Upgrade AER1 Filter Replacement for Holmes Air Purifier, 2 True Filters + 4 Carbon Booster Filters, purple

This was exactly what I have been looking for! My air purifier is fairly old, %26 I needed a new filter %26 the black sponge piece to replace an old one. However, they have become somewhat hard to find, %26 are too expensive when I do find them. These were not packaged in a commercially-designed box, but came in a plastic bag, put in a cardboard shipping box w/bubble padding %26 mailer. The price wasn't bad, %26 I ordered two. Will definitely order again, both for me, %26 for my mom, who has almost the exact same air purifier and needs a new filter %26 sponge, too. I wish the air purifiers used an easily washable filter %26 sponge, rather than disposable, one-time-use, non-washable ones, to prevent the added expense to replace them and the added waste to the environment. Mom %26 I both have many environmental allergies %26 respiratory illnesses, so the HEPA air purifier does help. Neither of us smoke or have pets, but the high humidity this year has caused a nasty, musty, wet odor in my condo. The new filter, some DampRid units in different rooms, %26 some Lysol disinfectant anti-mold/mildew spray helped a lot! In the pictures, you'll see I got 2 filters %26 4 of the black pieces. In the 3rd pic, you'll see the black pieces sent are NOT like the black sponge piece that was in the air purifier. So far, it seems ok, but I'm not sure exactly what those pieces do, so I can't say for sure. They are very thin, %26 almost like a firm felt.
