備用圓形海綿濾芯

Didn't realize how dirty the old filter was until I swapped this one in—now the airflow feels noticeably stronger. The sponge material is dense enough to trap dust but still lets air pass through easily.

This filter fit perfectly into my air purifier and the sponge material feels dense enough to actually trap dust. I’ve noticed less dust around the house since swapping out the old one.

I was worried about finding the right replacement filter, but this one fits the 730005 perfectly and the circular shape is exactly what I needed. It does a great job keeping the appliance running smoothly.
