Editor's Pick: After your home air purifier has been running for a while, it's time to replace the filter — airflow drops and odors linger. This True HEPA filter captures pollen, pet dander, and dust, and once swapped in, the machine's suction noticeably recovers. It fits the common 5300, C535, and P300 models, and installation requires no tools — done in just a few minutes.
