Frequently Asked Questions
Answers to the most common questions—so you can breathe easy and shop with confidence.
What makes Lichen Air Special?
When it comes to clean air, most air purifiers are underpowered to keep your air clean. Many air purifiers use non-HEPA filters (or make up their own terms for their filters) and don't undergo third-party verification. This means they can basically say whatever they want about their purification. Lichen Air has multiple third-party validation certifications and provides industry-leading power plus the most effective НЕРА filters for removing small particles, HEPA 14. Plus it contains two filters per unit!
What does the Lichen Air purifier remove from the air?
The Lichen Air purifier has been meticulously optimized to remove the most concerning air pollutants for health, particulate matter of 2.5 microns or smaller (PM 2.5). It accomplishes this task using industry leading high efficiency particulate air (HEPA) 14 filters which have been shown to remove up to 99.995% of particles at sizes of 0.3 microns and smaller. This includes mold, bacteria, dust, smoke, pollen, pet hair and other microbes.
Lichen Air features two large HEPA 14 filters which allow it to efficiently purify air in larger spaces and to rapidly and effectively respond to changing air quality demands.
In addition to the HEPA 14 filters, the Lichen Air purifier filters come with corrugated carbon. Carbon helps trap molecules like formaldehyde and other volatile organic compounds (VOCs) as well as odors and gases.
The combination of the Lichen Air purifier's unique filters, coupled with its powerful yet quiet fan system provides an excellent solution to purifying indoor air in bedrooms, offices, and larger spaces to protect and enhance your health for years to come.
Does the Lichen Air purifier produce harmful ozone?
Many air purifiers that use methods like ionization or UV radiation can produce harmful air pollutants like ozone. Lichen Air has been designed and tested to ensure that it does not produce ozone.
How does Lichen Air compare to other purifiers?
Lichen Air was developed to abide by the industry-best quality purification standards. We use HEPA 14 filters and third-party tested filtration, while many other companies make up numbers. You can see our certification on the AHAM website
Does the Lichen Air purifier help with mold?
Mold is a growing issue in indoor spaces. While the Lichen Air purifier can remove mold spores from your air, getting control over the source of mold (e.g., in your walls) should always remain a priority.
How do I install a new filter?
Easy! Simply remove the plate on the top of the unit by pressing down on each side of the top front of the unit, pull the old filters out and replace them with new filters and remove the top plate.
Can I recycle old filters?
At this time, we don't have recycling options available for old filters. But we are looking into this!
What is your return policy?
Lichen Air has a 30-day money back guarantee. If you're not thrilled with the purifier, contact us to return the unit and we'll refund you the purchase price less shipping and handling. Note that the customer is responsible for the return shipping cost.
