Inflatable Pool With Filter

my inflatable pool does not come with a filter, I can buy one separately and I will be able to connect in some way?

I do not want to fill and empty every few days, so I love to buy a filter high, but the pool should have a filter built in that can not be found anywhere?

if you do not come with one that does not need it
