Frizzlife WB99-H Countertop Reverse Osmosis Filter (Silver, With Heating Function)

How often do I need to replace the filters?

The main FCR100+ reverse osmosis membrane lasts approximately 12 months or 900-1000 gallons, depending on your water quality. The SC90 alkaline filter requires replacement every 90 days or roughly 3 months. The system monitors filter life automatically and displays alerts when replacement is needed. Replacement costs average around £13.40 per month over a full year including both filters.

Does this system require professional installation?

No professional installation is needed. The WB99-H arrives fully assembled and ready to use. Simply plug into a standard electrical outlet, fill the 4.5-litre feed tank with tap water and the system begins producing filtered water immediately. However, you'll need to flush the system by filtering 3-5 full tanks of water on first use, which takes about 60-90 minutes total.

What contaminants does this system remove?

The 0.0001 micron RO membrane removes 99.99% of over 1000 contaminants including chlorine, fluoride, lead, mercury, arsenic, heavy metals, chloramine, volatile organic compounds, bacteria, viruses and dissolved solids. The system reduces TDS levels from typical tap water readings of 150-400 ppm down to 2-33 ppm. NSF/ANSI 58 certification validates the filtration performance.

How much water does the system produce and waste?

The 4.5-litre feed tank produces approximately 3 litres of filtered water, with about 1.5 litres discharged as waste water during the RO process. This 2:1 ratio is typical for reverse osmosis systems. The system can produce up to 100 gallons per day, though actual output depends on usage patterns and water pressure.

Can I adjust the water temperature precisely?

Yes, whilst there are three preset temperature modes, you can select any specific temperature between 45°C and 100°C using the "+" and "-" buttons on the touch panel. The system heats water instantly without waiting, making it perfect for brewing different beverages at their optimal temperatures. The last temperature setting is remembered until the power is switched off.

Is the water pitcher suitable for refrigerator storage?

The 1.4-litre pitcher can be refrigerated, though some users find it quite large for smaller UK fridges. It fits better in larger American-style refrigerators. The pitcher is BPA-free and designed for safe food storage. You can purchase additional pitchers to keep one chilled whilst another remains on the system for continuous use.

How noisy is the system during operation?

The WB99-H operates very quietly, producing minimal noise only when the pump activates for filtration or water dispensing. Most users report noise levels well below 50dB, comparable to a quiet library. The system doesn't run continuously - it only activates when producing water or dispensing, making it suitable for bedrooms, offices, or open-plan living areas.

What happens if I don't use alkaline water?

You can choose whether to use alkaline water by selecting the appropriate SC filter. The standard SC90 alkaline filter raises pH levels for health benefits, but Frizzlife offers non-alkaline versions if you prefer neutral pH water. The alkaline enhancement helps counteract the naturally acidic nature of pure RO water, making it more suitable for regular consumption and potentially better for long-term health.
