KNKA Genuine Air Purifier Replacement Filter for APH4000, Standard Filter

Quality made filter pack (2 units), is very well made, & durable. It has a fine mesh screen filter, followed by a charcoal filter which is very good for when I use my wood burning stove. Filters the air great!! Thanks Brian K.

Perfect match for our air purifier.

Glad I bought extra ones when I bought my air purifier. These are great I had bad dog smell. I had went nose blind n woke up and went yuk. These air purifier and filter cleared my home in around a week . I got one for upstairs and one down stairs. They say 300 sq. Ft. They did a little bit better then that. Very happy.

Perfect fit! One on the left is new filter. One on right is old filter. I maybe waited too long to replace. I waited 4 months instead of the recommended 3 months to replace filters.

You can see how EASY it is to change. Great value. Minimal noise. It’s not drastic. Improves smells and air quality. This one’s a great choice for the replacement filters. Size is exact for this model.

It has been only few weeks since I had the purifier. So far works fine. Removes strong cooking odors.

Filters are great quality. My living room has never been so pleasant.

We love are air cleaner.
