Product review (5 stars): A great deal and they work great
A great deal and they work great. I was having issues with static wherever I set the humidifier, ans Aprilaire 700.  I was told by an repair guy that I should use the Aprilaire filters and not the after market ones that are cheaper & readily available everywhere. On a recent visit he showed me that they are a little thicker & manufactured differently so they retain water better. Since using them the static went away and when I check them I see they do retain much more water and last a lot longer. Just another example of you get what you pay for - buy the right product.
