significantly more compact than traditional RO systems with storage tanks. You'll need enough space for the unit plus clearance for filter changes and connections. Most standard kitchen sinks have adequate space and the compact design leaves room for other under-sink storage.

What contaminants does this system remove and what doesn't it filter?

The system removes 99.99% of over 1000 contaminants including fluoride, chlorine, chloramine, lead, heavy metals, total dissolved solids (TDS) and limescale. The 0.0001 micron RO membrane blocks virtually all dissolved contaminants. However, some customers report that limescale may still appear in kettles after extended use, suggesting the system may not eliminate 100% of all minerals.

How does the alkaline remineralisation work and why is it beneficial?

The post-alkaline filter uses natural mineral particles that mimic mineral stones found in spring lakes. After the RO membrane removes contaminants, this stage adds back essential minerals like calcium and magnesium whilst raising the pH above 7.5. This creates alkaline water that many believe offers health benefits and tastes better than pure RO water, which can taste flat.

Is the installation really DIY-friendly for someone with basic skills?

Yes, the integrated design with pre-loaded filters simplifies installation significantly. The package includes all necessary components: faucet, tubes, fittings and adapters for different connection sizes. Most customers complete installation in 30 minutes to 2 hours following the video guide. The main requirements are basic tool use, drilling a hole for the faucet (if needed) and connecting water lines under the sink.
