Frequently Asked Questions
Everything you need to know about breathing cleaner air.
How often should I replace the filters in my air purifier?
For optimal performance, we recommend replacing HEPA filters every 6 to 12 months and carbon filters every 3 to 6 months, depending on usage and air quality levels in your home.
Do you offer free shipping on air purification systems?
Yes, we offer free standard shipping on all orders over $99 within the contiguous United States. Expedited shipping options are available at checkout for an additional fee.
What is your return policy if I am not satisfied?
We offer a 30-day risk-free trial. If you are not completely satisfied with your purchase, you can return the unit in its original packaging for a full refund, minus return shipping costs.
Are your air purifiers effective against pet dander and odors?
Absolutely. Our units equipped with True HEPA filters capture 99.97% of airborne particles including pet dander, while our activated carbon filters are specifically designed to neutralize household odors.
Do the products come with a manufacturer warranty?
Yes, all air purifiers sold at The Air Purifier Store come with a minimum 1-year manufacturer warranty covering parts and labor. Some premium brands offer extended warranties up to 5 years.
How do I know which size purifier is right for my room?
Each product page lists the recommended square footage. As a general rule, we suggest choosing a model rated for a slightly larger space than your room to ensure a higher Clean Air Delivery Rate (CADR).
