You guys are asking too much for replacement units.

But way too expensive. I’d also like to be able to recycle used cartridges.

my out of warranty unit was the issue not the replacement kit! I'm bummed out to say the very least I never got the opportunity to experience the greatness of good clean air both my daughter and I need!

Freight cost on the replacement filter is a rip off!

The components are a perfect fit and easy to change and work perfectly. The one thing I do miss is the recycling option they used to offer. Now I have these two, large metal objects that I don't want to throw away, and since my local recycling program doesn't recycle something like this, I'm not sure where to take them!
