Flintar MD1-0022 True HEPA Replacement Filter, Compatible with Vornado Air Cleaner Purifier Model AC300, AC350, AC500, AC550, PCO200, PCO300, PCO375DC, PCO500 and PCO575DC (1-Pack)

As I said, these FLINTARS are a FANTASTIC OPTION to Original Manufacturer filter and are much less expensive. Density appears the same, they filter as they should, and they have the pull out TABS, for easy installation, and fit perfect.

This is a great filter for my Vornado air cleaner - I have purchased it a few times over the last 3 years and I have found it lasts a long time, easy to vacuum, reasonably priced, well packaged, quick delivery. I am very satisfied with it.

works great and fits like it should

Fits perfectly in both my Vornado air purifiers; I have 2 different ones but they both take the same filter. It's nice to be able to have the same quality for such a lower price. Will order again when it's time to change the filters.

I was hesitant to purchase this because I wasn't sure that the quality would be as good as the Vornado filters. I would say that these filters are great quality and it works with my Vornado PCO200 unit. The only issue I had was the subtle plastic smell of the filter when I first started up my air purifier. But after running it for a while the smell is less of an issue.Other than that I saved $12 by buying this filter and the quality is equal to the more expensive vornado filter. So I will definitely purchase these from now on.

Don't have much to compare it to, but it works just like the originals.

These last for several months and are very good quality.
