Help me with a 3M water dispenser please!

I am 42 and 3 months pregnant. This was unexpected as i thought i could never be carrying a child at this age. I am also a fulltime homemaker, married for 15 years and we have an 8-year old school-going daughter. Financial wise is we do have loans to pay but we are still able to get by. No savings managed faithfully yet though. We are trying to start for the new addition to the family.

Its just that we dont own a thermos flask and each time we boil water in the kettle to drink or to fill up the fridge bottles. However i do heard of stories of RO water and other water dispensing companies saying that no matter how boiled water is, its still not 100% clean (?)

I would love to own this 3M water dispenser. But its so expensive i dont think i can pay that lump sum to buy. Last i checked 3M has an offer of $1488 but that was last October. Now its $1888.

I would greatly appreciate any amount you may wish to help with, just hope i could get one before my due date in August. It would be a perfect gift for me and baby! And for my family too!

Thank you!
