Hunter 30963 HEPAtech Tower Replacement Filter for Models 30710 and 30711

Want proof of how well the filter works? Check out the image I uploaded under "customer images." The awful gunk that clogs this filter by the time I change it proves that it's protecting my asthmatic child. It also proves that it's a good thing these filters come in two-packs. You've gotta stay on top of these machines or their effectiveness is drastically reduced by clogged and filthy filters.

By the way, my machine is a Hunter 30714. I don't know why that model's not listed as one of the ones that takes this filter, but I checked, and this is the correct replacement filter. It fits perfectly into the machine. It's well worth the money when you look at what's stuck to the filters... if it weren't in there, it'd be in your lungs. And you can't, as of yet, order replacement lungs on Amazon.

When I received this item it came wrapped in cellophane and fit neatly into my Hunter air purifier. Works great!

It says 99% and I believe it. It works well, but you have to understand that as the efficency of the filter rises, the speed it goes through the machines is slower. So excellent filtering ability.. low volume on the air. IF.. if you put this filtering unit in an old persons bedroom and just keep it running, it would be ideal. It would decidedly have a positive effect for folks who have pneumonia in the winter.
