Frequently Asked Questions About the HealthMate Filter

Which Austin Air purifier does the FR400 fit?

The FR400 is the replacement filter for the Austin Air HealthMate (HM400) in every color. Choose the white prefilter for White and Sandstone units, or black for Black and Midnight Blue units.

What's the difference between the FR400 and FR450?

Both have 60 sq. ft. of medical-grade HEPA. The FR450 for the HealthMate Plus adds potassium iodide-impregnated carbon for VOCs and chemicals. The FR400 uses activated carbon and zeolite for everyday odors and gases.

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.
