The filters in Options 1 and 2 above are designed to filter normal "potable water" ie the water that you'd get from a mains tap in a harbour or a caravan park.
If you are worried about the quality of your source water - perhaps you're overseas - or just want to be as safe as possible, this ultrafiltration filter will help give you peace of mind. It filters your water down to 0.1 microns and is easy to fit and use.
If, for any reason, you are unsatisfied with your purchase from UK Water Filters you can return it in its original condition within 90 days for a refund. We'll even pay for return postage costs. Read more.
