Common Water Purifier Questions

Answers to common questions customers ask when choosing between countertop reverse osmosis filtration, replacement filters, and TDS testing.

Renters usually need a purifier that avoids drilling, under-sink installation, or permanent plumbing changes. A countertop reverse osmosis purifier like Nova 100 can be a practical option for rented homes, flats, offices, and shared spaces.

Is a countertop reverse osmosis water purifier better than a water filter jug?

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. Nova 100 is designed for customers who want a countertop water purification option without installing an under-sink system.

How can I test tap water and filtered water at home?

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