Review on 🌬️ Enhance Indoor Air Quality with Aprilaire 401 Replacement Filter Purifier by Bim Cook

As another reviewer wrote, "This is the one” if you are looking to replace the filter media in the Space Gard 2400 filter pack. This was my third attempt at purchasing through Revain so I was relieved to realize that I had finally found the right product. Stairs like I had on my first try. But with two ovens I got a second chance and found that when working at ground level with the experience of the previous one it only took me about 5 minutes. However, it's a lot more work than just pulling out the old filter and putting in the new one. Is the paper fragile? Of course, it's not as strong as the often found filters that are reinforced with fiberglass and metal. I don't think the manufacturer recommends vacuuming this filter and untrained hands can damage it during installation.
