True HEPA Replacement Filter for Macro Pro

I bought a smaller air purifier mainly because it had smoke filters available for it.
Before I know it there's no more smoke filters.

And now I can't buy filters at all. I wanted the one with the app for the rest of the house but all that will be useless without filter replacements

This replacement has been sold out for months. How can I get a replacement filter for my unit???

This is the most quiet, efficient, and reasonably priced Air Purifier, and the filters last a long time in our house!

Its ease ability to operate and change filter (the machine will tell you when you need to change filter). Ours last about 6 months, so you use two a year. that's' area of 500 - 700 sq ft.

My Dreo air purifier stopped working and upon calling Dreo they advised me to replace the filter, which I did. The initial filter that came with the original purchase lasted over one year, and while I will replace the filter more frequently, this is such a great filter. While there were other buying options, I chose to buy the Dreo brand simply because I had such good luck with the initial purchase.
