Frequently Asked Questions
Everything about Water Ka Doctor, maintenance, orders and delivery.
Product & technology
Its 0.1-micron hollow-fibre membrane removes 99.9999% of bacteria and pathogens, parasites and cysts, micro- and nano-plastics and all suspended solids such as mud, rust and silt.
No. It keeps dissolved minerals and does not decrease TDS, so it is not meant for salty or brackish water with high TDS. For high-TDS water you need reverse osmosis or another source — see our TDS guide.
No. It works on normal tap pressure or by gravity from a raised bucket, delivering up to 60 litres per hour — perfect during load-shedding.
ERM (Esoteric Resistive Membrane) fibres have an anti-microbial compound built into the membrane itself. Microbes that touch the surface are killed and washed away, so the membrane resists bio-fouling and nothing leaches into your water.
Yes. PAKVITAE’s purifier quality has been tested and certified by NUST, SGS and PCRWR.
Use & maintenance
Two years or 10,000 litres, whichever comes first — enough drinking water for a family of five.
Use the supplied syringe to backwash: push clean water backwards through the outlet to flush dirt out of the fibres. It takes under a minute; do it whenever flow slows or weekly with muddy water.
It is washable through backwash throughout its life. After 2 years or 10,000 litres the purifier should be replaced.
Yes, as long as the water is sweet (low TDS) and not chemically or industrially contaminated. Very muddy water should be allowed to settle first.
