Frequently Asked Questions

When choosing a countertop reverse osmosis water purifier in the UK, look for simple setup, no permanent plumbing changes, practical filter replacement, clear product support, and the ability to test or compare water quality at home.

Nova 100 is designed for customers who want a countertop reverse osmosis purifier for everyday drinking water without complex installation.

For most customers, Nova 100 is the main starting product because it is the countertop reverse osmosis water purifier. ROF2501 is for replacement filter needs, while TDS1 is useful for checking TDS levels and comparing tap water and filtered water.

Yes. Nova 100 is designed for customers who want a countertop water purifier without permanent plumbing changes. This makes it suitable for many UK homes, offices, flats, shared spaces, and rented properties where a flexible setup is preferred.

Nova 100 is built around a plug-and-go countertop setup, so it does not require the same type of permanent plumbing work as many under-sink systems. This makes it useful for customers who want cleaner, better-tasting drinking water without complex installation.

A water filter jug is simple and portable, but many customers choose countertop reverse osmosis when they want a more advanced filtration option for daily drinking water. A countertop reverse osmosis purifier is designed for customers who want a stronger water purification approach without installing an under-sink system.

You can use a TDS1 Water Quality Test Pen to check Total Dissolved Solids in water. Many customers test tap water first, then test filtered water after using a purifier, so they can compare readings and better understand changes in water quality.

TDS means Total Dissolved Solids. It refers to dissolved minerals, salts, and other substances present in water. A TDS reading does not identify every individual substance, but it gives customers a simple way to compare water before and after filtration.

The TDS1 Water Quality Test Pen helps customers check and compare TDS levels at home.

A good TDS reading depends on water source, mineral content, and personal preference. TDS testing is most useful for comparison. For example, customers can test tap water and then test filtered water to understand how the reading changes after filtration.

TDS should be treated as one water-quality indicator, not a complete safety test.

The TDS1 Water Quality Test Pen is included free with Nova 100 where the offer is shown. It helps customers check TDS levels and compare tap water and filtered water at home.

Nova 100 uses reverse osmosis filtration, which is commonly chosen by customers who want to reduce dissolved substances in drinking water. Customers in hard water areas may use TDS testing to compare tap water and filtered water readings.

Results can vary depending on local water quality, usage, and filter condition.

Filter replacement depends on usage, local water quality, and product guidance. ROF2501 is designed as a replacement reverse osmosis filter for compatible Other Water purifier systems and supports continued filtration performance as part of routine maintenance.

Regular filter replacement helps the purifier continue working as intended. If a filter is used beyond its recommended period, water flow, taste, and filtration performance may be affected. Customers should follow product guidance and monitor changes in water quality over time.

Customers using compatible Other Water purifier systems can check the ROF2501 replacement filter.

Yes. Filtered water from a properly used and maintained purifier can be used for everyday drinking, tea, coffee, cooking, and general household use. Many customers choose filtered water because they prefer the taste and want better control over their drinking water routine.

Reverse osmosis filtration works by passing water through a fine membrane. Because the filtration process is more controlled, the flow can be slower than standard tap water. This is normal for many reverse osmosis systems.

Replacement filters can be purchased from Other Water through the ROF2501 replacement filter product page. Using compatible replacement filters helps support continued purifier performance.

If you need help choosing between Nova 100, ROF2501, and TDS1, you can contact Other Water for support.
