Buying A Water Filter

I have recently installed a deep bore and submersible pump which is supplying plenty of water for our garden and house. Unfortunately the water has a very high iron content and my wife has a severe allergic reaction to this.

Can anyone recommend a reliable large capacity water filter supplier/installer and servicing agent in the Korat, Buri Ram area.

I understand that I may be looking at about Bt15,000 for a good quality large volume unit suitable for showers, laundry, washing up etc in the house. Any comments on price and recommendations on capacity would be appreciated.

Thanks,

Bicko
