In the realm of water purification, non-electric water purifiers (gravity-based water purifiers) stand out as cost-effective, portable marvels that demand minimal maintenance. Often mistaken for being merely affordable, these purifiers are, in fact, a powerhouse of efficiency. Renowned as the unsung heroes of water filtration, they cater to those with municipal water supplies or areas blessed with low Total Dissolved Solids (TDS) levels.
Look no further if you’re in search of the optimal solution, as we present to you a curated list of India’s top gravity-based water purifiers, equally celebrated as the best UF (ultrafiltration) water purifiers. Uncover the essence of pure water without reliance on electricity as we guide you through the best options tailored to your needs. Discover the seamless blend of affordability, portability, and performance in the realm of water purification, ensuring a clean and healthy drinking experience.
What is Gravity-Based Water Purification?
In essence, a non-electric water purifier is a device that operates without electricity, relying solely on gravity for its filtration process. The absence of a pump is a key characteristic, with the sediment filter, carbon filter, and microfilter fiber UF membrane all working seamlessly in a gravity-based system.
For those with soft water or a TDS level below 300, opting for a UF-filtered non-gravity water purifier is a budget-friendly choice. These non-electric water purifiers, which fall under the gravity-based category, utilize a fiber UF membrane to effectively block bacteria and cysts, ensuring water purity. The pore size of the UF water purifier ranges from 0.002 to 0.5, effectively preventing the passage of bacteria (0.5–20 um) and viruses (0.03–1 um), thereby purifying the water.
Crucially, the water purifier incorporates a vertical arrangement of filters, such as sediment filters, carbon filters, and microfilters. This strategic stacking eliminates impurities and thoroughly cleanses the water.
Key Insight: A gravity-based water filter is commonly referred to as a non-electric water purifier, emphasizing the shared principle of operating without electricity. This means that non-electric and gravity water purifiers are synonymous. Additionally, a UF water purifier is interchangeably known as a non-electric or gravity purifier, although it can also be used in conjunction with an electric water purifier.
