Our top pick for filtered drinking water at home is the Aquaphor Crystal Eco under-sink filter at RM550 on Shopee Malaysia (price checked 31 October 2026): it gives you a dedicated filtered tap without a big machine. For the whole house, the 3M AP902 at RM1,486.30 is the one we would look at first, and the cheapest way to try a filter is a two-stage cartridge unit from RM15.21.
This guide is eight water filters, not water purifiers: a filter takes out particles, chlorine and bad taste, while a purifier machine (reverse osmosis or boiling) goes further. If you want that, read our best water purifiers in Malaysia guide instead. We checked every listing below on Shopee Malaysia on 31 October 2026; we did not buy or test any of them.

Best for drinking water at the kitchen tap: Aquaphor Crystal Eco
If the question is "what should I drink from?", an under-sink unit is the tidiest answer, and the Aquaphor Crystal Eco is the one we would start with. It sits out of sight, filters the water at its own small tap, and the slim body leaves room for the bin and cleaning supplies. At RM550 on Shopee Malaysia (checked 31 October 2026) it costs a fraction of the whole-house units below. Skip it if you rent and cannot touch the plumbing: it needs fitting, and the seller offers an installation service you should ask about before paying.
Under-sink cartridge filter, silver-impregnated cartridges, slim body
Our pick for filtered drinking and cooking water at one tap, at a price most households can justify.
- Slim under-sink unit that gives you filtered water at a dedicated tap
- Cartridges are silver-impregnated to limit bacteria growth inside the filter
- Needs a spot under the sink, a cut in the worktop for the tap and a bit of plumbing, so budget for installation
Best for the whole house: 3M Outdoor Water Filter AP902
The 3M AP902 filters the water before it reaches any tap, shower or washing machine, which is a different job from a drinking filter: it is aimed at cleaner water across the home, not just one glass. The stainless steel housing means no rust, and the large ports suit a mains line. At RM1,486.30 on Shopee Malaysia (checked 31 October 2026) it is the sensible big spend for a landed house with muddy or smelly water. For a flat, with no outdoor mains line to fit it on, it is the wrong product.
Outdoor whole-house filter, stainless steel housing, large ports
A proven whole-house option from a brand most Malaysians already know.
- Stainless steel housing, so no rust to worry about on an outdoor mains line
- Large ports that suit a whole-house install
- Treats the whole house but is not a drinking-water polisher, so you may still want a tap filter inside
Best for a tough outdoor install: Waterco Micron W250
Waterco is better known for pool equipment, and the Micron W250 shows it: a corrosion and UV resistant outer shell made to live outside, and an inner layer rated for 700kPa of pressure. It costs RM1,480 on Shopee Malaysia (checked 31 October 2026), within a few ringgit of the 3M AP902, so the choice is brand and fit rather than price. The listings we found are from pool and water-filter dealers, so ask the seller what is in the box and whether the filter media is included before you pay.
Outdoor top-mount master filter, fibreglass-wound inner layer, rated for 700kPa
Built for the weather and the mains pressure, at nearly the same price as the 3M.
- Corrosion and UV resistant outer shell, built to sit outdoors
- Fibreglass-wound inner layer rated for 700kPa of pressure
- Needs a proper outdoor install and the cartridge or media will need replacing over time
Best for a stainless steel outdoor filter: Waterborn Stainless Steel W-300Z
The Waterborn W-300Z is the premium end of the whole-house group: a stainless steel master filter that is sturdy, needs little upkeep and is good at taking out odours. At RM1,899 on Shopee Malaysia (checked 31 October 2026) it costs about RM400 more than the 3M or Waterco units above, and what you are paying for is the build rather than a cleaner glass of water. If budget is tight, buy one of the two cheaper outdoor units instead.
Outdoor stainless steel master filter, Australian-made
The best-built outdoor filter on the list, and the dearest.
- Stainless steel body that looks after itself outdoors
- Low maintenance and good at taking out odours
- The most expensive pick here, and it still needs a plumber to fit
Best for a cheap tap-mounted filter: Xiaomi Mi Mijia Faucet Filter
This is the easy yes for renters: the Xiaomi Mijia Faucet Filter screws onto the end of the kitchen tap in minutes and the water comes out through a carbon filter. It costs RM78.90 on Shopee Malaysia (checked 31 October 2026) for the current Faucet Purifier 2 listing we found, which is a newer version than the one first reviewed in this guide. It improves taste and smell, and that is all: a tap filter does not make water of doubtful quality safe to drink, and the filter element must be replaced on schedule.
Tap-mounted carbon filter, three water outflow modes, fits most standard taps
The lowest-effort upgrade for a rented flat.
- Screws onto the tap yourself in minutes, no plumber
- Three water outflow modes
- The filter element has to be replaced regularly, and a carbon tap filter will not make unsafe water safe
Best for the lowest price: Double Stage Domestic Filter
A two-stage cartridge filter, with a PP sediment stage for particles and a CTO carbon stage for chlorine, taste and odour. Listings run from about RM15 to RM90, and the one we picked is RM15.21 on Shopee Malaysia (checked 31 October 2026) from a seller with 54 sales and a 4.8 rating. It is a generic, unbranded unit, so do not expect a brand warranty. It is a way to try filtered water cheaply, not a final answer.
Two-stage cartridge filter: PP sediment stage plus CTO carbon stage
A cheap trial of a sediment and carbon filter.
- The cheapest way into filtered water on this list
- Easy to install and easy to maintain
- Basic sediment and carbon stages only, with some buyers reporting minor leaks at the fittings
Best for hiking and camping: Sawyer Micro Squeeze Mini
The Sawyer Mini is for the trail, not the kitchen. It is a 0.1 micron hollow-fibre filter that threads onto a squeeze pouch or bottle, small and light enough to forget in a daypack. At RM55 on Shopee Malaysia (checked 31 October 2026) it is the cheapest piece of outdoor safety gear on this list. It handles bacteria and protozoa from streams, but not viruses or dissolved chemicals, so it is no use on polluted water.
Hollow-fibre squeeze filter, 0.1 micron, compact and light
Cheap, light and sensible backup for hikers.
- Compact and light enough to carry in a daypack
- Drink straight from a stream or squeeze into a bottle
- Removes bacteria and protozoa but not viruses or chemicals, so not for polluted or unknown sources
Best for emergencies and travel: LifeStraw Personal Portable
The LifeStraw Personal is a straw: put it in the water and drink. It has no parts to assemble and a very long shelf life, which is why it keeps appearing in flood kits and car boots. It costs RM106 on Shopee Malaysia (checked 31 October 2026). The limits are the same as the Sawyer: it filters bacteria and protozoa, not viruses or chemicals, and you cannot store water with it. Buy it for floods and trips, not for the kitchen.
Straw-style hollow-fibre filter, no moving parts, long shelf life
The grab-and-go option for a flood kit or a trip.
- Unlimited shelf life and nothing to assemble
- Light, small and easy to rinse clean
- Straw only: no storage, and it will not remove viruses or chemicals
How We Chose
We checked each pick on Shopee Malaysia on 31 October 2026 for a live listing at a visible price, with a real seller, and picked the lowest sensible price rather than the dearest brand store. Nothing here was bought or tested by us. This guide dates from 2018, and we have dropped five picks that are no longer easy to buy in Malaysia: the Aquasana AQ-4000W-DVPI, VWA MMP Twin Filters, 3M Indoor CTM-01SE, Coway Genie P-07IU and the Alkaline Water Filter System K-3000. We found no Shopee listing for the complete unit of any of them (for the Coway Genie and the 3M indoor model, only replacement cartridges). Lazada buttons on some picks were kept from the earlier version of this guide and we could not re-check them, because Lazada blocks automated checks. Buy links are our affiliate links, and we may earn a commission at no extra cost to you.
How to Choose a Water Filter
Match the filter to the job
A tap filter or two-stage cartridge improves taste and smell. A whole-house unit protects pipes and appliances from sediment. A straw or squeeze filter is for streams and floods, never for your kitchen. Buy for the problem you actually have.
Check the cartridge before the price
Ask what the replacement cartridge costs and how often it needs changing. A cheap filter with an expensive or hard-to-find cartridge is not cheap, and an old cartridge can do more harm than none.
People Also Ask
Which one is better, Coway or Cuckoo?
Neither is a plain filter, so neither is in this list: both are Korean water purifier machines, usually sold with a service plan, and we did not find a clear Shopee listing for a complete unit we could stand behind. Choose by the service plan and the price of the filter changes rather than the logo, and compare them in our water purifier guide.
Do water filters remove chlorine?
Only some. Filters with an activated carbon stage, like the CTO stage in the two-stage unit and the carbon tap filter above, reduce chlorine and its taste and smell. A sediment filter only catches particles, and the straw and squeeze filters are made for bacteria and protozoa, not chlorine or other chemicals.
What is a reverse osmosis water filter?
Reverse osmosis (RO) pushes water through a very fine membrane under pressure to remove dissolved salts and many other contaminants. It needs a pump and usually power, wastes some water and needs more upkeep. None of the eight picks above is an RO unit, so see our water purifier guide if you want one.
Is there a downside to drinking filtered water?
Yes, if you do not look after the filter. A cartridge left in too long can grow bacteria and stop working. Some filters, especially RO, also strip minerals, and the cartridges are a running cost. Filtered water is a good habit, but only with the cartridge changed on time.
