Back up portable water filter

I am thinking about some kind of portable water filter should I a) run out of bottled water b) want to reduce waste and use local water but concerned about purity and taste. I have thought of something as basic as a Brita jug water filter more for taste than purifying.

Do you have a back up water filter, what type and brand?

Re: Back up portable water filter

We use a Pur pitcher, similar to Brita.

We just looked for a size/shape that would fit usefully into one of our fridges so we could have cold water available most of the time... otherwise the pitchers seem to be pretty standard.

Re: Back up portable water filter

Install an NSF 53-rated water filter system on your tank. Less than $50. Ditch the bottles.


As for emergency safety, chlorination (~ 5 ppm) will do more than any filter. Then pour it through the Brita to remove the chlorine. They are very good at that.

Re: Back up portable water filter

Expensive but VERY good. You'll never buy bottled water again and removes all tank taste. Even old water.
I've had one on every boat I've owned, my house, my office, run the icemakers thru it etc. Filters last about a year or more. $100 each.

Re: Back up portable water filter

We have a Seagull too, came with the boat, expensive, but will last decades. The cartridge will last a full timer a year or longer.

For Gods sake, donít do bottled water, it really is, well wrong.

Re: Back up portable water filter

I have always been unable to see the difference between a Seagull filter and other ceramic filters such as the AquaCera CeraMetix or the Doulton Ultracarb. They seem to be identical to me, but the Seagull is 4x the cost upfront and 2x the cost for cartridges.

The only difference I see listed in the specs is the Seagull alone claims to remove viruses. I have never believed that claim. If it were true, I can see how it could justify the additional cost.

I used the Doulton Ceramic filter on my last boat. I was planning to install the AquaCera on my current boat.

Re: Back up portable water filter

We made a water filtration system that we can hook up to any dock water in Mexico. It removes sediment and purifies with the UV. It doesn't, however, remove any heavy metals if present. The UV requires 110v.
Our tank water used for cooking, drinking, and ice cubes also goes through the Seagull filter at the sink.

Re: Back up portable water filter

I use a similar set up to Sailor647, just not permanently attached. Whenever I fill up my tanks, I always use a two-stage filter system, attached to the shore-water hose going in and a short 3-4 foot hose coming out (also on Amazon). System like this one:

https://www.amazon.com/Beech-Lane-Ex...ll-spons&psc=1

For $60, we have all-use water in our tanks at all times. With a 5 micron primary and 0.5 micron secondary filter, it's not quite the water from our watermaker, but is very good.

Re: Back up portable water filter

I just bought a Grayl Filter bottle. I have yet to use it, but friends have been happy using it for travel and backpacking. Its a very simple plunger arrangement thats light weight and perfect for getting safe drinking water from questionable sources. Not for seawater, of course. Only reverse osmosis or distillation can do that.

We do similar. I mentioned the Pur filter before for handy drinking water...

But we also fill our tanks with filtered water two, first a dual-gradient 25/1 micron filter, then a .5 micron carbon filter.

We even use the 25/1 micron filter for our dockside water supply. Can't use the .5 micron filter on that, though, because it affect water pressure too much.
