Find your Levoit, Coway or Blueair model number
Read the label before choosing a filter. Core 300S-P, AP-1512HH and 211i Max are model codes; a brand name alone is not enough.
Filter care and buying
Make the next filter change easier.
Find the model, understand the layers and choose the right pack.
Pre-filter, main filter or a complete replacement set?
Check which layer you need and what the pack includes. A reusable pre-filter and a replacement particle or carbon filter are different components.
Core 300, Mighty and 211: why the full model matters
Close names are easy to confuse. Use the complete model and filter code to separate Levoit Core, Coway Airmega and Blueair generations.
When to replace a Levoit, Coway or Blueair filter
Replacement intervals depend on the filter and how it is used. Compare the manufacturer’s guidance for Core 300-RF, Coway 3304899 and Blueair F2MAX.
Buy the right filter pack on Amazon, including abroad
Start with the model and reference, then check the actual Amazon item. OneLink can change the destination country without changing what your purifier needs.
