Water Purification

Water Purification

There’s much written about water purification on the Internet.  Fortunately for those of us   living in and around Portland there is little to worry about regarding our water supply.  Portland water comes from the bull run watershed which is one of the cleanest sources of municipal water in the country. However there are a few caveats.  First of all if you live in Wilsonville, outer Tigard and Sherwood chances are you’re water comes from the Tualatin River . Because of farm and industrial runoff I highly recommend a whole house or at least drinking water purifier.  Also if you live in an older house whose pipes or line from the street have not been updated, then I recommend a water purifier on the faucet you drink from.  Also most water is chlorinated which can be toxic over time and is harmful to hair and scalp (dandruff and spending more on hair treatment, conditioner and shampoo), so a showerhead chlorine purifier is recommended.

Types of water filters:


Pros: inexpensive and no installation needed. Water purification does not need to be: not super households require more than a couple of gallons of filtered water a day filter life is relatively short period

Price: $20-$40 plus $40 $200 per year in replacement filters.

Faucet mounted

Pros: easy installation and quick switching between filtered and unfiltered water.

Cons: slow flow rate.  Can’t be used with most pull down or sprayed faucets.

Price: $15-$35 plus $30 to $100 per year in replacement filters.


Pros: good for filtering large volume of water without plumbing modification.

Cons:  creates clutter on the countertops and can’t be used with most spray or pull down faucets.  Some models have fairly low flow rates.

Price: $50-$300, plus $50-$100 per year in replacement filters.

Under sink

Pros: filters large volume of water, doesn’t clutter the countertop and you don’t have to modify faucet.

Cons: take up cabinet space requires plumbing modification as well as a hole in the sink or countertop for the dispenser.

Price $100-$550, plus $50 $250 per year in replacement filters.

Reverse Osmosis

Pros: removes the widest range of contaminants, including arsenic.

Cons: requires plumbing modifications and periodic sanitizing with bleach.  Latest three to 5 gallons of water for every gallon of filtered.  Some are slow.  Takes up cabinet space.

Price: $150-$900, plus $100-$200 per year in filters or pro-servicing.

Pros: Removes everything but H2O.
Cons: can be time consuming
Price: $300-$1900, plus $38 per year for carbon filters
