Discretion With Every Exhale
Introducing the PHREND! The newest addition to the PHILTER Phamily and our 1st product featuring a biodegradable filter.
Made of plant-based polymer, this filter will decompose in less than 3 years compared to nearly a thousand for regular plastic!
The PHREND is made for discerning users! Built for heavy exhales! A newly designed mouthpiece allows for a quicker, more efficient exhale and the increased capacity means you can get up to 500 exhales per filter – that’s 3x the capacity of the POCKET.
It was also made to protect Mother Earth and give back to nature. Each PHREND product includes a packaging sleeve made of biodegradable, eco-friendly seed paper. When the paper is planted, the seeds grow into wildflowers and the paper composts away.
Phrend-ly to you, those around you and Mother Earth!

ENGINEERED TO FIT YOUR LIFE
Handheld peace of mind, with clinical-grade filtering performance.

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.

ZERO-5™ TECHNOLOGY
Proprietary airflow reduces back pressure, letting you exhale naturally without the "blocked straw" resistance of most filters.





Lab-tested filtration efficiency. No false claims, just results.
Captures particles down to 0.3 microns. That's 300x smaller than a hair.
No visible exhale. No lingering smell. No awkward conversations.
My apartment doesn't smell anymore. Roommates had no idea I was even home.
Honestly didn't think it would work this well. Blew right into it and nothing came out the other side. Sold.
Small enough to keep in my pocket. I just exhale through it and that's it. No odor, no mess, no drama.

Proprietary Zero-5™
Honest claims only
You exhale directly into the device. Inside is our patented Zero-5™ technology — a 5-stage microfiltration system that captures airborne particulates, odor, and toxins as you blow through it. What comes out the other side is clean, filtered air, trapping particles as small as 0.3 microns with 99.75% efficiency.
Each device is built for hundreds of exhales under normal conditions. Usage varies with the duration and intensity of each exhale. When the filter is spent, drop in a fresh replacement cartridge and carry on.
The device itself is durable and long-lasting. When the filter is exhausted you simply swap in a replacement refill to keep using it — no need to buy a whole new unit.
The filter cartridge is designed to decompose. Pop out the spent cartridge and dispose of it responsibly — 100% of PHILTER packaging is biodegradable, recyclable, or reusable.

Works so well. Able to clear the smoke out
You can literally use this in public restrooms or indoors...almost zero smoke so long as you blow right. Fits in purse. Gamechanger.
