Where do impurities in water come from?

Singapore holds one of the highest standards of clean water, but that does not mean the water that flows into our homes are completely free from sediments.

Water tanks and external piping

Over time, dust and sand particles have a way of settling into every nook and cranny, including water tanks above HDB flats and external water piping.

Live in a landed house?

Landed houses are not exempt either, especially those located close to the sea.

If you have lived in an island resort, you may have on occasion, noticed fine sand particles while soaking in your tub.

The solution?
Use a pre-filter.

Pre-filters are easily installed just after your water meter. Water rushes through its mesh filters and sediments are trapped in its body.

Pre-filters offer a layer of protection for your water appliance. E.g. water heaters, washing machines, faucets.

High precision, food-grade stainless steel filter mesh

Filter mesh removes large impurities, sediments and rust effectively. Water quality sees an overall improvement and this extends the service life of domestic water heaters and other water-related appliances.

Where can I install my pre filter?

Fit your pre-filter on any horizontal pipe after the water meter. The pre-filter is usually installed outside the house.

Clearance from floor to the bottom of filter mustbe at least 40mm.

Fix the pre-filter after the water meter, not before it.

How do I maintain my pre filter?

It is easy to maintain a pre-filter. There are no service packages involved and you can easily flush the filter on your own with a twist valve.

How often must I change my filter?

The pre filter does not need to be changed, it can last several years. However, it is recommended that owners flush out the sediments once every three to four months.

Tip: place pail below the filter when flushing. You may use the flushed water for washing the floor or watering plants.

How effective is the pre filter?

Water quality varies in different areas of Singapore and those living close to the sea can expect more sand sediments. The pre filter filters out particles larger than 100 microns (𝜇m).

Will pre filters affect water pressure?

Pre filters will not reduce your water pressure. They are suitable for both HDB and private housing.
