From the makers of PhoneSoap — over 2 million sanitizers sold, trusted for 10+ years.
The air purifier for large rooms — up to 1,600 sq ft
A large room needs more than a desktop purifier. The AirSoap X5 circulates and purifies air across up to 1,600 square feet — an entire open-concept main floor: the kitchen, the dining area, and the family room, covered by a single unit. It's the same washable TPA technology as the AirSoap X3, powered by Airdog, scaled up for the big, open spaces where your family actually spends time. And because the filter is washable, covering more space never means more filter refills.
Looking for a whole-house air purifier? One AirSoap X5 covers a large open floor rather than an entire multi-level home through the ductwork. For whole-home coverage, the simplest approach is one unit per level or large zone — each running the same filterless TPA, with no filters to buy for any of them. It's a practical way to get whole-house clean air without a ducted HVAC installation.
How the AirSoap X5 cleans the air
The AirSoap X5, powered by Airdog, runs the same filterless TPA (Two-Pole Active) technology as the X3. Instead of trapping particles in a disposable HEPA filter, it charges and neutralizes them, then collects them on washable plates — capturing particles down to 14.6 nm, far smaller than HEPA's ~300 nm limit. It cleans by destruction, not just collection.
HEPA catches everything down to about 300 nm — dust, bacteria, even cigarette smoke. But finer wildfire smoke, influenza, coronavirus, and rhinovirus slip right through. AirSoap's TPA captures everything HEPA does — and more, down to 14.6 nm.
Built for the air your home actually has
Odors, dander, smoke, pollen, mold, germs — the X5 goes after the things you notice and the things you can't see.
Odors & Smells
The catalytic stage breaks down cooking smells, bathroom odors, and stale air at the molecular level — not a fragrance mask, actual removal.
Pets & Dander
Pet dander and hair are some of the most persistent indoor allergens. The pre-screen grabs hair while TPA captures the fine dander floating at nose height. Got pets? See our air purifier for pets guide.
Smoke & Wildfire
Wildfire haze and cigarette smoke are ultrafine — far below HEPA's floor. TPA charges and collects particles down to 14.6 nm, where smoke actually lives.
Allergies & Pollen
Pollen, dust mites, and seasonal allergens get charged and pulled from the air you breathe — independently lab-tested for allergen removal. Fighting allergies? See our air purifier for allergies guide.
Mold & Spores
Mold spores don't just get trapped where they can keep growing — TPA's ionic field inactivates them, so they're neutralized, not stored in a filter. See AirSoap as an air purifier for mold →
Viruses & Sickness
Tested to destroy 99.9% of germs† and shown effective against airborne viruses — inactivating them in the ionic field instead of letting them survive in a filter.
Clean air that fits the room
Quiet enough for the bedroom, powerful enough for the living room — the X5 disappears into your space and just works.
Smart where it counts, simple to live with
Everything on the X5 earns its place — real sensing, real airflow, and zero ongoing filter costs.
Real-time AQI sensor
Auto mode reads your air quality and adjusts fan speed on its own to keep it clean and efficient.
Sleep mode
Runs about 30 dB on its low setting and dims its lights for restful, quiet nights in large rooms.
Washable plates, forever
Rinse the collecting plates in the sink and reuse them for years. No subscriptions, no replacements, no landfill.
360° airflow + 210 CFM
A 360-degree intake and 210 CFM clean-air delivery move far more air than the X3 — built for large, open spaces up to 1,600 sq ft.
Whisper-quiet by design
With no dense HEPA filter choking airflow, the fan moves more air while spinning slower — and quieter — than comparable filter purifiers.
Energy efficient
Just ~40 W at full speed — still a fraction of the energy of forcing air through a dense HEPA filter.
Plates that are washable
Once every three months — instead of buying new HEPA filters — just rinse your collection plates and slide them back in. That’s the whole maintenance routine.
- About 5 minutes, roughly once every 3 months
- Just water — a little mild soap for stubborn buildup
- Reuse for years — $0 spent on replacement filters
AirSoap X5 specs
The AirSoap X5 is rated for up to 1,600 sq ft, the standard coverage figure measured at one air change per hour — the same way virtually every US air purifier rates its coverage. For faster, more frequent purification we recommend 404–540 sq ft, where the X5 cycles the whole room's air about four times an hour.
Smaller space? The AirSoap X3 filterless air purifier runs the same TPA tech for rooms up to 860 sq ft. Or compare all AirSoap filterless air purifiers and see how TPA works on our technology page.
Frequently asked questions
What size room does the AirSoap X5 cover?+
Up to 1,600 sq ft at one air change per hour - a full open-concept main floor. For faster, more frequent purification we recommend 404-540 sq ft, where it cycles the room's air about four times an hour.
Is the AirSoap X5 a good air purifier for a large room?+
One X5 covers a large open floor, not an entire multi-level home through ductwork. For whole-house coverage, run one unit per level or large zone - each filterless, with no replacement filters to buy. It's a practical whole-home approach without an HVAC install.
Does the AirSoap X5 use replacement filters?+
No. The TPA filter is washable - you rinse the collecting plates and reuse them, so there are no replacement filters to buy and no refill costs, ever. Covering a larger room never means buying more filters.
How is the X5 different from a HEPA air purifier?+
Instead of trapping particles in a disposable HEPA filter, the X5's TPA technology charges and captures particles on washable plates - down to 0.0146 microns, roughly 10-20x smaller than HEPA's limit. So it captures finer particles than HEPA and never needs a filter replacement.
How loud is the AirSoap X5?+
From about 22 dB on its lowest setting - quieter than a whisper - up to roughly 57 dB at the highest speed. That makes it quiet enough for a bedroom or living room even while it's clearing a large space.
What's the difference between the AirSoap X3 and X5?+
They share the same filterless TPA technology and washable plates. The X5 has higher capacity - a 210 CFM CADR versus the X3's 120 CFM - so it's sized for larger rooms up to 1,600 sq ft. For rooms up to 860 sq ft, the AirSoap X3 is the right fit.
What's the best air purifier for large rooms?+
For large open spaces up to 1,600 sq ft, the AirSoap X5 pairs high 210 CFM airflow with washable-plate TPA technology, so covering more space never means more filter costs. For rooms up to 860 sq ft, the AirSoap X3 runs the same technology.
