4 Pack 3-in-1 True HEPA Filters Compatible with Pure Enrichment PureZone Air Purifier, 3-Stage H13 True HEPA Replacement Filter, Part # PEAIRFIL

We use this in our air filter all night in our son’s room. We have an old dust house and will stand by these filters. They work amazing and we don’t even have to dust anymore in his room and it stays pristine for his little lungs. I would rather run an air purifier with these filters than a blue light. I can sleep in peace knowing we won’t be getting sick or sleeping in a dirty environment. Great quality and easy to replace.

These work in my PureZone 3 in 1 units. They don't look 100% identical to the OEM filters, but they fit snugly and seem to have equivalent performance and longevity. To me, the price difference makes these the obvious choice.

They are great!

Fit perfectly and they are easy to install.

good product- it's cost effective and works perfectly with our Pure air purifiers. :) I get this auto delivered because it is so reliable. :)

Fit perfectly and a great price

As advertised

I researched the best price and quality for these filters and settled on these. I’m glad I did. Great price and quality. I recommend.
