4-Pack True HEPA Replacement Filter Compatible with VEWIOR A1, AMEIFU AP01W, KOIOS HQKJ-50 Purifiers, 3-in-1 H13 True HEPA Filters

I bought these air filters for my air purifier. They fit perfect. Filters work as they claim love the price bought it because it came as a four pack at the same price as one.

This ended up being the wrong size for my air purifier, but return and refund was really easy.

Not the correct size for the air purifier. It even has the same numbers on the bbox as mine takes and they are too small
