With the HEPA filter by Philips, you can clean fine particles, bacteria, and viruses from the air. The carbon filter ensures that odors and gases disappear from the air. To make your Philips air purifier work optimally, it's important that you replace the HEPA and carbon filter on time. The filters for Philips air purifiers fit into any air purifier. When making your choice, make sure the filter fits in your air purifier.
