Answer
Hello Prashant,

1. Is electricity required for the Water Purifiers your links showed? I do not know. But if they need power, power could come from a battery, if it is big enough.

2. If they are electrical, and commands are normally given by throwing a switch, yes remote control could be used.

3. As you can see from the above, I don't know anything about preferences between electrical and non electrical water purifier machines.

Expertise

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.

Experience

I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.
