Austin Air Allergy Machine Replacement Filter FR405B, White
Replacement Filter for the Austin Air Allergy Machine with Pre-Filter
The Austin Air Allergy Machine is designed specifically for people with asthma and allergies. Its unique design increases airflow, filtering allergens from the air immediately. Clinical trials have shown that using the Allergy Machine significantly reduces hospital visits for young asthmatic children.
All standard-size Austin Air units are interchangeable with standard-size filters. If you own a HealthMate and wish to upgrade to the Allergy Machine, simply purchase this replacement filter.
⚠ Before ordering, confirm the correct size and type to avoid restocking fees on incorrect returns. Check the label on the underside of your unit—Model HM400 indicates a standard-size filter.
4-Stage Filtration Process:
✅ Stage 1 – Large Particle Pre-Filter – Captures visible particles such as dust, hair, and pet dander.
✅ Stage 2 – Medium Particle Pre-Filter – Traps smaller airborne particles like mold spores and pollen (color may vary: gray, blue, or green).
✅ Stage 3 – Medical-Grade HEPA – 60 sq. ft. of True HEPA captures 99.97% of particles 0.3 microns and larger and 99% of particles 0.1 microns and larger, including allergens, bacteria, and viruses.
✅ Stage 4 – Military-Grade HEGA Carbon Cloth – High Efficiency Gas Arrestance (HEGA) technology provides an extensive surface area for the adsorption of chemicals, gases, viruses, and bacteria.

This is the combination my nutritionist approves
Outstanding product and ingredients for eye health with great results
Village Green staff is outstanding and helpful, Louis, Tatiana, Kirstie, & Kala above and beyond
I have used this for many years and like it a lot and will keep on using it
I've been using this for decades. Natural, minimal chemicals that retard the development of stink producing bacteria. Long-lasting on the skin, and months of use per item.
I was asked to write a review I don't know if what I have to say would help but here it is. I am 74 years old and have trusted Village Green for years. Trust is something you earn in my opinion, and they have fulfilled their side of each purchase with professionalism, and I fulfilled mine with loyalty.
Good product
It’s lowering my cholesterol.
Anytime I need an expert CARING voice to help me make my supplement buying decisions I always come here. So grateful for the time they offer each customer.
Gives me my essential amino acids. I put it in my coffee
I found out about Jamaican Dogwood years ago from my herbalist Leslie Alexander, still practising in Erie Pa. It stops pain, doesn't bring me or down and If I need to sleep, it lets me. Great herb. Great price, Thank-you, Debb
Best establishment in the metro area! I have been using the Apothecary for almost 50 years years and now my family does as well. They all are knowledgeable, helpful and ready to answer any questions.
I’ve been depending on Jarrow’s Ideal Bowel Support and think it’s very helpful.
