Frequently asked questions
Is this filter actually compatible with LG refrigerators that use ADQ72910901?
The model designation WD-F05-COMPAT-LG-ADQ72910901 indicates Waterdrop designed this as a compatible aftermarket replacement for LG refrigerators that use the ADQ72910901 cartridge. You should cross-check your refrigerator's model number on the Waterdrop compatibility chart or the Amazon listing to confirm a fit before ordering, as LG uses multiple filter styles across different lines.
How does the $14.99 single-filter price compare to buying a 3-pack?
The single-unit WD-F05-COMPAT-LG-ADQ72910901 costs $14.99, which is the lowest entry cost if you only want one filter. The WD-F05 3-pack lists at $29.99, putting the per-filter price at roughly $10. If you replace your filter every 6 months, the 3-pack covers 18 months and saves about $15 over buying three singles at the current price.
What contaminants does the NSF 42 certification cover?
NSF 42 is an aesthetic certification. It addresses chlorine taste and odor along with particulate matter that affects how water looks. It does not certify reduction of lead, cysts, VOCs, or pharmaceutical compounds. For those contaminants, filters need to also carry NSF 53, NSF 58, or NSF 401 certification depending on the substance.
