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 | 0.6522 mg/L | 4 mg/L | 16% | Safe |
| Nitrate | 1.3813 mg/L | 10 mg/L | 14% | Safe |
| Arsenic | 0.0013 mg/L | 0.01 mg/L | 13% | Safe |
| Chromium | 0.0108 mg/L | 0.1 mg/L | 11% | Safe |
| Lead | 0.0016 mg/L | 0.015 mg/L | 11% | Safe |
| Mercury | 0.0002 mg/L | 0.002 mg/L | 9% | Safe |
| Nitrite | 0.0881 mg/L | 1 mg/L | 9% | Safe |
| Haloacetic Acids | 3.9733 ug/L | 60 ug/L | 7% | Safe |
Vallejo's water quality is excellent — a basic filter for taste improvement is all you need.
Your water contains lead, 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 quality is excellent — all tested contaminants are well within EPA limits. A basic carbon pitcher filter is all you need to improve taste by reducing chlorine and minor impurities.
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 |
Vallejo uses a mix of surface water and groundwater sources. This means your water may contain a broader range of contaminants — both the organic compounds common in surface water and the dissolved minerals found in groundwater. A versatile filtration system like reverse osmosis or a multi-stage filter is often the best approach for mixed-source water.
Vallejo is served by 1 water system, serving a population of approximately 121,253 residents in Solano County.
Vallejo's water scores 93/100 — which is excellent. While your water meets all EPA standards, a basic carbon filter can still improve taste by removing residual chlorine. If you have specific health concerns or sensitive household members (infants, elderly, immunocompromised), a filter adds an extra layer of protection.
Based on Vallejo's water quality data, the most important contaminants to filter are Fluoride, Nitrate, Arsenic. 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.
Since Vallejo's water quality is excellent (93/100), an affordable pitcher filter ($20-$50) is all most residents need. Look for one certified to NSF/ANSI Standard 42 for chlorine taste and odor reduction. Brands like Brita or Clearly Filtered offer reliable, budget-friendly options.
For most Vallejo residents, a whole house filter isn't strictly necessary since your water quality score is 93/100. 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 Vallejo, 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.
