★★★★★
Perfect fit and great air quality
The filter fit my Midea KJ300G perfectly and noticeably improved the air in my home. Installation was straightforward, and the purifier runs quietly with this filter installed. Highly recommend for allergy sufferers.
David L. January 2025
★★★★☆
Effective but replacement needed often
This HEPA filter does a great job at cleaning the air and reducing dust. However, I found that in my city, I needed to replace it closer to every 6 months rather than 8. Still, it’s a good value for the quality.
Emily R. February 2025
★★★★☆
Good quality but only for one model
The filter quality is excellent and keeps my air purifier running efficiently. The only downside is that it only works with the KJ300G model, so it’s not versatile. If you have the unit, it’s definitely worthwhile.
James K. December 2024
★★★★☆
Quiet and efficient replacement
I appreciate how quiet my air purifier is after swapping out the old filter for this one. It seems to trap dust and pet dander well. The price is reasonable compared to other HEPA filters on the market.
