Frequently asked
What water filter do I need in Bakersfield?
Based on the published record: PFAS: PFOS 8.4 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024 (+2 more PFAS detected). This calls for reverse osmosis, or carbon certified for PFAS, certified to NSF/ANSI 53 or 58, with PFOS/PFHxS/PFNA named on the listing. Lead 1.3 µg/L, below the 15 µg/L action level; detected below the limit. If you choose to filter, look for lead-certified carbon filter, or reverse osmosis, certified to NSF/ANSI 53 (lead). Lithium 14.8 µg/L, above the 10.0 µg/L EPA health reference level; above a health screening level, not a legal limit. If you choose to filter, the treatment depends on the contaminant: check the certifier's listing for each one. Choose a model whose certification names each contaminant you need to treat.
Does "NSF certified" mean a filter removes everything?
No. Certification is per contaminant: a filter certified to NSF/ANSI 42 for chlorine taste says nothing about lead or PFAS. Check the certifier's listing (NSF, WQA or IAPMO) for the exact model and the exact contaminant.
Is a pitcher enough for lead in Bakersfield?
A pitcher certified to NSF/ANSI 53 for lead reduces lead in the water you pour through it; replace cartridges on schedule. For a lead service line, replacing the line is the lasting fix; ask the utility about its replacement program.
