RO Water Purifier Price in Nepal 2026

How to Choose a Water Purifier for Kathmandu Water

The right purifier depends on where your water comes from. Many Kathmandu homes mix sources: KUKL or Melamchi line water when supply runs, tanker water when it does not, and boring or well water stored in an underground tank. Line water is treated at source but can pick up dirt in old pipes and storage tanks. Tanker and groundwater vary widely and are often hard, high in dissolved solids or iron, and can carry bacteria.

A simple TDS meter reading on your tap water is a useful first step before choosing a filter type:

• RO (reverse osmosis): removes dissolved salts, hardness and many metals as well as germs. The right choice for tanker, boring or well water and any supply with high TDS.
• UV: kills bacteria and viruses but does not remove dissolved solids, hardness or iron. Works on clear, low-TDS water, or as an extra stage after RO.
• UF: a membrane that filters particles and germs without electricity, but it also leaves dissolved solids untouched.
• Mineral or alkaline stage: RO removes minerals along with impurities, so an alkaline cartridge adds some back and improves taste.
• Very muddy or iron-heavy water: a separate sediment or iron pre-filter on the main line protects the RO membrane. Ask us if your water stains buckets orange.

Mineral RO Purifier Models Compared

All our purifiers are RO-based. They differ mainly in capacity, hot-water features and storage.

• ULTRA RO500B: multi-stage RO with an alkaline stage, 12.11 L storage tank and 11.8 L/hour output, without hot-water features.
• ULTRATEC RO-730D and ULTRA RO-730D (Sky Blue): 6 stages (PP, GAC, CTO, RO, T33, Alkaline), 7 L tank and hot water.
• ULTRATEC RO-730F: RO + UV + Alkaline in 6 stages, with voice broadcast to guide users.
• ULTRA Pure L-RO730E: RO + UV + Alkaline in 6 stages with a 700W heater for hot water.
• ULTRA RO-730C: 7 stages including UV and alkaline, with hot, cold and normal water and a vegetable detoxifier.
• ULTRA L-RO801: RO filtration with a 2270W instant heater giving hot water in about 3 seconds at 4 levels, plus a TDS display and 8 L tank.
• ULTRA L-RO650A: tankless, filtering on demand at up to 63 L/hour through 6 stages, for compact kitchens.
• ULTRA L-RO750A and L-RO750B: 7-stage RO + UV + Alkaline on an iron frame, 63 L/hour output and a 41.63 L tank for offices, schools and large families.

RO Water Purifier Price in Nepal: What Drives the Price

The difference between Rs. 24,225 and Rs. 84,150 comes down to capacity and features. At the lower end, a compact countertop unit like the RO500B gives multi-stage RO with an alkaline stage and a storage tank, without heating. Adding UV sterilisation, a hot-water heater, hot-and-cold dispensing, voice guidance or a TDS display moves the price up within the family-sized models.

The largest jump is capacity. The L-RO750A and L-RO750B produce around 63 litres per hour into a 41.63 L tank on an iron frame, compared with 11.8 L/hour on most family units, so they cost considerably more. Buy for your daily drinking and cooking volume rather than paying for capacity you will not use.

Installation, Filter Care and After-Sales

Mega Solar Energy delivers water purifiers across Nepal and can install them at your home or office: placing the unit, connecting the water supply where the model needs it, and running the first flush. Models with auto-flush rinse the RO membrane periodically to help it last longer.

Filters and the RO membrane wear out over time, and how fast depends on your water quality and daily use. Harder or muddier water means more frequent changes. Hot-water models also need a socket that can handle their heater load. Warranty terms are confirmed for each model at the time of purchase, and our team can help you source replacement filters.
