Frequently Asked Questions
Breathe easier with answers to your most common questions about clean air.
How do I know which air purifier is right for my room size?
Each product listing includes a recommended square footage. For optimal performance, we suggest choosing a model rated for a slightly larger space than your room to ensure efficient air exchange rates.
How often do I need to replace the HEPA filters?
Most HEPA filters last between 6 to 12 months depending on usage and air quality. Many of our models feature a filter replacement indicator light to notify you when it is time for a fresh one.
Do you offer free shipping on large units?
Yes, we offer free standard ground shipping on all orders over $99 within the contiguous United States. Larger units are securely packaged to ensure they arrive in perfect condition.
What is your return policy if I am not satisfied?
We offer a 30-day risk-free trial. If you are not satisfied with your air purifier, you can return it within 30 days of delivery for a full refund, provided it is in its original packaging.
Are your air purifiers effective against pet dander and odors?
Absolutely. Our purifiers equipped with True HEPA filters capture 99.97% of airborne particles like dander, while our activated carbon filters are specifically designed to neutralize household odors and VOCs.
Do the units come with a manufacturer warranty?
Yes, all products sold at The Air Purifier Store come with a minimum 1-year manufacturer warranty covering parts and labor. Some premium brands offer extended coverage up to 5 years.
