Breathe Cleaner, Safer Air with the R400 Air Purifier (The Everyday Air Purifier)
If you’re trying to reduce airborne chemicals and allergens in the rooms you use most, you don’t need a massive whole-home system.
You need focused, reliable filtration where it actually matters — like your bedroom, nursery, or home office.
The R400 Air Purifier (The Everyday Air Purifier) combines 8 lbs of activated carbon with True HEPA filtration to remove airborne chemicals, odors, and fine particles in contained living spaces.
It’s designed for serious single-room air purification — not oversized claims.
Why You’ll Love The R400 Air Purifier
Real Chemical & Odor Control — Not Just Particle Filtering
With 8 lbs of activated carbon, this unit is built to adsorb airborne chemicals and household odors, not just trap dust.
True HEPA Protection You Can Trust
Captures 99.97% of particles at 0.3 microns, including pollen, pet dander, mold spores, and smoke.
Designed for the Rooms That Matter Most
Powerful 360 CFM airflow makes it ideal for bedrooms, nurseries, offices, and contained living spaces.
Built Without Plastic Off-Gassing
All-metal housing and sealed filtration help ensure you’re not introducing new contaminants into your air.
Straightforward Maintenance, Long Filter Life
Separately replaceable filters with clear lifespan expectations — no surprises, no hidden complexity.
Is the R400 Air Purifier Right for You?
The R400 works best in contained spaces where you want meaningful chemical and particle control up to 1,000 sq ft.
It’s especially well suited for:
✔ Bedrooms – Cleaner air while you sleep, particularly for allergies or pet dander.
✔ Nurseries & Children’s Rooms – Added protection from VOCs and cleaning fumes.
✔ Home Offices – Consistent filtration in the room where you spend most of your day.
✔ Apartments & Condos – Strong standalone purification without central HVAC filtration.
✔ Smaller Living Areas – Dens, studios, and contained spaces.

A stronger option if you’re dealing with persistent odors, renovation off-gassing, or higher sensitivity to airborne chemicals.
