Excerpt: When upgrading our Renpho RP-AP088W with the RP-AP088-F1 filters, we were impressed by how seamlessly they replaced the original units. The 5-in-1 H13 True HEPA filtration captured even the tiniest particles, while the activated carbon layer tackled stubborn odors with ease. Using both filters in tandem (thanks to the dual-pack design) created a noticeable difference in our home’s air quality. The H13 True HEPA was sheerly effective at filtering microscopic pollutants, while the activated carbon neutralized cooking and pet smells. Though we’ve only used them for a month, the filters hold their integrity well, showing no signs of diminished performance. For those seeking reliable HEPA and activated carbon filtration, the RP-AP088-F1滤波器 (from RENPHO) is a straightforward and effective choice.
