Philips FY3400/30 - HEPA and carbon filter for PureProtect 3400 air

Philips FY3400/30 - replacement filter for air purifiers

The FY3400/30 filter is an original Philips replacement filter for PureProtect 3400 series air purifiers, matched to models AC3420 and AC3421. Regularly replacing the filter keeps the device's filtration performance high.

Three-layer filtration

The filter consists of three layers: a pre-filter, a NanoProtect HEPA layer and activated carbon. This arrangement captures very fine particles, including allergens, bacteria and particulate matter, while the activated carbon helps reduce unpleasant odors in the room.

Lifespan and ease of use

With typical use, the filter maintains high filtration performance for up to one year. A compatible air purifier signals when the filter needs replacing with an indicator on the display, which makes the device simple to operate.

Compatibility

The filter is intended only for Philips PureProtect 3400 series air purifiers (models AC3420, AC3421) - you can check the exact model of your device on its underside.
