Stage 2: Kinetic Degradation Fluxion Filter (KDF)
Once the sediment particles are removed, the water is pumped through the second stage filter designed for capturing heavy metal contaminants. The Kinetic Degradation Fluxion filter removes iron, lead, chloramine, arsenic, sulfur, algae, viruses, hydrogen sulfide, fungi, mercury, chlorine, and aluminum. It also controls and inhibits the growth of harmful microorganisms.

Is A Whole House Water Filter Right For You?

Is A Whole House Water Filter Right For You?

Finding a water filtration system to treat dirty tap water takes careful planning and research. Considering the investment, it only makes sense to audit the water quality in your entire home first. You may discover that the problem isn’t as widespread as you thought. In that case, you can consider a point-of-use water filtration system to treat the faucets most affected by contaminated tap water.

Discover: Low Cost Ways For Home Owners To Treat Contaminated Tap Water

Foul smelling water from multiple faucets in your household is a sure sign that the water entering your home has been compromised. To treat the water throughout your entire home, you need the power of a whole house water filtration unit.

Benefits of A Whole House Water Filter
While more costly than a POU (point of use) device, a whole house water filter has several benefits:

  • High capacity filters for treating water in high volume
  • Superior flow rate engineering to maintain consistent water pressure
  • Multi-stage filtration for treating heavy metals, chemicals, viruses, fungi, and many other pollutants commonly found in tap water
  • Low maintenance required (annual filter replacement)

Is Your Tap Water Contaminated?

A water test kit can quickly reveal whether the foul smell in your tap water is the result of hydrogen sulfide or just some lingering odor from the neighbor. You’re probably familiar with at least one of the signs on this list [1].

Here are 5 of the most common signs you may need a water filtration system to treat your tap water:

1. Spotted Glassware
Dishes that repeatedly come out of your dishwasher with unsightly spots is a sure sign that you are washing with hard water. Hard water is a widespread problem across many westerns states, where limestone can be found in abundance, the biggest source of hard water contamination.

High levels of calcium and magnesium in your water make it nearly impossible for soap to lather, which leaves your dishes just as dirty as when you left them. You’ll need a high quality water softener with activated carbon filters to restore your tap water to its healthy state.

2. Turbidity
If the water flowing from your faucet appears cloudy or opaque in a glass of water, you may be observing the presence of high levels of undissolved chemicals. High levels of minerals such as calcium and magnesium leached into public water systems after a heavy rainfall or floods could be the cause. Healthy drinking water is always clear in appearance.

3. Discoloration
Tap water that emerges yellow, orange, or rust in color is a sign of corrosion in your pipes or your water supply. Copper, lead, and iron are the most common culprits. The excess levels of rust can breed bacteria, while lead consumption even in small doses can be harmful to infants, the elderly, children and pregnant women [2].

4. Bleach Odor
Chlorine, once widely used by city water supplies to treat water, is relatively safe, but some dangerous byproducts can be produced when levels are excessively high. Trihalomethanes and haloacetic acids have been linked to an increased risk of cancer. If you detect a strong odor
of chlorine in your tap water, get your water officially tested.

5. Rotten Egg Odor
Among the most common signs of contaminated tap water, the presence of hydrogen sulfides is easily identifiable by the smell of rotten eggs. This colorless gas occurs naturally in groundwater, but can easily cause diarrhea or dehydration if exposed to bacteria.
