NSF 42 or NSF 53: which do you need?
NSF/ANSI 42 covers chlorine taste and odor. NSF/ANSI 53 covers health claims such as lead and cysts. NSF/ANSI 401 covers traces of medicines and a few other compounds. Each listing names an exact model code, so a brand can sell one filter listed for 42 and a look-alike listed for 53.
If you only want better tasting water, the taste-and-odor copies in the table cost less per filter than the lead ones. They are rated 300 gallons to Whirlpool's 240. If you want lead reduction, pick from the green rows. The cheapest of them is the Waterdrop Plus, a 3-pack.
What NSF lists for Whirlpool's own Filter 5
NSF lists Whirlpool's own Filter 5 (EDR5RXD1, trade name PWF-NL240V) for NSF/ANSI 42, 53 (lead and more) and 401, for 240 gallons. Checked November 3, 2026.
Whirlpool also sells a lower-cost Filter 5, the EVFILTER5, at $27.99 a filter. NSF lists it for chlorine (42) and lead (53), for 240 gallons. It is not listed for cysts or mercury.
Waterdrop, ICEPURE and Tier1 listings
Waterdrop sells Filter 5 copies under three codes. NSF lists WD-4396508, WD-F02 and WD-F03 for NSF/ANSI 42 only. The Waterdrop Plus WDP-F02 is the one listed for 42, 53 and 401.
ICEPURE's lead version is RWF0500AH, listed for lead, cysts and mercury. The plain RWF0500A is listed for taste and odor only, so check the code before you buy.
NSF lists Tier1's RWF1020P for 42, 53 and 401. The Tier1 filter sold on Amazon for Filter 5 is model RWF1020, a different code, so that listing does not cover it. For lead, buy the Waterdrop Plus.
Which Whirlpool filter do I have?

Common questions
What is the cheapest NSF certified replacement for Whirlpool 4396508?
For lead, the Waterdrop Plus WDP-F02 3-pack: NSF lists it for NSF/ANSI 53, and it has the lowest price per filter of the filters we found that NSF lists for lead. If you only need chlorine taste and odor (NSF/ANSI 42), the plain Waterdrop, ICEPURE and Filterlogic copies cost less per filter, but none of them is listed for lead.
Is Waterdrop 4396508 certified for lead?
No. NSF lists the plain Waterdrop codes (WD-4396508, WD-F02 and WD-F03) for NSF/ANSI 42 only: chlorine, taste and odor. Some ads add NSF/ANSI 372, which covers lead-free parts, not lead removal. The lead version is Waterdrop Plus WDP-F02, listed for 42, 53 and 401.
Is Whirlpool's own Filter 5 certified for lead?
Yes. NSF lists Whirlpool's EDR5RXD1 for NSF/ANSI 42, 53 (lead, cysts, mercury and more) and 401, for 240 gallons (checked November 3, 2026). Whirlpool's lower-cost EVFILTER5 is listed for chlorine (42) and lead (53) only.
Is 4396508 the same filter as EDR5RXD1 and Filter 5?
Retailers list 4396508, 4396510 and Kenmore 46-9010 as fits for Whirlpool's everydrop Filter 5, whose part number is EDR5RXD1. Whirlpool's Filter 3 (EDR3RXD1) and Filter 4 (EDR4RXD1) are different filters. Match the number printed on your old filter.
Is NSF 42 or NSF 53 enough?
NSF/ANSI 42 covers taste and odor. NSF/ANSI 53 covers health claims such as lead and cysts. If you want lead reduction, buy a filter whose exact model code is listed under 53.
Is ICEPURE PLUS certified for lead?
Only the version sold under code RWF0500AH. NSF lists RWF0500AH for lead, cysts and mercury (NSF/ANSI 53). NSF lists the plain RWF0500A, the code Amazon shows on the 1-pack and the 2-pack, for taste and odor only.
Is PUREPLUS certified for lead?
Aquazon's lead listing is PP-RWF0500AH. The PUREPLUS 4-pack is sold as PP-RWF0500A, which NSF lists for taste and odor only, and the 2-pack shows a different code, RWF0500AH. For lead, buy the Waterdrop Plus WDP-F02.
Is Tier1 certified for lead for Filter 5?
Not the one sold for it. NSF lists Tier1's RWF1020P for 42, 53 and 401, but the Tier1 filter sold on Amazon for Filter 5 is model RWF1020, a different code. For lead, buy the Waterdrop Plus WDP-F02.
Is Refresh R-9010 certified for lead?
NSF has no listing for the Refresh R-9010. For a Filter 5 copy that NSF lists for lead, buy the Waterdrop Plus WDP-F02.
How often should I change it?
Whirlpool says every 6 months, and NSF rates its Filter 5 at 240 gallons. The copies are rated 300 gallons. Plan on 2 a year.
