I have not using it for many many yrs. After the UV easily get burn and the casing burst when pressure high. Flood my house overnight. 

Still below my sink. Time to throw it away.

3M DWS 1000 deluxe drinking filter has been tested and verified by NSF. 3M is a well known brand and a big company, this filter is made in USA. Here is how good the filter is




This is their outdoor filter AP902, more compact and durable than membrane filters

How long it will last and how well it can filter are 2 different thing. IMO, the later is more important than durability.

We are lucky than in Malaysia we have plenty of land and most people can afford to live in landed properties. For people like me who live in apartments, no way I can install backwash filters or the 'rocket' type of outdoor filter.

But with 3M outdoor filter, it solves the problem because it is compact enough to be mounted on walls and hassle free with no maintenance (washing, etc).

Sometimes I wonder about the backwash filters, why so frequent need to backwash? First thought would be because the filter inside is not high performance and cant hold much dirt.

Also, keep washing and flushing, it will reduce performance? Just imagine the clothes, u keep washing the fabric also gets thinner and lubang gets bigger...no?

hi, just a dumb question. For condo, where to install the outdoor water filter (i am refering to your 3M outdoor+indoor package) and do i need special piping for it ? and same for the indoor water filter do i need special piping for it or i can just install the indoor water filter anytime after renovation is completed? How abt the maintenance, how long to change the outdoor and indoor filter and whether we need technicians to come and provide the service, many thanks and sorry if you've answered these questions previously, coz i hd no time to flip page by page 

Most membrane filters like Hydro1 are about the same, 0.01 micron filtration and optional automatic flushing. Most membrane filters will claim that they are durable, would not reduce water pressure and etc but in fact most membrane filters could not withstand high pressure and is quite fragile. No doubt filtration wise, membrane is the best but due to the super fine filtration of 0.01 micron, it will reduce water pressure a lot. The question is, is 0.01 micron filtration required for washing clothes, showering and etc? With the fine filtration, filters get clogged easily and require regular flushing (everyday). Here is a demo of it

try avoid too expensive outdoor filter, ppl can steal it.
the outdoor filter mainly is to filter make sure the water is not contaminated and not yellowish (Use for bath, washing machine etc)

And you got to need a good water filter indoor for ur drinking just like espring, if you always cook ur water before drinking it then can consider 3M AP which is cheaper.

Just want to share with you on point of entry membrane filter. I am using one since 2006 and its turbidity is measured at 0.1NTU which is as clean as the bottled water. No filter change and you spend 30 sec for back flushing once a week. Visit website www.ittellwater.com for more info.

Sand Filter normally need to be change 3-5years, Membrane Filter normally 1years. So you trying to tell us you have been using for 7years without changing yours? Seriously, you better contact the person and change for you right away.
