Cheap Air Purifier

This is a Holmes Air Purifier model HAP115Z. They are something less than 20 bucks at Wal Mart.

They charge like 7 dollars for the filter alone but you can buy a cut to fit filter with charcoal for about 12 dollars and make a LOT.

You can reuse the plastic grate that comes with the cut to fit filter so it only takes a few minutes to cut a new one.

Then it just sits flat in the back of the filter.

Cheap and Easy!
