Product review (5 stars): So much better than the replacement " Holmes" filters! Even better than the one it came with! GREAT!!
Wow. I thought these were going to be flimsy & sub par to the regular ones. I was so wrong!!! These are thick, they have a metal reinforcement that insures it keeps its shape. I love these! 3 were cheaper than 2 of the  " Holmes" ones & other types. I will repurchase these again! The last ones I got to replace the original that came with my unit ( HCM 350w Germ free) were thin & did not last 1/2 as long as the ones that came in the units! These are much better!!!
