Things to consider and which model to choose for you?

Each On-Tap water purifier come with its own compatible replacement filter, although there are a few models that are using a common replacement filters, just take note to get the correct replacement filters

All Philips On-Tap water purifier filters are rated for the following:
- Rated Flow Rate – The total volume of water that can be filtered which meet the product qualification standard. If the filter is rated as 150 litres, then it means the total volume of water on “filtered mode” that can filter and meet the specs given on product quality standards. After the 150 litres, the filter still serve its function, but the filtration water quality will start to degrade until it hits the recommended “Actual Water Flow Rate”, by which time, you should change the filter. E.g. if you want to maintain the 99.99% sterilization rate, or 99% chlorine removal rate, you’ll need to replace the filter after 150 litres;
- Actual Water Flow Rate (Life Span) – The amount of water being used or coming out of a fixture in a certain period of time, before you should change the filter. If you continue to use the filter, the amount of filtered impurities and bacteria accumulated within the filter may likely cause secondary pollution.
  
  For example:
  The Rated Flow Rate for the filter is rated as 150 litres, that means the filter will be able to filter 150 litres of raw water from your local water supply authorities, meeting the filtration specs as given for the particular filter. If you go beyond the 150 litres, the filter will start degrading and will not be as efficient when totally new.
  
  You can either replace the filter with a new one, which would give you the 100% filtration specs as given on official product page, OR, if you continue to use the filter, the filter will continue to degrade until you reach the Actual Water Flow Rate (Life Span) of the filter, say 1,000 litres, by this time, you MUST replace the filter, as it would had accumulate enough filtration impurities, if continue to use, it will cause secondary pollution.
The Suggested Life Span for each type of filter will also depends on the water quality coming from your local water authority. If there’s a burst pipe repair at your area, or your building maintenance just clean the water tank, try to drain the initial muddy water on “by-pass” mode on the on-tap purifier, instead of going through the filters.

Suggested Life Span are usually measured by the number of litres of filtered water a person consume per day. E.g. for a Rated Flow Rate of 300L, if a person’s daily consumption of filtered water is 3 litres, then the Suggested Life Span is 100 days.

Again, the above is assuming you are using filtered water for drinking only, if you are using it for washing vegetables, making teas etc, you may consume more filtered water than originally planned, and the Suggested Life Span will greatly reduced.
The On-Tap purifier operates in at least 2 modes – “Filtered Mode” where incoming tap water is filtered, and “By-Pass” mode, where tap water will be dispensed as it is, unfiltered. You may want to operate it in filtered mode for drinking or other intended purposes, while for other washing purposes, you may want to use it on “By-Pass” mode, otherwise it will be a waste on the filter.
Choosing the type of filter will depends on your household filtered water usage requirements:
- What kind of filtered water quality do you need, e.g.
  - To remove Chlorine and heavy metals only
  - To remove bacteria, germs, chlorine and heavy metals
- The number of people using filtered water, which will determine the total volume if “filtered water” requirements
- How you use filtered water, so that you can estimate what volume of rated flow rate of filtered water you need e.g.
  - you are washing veges, hands with chlorine removal water only, or
  - you want every usage to be bacteria free or chlorine and heavy metal free. or
  - you just want drinking water to be filtered
- For a single person, you may not require a filter with high Rated Flow Rate of, say 1,500 litres, if your usage is low, e.g. you only consume 3 litres of filtered water daily, while the 1,500L filter may last you 500 days, but prolonged accumulated impurities and bacteria in the filter over such a long period may cause secondary pollution if your usage is very low. It is more recommended for you to get a lower volume filter
- Recommended Filter Replacement – Philips recommend the filter to be replaced after used for over 90 days, or the lapsed the rated filtered volume.
- Any indicator built-in for changing / replacement of filters? – No, there are no indicator. But each filter have the recommended rated filtration capacity, and user need to estimate the volume of filtered water needed in the household, based on a single person’s consumption daily, and the number of people in the household. See picture below for Filter WP3911.

Sample calculation of filter requirements base on household headcounts and total water consumption

Compatible Faucets – These On-Tap Water purifiers are only suitable for the following faucets

Can you drink direct from these filtered water?

It will depends on your source of raw water, if your raw water is from your local town/city municipal water authority supplies, and that they have certified safe to drink from tap direct, then it would be safe to drink directly from. However, there could be isolated cases of contamination in your building’s piping system, e.g. rusting pipes, or water tank, you may need to check on that.

Different water filter removes different impurities in the raw water, according to the specs given on the respective product pages. It also depends on the water quality where you live, to decide what kind of filters you want to get.

Any Indicator on filter for changing of filter cartridge?

No, there is no indicator built-in. But there are different mechanism to monitor the lifespan and aging of filter inside:

a) for AWP3600 & AWP3611, there’s a manual dial filter replacement reminder on top of the main body, which you can set the month (nearest to half-month) when you last replaced the filter

b) for WP3811, AWP3876 and AWP3877, there’s an transparent opening on top of the filter, which you can lift the cover, and see the condition of filter inside,you can use the concise color code to remind you that the filter should be replaced when the filter is dark gray or reddish brown, depending on the degraded condition of the filter.
