Thanks for reaching out with your question about the best water purifiers under 15000. As someone who has a great deal of experience with home appliances, I'd be more than happy to share my expertise with you.

In my opinion, the best water purifier under 15000 is the Kent Grand Plus. This purifier has been a mainstay in many Indian households for years and for good reason. It's a great purifier that combines quality and affordability. The Kent Grand Plus uses double purification technology that effectively removes impurities like bacteria, viruses, and chemicals from your drinking water. Additionally, the purifier has a large water storage capacity of 8 litres, so you won't have to refill it constantly. It's also easy to install and maintain.

Speaking of personal experience, I recently purchased the Kent Grand Plus for my own home and have been extremely satisfied with its performance. My family and I have been using it for several months now and have noticed a significant improvement in the taste and quality of our drinking water. Before purchasing this purifier, we used to rely on bottled water for drinking, but now we can enjoy clean and pure water straight from the tap. Overall, I highly recommend the Kent Grand Plus to anyone looking for a high-quality water purifier under 15000.
