1What's the difference between RO and UV water purifiers?
RO purifiers use membrane filtration to remove dissolved salts and minerals, making them ideal for hard water areas common in the UAE, while UV purifiers use ultraviolet light to kill bacteria and viruses but don't remove dissolved impurities. Choose RO if your water is hard or brackish; UV works better as a secondary stage after RO or for already-clean water sources.
2How do I know what storage capacity I need?
A 7-10 litre tank suits small families or offices with modest daily usage, while 15-20 litre tanks work better for families of 4+ or high-demand households. Consider that RO purifiers produce water slowly, so larger tanks mean less wait time between refills.
3What maintenance costs should I budget for?
Filter replacements are the main ongoing expense—typically every 6-12 months depending on water quality and usage, with costs varying by brand and filter type. Budget for annual servicing as well, especially in the UAE where water quality and dust levels affect filter lifespan faster.
4Is it worth paying more for a smart or tankless purifier?
Smart purifiers with app monitoring and auto-alerts are convenient for tracking filter life, but they're not essential unless you value that convenience. Tankless models save space and offer instant filtered water, but they're pricier and slower at delivering large quantities compared to tank-based systems.
5Should I test my tap water before buying a purifier?
Yes—knowing your water's TDS (total dissolved solids), hardness level, and contaminants helps you pick the right filtration technology; many suppliers offer free water testing. This prevents buying an over-engineered or under-spec system for your specific water conditions.
