Hey everyone! I'm trying to find a decent 2-4 stage water filtration system. Does anyone have any suggestions?



Edited 1 times.

I've seen ads for Zero Water systems : [www.zerowater.com]. Impressive results; no plumbing required. Britta makes similiar filters for less money, but they don't catch as much impurities. That's the cheaper, quick and easy way. Neither one is automatic; the pitcher must be mannualy refilled.

Then there are all kinds of undersink plumbed filter systems. More $$$$ and time to install, change filters, and hope they don't discontinue your filter cartridge next year.

I finally tried the PUR screw-on faucet adaptor, and have used it ever since with good results.

It works for me.

couple of these in series

plus

cartridges suitable for your purpose

typically

1- course

2- fine

3- activated carbon

Much depends on the condition of your water and what you want to achieve. So what do you want to achieve?

Most reverse osmosis systems are 5 stage.

Reverse osmosis will remove just about anything that your water delivers; check out the specs on RO. A few dollars more, but inclusive.

RO systems are maintenance NIGHTMARES if maintained as per specification.

Among requirements is an ANNUAL cleaning/disinfection via a LABORIOUS procedure.

RO water should NOT be used for ice making in a fridge.

IMO: unless you have a special case situation forget RO.

"... unless you have a special case situation forget RO..."

Without testing, one cannot know. How many HO's test yearly (minimum) for pathogens, bacteria, lead, nitrates, etc. RO assures peace of mind knowing that it will eliminate ~90+% of 'stuff' in water when properly maintained. UV makes a good preceder to RO.

RO is required for home dialysis equipment.

HOWEVER

for general purposes I would:

1- 50 micron dirt & sediment . change quarterly

2- 2 micron 'final' prefilter . change semi to annually

3- activated carbon . change every 6-9 month

4- enjoy the great water

And WHY not? I have been using it for my undercounter icemaker for the past 20+ years. Using it makes "clear" cubes. How would you separate the icemaker from the water dispenser in a fridge since they have a common feed.

That looks like as much, or more, work than an RO system.

its not the work of installation

(an RO system requires all the above + the RO membrane assbly + the storage tank + the backwash indirect drain connection)

its the ongoing maintenance

no annual cleaning/disinfection required, merely change the filter cartridges as required/specified

Note that reverse osmosis systems waste a lot of water as well as all brands of r.o. membranes have a limited shelf life .... "buyer beware."

RO systems for years now have incorporated "automatic shut-off valves" that minimize water waste.

I'm not a water expert and so please don't accept my words as facts when searching for what is the "the best" filtration system (it really mostly depends on your source of water and the quality of the filtration system) ...... automatic shutoff valves or not .... a 4 to 1 ratio is probably about as "tight" of a water waste as possible with an r.o. system which to me means it takes 4 gallons of water to produce 1 gallon of r.o. water. That's 3 gallons of water wasted down the drain.
