Every everydrop Filter 4 (EDR4RXD1) filter we checked, side by side
"Certified for" comes from the certifier's own listing for that exact model code, not from the box or the Amazon page. Per year = 2 filters, because Whirlpool says to change it every 6 months. Prices as of November 12, 2026 at 12:18 PM ET. Certification listings checked October 23, 2026.

How we work it out: per filter = the Amazon price ÷ the filters in the pack. Per year = per filter × 2. Per gallon = per filter ÷ the gallons the certifier lists for that filter. A filter rated for more gallons costs less per gallon, but Whirlpool still says to change it every 6 months.
Taste-and-odor-only filters (NSF/ANSI 42) are fine if your water is safe and you only want it to taste better. They are not tested for lead or cysts. If you are not sure what is in your water, look up your water system.
Look at the model code, not the brand
Waterdrop sells two Filter 4 copies that look alike. NSF lists the plain WD-F07 for chlorine, taste and odor only. It lists the Waterdrop Plus WDP-F07 for lead, mercury and cysts (NSF/ANSI 53) and traces of medicines (NSF/ANSI 401). Filterlogic and GLACIER FRESH do the same: their lead listings are for FL-RF07-S and GF-8001 PLUS, while Amazon sells the plain FL-RF07 and GF-8001.
The code is in the Amazon listing's details (model or part number) and on the filter's label. Check it before you buy.
On October 23, 2026, the best-selling Filter 4 copies on Amazon were Waterdrop WD-F07, Filterlogic FL-RF07 and ICEPURE RWF0900A. All three are certified for taste and odor only. Waterdrop Plus WDP-F07 and ICEPURE PLUS RWF0900AH are the copies we could confirm for lead.
Waterdrop vs everydrop Filter 4
Waterdrop sells two kinds of Filter 4 copy. Only the Waterdrop Plus (code WDP-F07) is certified for lead. NSF lists it for lead, mercury and cysts, plus traces of medicines, for 300 gallons. Whirlpool's own Filter 4 is listed for lead, cysts and a longer list of chemicals, for 200 gallons.
The plain Waterdrop WD-F07 is the best seller of the two, and it is certified for taste and odor only. Neither Waterdrop filter, nor Whirlpool's, is listed for PFAS, even though Waterdrop's Amazon titles say "Reduce PFAS".
About the Whirlpool filter
NSF lists Whirlpool's Filter 4 (listing W11311161, model codes EDR4RXD1, EDR4RXD1B, WHR4RXD1, KAD4XD1 and Kenmore 9084) for NSF/ANSI 42, 53 (lead, mercury, cysts, asbestos, atrazine, benzene and other chemicals) and 401, for 200 gallons. NSF does not list it for PFOA or PFOS. Checked on listings.nsf.org on October 23, 2026.
EDR4RXD1, UKF8001, 4396395, WHR4RXD1 and KAD4XD1 are the same filter (UKF8001 is Maytag's number, WHR4RXD1 the Whirlpool label, KAD4XD1 the KitchenAid label). Match the number on your old filter.
Popular copies not certified to filter anything
- HMASAV HM004: NSF lists HM004 only as a replacement part tested for material safety, with no claim to reduce chlorine, lead or anything else. Read October 23, 2026.
- Filterlogic 5-pack (listed as "Filterlogic UKF8001"): Amazon gives no certified model code for this pack. NSF lists Filterlogic FL-RF07 for taste and odor only. Read October 23, 2026.
A seller's "NSF certified" or "tested to NSF standards" line is not a listing. We count a filter as certified only when the certifier lists that exact model code.
Questions people ask
Is there a cheaper everydrop Filter 4 that is certified for lead?
Yes. NSF and IAPMO R&T list the Waterdrop Plus WDP-F07 for lead, mercury and cysts (NSF/ANSI 53) and traces of medicines (NSF/ANSI 401), for 300 gallons. NSF and IAPMO also list ICEPURE PLUS RWF0900AH for lead. Check the code on the box: the plain Waterdrop WD-F07 and ICEPURE RWF0900A are certified for taste and odor only.
Is UKF8001 the same as EDR4RXD1?
Yes. Maytag UKF8001 and Whirlpool EDR4RXD1 (everydrop Filter 4) are the same filter. NSF lists Whirlpool's filter under the codes EDR4RXD1, EDR4RXD1B, WHR4RXD1, KAD4XD1 and Kenmore 9084.
Does everydrop Filter 4 remove PFAS?
Not as far as the listings show. NSF lists Filter 4 for lead, cysts and other chemicals, but not for PFOA or PFOS. Waterdrop's Amazon titles say "Reduce PFAS", but no certifier lists WDP-F07 for PFAS.
Is the Amazon Basics UKF8001 filter certified?
For taste and odor only. NSF lists the Amazon Basics copy (AMZN-UKF8001-S) under NSF/ANSI 42. It is not listed for lead.
What is the difference between everydrop Filter 1, 3 and 4?
They fit different fridges and are not swappable. Read the number on your old filter: EDR1RXD1 is Filter 1, EDR3RXD1 is Filter 3, EDR4RXD1 or UKF8001 is Filter 4.
How often should I change Filter 4?
Every 6 months. NSF lists Whirlpool's Filter 4 for 200 gallons. The certified Waterdrop Plus copy is listed for 300 gallons.
