Replacement Filter Compatible with Dr.J Professional AP401 AP402 & GCZ AP402 Air Purifiers, 4-Stage Filtration CADR 400+ m³/h Air Purifier for Dust Odor Smoke (1 Pack, White)

The description was misleading. Make sure you check your filters measurements before purchasing. This was a few inches too short for my DRJ. I should have known by the price that it was just too good. Bummed

This is not a name brand but one made by another company. The filter looks like it is working but the image of a filter shows on the screen on the machine It never did that with the filters made by the same company.

The machine is so simple to use.. You basically just unpack, insert the filter, plug it in and it automatically goes to work. This product is very quiet and has cut back on my dusting.. The air even looks crisper.. I only wish that it released a nice room scent freshener...The only downfall is that it continues to shut off and doesn't help much with the odors of smoke...🤨 Needs some Improvement.....

These are great filters and a perfect fit. They really pick up a lot of stuff in the air.

Was the right item and received in a timely manner.

Great filters help keeps air clean!

22.5 oz instead of 19.2 at grocery stores.. Great price. Well packed.

I Love it! I had a hard time finding the right one, but Walmart had it! Thank You!

these are awesome air filters my room smells so refreshing. these are my second buy they are remarkable filters

I like this air purifier. It's very quiet - I finally had to change out the filter and it was very easy to install new one...another reason to like it.
