Why this filter
What it filters
Independent certification confirms that this filter, when used in the listed system ADQ73613401-S, reduces lead and mercury, among other listed substances. That does not mean it removes everything or guarantees safe tap water. Open the test details below for the full list and limits.
Which system these results apply to
These test results apply only when used in ADQ73613401-S. They cover the filter and system together, not the filter on its own. Confirm your installed system before relying on these results.
How this compares
This is a checked replacement, not a Best Overall or Best Value winner yet. Before choosing a winner, we need other filters we can trust, a fair comparison of how they work and how reliable they are, and current prices including shipping.
Filtration tests and details
These records explain which filter results we have checked and what their limits are. The same certification name does not mean two filters work equally well.
Standards used in these tests
The listings use NSF/ANSI 42, NSF/ANSI 53. A shared standard name does not mean two filters reduce the same substances or have the same tested capacity or performance.
How the certification identifies this filter
This filter is shown here as LT800P. The certification listing uses ADQ73613401-S. Reviewed model-mapping evidence connects that certified identity to this product; matching brand names or retailer titles alone would not establish this connection.
What we have verified about filtration
NSF's independent listing for certified model ADQ73613401-S certifies reduction of 2,4-d, asbestos, atrazine, benzene, carbofuran, cysts, lead, lindane, mercury, p-dichlorobenzene, toxaphene under NSF/ANSI 53, a standard covering specific health-related contaminant reductions. This means reduction under the certification's test conditions—not removal of every contaminant or a guarantee about your tap water. Certification establishes verified capabilities; it does not establish superiority over another filter.
Chlorine, chloramine and particles
The exact-model NSF/ANSI 42 listing certifies reduction of chlorine, fine particles (Particulate Class I), taste and odor. These are separate verified capabilities from the health-related reductions above; a generic certification logo alone would not tell us which of them an alternative filter provides.
