Best Water Purifiers

I’m looking for something that really works well. A purifier, not just a filter. Something .2 micron (or smaller) and with a built-in way to automatically chemically treat the water (iodine/chlorine etc). There are several on the market and I’m looking for other peoples experiences and opinions. Something that could be used full time for weeks at a time on long trips where your only water source is creeks and lakes and in countries with questionable tap water.

I am about to travel to 3rd world countries where water mostly contaminated.
Do you know where i can buy a personal water filter? or something that I can get the water clean immediately before drinking? I don’t have enough time to buy online….so Home depot? sears? anyone can give me what you got please?
thanks
Answer(1), Yes, I know bottled water available everywhere, but I have good reasons to look for personal or portable water filter.

I do normal body work out of my 2 car garage. I use tools such as a 6″ D/A Sander, Inline Board Sander, 1/2″ Drive Impact Wrench, Sand Blaster, DeVilbiss HVLP Spray Gun, and a Media Spot Blaster. I currently have a Campbell Hausfeild 60 Gallon Compressor, and have terrible problems with water in my lines. I have a water trap that does absolutely nothing. I am now getting a spare 10 gallon tank for the air/water to travel to first, then am going to get either one of those Toilet Paper water filters, or am looking at a DeVilbiss Desiccant Filter/Compressed Air Dryer. Any opinions on which would work best? The TP Filter is about 80 bucks, and the air dryer will be about 250. Which is better or are there any first hand users?
I will be moving my 2nd tank away from the compressor/tank when I get one. Along with the filter or dryer. I just need to know which one to get.
And I currently drain the water from the main tank about every 30 minutes of use.
