ArkkZ Water Filter | Undersink Reverse Osmosis System | 800GPD

Water first goes through a pre-sediment PP membrane and a carbon block filter, removing contaminants like sand, rust, and chlorine. After running through another sediment membrane, the water is subjected to a multi-stage composite filter with a reverse osmosis membrane. This step reduces 90% of TDS (total dissolved solids), removes contaminants such as chemicals, bacterias/viruses and heavy metals, including arsenic and mercury. 

Renewell Water ArkkZ reverse osmosis systems can intercept most harmful contaminants including: TDS, chlorine, taste and odour, chloramine, scale and turbidity; carcinogens like chromium and cadmium; heavy metals like lead, mercury, barium, copper, radium and aluminium; micro organic contaminants like cysts; inorganic pollutants like arsenic and fluoride; and organic pollutants like asbestos, benzene, formaldehyde, PFOA and PFOS.

A traditional tank RO system makes water slowly — it takes one minute to produce two to three ounces of RO water, meaning you'd wait at least 5 minutes to fill a glass. Waterdrop's tankless RO system has overcome the issue of bacteria colonising in the bladder tank, and does not run until RO water is needed.

No. The ArkkZ System includes a professional installation nationwide (in Ireland and Northern Ireland). After the purchase, our team will contact you to book the suitable day and time to get it installed for free.

If you live outside Ireland and UK, you can Install it yourself by following the instruction manual and instructional videos, or by contacting support via email, phone, or live chat.

Generally, you should replace the pre-filter every 12 months. The RO membrane filter may last up to 24 months. The ArkkZ reverse osmosis system has smart notifications to remindyou when it is time to change the filters and Renewell Water also sends you emails to advise when the system is due to service.

With a 800 GPD large capacity, this reverse osmosis filter delivers clean water at a rapid flow, filling a 300ml cup within a mere 6-7 seconds. 

Reverse Osmosis systems do produce wastewater backwashing the membrane and flushing dirt water, which is collected in the drain and returned to the water treatment plant through the sewers. For households, the water can be diverted from the drain into household applications like laundry, gardening, household cleaning, car washing, and flushing toilets.

Yes, but only up to 300 ppm of incoming source water. RO water filters are indeed efficient at removing scaling caused by calcium and magnesium ions, but if you have very hard water in your area, a water softener is advised before the RO system. 

Yes. RO membranes can effectively reject microplastics and PFAS compounds in Ireland And UK, which are emerging problems in drinking water.

This undersink water filter saves 70% of under-sink space and eliminates the risk of bacterial secondary contamination from storage tanks, thanks to its tankless design. ArkkZ Dimensions: 39cm x 13.5cm x 39.5cm (L x W x H)

The twist-and-pull filter design allows replacement in just 3 seconds, making maintenance quick and simple without tools or complicated steps.

If you want to additionally remove contaminants that a water softener doesn't remove, then yes. However, if you want to remove the salty taste of softened water, a RO system is not recommended, because when water passes through a softener it increases salt concentration, making it much saltier than the source water.

If the TDS (total dissolved solids) value of your tap water is over 250, a reverse osmosis water filter system can improve the quality of your drinking water. If you don't have a TDS meter, you can determine the quality of your water based on whether limescale develops when the water is boiled or whether the water has an unpleasant odour.

Getting a reverse osmosis water system can guarantee a constant supply of clean and filtered water, at just pennies per gallon. The plastic bottles, used in bottled water, leave microplastic in the water and the bottles end up in landfills where they could take hundreds of years to decompose. 

The water filtered by the RO system is free of chemicals (as Chlorine) and heavy metals, which often affects the flavour of food. Similarly, RO water is more suitable for tea and coffee, and is free of heavy metals and organic compounds, making it ideal for drinking.

Yes. A high-quality water filter system can not only help newborns drink healthily but also improve the quality of drinking water for the whole family. It can also be used in combination with milk powder to prepare a milk drink for infants.
