winix 5500 2 air purifier filter replacementWinix 5500-2 uses Filter H (item number 116130) consisting of both true HEPA air filter and AOC carbon filter - so change them both at the same time.

Note: according to the Winix 5500-2 manual, PlasmaWave doesn't emit any ozone. However, if one digs little bit deeper, PlasmaWave system of Winix 5500-2 emits traces amounts of ozone, up to 10 parts per billion (0.01 parts per million) - if any.

According to the OSHA ozone exposure levels should be 0.1 parts per million or less, and EPA ozone exposure levels should be less than 0.075 parts per million.

For short, amount of ozone that Winix 5500-2 emits are far below any significant level. But, for those that wants to be absolutely sure, PlasmaWave system can be turned off.

Again, negative ions produced by PlasmaWave doesn't mean ozone production, so if there is ozone produced/emitted, its levels are very very low.
