Washable Plates
The collecting plates can be rinsed under water and reused, so you aren’t buying new filters every few months. The catalyst filter is the only part that ever needs replacing.
No Ionized Particles in the Air
Charged particles are neutralized on the collecting plates before the air goes back into the room, so nothing ionized is released into the space where you sleep and relax.
Simple Cleaning Reminders
The display shows a “C” in place of the air quality number when the plates need a wash, so there’s no guessing about when to maintain it.

Features
TPA Technology
Instead of a dense filter that clogs and needs replacing, the purifier uses charged plates to pull dust, pollen, and other tiny particles out of the air. The particles stick to the collecting plates, and the cleaned air goes back into the room. TPA is the patented technology AirDog is built around, and it’s the reason the plates can be washed and reused rather than thrown away.
Real-Time Air Quality Display
A built-in display shows the current air quality reading, so you can see what’s in the air at any moment. When you cook, vacuum, or let the dog run through the house, you can watch the number rise and then drop as the purifier works. It also swaps the number for a “C” when the plates need cleaning, so you know exactly when to do it.
Wi-Fi and App Control
Connect the purifier to your home Wi-Fi and use the app to check air quality from your phone. You can see what’s happening in the room without walking over to the unit, which is handy for bedrooms, upstairs spaces, or a nursery where you’d rather not disturb anyone.

What customers are saying
Have two dogs and a toddler, so dust and pet hair are part of daily life. I wasn’t sure a purifier would make a difference, but within a few days the living room felt fresher and the air quality number on the display dropped. The pre-filter catches most of the pet hair, and rinsing the plates is quick. My wife stopped waking up congested, which was the main reason I bought it.

I bought the AirDog for bedroom because the dust was making me stuffy every morning, and my dog doesn’t help. Within a week the air felt different, and I could see the reading on the display drop after I vacuumed. Washing the plates takes a few minutes, and I haven’t had to buy a single replacement filter. I’d tell anyone with pets or allergies to try it.

I work from a home office, and the dust in there was getting out of hand. I set the AirDog on a shelf and mostly forgot about it until the display showed a “C.” I rinsed the plates, let them dry overnight, and it was back to work the next morning. It’s quiet enough that I don’t notice it during calls, and I like that I’m not ordering filters every few months. My allergies have been better since I started running it.
