Stop Replacing Filters and Start Cleaning the Air

Many purifiers rely on disposable HEPA filters. These require frequent replacement, contribute to landfill waste, and lose efficiency over time. When not replaced, they can also accumulate gunk and trap bacteria, which can negatively affect the quality of your indoor air.

Washable filters are a better long-term option. Airdog’s TPA® technology replaces the need for standard filters by using reusable collection plates. These plates eliminate and collect even ultrafine pollutants as small as 0.0146 microns.

What’s in Your Air?

Air pollution isn’t always visible, but its impact is real. Irritation, fatigue, and breathing trouble are just a few symptoms of poor indoor air quality. Most air purifiers attempt to address these issues, but they often rely on replacement filters that require constant attention and incur ongoing costs.

Common indoor pollutants include pet dander, human hair, mold spores, pollen, smoke, and chemical fumes. These airborne particles accumulate in living and working spaces, lowering comfort and contributing to health concerns.

While many systems trap some of these contaminants, Airdog takes it a step further. It monitors and removes a broader range of pollutants in real-time, helping to support improved air quality without the hassle of traditional filter maintenance.

Pick the Right Purifier for Your Room

Room size plays a big role in how effectively your air purifier performs. Airdog models are designed to deliver the highest efficiency by optimizing air changes per hour based on square feet coverage. This helps ensure your home's air quality improves in every corner of the room, without requiring extra effort from you.

Small Rooms (under 200 sq ft)

Best for bedrooms, nurseries, or offices. These units offer quiet operation, targeted airflow, and easy maintenance.

Medium Rooms (200–400 sq ft)

Ideal for larger bedrooms or living rooms. They provide better circulation and help manage allergens and everyday airborne particles.

Large Rooms (over 400 sq ft)

Perfect for open spaces, shared family areas, and large living rooms. These purifiers maintain high airflow and clean efficiently without sacrificing performance.

Airdog offers the best air purifier for every room size, keeping your environment cleaner with minimal upkeep and maximum results.

Breathe Different, Live Better

Airdog purifiers are designed for high efficiency and long-term reliability. With washable filters and advanced purification technology, you avoid constant filter replacements and maintain stronger air quality at home.


Most tested air purifiers show a decline in effectiveness as filters clog. Airdog maintains its performance over time. It filters out smaller particles, adapts to your room conditions, and keeps your space cleaner without added waste or upkeep.


Take the next step toward cleaner indoor air. Explore the Airdog collection and choose a purifier that supports your health, your home, and the environment

Let me be the first to tell you that this gadget is amazing! ... I can rest assured knowing that the garbage in the air is ending up on that filter and not lingering around for me to breathe all night. I can report that I've had no sinus infections since owning the Airdog which have plagued my existence. Its impact on my quality of life has been immeasurable."

"We started with the purchase of a X8 Air Purifier for our living area and were amazed with results. We noticed that our allergies became almost non-existent and the normal kitchen odors that used to permeate the house after cooking a meal no longer lingered."

"For the first time in a while, the kids don't wake in the morning all coughs and sneezes. We are no longer taking any allergy medication. ... Thanks to the X8, we are finally dealing with the cause and not just our symptoms."

"This is the best air filter I've had. I'm in love with it. ... Due to cat dandruff, I have a hard time breathing. It is hard for me to sleep at night but since getting the X5, I am sleeping all night now and breathing through my nose again."

"My family is breathing so much better inside now—no more coughing, we sleep better at night, and even the pets seem to be more comfortable now."

"My LIFE depends on this Airdog X3. I am 75 years old and was told I have numerous allergies and would be needing a sleep apnea machine. ... I am allergy- and pill-free, no need for a sleep apnea machine, all my tests are perfect. Most of all, I BREATHE the MOST BEAUTIFUL FRESH AIR possible."

Frequently Asked Questions

How often should I clean the washable filters?

Clean the main filter and the reusable collection plates every few weeks. Airdog purifiers monitor performance and will display a reminder when it’s time to clean. This keeps the air purifier running efficiently without guesswork.

Are Airdog air purifiers safe around children and pets?

Yes. Airdog purifiers are ozone-safe and include features like a child lock. They’re designed for daily use in homes with pets and kids.

Which model is right for my space?

Each model is built for specific room sizes. FitAir works well in small spaces. The X3 is suited for bedrooms, the X5 handles medium rooms, and the X8 supports larger living areas. Every unit balances powerful performance with energy efficiency.

How does Airdog compare to HEPA purifiers?

Many air purifiers use HEPA filters that clog over time and require constant replacement. Airdog uses TPA® technology to destroy smaller particles and maintain a higher clean air delivery rate. No replacement filters are needed.

Do Airdog purifiers release ionized particles?

No. The purifier captures and neutralizes ionized particles before releasing clean air. This keeps your space safe without compromising performance.
