These are the contaminants your filter needs to address, ranked by how close they are to EPA limits.
| Contaminant | Detected Level | EPA Limit | % of Limit | Status |
|---|---|---|---|---|
| Fluoride | 0.6691 mg/L | 4 mg/L | 17% | Safe |
| Copper | 0.1973 mg/L | 1.3 mg/L | 15% | Safe |
| Chromium | 0.0119 mg/L | 0.1 mg/L | 12% | Safe |
| Mercury | 0.0002 mg/L | 0.002 mg/L | 12% | Safe |
| Total Trihalomethanes | 8.7941 ug/L | 80 ug/L | 11% | Safe |
| Nitrite | 0.1079 mg/L | 1 mg/L | 11% | Safe |
| Nitrate | 0.8096 mg/L | 10 mg/L | 8% | Safe |
| Arsenic | 0.0004 mg/L | 0.01 mg/L | 4% | Safe |
Based on Des Plaines's specific contaminant profile, here are the filter types we recommend.
Your water contains arsenic, nitrates, fluoride — reverse osmosis is one of the most effective filtration methods for removing these specific contaminants. RO systems push water through a semipermeable membrane that blocks up to 99% of dissolved contaminants.
Your water contains disinfection byproducts. Activated carbon filters use adsorption to trap these contaminants as water passes through the carbon media. They are highly effective at improving taste and removing organic chemicals.
Your water contains nitrates, which are particularly concerning for infants and pregnant women. Ion exchange filters swap harmful ions like nitrate for harmless ones like chloride, effectively reducing nitrate levels.
Our recommendations are based on city-wide data. For the most accurate results, test your home's specific water — contaminant levels can vary by neighborhood and plumbing age.

| Filter Type | Removes | Best For | Price | Maintenance |
|---|---|---|---|---|
| Pitcher Filter | Chlorine, taste, odor, some metals | Basic taste improvement, budget-conscious | $20 - $50 | Replace filter every 1-2 months |
| Faucet Mount | Chlorine, lead, some bacteria, VOCs | Convenient, no counter space needed | $20 - $80 | Replace filter every 2-3 months |
| Under-Sink Carbon | Chlorine, VOCs, PFAS, lead (certified models) | Families wanting better filtration without RO | $50 - $300 | Replace filter every 6-12 months |
| Reverse Osmosis | Lead, arsenic, PFAS, nitrates, fluoride, 99% of contaminants | Comprehensive contaminant removal | $150 - $600 | Replace filters annually, membrane every 2-3 years |
| Whole House | Chlorine, sediment, rust, VOCs, some metals | Filtering all water in the home | $300 - $1,500 | Replace filters every 6-12 months |
Des Plaines draws its water from surface water sources such as rivers, lakes, or reservoirs. Surface water is more susceptible to contamination from agricultural runoff, industrial discharge, and stormwater. It typically requires more treatment and is more likely to contain disinfection byproducts (like trihalomethanes) formed during the chlorination process. A filter that addresses chlorine and organic compounds is especially useful for surface water.
Des Plaines is served by 1 water system, serving a population of approximately 58,364 residents in Cook County.
Des Plaines's water scores 84/100, which is decent but has some elevated contaminants. A water filter is recommended to reduce Fluoride and Copper levels. This is especially important for households with children, pregnant women, or anyone with health sensitivities.
Based on Des Plaines's water quality data, the most important contaminants to filter are Fluoride, Copper, Chromium. We recommend a Reverse Osmosis System, which removes: Lead, Arsenic, PFAS/PFOA, Nitrates, and more. Different filter types target different contaminants, so choosing the right one depends on your specific water profile.
For Des Plaines residents on a budget, a faucet-mount filter ($20-$80) offers the best value. These provide better filtration than pitchers and are more convenient. Look for NSF/ANSI 53 certification, which means the filter is tested for health-related contaminants like lead. If your budget allows, an under-sink carbon filter ($50-$150) provides even better filtration for a modest investment.
For most Des Plaines residents, a whole house filter isn't strictly necessary since your water quality score is 84/100. An under-sink filter for your kitchen (for drinking and cooking water) is usually sufficient. However, a whole house filter makes sense if you want to reduce chlorine exposure during showers, protect your appliances from sediment, or have specific concerns about skin sensitivity to water chemicals.
Filter recommendations are based on publicly available water quality data from EPA and state regulatory databases. Individual water quality may vary based on your specific location within Des Plaines, the age and condition of your plumbing, and seasonal fluctuations. Always test your water for the most accurate results. The filter types recommended on this page are general guidance — specific product performance may vary. Consult with a water treatment professional for complex contamination issues.
