Our 1st biodegradable filter cartridge available as a 2-pack!
Made specifically for the PHREND, these filters eliminate secondhand smoke and smell for discerning users who prefer traditional methods.
Plus, you can breathe easy knowing that the biodegradable cartridge you dispose of will not add to the growing pile of plastics plaguing our landfills and ecosystems for decades to come: it will biodegrade in under 3 years!
There is a difference between biodegradable packaging and compostable packaging. Biodegradable simply means a material breaks down into the ground. Compostable materials also break down, but they add nutrients to the soil too, which enriches it. Compostable materials also disintegrate at a naturally faster rate. If you’re not able to compost your packaging, simply toss it into your regular trash can. As noted, it will quickly biodegrade in your local landfill.

Nothing changes about your routine. PHREND works around your lifestyle.
Put PHREND to your lips and exhale directly through it. The Zero-5™ filter traps particulates and odor before they ever hit the air.
What comes out the other side is clean, filtered air. No visible cloud, no lingering odor. Just discretion.
Five stages of microfiltration. One result: nothing in the air but the moment.
Proprietary airflow reduces back pressure, letting you exhale naturally without the "blocked straw" resistance of most filters.
Medical-grade HEPA filtration layers trap and remove toxic particulates including carcinogens, viruses, and bacteria.
Specialized media scrubs Volatile Organic Compounds (VOCs) to eliminate lingering odors and airborne irritants.
The result? A completely invisible, odorless output that respects the air you share with friends, family, and pets.
Lab-tested filtration efficiency. No false claims, just results.

Works well inside the house. My mom can’t be around strong smells and this really cleans the smoke.
