Bottled water can feel convenient at first. You buy a pack, bring it home, store it in the kitchen or fridge, and use it whenever you need drinking water. But over time, the routine can become expensive, bulky, and repetitive.
Filtered water is different. Instead of buying bottles again and again, you use the tap water already available at home and filter it for a better everyday drinking-water routine.
Quick answer: is filtered water cheaper than bottled water?
For many UK homes, filtered water can be cheaper over time than regularly buying bottled water. The exact difference depends on how much water your household drinks, what bottled water you buy, and which filter system you use.
Bottled water has a low upfront cost, but the cost repeats every week. A filter jug or countertop purifier has an upfront setup cost, but it can reduce the need for repeated bottled-water shopping.
The hidden cost of bottled water
The price on the shelf is only part of the bottled-water cost. You also need to think about carrying packs home, storing bottles, recycling plastic, and remembering to buy more before you run out.
For flats and smaller kitchens, storage can become a real issue. Bottles take cupboard, floor, fridge, or hallway space that could be used for something else.
Filtered water costs: what should you include?
Filtered water costs depend on the type of system. A filter jug usually has a low entry cost and regular cartridge replacement. A countertop water purifier has a higher upfront cost but can support a more complete daily drinking-water setup.
When comparing filtered water costs, include:
- The initial product cost
- Replacement filters or cartridges
- How often your household drinks filtered water
- Whether it replaces bottled-water shopping
- Convenience, storage, and daily routine

Why flats and renters should compare no-plumbing options
If you rent or live in a flat, you may not want an under-sink system that needs installation. You may also have limited counter, fridge, or cupboard space.
No-plumbing options can be more practical because they do not require drilling or permanent changes. If you want to compare product choices, start with our countertop water purifiers for UK homes.
When a countertop purifier may make sense
A countertop purifier may be worth considering if you buy bottled water every week, dislike your tap-water taste, have limited storage space, or want a more consistent drinking-water routine at home.
The Nova 100 countertop reverse osmosis water purifier is designed for UK homes, flats, renters, and smaller kitchens where under-sink installation is not practical.
What about filter replacement costs?
Any filtered-water setup needs maintenance. Filter performance depends on correct use, water conditions, and replacement timing. When comparing costs, check how often filters need to be replaced and what replacement filters cost.
For compatible Other Water purifier use, review the ROF2501 replacement filter and current product guidance before buying.
FAQs
Is bottled water cheaper than filtered water?
Bottled water may feel cheaper per purchase, but the cost repeats every week. Filtered water may be cheaper over time for households that regularly buy bottled water.
Does filtered water reduce plastic waste?
Filtered water can reduce reliance on single-use bottles when it replaces regular bottled-water buying. The exact impact depends on your household routine.
Is a filter jug cheaper than a countertop purifier?
A filter jug usually has a lower upfront cost. A countertop purifier may make more sense if you want a fuller daily setup and do not want to rely on bottled water.
Can renters use a countertop water purifier?
Yes, if the purifier is designed for countertop use and does not require permanent plumbing changes. Renters should still check space, power access, refill routine, and maintenance needs.
Final thoughts
Bottled water is useful for travel, emergencies, and occasional convenience. But for everyday home drinking water, repeated bottled-water buying can become expensive and inconvenient.
If you want to reduce bottled-water routines at home, compare no-plumbing filtered-water options first. Start with our countertop water purifiers for UK homes, including Nova 100, replacement filters, and TDS testing tools.
