"I’ve been using the *Proven RO* for [2 months] and I’m genuinely impressed. Our borewell water has high TDS ∼750, but this purifier brings it down to ∼90. The water tastes sweet and clean with zero smell.*What makes it great:*- *Purification is top-notch*: RO+UV+UF+TDS control handles our hard water perfectly. No more white deposits in steel utensils.- *Smart features that help*: Auto shut-off saves power, and the filter change alert is super accurate. The storage..."

"We bought the Proven Swift to replace an ageing purifier at home. There is a clear difference in how light and fresh the water tastes now."
"We have a family of four, so we wanted a reliable purifier and chose the Proven Swift. The copper feature was the main reason we picked this model. The alkaline water feels smoother and easier to drink. Glad we made the switch."
"After comparing a few models, we finally chose the Proven Nexon. Earlier our water tasted flat; the TDS adjustment has fixed that. The mineral enhancement is a clear upgrade over our old basic RO. No complaints at all till now."
"Really happy with this purchase. The quality exceeded my expectations and delivery was fast. Proven has gained a loyal customer!"
"Perfect in every way. Build quality, finish, and performance — all top tier. Installation team was professional and on time."
"The alkaline option is a welcome plus for daily drinking. The purification is fine, yet a few small things about the design and handling did not quite match what I had in mind."
"Received within 2 days. Product looks premium and works as expected. Happy with the purchase overall."
"It is good that essential minerals are retained instead of being stripped away."
"Shifted to a new flat and bought the Proven Alfa for the kitchen. The difference on our hard water is very noticeable. A few weeks in and it has been completely trouble-free. Glad we made the switch."
"Our building water needed proper purification, so we got the Proven Eleven. We never run short of water thanks to the 12L storage. It looks modern and tidy in the kitchen. Storing copper water the traditional way was a hassle; this does it automatically. Does exactly what we needed it to."
"After comparing a few models, we finally chose the Proven Alfa. The RO, UV and UF combination handles our water quality nicely."
"We have a family of four, so we wanted a reliable purifier and chose the Proven Swift. We never run short of water thanks to the 12L storage. Storing copper water the traditional way was a hassle; this does it automatically."
"It does purify well and the taste has improved, though I might consider a different variant next time for our needs."
"This is the first proper water purifier for our new home, and we went with the Proven Pixer. Knowing the water passes through several stages makes us more confident. No leaks, no fuss — it just works every day. Would recommend it to other families."
"We have a family of four, so we wanted a reliable purifier and chose the Proven Pixer. The added minerals make the water feel better than plain RO water. Compared with bigger brands, this was better value for the specs. A slightly longer warranty would have made it perfect."
"The feature set is genuinely useful, though the outer finish could feel a little more premium."
"Decided on the Proven Pixer for our kitchen and have been using it daily. The alkaline option is a welcome plus for daily drinking. A few weeks in and it has been completely trouble-free. Would recommend it to other families."
"Received within 2 days. Product looks premium and works as expected. Happy with the purchase overall."
"This is the first proper water purifier for our new home, and we went with the Proven Pixer. We chose it mainly for the alkaline water, and it has not disappointed."
"Wanted to upgrade from a basic model, so we went for the Proven Pixer. We specifically wanted the copper option, and the copper water has become a daily habit."
"After comparing a few models, we finally chose the Proven Alfa. Knowing the water passes through several stages makes us more confident. The copper-infused water is a nice touch that the whole family enjoys."
"Our old purifier had started giving up, so we switched to the Proven Nexon. The alkaline water feels smoother and easier to drink. It looks modern and tidy in the kitchen. Filling speed could be a touch faster, but it is a minor thing."
"This is the first proper water purifier for our new home, and we went with the Proven Pixer. The RO, UV and UF combination handles our water quality nicely."
"We bought the Proven Jupiter to replace an ageing purifier at home. Being able to balance the TDS makes a real difference to the taste."
