Why it is important to filter the ultra fine particles?
Ultra fine particles are small enough to stay suspended in the air and be inhaled more easily. Filtering them helps reduce exposure to airborne irritants that can affect breathing comfort and overall air quality.
Does owning an Airdog require any maintenance fees?
No. Airdog uses washable, reusable components instead of disposable HEPA filters, keeping maintenance costs low.
How often should I clean the filters?
Cleaning frequency depends on air quality and daily usage. Most users clean the collection plates periodically to maintain optimal performance.
