Zero Water filters have gained popularity due to their claim of removing virtually all dissolved solids from water, leaving it “99.6% pure.” But how well do they live up to this claim, and are they worth the investment? This comprehensive guide will delve into the pros and cons of Zero Water filters, providing you with an informed decision.
How Does Zero Water Filter Work?
Zero Water filters employ a five-stage filtration system:
1. Sediment Pre-Filter: Removes coarse particles like dirt and rust.
2. Activated Carbon Filter: Adsorbs organic contaminants, chlorine, and pesticides.
3. Ion Exchange Resin: Exchanges ions with dissolved solids, removing minerals and metals.
4. Reverse Osmosis Membrane: A semipermeable membrane that selectively allows water molecules to pass through while blocking larger molecules.
5. Ultraviolet (UV) Lamp: Kills bacteria and viruses (optional in some models).
Benefits of Zero Water Filters
Removes Dissolved Solids
Zero Water filters effectively remove a wide range of dissolved solids, including:
- Calcium
- Magnesium
- Sodium
- Chlorine
- Lead
- Mercury
- Pesticides
Purified Water for Drinking and Cooking
The purified water produced by Zero Water filters is ideal for drinking, cooking, and preparing baby formula, as it removes impurities that can affect taste and health.
Reduces Scale Buildup
By removing dissolved solids, Zero Water filters prevent scale buildup in appliances like coffee makers and kettles, extending their lifespan.
Drawbacks of Zero Water Filters
Slow Filtration Rate
Zero Water filters have a relatively slow filtration rate compared to other types of filters. It can take several minutes to fill a water bottle or pitcher.
High Maintenance Cost
Zero Water filters require regular filter replacements, which can be expensive. The manufacturer recommends replacing the filters every two months or 25 gallons, whichever comes first.
Acidic Water
The ion exchange resin in Zero Water filters can lower the pH of water, making it slightly acidic. While this is generally not harmful, it may not be suitable for certain uses, such as watering plants or keeping fish.
Removes Beneficial Minerals
Zero Water filters remove both harmful and beneficial minerals from water. While this may be desirable for some users, it can also lead to mineral deficiencies if not supplemented through other sources.
Potential for Contamination
If the Zero Water filter is not properly maintained, it can become a breeding ground for bacteria and mold. Therefore, regular cleaning and filter replacements are crucial.
Is Zero Water Filter Right for You?
The decision of whether or not to purchase a Zero Water filter depends on your individual needs and preferences. Consider the following factors:
- Water Quality: If your tap water contains high levels of dissolved solids or contaminants, a Zero Water filter can provide significant benefits.
- Budget: Zero Water filters are more expensive than some other types of filters, so consider your budget before making a purchase.
- Maintenance: Zero Water filters require regular filter replacements and cleaning, which can be a hassle for some users.
- Mineral Intake: If you are concerned about removing beneficial minerals from your water, you may want to consider a filter that selectively removes only harmful contaminants.
Alternatives to Zero Water Filters
If Zero Water filters do not meet your needs, consider these alternatives:
Brita Filters
Brita filters are less expensive than Zero Water filters and remove a wide range of contaminants, but they do not remove all dissolved solids.
Reverse Osmosis Systems
Reverse osmosis systems are more expensive than Zero Water filters but provide the most thorough water purification, removing virtually all contaminants, including dissolved solids.
Activated Carbon Filters
Activated carbon filters are a good option for removing chlorine and other organic contaminants but do not remove dissolved solids.
