Whirlpool EDR1RXD1B vs EDR3RXD1B vs EDR5RXD1B: What’s the Difference?

Choosing between EDR1RXD1B vs EDR3RXD1B vs EDR5RXD1B is confusing because the model numbers look almost the same. They are three different Whirlpool fridge water filters, called Filter 1, Filter 3 and Filter 5, and each one is made for specific fridges. This guide explains how they differ, what the certification numbers mean, and how to pick the right one from our fridge water filters the first time. 

Key Takeaways 

• EDR1RXD1B, EDR3RXD1B and EDR5RXD1B are Filter 1, Filter 3 and Filter 5, not versions of the same filter. 
• They differ in size, mounting style and the fridge models they fit, so they are not interchangeable. 
• The maker lists different certified contaminant counts: 28 for Filter 1, 73 for Filter 3 and 27 for Filter 5. 
• All three are listed for replacement about every 6 months or 200 gallons (757 L). 
• Match the filter to your fridge's model number before you open the box. 

EDR1RXD1B vs EDR3RXD1B vs EDR5RXD1B at a Glance 

EDR1RXD1B, EDR3RXD1B and EDR5RXD1B are Filter 1, Filter 3 and Filter 5 in the same family of Whirlpool refrigerator water filters. They differ in size, mounting style, and certified contaminant count, and each fit, and certified contaminant count, and each fits specific fridge models. Here is how they compare: 

The figures come from Whirlpool's everydrop product pages for Filter 1, Filter 3 and Filter 5, and from our own product listings. The fridge model decides which filter you need, not the numbers in the table. 

• What is the same: all three are everydrop filters in the same Whirlpool family, they use Triple Filtration Technology, and the maker lists the same replacement interval for each. 
• What is different: size and weight, mounting style, part number, certified contaminant count, and the fridge models each one fits. 

What Each Filter Is Made For 

Each of the three filters is built for a different group of Whirlpool refrigerators. Here is what to know about each one. 

Filter 1 (EDR1RXD1B) 

Filter 1 is the small push-button filter. The maker lists a net weight of about 0.48 lb and certifies it to reduce 28 contaminants. It replaces part number W10295370A. You can order the EDR1RXD1B Filter 1 from our store. 

Filter 3 (EDR3RXD1B) 

Filter 3 is heavier, at about 0.8 lb, and has the highest certified contaminant count of the three, at 73. It replaces part number 4396841. On many fridges that use it, you press an eject button to release it from the base grille. Our EDR3RXD1B Filter 3 listing shows the current part details. 

Filter 5 (EDR5RXD1B) 

Filter 5 is certified to reduce 27 contaminants and replaces part number 4396508. It is made for select refrigerator models, so check your manual before you order. You can find the EDR5RXD1B Filter 5 in our fridge filter category. 

Filter 1 and Filter 5 have similar contaminant counts, but similar numbers do not make them interchangeable. Filter 2 (EDR2RXD1B) is a separate quarter-turn filter in the same family. 

Filter 1 vs Filter 3 vs Filter 5: Head-to-Head Differences 

Filter 3 stands out for its higher certified contaminant count, while Filter 1 and Filter 5 are close on that number but differ in part number and fit. Here are the three pairings people ask about most. 

EDR1RXD1B vs EDR3RXD1B (Filter 1 vs Filter 3) 

Filter 3 is certified to reduce 73 contaminants against 28 for Filter 1, and it weighs about 0.8 lb against 0.48 lb. Filter 1 is a small push-button filter, while Filter 3 is often released with an eject button in the base grille. They replace different part numbers (W10295370A and 4396841), so they are not interchangeable. 

EDR3RXD1B vs EDR5RXD1B (Filter 3 vs Filter 5) 

Filter 3 is certified for 73 contaminants and Filter 5 for 27. They replace different part numbers (4396841 and 4396508) and are made for different fridge models, so check your manual before you order either one. 

EDR1RXD1B vs EDR5RXD1B (Filter 1 vs Filter 5) 

Filter 1 and Filter 5 have almost the same certified contaminant count (28 and 27), but that does not make them interchangeable. They replace different part numbers (W10295370A and 4396508) and fit different refrigerators, so a swap may leave the filter unseated or leaking. 

What the Contaminant Numbers Mean 

The contaminant counts are the maker's certification claims, and a higher number does not mean a better fit for your fridge. Only the filter your fridge is designed for will seat and work properly. 

The maker names lead, chlorine taste and odour, pesticides, and pharmaceuticals among the contaminants each filter is certified to reduce. Taste and odour fall under aesthetic effects, while contaminants with a health effect are a separate category. 

Health Canada's guidance on drinking water treatment devices lists NSF/ANSI 42 (aesthetic effects) and NSF/ANSI 53 (health effects) among the performance standards for these devices. It strongly recommends buying one certified to the applicable standard, and it does not recommend specific brands. Use the certification as a quality check, then choose by fit. 

Why These Filters Are Not Interchangeable 

These filters are not interchangeable because they differ in size, mounting style and the fridge models they are made for. A filter that looks close can still fail to seat, leak, or stop water flow. 

• Different size: the three filters differ in physical size and weight. 
• Different release style: one pushes in, another ejects from the grille, and the Filter 2 in the same family uses a quarter turn. 
• Different fridge models: each filter is listed for particular refrigerators. 
• Different certification: the certified contaminant counts are 28, 73, and 27. 

If a filter does not fit easily, do not force it. Stop and check the number against your fridge model. 

How to Find Which Filter Your Fridge Uses 

Find your fridge's model number and check it against the manual or parts list, then match the filter number exactly. The old filter itself is often the quickest clue. 

1. Look at your old filter. Check the label or the side of the filter for a filter number such as Filter 1, Filter 3 or Filter 5, or a code that starts with EDR. 
2. Find your fridge's model number. It is often printed on a label inside the fridge, on a side wall or near the door frame. 
3. Check the manual or the parts list. Look up your model number to see which filter it lists. 
4. Match the number exactly. Choose the filter that matches your fridge, not the one that looks similar. 
5. Check the release style. Note whether your old filter pushes, twists, or ejects, and compare it with the new one before you open the box. 

If you are not sure, send us your fridge model number and the number on the old filter, and we will help you check. 

What the B in the Model Number Means 

The B at the end of EDR1RXD1B, EDR3RXD1B, and EDR5RXD1B appears on the maker's current listings of each filter. You will also see the same numbers without the B, such as EDR3RXD1. 

Listings differ between sellers, so do not rely on the letters alone. Confirm that the filter is listed as compatible with your fridge model before you order. 

How Often to Replace These Filters 

The maker lists all three filters for replacement about every 6 months or 200 gallons (757 L). Replace sooner if the water flow slows or the taste or smell changes. 

• Slower water flow: a clogged filter restricts the water. 
• Changed taste or odour: the filter is no longer doing its job. 
• Filter reminder light: many fridges show a reminder when a change is due. 
• Six months have passed: replace it on schedule, even if the water seems fine. 

Example: Ordering the Wrong Filter 

Here is a typical scenario. A homeowner sees a filter reminder on their fridge. They remember that the old filter was a small one, so they order a different filter that looks similar and has a lower price in their cart. 

When the box arrives, the new filter does not seat the same way as the old one. They realise the old filter said Filter 1, and the one they ordered was Filter 5. 

The takeaway: check the number on the old filter and your fridge model before you order. Because our return policy covers unused items only, it is best to confirm the match before you open the box. This is an illustrative example, not a customer story. 

Which Filter Should You Buy 

Buy the filter that your fridge manual or old filter lists, and do not switch based on contaminant counts alone.

Conclusion: Match the Filter to Your Fridge 

EDR1RXD1B, EDR3RXD1B, and EDR5RXD1B are three separate filters, not three versions of one. They differ in size, mounting style, fridge models, and certified contaminant counts. Find your fridge model number, check the number on your old filter, and order the one that matches. Replace it about every 6 months or 200 gallons.
