Product review (5 stars): Great quality and price
After I asked the question about the metal lattice support running through the middle of it and got answers, I was convinced enough to buy the product. It arrived in four days and it was as I expected with the metal core. I am very satisfied with this purchase and am currently using one of them in my humidifier. I'm happy that it was available in bulk for a great price (I bought 12 for $22) and would recommend it to anyone with the type of humidifier that this filter fits.
