After talking with many of you by instagram and some emails, we see it interesting to make this page to collect somehow the most frequent doubts or questions that you have been sending us.

The first and most asked;

How many times can I use each filter?

We always say between 3 and 7 uses depending on how resinous your mixture is. But the best answer is "up to you", until you don't want to use it anymore, right? There are a lot of/super scrupulous people who use it only once because what they like is its design, its rigidness and how well the smoke flows with slight differences and textures between models. There are people who use a filter "to spend the afternoon" because they like the concept of "the filter of that afternoon", e.g. in my case I use a filter for each workday, there is always one on the table and I use it up to 2 to 4 times that day.

You have also sent us videos of you washing or maintaining them in several different ways that we will explain later on. In that case you have a better answer than JanoFilters can give because, how many times are you going to wash it and how?

From what material are they made of?

100% PLA. An organic polymer, bio compostable and extracted 100% from natural resources; corn starch, potato starch, sugar cane ... We try to constantly communicate and include it in the packaging, yet, this question is still very frequent.

Therefore, to prove that we are not trying to “pull the wool over your eyes / take you for a ride”, down below you’ll find a link where it fully explains the material, the 100% renewable resources through which it’s obtained, its uses in new generation containers and its already established use in medicine in the last 25 years.


From the entire document, we’re sticking with the last sentence of the analysis.

«PLA is a polymer that we will see a lot in the future because it is a true innovation in packaging materials.»

Well, ladies and gentleman, the future is here. And we’ve come to stay.

Here we leave you another link of interest about the assumed danger that comes with the use of common plastics, some general tips to fight against it in our day-to-day consumption and how different and popular the PLA is going to do in the near future:


We encourage you to search as much information as you need, there are thousands of blogs and articles about PLA, but these are the ones that we have found that collect more data that is easy to understand without going into chemistry... 

Hey there, how do I wash/clean them?

The best way we can answer that is: try it and tell us what happened. The purpose was to create a reusable-disposable that has proved to be washable with most of the techniques with which the paraphernalia is washed. Here we detail the ones that we think are more advisable within those that you have sent us these years, (kinda weird yet awesome to say years already hahahah) #thanks

– «I put them in a glass filled with alcohol for 10/15 minutes, gave them a few stirs and then put them down cold tap water. Voilà! As if they were new.».

This is the most used technique to clean all the paraphernalia in general. 

Theoretically, alcohol helps remove oils and resins from the places where it reaches. So that the resin accumulated with the use of the filter can easily leak with a basic wash, we always do our best to design geometries that facilitate the flow of smoke, alcohol, and water. In the case of the Janos, you must keep in mind that they are rigid sponges that absorb everything you throw on them, so be generous with the subsequent water rinse ... After bathing in alcohol, you can start the rinse with a jet of hot tap water directly and finish with cold water. Finally, we would like to note that sun drying is magical so that the smell in the Janos goes away.

– «I rubbed them with a brush soaked with soap and water and they ended up looking impeccable» 

Like everything else in this life, using tools to rub or brush with helps to penetrate more during cleaning. Even if you use organic soap, we recommend a generous rinse with cold water before letting it dry.

Others have put them to rest in hot water or even boiling milk and well… they can resist it, they do. But we don't recommend these techniques. Theoretically, PLA melts from 150ºC, but at 60 / 70ºC it already begins its glass transition, which is basically the transition between solid and liquid where the pieces begin to lose dimensional stability and it is easy for them to deform when removed from the pot hahaha But actually with water, Sun and oxygen are the elements that degrade this material the most. So if we apply this technique very often, it will open the pores of the skin of the material every now and then and the first thing you will see losing/degrading is: the color of the areas where it has been exposed to most heat, and subsequently and with several washes, they will become more weak.

To encourage you to reuse your filters and take them back home to clean them up, we present a range of refillable packagings with holes/windows to aerate them and strategically placed felts to rub off excess resin before putting the used filter back into storage. When we roll directly with a Jano (without using the cigar filter) we recommend removing the filter 2-3mm past the middle of our joint, in order to punish it less and to last us more uses. In the highlights of our instagram profile @janofilters we have the "tips" section with a few videos illustrating these guides to extend the useful life of your Janos 🙂

Besides the online store, is there any outlet where I can buy Janos?

We’re very excited for you to visit this map and even more exiting for us to update it every month, we are no longer only in Spain ^^


Do you make shipments to...?

Yessss! We make express shipments 24/48 working hours to all Peninsular Spain. Outside the Peninsula they do not offer us the same price or the same term, but we can make express shipments to individuals and businesses throughout Europe. For international shipments outside of Europe, better contact by mail to:

 [email protected]

How can we sell your product in our store?

It still makes us very excited every time a Grow or a tobacconist tells us that customers go to them looking for our products / ask about our products. Thank you! We thank you wholeheartedly for your support! If you’re interested on distributing JanoFilters in your business, please get in contact with us through the contact form of our online store or through the mail [email protected] and we will send you the catalog / price list for distributor.

Are they also suitable for tobacco?

For my taste the smoke flows too much for a cigar hahahaha Honestly, they were not conceptualized for tobacco. We present them as a substitute / evolution of the cardboard of a lifetime, a filter of solids that had the highest possible flow rate without entering anything but smoke.

On the other hand, it is true that we have evidence of users who have used them exclusively for their rolling tobacco and say that they love it and that it lasts much longer than the 3 or 7 uses that we always say. Tobacco is not normally resinous, so it actually makes sense that they get less dirty...

How do I choose my ring size?

To measure the diameter of the finger, surround it with a non-elastic string, tightening a little and it should measure between 50 and 75mm. Divide that measurement by 3.14 and you will get the approximate diameter of your finger.

If you are going to buy more than one ring, we recommend buying 2 different sizes, the one you think is in the position of a normal ring and a smaller size for the second phalanx of the finger.

How do you put on/orient the ring so that all the gestures and tricks of the ad come out?

Once you finish rolling the blunt and before lighting it on:

1. Extend the hand with which you are going to wear the ring with the palm of your hand facing you.

2. Put the ring on your index finger and oriented straight in this position, not in the position of a normal ring. By putting it on "this way" you can use your PION more comfortably with your thumb. If you wear it oriented like a common ring there will be several gestures and games that we do not think you will get to hahaha it will be like sucking your elbow.

3. Grab your blunt FROM the Jano or the filter of your cigar with the fingertips of the other hand and go over the PION's tail to the end, if it is a Jano it will make a clack sound hahah if it is a cigar it will simply be hugged in a soft-touch. These 5-10mm that you will use to grasp the filter with your fingertips, will be the 5-10mm of filter that you will be leaving for the lips, do not put it too close because afterwards you will not be able to smoke and you will have to turn the ring over and take it out again hahahah calm down, if it happens to you, sure it will only be once.

4. The logo on the animal's back indicates where we recommend to press with the thumb of THE hand while inserting or removing the Janos with the other hand . If you cannot completely cover the logo with your thumb, the ring is probably not aligned as we had thought.
