I am sure you can use them multiple times ... BUT ... most plastics do leach ... very slowly ... up to you what you use ... but plastic does accumulate, slowly ... what it does, long term, is uncertain ... but increases in most horrid things is due to chemicals we get from food processing and packaging, and atmospheric pollution ...
I'd rather avoid any unnecessary risks ... and especially where kids are concerned.
It's easy enough to carry some glass bottles and refill from taps, daily, for drinking, ice cubes etc.
Chaque un son gout ...
I was prompted to make further comment to this post that I started after reading a lot of comments on this and other posts in relation to the perception of water filters.
I’m sure someone will correct me if I’m wrong but from all the trawling round caravan dealers and on-line, all of the filters I’ve seen are either sediment filters (i.e. remove any big bits) or carbon filters (remove any taste/odour). There doesn’t seem to be any advertised for caravanning which remove bacteria.
Filters do not remove the requirement for cleaning and sterilizing the on-board water system and neither sediment nor carbon filters will remove the requirement for some form of chemical treatment to keep the water in the tank disinfected. Indeed the use of chemical disinfectants is probably the main reason for using a carbon filter in the first place!
If you were to use a proper bacteria filter to filter the water prior to it entering the on-board water tank then no bacteria will enter the on-board water system so as long as you keep the on-board system clean you don’t need the additional chemical disinfectants, so no smell/odour issues and you also have clean, safe drinking water “on tap” so no need for trailing Vin Blanc’s 10 year old water bottles off to the nearest standpipe.
And just couple of final points which actually relates to another post completely but I think are worth saying…
Filters will block after a period of time. That is not because they have broken. In fact it is probably because they have done their job properly.
If your filter blocks and you simply remove it, then whatever blocked it will now get through to your tap/shower.
Filters, even if they are not blocked shouldn’t be left unchanged indefinitely. Bacteria can grow on the filter media which creates a situation where the filter can be creating the very issue it is intended to prevent.
Before giving up on water filters as a bad job it’s maybe considering what you might want your filter to actually do.

But the water is from a potable, treated water supply. I still cannot see why it needs filtering.

It doesn't, it's just another way of screwing you and others out of their hard earned cash.
In the early days of caravanning across the channel, fitering the water was probably a good idea but these days, water will be perfectly OK on reputable camping sites.

Most of the bacteria in the water system gets in when we stop using the caravan, air gets into the system along with airborne bacteria.
If you use bacteria filter to filter the water prior to it entering the on-board water pipework then the bacteria already present stays there, however the chlorine in the water will do its best to get rid of it.

Of course the biggest 'screwer of hard earned cash' is buying bottled water ... it's free from a tap!
I buy a 5lt and a 2 litre bottle of water from supermarket at the start of the season (and water their flowers with it), then keep the empty bottles for filling at the site tap, 5lt for cooking and coffee/tea etc and the 2lt for in the fridge

Worth checking the triangle labeling system on the bottles you use ... many are designed for single use only as they 'leach' plastic derivatives. We do the same, but always use glass bottles ... those 'Corona' top type ... coloured glass ... 'cheap as ...', in french supermarkets ...
