New branding+domain and UK +Irish market survey

We need a specialist to check the UK and Irish Market for water filtration(domestic market)
We want to specialize in reverse osmosis under the kitchen sink
Giving people a lot of freshwater without going to the store to buy that bottled water
our provider of filters is https://aquaphor.com/
https://aquaphor.com/reverse-osmosis/ro-102s our product
https://aquaphor.com/replacement-under-counter-filters our replacement cartridges
we want to start the sales of the filtration in Ireland but don't know where to start and what name to get
We need to choose the domain name first
it has to be super short and customers will have to search for this name most when looking for filtered water and no more 4bottled water
Please assist us with the ideas for the domain name and ideas about branding
we also need to register names fro the social platforms
So we can look into the registration below afterward

• DNS provider i.e Registrar for your preferred domain
• Email service provider i.e Exchange 365 e.t.c
• ActiveCampaign
• Calendly
• Facebook
• Instagram
