Recommended filters for Newark
Filters matched to the specific contaminants in Newark's water supply.
Filter certified for lead (NSF/ANSI 53 or 58)
$180-$750When lead is a concern, use a filter certified for lead reduction under NSF/ANSI 53 or 58.
Carbon filter certified for VOCs (NSF/ANSI 53)
$180-$599Activated carbon is effective for disinfection byproducts. Look for NSF/ANSI 53 VOC reduction.
Reverse osmosis certified for chromium (NSF/ANSI 58)
$429-$599Chromium-6 needs reverse osmosis for reliable reduction. Standard carbon filters do not address it.
