Nova 100 is a plug-and-go countertop reverse osmosis water purifier designed for UK homes, offices, flats, and renters. It helps provide cleaner, better-tasting drinking water without complex installation or permanent plumbing changes.
This product also includes the TDS1 Water Quality Test Pen free where offered, helping customers check TDS levels before and after filtration and compare tap water with filtered water at home.
TDS note: A TDS reading is a simple dissolved-solids reading. It does not replace a full water-quality or safety assessment.

• Suitable for UK homes, offices, flats, and renters
• No permanent plumbing changes required
• Helps improve everyday drinking water taste and quality
• Includes TDS1 Water Quality Test Pen free where offered

Space and everyday use
Choose Nova 100 if you want a countertop reverse osmosis water filter for a UK home or rented flat without permanent plumbing. Check your available worktop space before ordering: the unit measures 270 mm deep × 200 mm wide × 410 mm high and weighs 5.1 kg. Allow additional room for access, refilling and cleaning.
Everyday use
-
Before first use: follow the supplied manual and run two full tanks through the new machine to flush it.
-
Filtration speed: the published filtering rate is 0.2 litres per minute. This is a filtration specification, not a promise that every cup dispenses at that speed.
-
Temperature options: room temperature, 45°C, 85°C and 95°C, as listed in the product specifications.
-
Power: a 220–240 V supply is required. The published 2100–2400 W rating applies when heating; it should not be treated as continuous electricity consumption.
Replacement filters and running costs
Nova 100 uses the ROF2501 reverse osmosis replacement filter. The current listed cartridge price is £49.99; check the filter page for the latest price and availability. Follow the product manual for replacement guidance, as usage and source-water conditions affect filter life. The rated total filtering volume of 2,000 litres is a specification, not a guaranteed replacement interval for every household.
To compare ownership costs, include the machine, replacement cartridges, electricity and water. At the current £199 machine price, spreading the purchase over 365 days gives approximately £0.55 per day for the machine alone. This example excludes filters, electricity, water and any delivery charges; it is not a total running-cost or savings claim.
Compare before you buy
A filter jug may suit a lower upfront budget; an under-sink system may suit a home where permanent installation is acceptable. Read our guide to choosing a water filter for a rented flat to compare setup, space and maintenance.
