Review on Fellowes Carbon Filters AeraMax Purifiers by Michael Ringgold

About 9 months after the purchase I start my last filter change in the 4-pack. The last filter was a bit cut off and I have a feeling my HEPA filter might get damaged if I keep using it until the next replacement bulb comes on. So my 4 packs become 3 packs but for the price I paid it was still a bargain at the actual $3 per filter. Since the price has gone up (now $5 for a filter) I will give another aftermarket brand. Chance. If the price was the same or at least lower than the competition I would reorder this item. At the new price ($5 per filter) it's still a 50% saving over the big name brand, but nowhere near the deal I got the first time ($2 per filter).
