Water Filtration Systems on Whidbey Island, WA
- Aeration systems are effective in areas with low amounts of contaminants, and will reduce iron, manganese and sulfur.
- Chlorine systems are appropriate for water containing aggressive iron bacteria and high levels of hardness and tannin.
- Ozone is a powerful technology for oxidizing and removing dissolved minerals, off-gassing sulfur, and eliminating chemicals.
- Oxygen systems are ideal for water high in minerals (esp. iron & manganese), bacteria, sulfur, hardness, chemicals, tannin, and arsenic.

Whidbey Water Filters
Oxidation Water Filtration Systems Whidbey Island WA
How do different water filtration systems stack up against each other and against the contaminants in your potable water? Whidbey Water Filters has compiled a convenient breakdown of different systems and their water purification capabilities. We recommend Whidbey Island WA homeowners compare and contrast different options before deciding on any one system (or combined filters) to treat their potable water. Here’s what you need to know.
Four Technologies
How do different water filtration systems stack up against each other and against the contaminants in your potable water? Whidbey Water Filters has compiled a convenient breakdown of different systems and their water purification capabilities. We recommend Whidbey Island WA homeowners compare and contrast different options before deciding on any one system (or combined filters) to treat their potable water. Here’s what you need to know.
Cost Range
In order of water purification cost, compressed air is the least expensive and the least effective, while chemical injection is a mid-range price and treats most things. Ozone is 100% effective, powerful and chemical-free, but sometimes other systems must be added. Oxygen is 100% effective and all-inclusive. Although the initial cost of the oxygen system is the highest, the long-term costs are the lowest.
Best Choice: You Decide
Each system is appropriate within certain parameters. Decide for yourself which system is most applicable for your situation.
AERATION
Advantages:
Air injection is inexpensive
and works well with water that has low levels of contaminants. It is low-maintenance and chemical-free. It will reduce the level of dissolved minerals, will settle out any particulates, and will off-gas the sulfur.
The single tank takes up a small footprint and fits in small spaces
Disadvantages:
However, it will not kill bacteria,
will not remove 100% of iron or manganese,
and will not soften the water.
The technology relies on the fact that air contains 19%-21% oxygen, and therefore will reduce but not remove all contaminants.
CHLORINE
Advantages:
If there there is aggressive iron bacteria in the well, a chlorine system is an excellent option.
It will kill all bacteria,
will fully oxidize the dissolved minerals,
will filter out chemicals and chlorine,
the water softener will treat any hardness,
and the price is in the average range.
Another advantage is that the flow rate requirement is only 6.5 gpm-9gpm.
Disadvantages:
Six tanks require ample space
Chlorine and salt must be purchased and added constantly
The injection tubing will clog and must be cleaned or replaced periodically.
There is an on-going expense of purchasing salt and chlorine (or hydrogen peroxide, which is more expensive).
OZONE
Advantages:
Chemical-free
Ozone is a powerful oxidant and will quickly oxidize dissolved minerals such as iron and manganese. The system requires a flow rate of 8 gpm - 10 gpm.
Ozone can penetrate the cell wall of a bacteria within seconds, whereas it may take up to an hour for chlorine to penetrate it fully.
Unlike chlorine, ozone is not residual and is off-gassed after it has served its purpose.
Nothing is added to the water, but the contaminants are all removed
Disadvantages:
The ozone pump makes a sound every time water is turned on. Over time, multiple components will clog, wear out, weaken, or need some sort of servicing, such as cleaning or replacement. For example, the ozone pump will wear down and will need to be rebuilt every two or three years, for about $400.
OXYGEN
Advantages:
Quiet
Salt-free
Chemical-free
Low-maintenance
Eliminates iron, manganese, sulfur, hardness, chemicals, bacteria, and even arsenic—all the problems we have here on Whidbey island.
The price for extended maintenance over time is the lowest long-term price of all the systems.
If additional systems are required, they will be included at lower than normal prices, or sometimes for no additional cost.
The system is custom-designed based on the results from a free extensive water test of over 130 contaminants.
Once installed, it is guaranteed to remove all undesirable contaminants.
Disadvantages:
Initial cost is higher than other technologies.
Requires flow rate of 10 gpm - 12 gpm.
My Personal Choice
Why did I choose the ECOsmarte oxygen system for my own house?
- The chlorine system did not appeal to me for a number of reasons, primarily because I do not like using chemicals or salt. Water softeners make the water feel slimy and impossible to rinse the soap off during a shower. The production of chlorine is destructive to the environment and is a chemical that is dangerous to produce and use.
- Aeration systems are not fully effective. I want totally clean water, not partially clean.
- I had an ozone system on my house for many years, but it was high maintenance and required frequent inspection. It also would not remove any calcium. My shower heads would constantly cake up with white deposits that were difficult to remove.
- The ECOsmarte oxygen system does everything the ozone system did, with the additional benefit of removing calcium and residually killing the bacteria in my pipes. The biggest benefit is that maintenance is easy and infrequent. Besides knowing that my water is safe and my pipes are clear, my favorite part is that my shower heads are clean.
