Flintar C102 Replacement Filter, Compatible with Miko Ibuki Air Purifier C102, MA-01, MA-04 and Okaysou AirMic 4S Air Purifier, High Efficiency Activated Carbon and Air Filter Set, 2-Pack

Filters work great.Saying Flintar reminds me of an 80's cartoon

These are great filters and quick shipping. We were told from a shop it would take awhile for them to get them, but we trusted Amazon. The filters fit perfectly.

These are working great for our air purifier! Thanks For the Great Price!

I was slightly worried that this filter wasn’t going to work for my Okaysou AirMic4S, but I decided to take a chance since Amazon offers free return. I am glad I did, the filter is fitting well and working perfectly!It is definitely comparable with the original one and easy to install. The filters are real HEPA and even come with more charcoal pellets than the original filter from the one in the purifier(see the attached image, the left is Flintar and the right is Okaysou).Thus far, the AirMic4S seems to doing a very good job of keeping our air fresh, reducing dust particles and is reasonably quiet. I will continue to buy these filters for my air purifier as they are a better price and doing excellent job.

These are great easy to install and works well.

These things are so wonderful!!! We have two birds so cleaning the air is important and it cleans the air very well, the size is perfect for any surface and it was so easy to install, works great

Works great. I have reordered these multiple times and will keep reordering. Cheaper than any store or online.

I purchased these filters for an Okaysou model I own. They are affordable, do a good job filtering dust/pet hair, and fit the model I have. I also find I can extend the life of the filter by using compressed air to blow out dust/hair a time or two before replacing them.
