would converting to saltwater pool help allergies, sneezing, congestions, triggered by the Chemicals?

Answer 1

Yes, on Extreme Home Makeover they put a saltwater pool in a house for a child who had severe allergies and even needed her house hepa filtered. Apparently converting over is easier than ever before too.

Answer 2

I would think so - just think about that saltwater might harm your installations more than the chemicals. Check that before.

A better solution, provided you have the space: There are so-called natural pools with one half of the surface being free for swimming and the rest being a biological water-renewal part with plants and stones. I don't know their name in English, here in Switzerland (and surrounding countries) they are quite popular for new pools.

The website suggested is in German, there is a link for French - anyway I'm quite sure the company would answer any mails in English if requested.

Answer 3

There's another option besides salt. It's called Pristine Blue. I used to work out in a Pristine Blue pool. It's got zero chlorine and it was wonderful. I work out in a pool that's mixed salt and chlorine now and it's eating my bathing suits and I stink of bleach unless I scrub myself with Spa Wisdom Salt Scrub (nothing else works).
