The air purifier for your baby's nursery
Babies breathe faster than adults and spend most of the day in one room — so nursery air matters. AirSoap runs quietly on washable plates, adds no chemicals or fragrance to the room, and is CARB-certified for California's strict ozone-emission limits.
Do babies need an air purifier?
Need is a strong word — plenty of babies do fine without one. But the case for a nursery is straightforward: infants breathe more air per pound of body weight than adults, their lungs are still developing, and they spend the majority of a day in a single room. Whatever is in that room's air, they get more of it.
A purifier reduces what is floating in that room — dust, dander, pollen tracked in from outside, smoke that drifts indoors. AirSoap's TPA (Two-Pole Active) technology captures particles down to 0.0146 microns, about 20× finer than a HEPA filter, and does it on washable plates rather than a disposable filter you keep rebuying through the newborn years.
Is an air purifier safe for a baby's room?
The honest concern with any charged-plate or ionizing purifier is ozone, which is a lung irritant. Here is exactly where AirSoap stands.
CARB-certified for California's ozone limits
AirSoap is certified under the California Air Resources Board Executive Order for electronic air cleaners — the standard that caps ozone emissions. It cleans using charged, washable collection plates rather than by releasing ozone into the room, and it adds no chemicals, sprays, or fragrance to the air your baby breathes. If you have any concern specific to your child's health, talk to your pediatrician.
Leave it running overnight
An air purifier only helps if it is actually on. AirSoap runs quietly enough at low speed to leave on through naps and overnight, so the room keeps clearing while your baby sleeps rather than only when you remember to switch it on.
No sprays, no fragrance, no refills
AirSoap works mechanically — it charges particles and collects them on plates you rinse in the sink. There is no scented cartridge, no chemical additive, and no disposable filter to replace on a schedule during the most expensive year of your life.
What it removes from the room
Independent laboratory testing of AirSoap's TPA technology against common indoor airborne particles and pathogens.
| Airborne pollutant / pathogen | Result |
|---|---|
| Influenza virus (H3N2), 1 hr | 99.9% |
| SARS-CoV-2, 30 sec | 99.02% |
| Dust-mite allergens | >99.9% |
| Airborne mold | 99.8% |
| Airborne bacteria (2 hr) | >92% |
| Fine particles (PM2.5) | 99% |
| Particles down to 0.0146µm | >99.9% |

Why filterless makes sense in a nursery
A nursery purifier runs almost continuously for years. That is exactly the use case where replacement filters add up.
A filter bill that never ends
Running a HEPA purifier around the clock loads the filter faster, so replacements come more often — and a neglected, loaded filter quietly moves less air. In a room you are running continuously from newborn through toddler, that is a recurring cost and a recurring chore.
Rinse the plates, put them back
AirSoap collects everything on washable plates. When they load up you rinse them in the sink and slide them back in — performance resets instead of degrading, and there is no filter to buy again. It also captures particles ~20× finer than HEPA, down to 0.0146 microns.
Quiet, chemical-free, and always on
Quiet on low
Runs quietly enough at low speed to stay on through naps and overnight — it's a genuinely quiet air purifier because there's no HEPA filter for the fan to fight.
Nothing added
No sprays, no scented cartridges, no chemical additives. It charges particles and collects them on plates — and it is CARB-certified for California's ozone-emission limits.
No filters, ever
Washable plates instead of disposables. Rinse and reuse, with no replacement filters to budget for through the newborn and toddler years.
A few feet from the crib, not right beside it
Place AirSoap a few feet away from the crib with clear space around the intake and outlet, and out of reach as your baby starts pulling up. Run it continuously on a low speed rather than in bursts — steady airflow does more than an occasional blast, and it stays quiet.
