THE UNINVITED GUEST LIST
Your fall plans don’t need a plus-one.
01
Pollen tags along
Outdoor allergens can find their way indoors through open doors and windows, or hitch a ride on clothes and pets.
02
Dust gets comfortable
Blankets, rugs, and everyday movement can stir settled dust back into the air. A cozy room still deserves a cleaner-air routine.
03
Dander joins the cuddle
More couch time with your favorite companion can mean more airborne pet dander. Keep the cuddles. Filter the air.
Good design gets noticed.
Best for filtering smoke and allergens

THREE LAYERS. ONE CLEANER-AIR ROUTINE.
WHAT’S INSIDE
Small particles. A serious filter.
Medical-Grade H13 HEPA
Captures 99.97% of airborne pollutants under filter test conditions, including allergens and pet dander, as air passes through the filter.
A pre-filter
The first layer catches larger particles before they reach the HEPA filter.
Activated carbon, too
Helps reduce smoke, odors, and VOCs alongside particle filtration. Because a comfortable home is about more than what you can see.

THE ALLERGY-SEASON CHEAT SHEET
A few things worth clearing up.
Can it help with airborne allergens?
The Medical-Grade H13 HEPA filter helps capture airborne particles, including allergens and pet dander, as air passes through it. It complements regular cleaning and efforts to reduce allergen sources; it does not remove every allergen from a room.
Does the air-quality sensor detect pollen?
The sensor reports particle-based air quality. It is not a pollen counter or an allergen-identification test, and a good air-quality reading does not mean a room is allergen-free.
Where should Max live?
Choose a bedroom or living area where you spend time, with clear space around the intake and outlet. Max covers up to 1,950 square feet. Keep it away from direct heat, splashes, and blocked airflow.
Why add Max to my allergy-season routine?
Regular cleaning tackles surfaces. Max helps capture airborne pollen, dust, and pet dander as air passes through its Medical-Grade H13 HEPA filter—making air care another useful part of your allergy-season routine. Quiet settings and app controls make it easy to fit into everyday life, alongside regular cleaning and reducing allergen sources.
When is it time for a fresh filter?
Replace the 3-in-1 Filter Max about every six months for best performance. Max tracks filter life. Follow the care instructions and adjust maintenance to your home’s conditions.
