Our proprietary, patented filter is now biodegradable.  The filter is placed in the interior of the aluminum, reusable case and effectively captures secondhand smoke, pollutants and VOC’s when exhaled into. Keep in mind you can also recycle your box and plant your packaging sleeve. 

The PHREND is approximately 2.5x the width of the POCKET but is the same height as the POCKET – 3.5” tall.

Although the PHREND is not too much bigger than the POCKET, its capacity is 3x the POCKET with up to 500 exhales per filter.

The PHREND works with all your favorite accessories: vaporizers, joints, bongs, dab rigs, even your favorite homemade apple pipe. 

The newly designed mouthpiece and increased size, allows better airflow as well as a quicker, more efficient exhale. 

Simply remove your seed paper sleeve, bury under a thin layer of soil and water occasionally. Flowers should sprout around 4-6 weeks after planting them.

No, the filter cartridge is designed specifically to work inside the reusable case for maximum efficacy. 

No, the PHREND has its own 2-Pack of Refills – link to refills.

Yes, you can wipe the mouthpiece and the reusable case with a wet wipe or damp washcloth with mild soap and water and simply pat dry.

A PHILTER POCKET is nearly 4” in height and around a ½” in width. Small enough to fit in your pocket!

Depending on your lung capacity, you might feel some slight back pressure when exhaling. That is to ensure that our PHILTER captures as much of your emissions as possible including the particulates, pollutants and VOCs commonly found in secondhand smoke and vape.

The POCKET can be used with vape smoke as well as cigarette smoke and cannabis smoke.

No, you should exhale like you normally would. Do not slow your breath down; just ensure you've emptied your lungs before pulling your mouth away from the mouthpiece.

The POCKET is good for up to 150 exhales, depending on your lung capacity, the type of device
you own or the type of smoke you exhale into the filter.

Once it starts to become more difficult or challenging to exhale your vape or smoke back into the POCKET, it’s time to replace the product.

Not right now, but Philter Labs is working on a program to offering recycling at various retail points as well as plans to make the PHILTERS biodegradable in the future.


The PHILTER PHLIP accommodates most popular stick and pen vaporizers including the JUUL, STIIZY, PAX ERA, Rubi by Kandy Pens, G Pen Nova and any 510 thread batteries which fit a universal cartridge.

If you currently have a stick or pen vaporizer, then you won’t need to buy a new vape to use the PHLIP. Your stick or pen vape will fit easily into the PHLIP opening. If you have a vaporizer that is larger or a different shape than a stick or pen, you can purchase a POCKET to use with your current vaporizer or purchase a new vaporizer that will fit into a PHLIP.

The POCKET will need to be changed after 150 exhalations or uses or when it starts to become challenging to exhale your vape back into the POCKET.


The patented filters by PHILTER offer a five-step filtration process that includes proprietary materials meant to reduce odors, absorb and dissolve particulates and/or chemicals commonly found in secondhand vape or smoke and ultimately reduce emissions.

Silicone is a non-toxic polymer mostly made from silica (sand). It can withstand heating and freezing without leaching or off-gassing hazardous chemicals. It is also odor and stain-resistant, hypoallergenic, and because of its smooth surface, very easy to clean. For these reasons, and also because the soft silicone rubber does not break, it is the perfect material for eco-friendly and non-toxic products.

Depending on what type of oil or substrate you are inhaling, you might rarely see a fine mist from the bottom of the filter. Rest assured, your smoke or vapor has been filtered and all you’re seeing is nothing more than the remaining bit of filtered, clean air.
