These fit Vava VA-EE004, Surround Air MT-8400SF, Serenelife PSLAPU35, Levoit VITAL100, Oregon Scientific cf8410, Invisiclean Aura IC-5018 and Sensa IC-5120, Ivation IVAHAP300This listing is for the PRE FILTER ONLY which will extend the life of the HEPA filter. If you need Hepa filters for ANY of the machines I listed above, you can find them here on Amazon now for cheap. You can search for Levoit VITAL 100 ( B0859VX3R2 in the search bar) and you can get a 2 pack of hepas for $28. ALL of the models above take the same exact size filter and I own SEVERAL of these models.

These pre-filters can be replaced in ~2 minutes, and they extend the operational life of the main filter by at least 3X. Highly recommended.

Thanks!

Perfect relacement for the black pre-filter in my Oregon air filter. We have dogs so it’s nice to preserve the more expensive parts of the filter and replace the hairier pre-filter more often!

perfect for replacing more frequently. reasonable price. can choose to either dispose of or wash to use again.

Very pleased. I'm already ordering more of them. They seem to fit all of my air purifiers. Better than the original prefilter.👍🏻

no instructions for clues how too assemble and received one cracked

I was expecting the full HEPA filter (my fault for not reading the description more thoroughly), but this is only the black (carbon?) pre-filter only, and it includes 4 of them. I suppose it might extend the life of the HEPA filter but I was hoping it was just 1 complete new filter for my air purifier (Oregon Scientific brand)
