Austin Air HM250 Main Filter
The main filter for the HM250 air purifier is an integrated system incorporating a True Medical Grade HEPA filter along with six pounds of activated carbon, zeolite and potassium iodide. The HEPA portion of the filter is like the HM200 but the carbon blend has the addition of potassium iodide which enhances its ability to remove heavy odors, even formaldehyde. A new air purifier comes with the filters. These are replacements. (If you have an HM200 air purifier and want to upgrade the filter, this HM250 filter will fit it).
The HM250 Main Filter is ClearFlite Part No. 8015.
.This main filter works in both 110volt and 220volt units.
