    • Great Value

Looks great, fits like factory. I believe this is just as good as the original at half the price.

    • Highly recommend
Size: 5" x 5" x 5"
I've been using this brand for a few years instead of the ones from the manufacturer. There is a slight difference but the cost difference in savings makes up for it.

    • Pretty close but not identical
Size: 5" x 5" x 5"
This filter seems good. Especially for the money. However, the charcole hexagons are not completly full like in the medify branded filter where the hexagona are packed full. You can test this by holding them both up to light and see how it shines through to test that. Second, the prefilter mesh on this product has large holes and is not as fine of a prefilter as the medify product. Still seems to be a quality product, just not as much as Medify's but... hard to argue with the value you get with LINNIW. LINNIW is also made in China if that matters to you. Hope this is helpful for people, sorry i didnt post pics, its Christmas Eve day and i'm being lazy today. All the best, N ... show more
