How to tell them apart
- Read the old filter. Look for EDR3RXD1 / Filter 3 / aqua, or EDRARXD1 / Filter A / blue. [S1] [S2]
- Don't swap by capacity alone. Both sheets use the same 200 / 100 gallon capacity line, so capacity won't tell them apart. [S3] [S4]
- Check the other everydrop colors if yours isn't aqua or blue. Filter 1 is purple, Filter 2 is orange, Filter 4 is green. [S5] See Filter 1, Filter 2 vs Filter 1 and Filter 4.
After you change it
Both data sheets say to flush the water system after changing the filter, and to follow the owner's manual for the exact steps. [S3] [S4]

FAQ
Is Filter 3 the same as Filter A?
No. everydrop sells them as separate products: Filter 3 (aqua, EDR3RXD1) and Filter A (blue, EDRARXD1). [S1] [S2] Whirlpool lists them under different filter groups. [S5]
Is EDR3RXD1 the same as WHR3RXD1?
Whirlpool's store lists both as Filter 3 options. [S5] The Filter 3 data sheet we read lists EDR3RXD1, EDR3RXD1B and KAD3RXD1 as replacement filters. [S3]
Is EDRARXD1 the same as WHRARXD1?
Filter A's data sheet lists EDRARXD1, EDRARXD1B, WHRARXD1, WHRARXD1B, KADARXD1, KADARXD1B, MAYARXD1, MAYARXD1B, W11536439 and W11486187 as replacement elements for the same system. [S4]
Is Filter A the same as Filter 1 (EDR1RXD1)?
No. Filter 1 is purple EDR1RXD1. Filter A is blue EDRARXD1. [S2] [S5] See Filter 1.
What we could not verify
- Whether Filter 3 and Filter A fit the same fridges. Whirlpool and everydrop treat them as separate filters, so we don't claim they're interchangeable.
- What "PID" means on the capacity line. Neither data sheet defines it.
- A fridge model list. everydrop's filter finder didn't return a list we could cite, so no models are added yet.
- NSF database confirmation for EDR3RXD1 or EDRARXD1.
- Install location and step-by-step photos for each filter. The data sheets point to the owner's manual for install and flush steps.
