Are Gravity Based or Non Electric Water Purifiers safe to use?

Absolutely, Yes. The non electric water purifier offers chemical-free filtration of the contaminated water. Even with different levels of filtration, it can remove all the impurities present in the water, including mud, sand, dust, and other coarse particles. It also eliminates bacteria, viruses, protozoa, parasites, etc. But, these water purifiers are capable only to purify the water with a low TDS level (>300 ppm). So, if in your area, the TDS level in water is above 300 ppm, a gravity based water purifier is not an ideal option.

What is Ultra Filtration?

Ultrafiltration is a membrane filtration process that uses hydrostatic pressure to force water through a semipermeable membrane. The process can remove essentially all the colloidal particles (0.01 to 1.0 microns) from water and some of the largest dissolved contaminants.

When should you change the UF membrane of non electric water purifiers?

UF membrane must be changed once every year.

How can you clean the Gravity Based Water Purifier?

For thorough cleaning of the water purifier, you must first disassemble the parts of it. Then wash them using the liquid soap and running water. You must follow the procedure at least twice a month. Assemble the parts again. After cleaning, discard the first batch of water to flush out the remaining impurities from it.
