Do you know that WHO and BIS stipulate that water with TDS levels less than 500ppm is fit for human consumption?

Therefore, it does not require RO purification unless your water source is near industrial locations. Under circumstances where the TDS levels in water are 250ppm or lower, you can comfortably rely on gravity-based water purifiers.

Best non electric water filters

This article lists excellent non-electric gravity water purifiers and clears all doubts about such appliances.

1. Kent Gold Optima Gravity Water Purifier

KENT Gold Optima Gravity

The Kent Gold Optima Gravity water purifier is as close as possible to an RO water purifier because it uses a high-quality UF membrane to purify water. Though it cannot handle TDS, it traps contaminants as small as 0.1 microns.

So, if your water source is RO-purified municipal water with TDS levels less than 250ppm, it should be ideal. Besides UF, it has sediment and activated carbon filters to remove foul odor and enhance the water’s taste.

The sediment filter and carbon filters prove helpful in enhancing water quality. However, these filter cartridges and the UF membrane require frequent replacement, making it an expensive appliance.

This appliance conforms to international water purification standards. It delivers excellent performance, but the 5L pure water-holding capacity can be a concern, especially for large families.

The UF membrane can purify up to 4000 liters of water. But replacing it every six months is essential. Besides, cleaning the filter is necessary because the contaminants can block the pores and affect the appliance’s filtering ability.
