Frequently Asked Questions About the Standard Pre-Filter
Which Austin Air purifiers does the Standard Pre-Filter fit?
It fits full-size Austin Air purifiers, including the HealthMate, HealthMate Plus, Bedroom Machine and Immunity Machine. Choose white for White and Sandstone units, or black for Black, Graphite and Midnight Blue units.
Why replace the pre-filter?
The pre-filter catches larger particles like dust, hair and pet dander before they reach the main filter, helping it last.
Which prefilter color do I need?
Match the prefilter to your purifier’s color. The white prefilter is for White and Sandstone units, and the black prefilter is for Black, Midnight Blue and Graphite units. The filter inside is the same either way.
How often should I replace an Austin Air filter?
Austin Air designs its main filters to last up to five years under normal home use. The Austin “it” VOC carbon wrap is the exception, at about three months.
Can I use my FSA or HSA?
Yes. Austin Air purifiers and replacement filters are FSA/HSA eligible. Depending on your plan, you can pay with your FSA or HSA card at checkout, or pay another way and submit your receipt for reimbursement. Some plans ask for a letter of medical necessity, so check with your plan administrator if you’re not sure.
