Review on Holmes Carbon HAPF60 Filter C (Black) 4 Pack - High-Performance Air Filter Bundle by Mack Cruz

I bought 2 packs of these filters when I bought the air purifier thinking I bought 2 complete replacement filters. The air purifier requires THREE of these filters (which ONLY are sold in packs of 2?!), PLUS THREE carbon filter elements that you literally have to attach to these filters by hand. buy both 2 parts separately and assemble them?! Terrible, inaccessible design. Other than that, as you can see in the old and new pics, these filters definitely did the job. Last summer my health deteriorated and it is now believed to be caused by severe mold. growth from leakage. Replacing (very) used filters, putting the air purifier in an area near spots where we suspect there might be mold in the wall, and revving up noticeably an entire floor's air quality in just one day improved and it keeps getting better. It's frustrating that I had to go to great lengths to find and order carbon filter mounting parts AND these other filters while I was terribly ill. , and in a pack of 3, which is enough for a complete filter change!
