Research Reveals The Best Faucet Water Filters For Removing Contaminants
Many homeowners are unaware of the hidden dangers lurking in their tap water. While public water supplies are treated, they can still contain concerning levels of contaminants like lead, chlorine, bacteria, pesticides, and pharmaceuticals. Installing a faucet filter is an easy and affordable way to enjoy cleaner, safer water right from your kitchen sink.
Read on to learn more about the major tap water contaminants that can be removed with the right faucet filtration system.
Major Tap Water Contaminants to Filter Out
Here are some of the most troubling pollutants commonly found in tap water that a quality faucet filter can help reduce or eliminate:
- Lead - This neurotoxin can leach into water from old pipes and plumbing fixtures. Even small amounts are harmful, especially for children.
- Chlorine - Added as a disinfectant, chlorine can react with organic matter to form harmful byproducts.
- Bacteria - E. coli and other pathogens can infiltrate aging water systems and cause illness.
- Pesticides - Agricultural runoff allows these chemicals to get into drinking water sources.
- Pharmaceuticals - Residues of medications pass through wastewater treatment back into tap water.
Health Dangers of Contaminated Tap Water
What happens if you consume tap water containing contaminants day after day? Potential risks include:
- Lead poisoning, causing brain and kidney damage
- Gastrointestinal illness from pathogens like salmonella or giardia
- Increased cancer risk from long-term exposure to disinfection byproducts
- Developmental problems in children from toxins that impact the brain and nervous system
Benefits of Using a Faucet Filter
Installing a faucet mount water filter provides a convenient barrier between you and the contaminants in tap water. Benefits include:
- Improved taste and odor by reducing chlorine levels
- Reduced exposure to lead, bacteria, pesticides, pharmaceuticals, and other toxins
- Lower health risks from consuming cleaner water
- Cost savings compared to buying bottled water
Choosing the Best Faucet Filter Type
With a wide variety of faucet filter options available, how do you select the right system? Here we compare the three most common types of filters for effectiveness in removing tap water contaminants:
Activated Carbon Faucet Filters
Activated carbon filters use carbon particles to adsorb and trap contaminants. Water passes through the porous carbon material, allowing chemicals like chlorine and pesticides to attach to the surface and be captured. The pros of activated carbon filters include:
- Effective at removing chlorine, benzene, radon, and many industrial solvents and pesticides
- Simple design with no power required
- Inexpensive compared to other filter types
However, activated carbon filters have limitations. They are not effective at trapping heavy metals or fluoride. The pores also eventually get filled, requiring filter replacements.
Reverse Osmosis Faucet Systems
Reverse osmosis (RO) uses pressure to push water through a semipermeable membrane that filters out contaminants. RO removes:
- Dissolved solids like lead, mercury, arsenic, fluoride
- Microorganisms including bacteria, giardia, cryptosporidium
- Asbestos fibers
- Fertilizers, pesticides, herbicides
Drawbacks of reverse osmosis systems include slower water flow due to the pressurization required. They also waste more water than carbon filters. The membrane needs occasional cleaning and replacing when efficiency declines.
Ion Exchange Faucet Filters
Ion exchange filters use resin beads to attract and cling to copper, lead, and other mineral ions, while releasing more desirable ions like sodium or potassium into the water. They excel at removing:
- Lead
- Arsenic
- Nitrates
- Fluoride
However, ion exchange filters are not effective for filtering out smaller organic contaminants. The resin beads also eventually exhaust, requiring filter replacements.
Compare the Filtration Effectiveness of Each System
This table summarizes how well each of the three main types of faucet filters performs for removing specific water contaminants:
| Contaminant | Activated Carbon | Reverse Osmosis | Ion Exchange |
|---|---|---|---|
| Lead | Moderate | Excellent | Excellent |
| Bacteria | Good | Excellent | Moderate |
| Chlorine | Excellent | Good | Moderate |
| Pesticides | Good | Excellent | Poor |
As the table shows, reverse osmosis systems excel at filtering out the broadest range of contaminants. But they come at a higher upfront cost. Activated carbon provides good filtration at a lower price point. For targeting specific contaminants like lead or nitrates, ion exchange models are ideal.
Assessing Faucet Filter Costs and Maintenance
In choosing a faucet filtration system, it's important to look at both upfront expenses and the ongoing costs of filter replacements and maintenance.
Faucet Filter Purchase Price Comparison
On average, expect to pay:
- Activated carbon faucet filters: $15-$60
- Reverse osmosis systems: $150-$300
- Ion exchange filters: $50-$100
Factors like the number of filter stages, attachments, and quality of parts affect costs for RO and ion exchange models.
Ongoing Costs of Replacement Filters
The filter cartridges in faucet systems need replacing every 2-6 months. Replacement costs can add up. Carbon filters tend to be the most affordable, in the $15-$30 range. Expect to pay $30-$60 or more to replace RO or ion exchange filters. Tips to save on replacements include:
- Buying multipacks of filters to get bulk discounts
- Signing up for subscription delivery of replacement filters
- Using each filter for the full recommended lifespan
Installation and Maintenance Considerations
Most faucet mounts are designed for easy DIY installation. The filter attaches to your existing kitchen faucet, either directly or via an adapter. Beyond initial installation, ongoing maintenance is important for continued filtration effectiveness. This includes:
- Replacing filters per the manufacturer's recommended schedule
- Periodically cleaning the outside housing as needed
- Checking for leaks
- Following any specific maintenance directions for your model
