Winix 5300-2 Air Filtration System

Winix 5300-2 comes with a multilayered air filtration/purification system:

replace air filters- mechanical pre-filter is used for filtering out larger particles like pet and human hair and similar.

- carbon air filter is used for capturing various odors, Volatile Organic Compounds (VOCs), smoke, and similar air pollutants. The carbon air filter is not washable and it should be replaced on average every 3 months.

- True HEPA air filter is used for capturing small particles. It captures 99.97% of 0.3 microns or larger particles, including various allergens like dust, smoke particles, pollen, mold spores, pet dander, microbes, etc.

- PlasmaWave air filtration system creates hydroxyls to neutralize bacteria, VOCs, gases, odors, and similar. PlasmaWave air filtration system emits very low amounts of harmful ozone - less than 10 parts per billion (0.01 parts per million), with OSHA ozone exposure levels of 0.1 parts per million or less, and EPA ozone exposure levels of 0.075 parts per million.

Note: PlasmaWave system may simply be turned off. After all, according to the manufacturer, Winix 5300-2 doesn't produce ozone at all, but after checking specifications and all available documentation, ozone is created in traces ... if at all ...

Winix 5300-2 Maintenance

Due to its size, the best option is to place Winix 5300-2 on the permanent location with some area free around the unit - 12-18 inches (~30 - 46 cm) behind the unit and 4 inches (~10 cm) on its sides, preferably on the flat floor.

Maintenance procedures include setting the unit to operate as required, keeping it clean, and changing the filters when required.

The carbon air filter should be replaced every 3 months and the HEPA air filter should be replaced every 12 months. Also, mechanical air pre-filter should be cleaned every 14-30 days, depending on the local conditions.

Since the level of air purification depends on the quality of air filters, it is of utmost importance to use the OEM air filter. Perhaps the best option is to get Winix 115115 Replacement Filter (Amazon link) which consists of 4 carbon and 1 HEPA air filters, which is enough for the whole year.
