Find your Levoit, Coway or Blueair model number

A little guidance
Replace it with confidence.
Model names, filter layers, replacement timing and buying abroad.
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.
- 01
The complete model
Keep suffixes such as S, P, i and Max. Similar names can use different filters.
- 02
The filter and pack
Match the printed filter reference and check the number of filters included.
- 03
Your country
The initial references are checked for the US. Recheck local fit and delivery after an Amazon redirect.
Here to help
Need a hand?
Keep your full model code and country handy.
Where is my model number?
Look on the rear or underside label. Keep the complete code: Blueair 211i Max and 211+ use different filters.
Are these genuine filters?
Product buttons identify reviewed manufacturer-branded items. Buttons labelled Search Amazon open reference searches; their results are not approved products. Check the brand, seller, reference and pack quantity before ordering.
Why does Amazon open a different country?
Amazon OneLink and Global Earning may take you to a local item or search results. When the local match is unconfirmed or a check finds another variant, the standard-product button stays on Amazon.com and a separate link searches your local Amazon. Check the final product and delivery country. A redirect does not confirm that your regional purifier uses the same filter.
Can I wash the filter?
Only wash a component when your model instructions explicitly allow it. A washable pre-filter and a replaceable main filter are different parts.
Do you sell or ship the filters?
You buy directly from Amazon or its seller. They handle payment, delivery and returns. Some links are paid affiliate links.
