In HEETS the filter consists of main parts:

• The HEETS filter (the mouth piece) is made of cellulose acetate which is a bioplastic made from modified tree pulp cellulose.
• The cooling plug (otherwise known as PLA filter) is made of modified corn-based material, polylactic acid film.

• The cooling plug otherwise known as PLA filter, is made of bio-based plastic made of corn. More specifically PLA is considered a ‘bioplastic’. According to the European Directive for Single-Use-Plastics, bioplastics are also considered plastics although they are not made of fossil-based polymers as conventional plastics are made of.
• PLA is a biodegradable polymer made from renewable resources such as corn starch, and it is a bioplastic.

• Cellulose acetate as commonly used in filters for tobacco products has the most efficient filtration properties. As material, cellulose acetate is non-toxic, odorless, tasteless, and weakly flammable.
• The cooling plug (otherwise known as PLA filter) is made of modified corn-based material, polylactic acid film, which is also used in the medical, food and beverage industries, e.g. for the production of surgical threads and screws, dental implants or tea bags. The cooling plug is designed to cool down the aerosol generated by the heating tobacco and turn it into an aerosol that is possible to be inhaled.

• No, the plastic in the filter does not melt during consumption. 
• During consumption the temperature inside the filter raises up to a maximum range of 35°C - 40°C depending on the environmental conditions. 
• The temperatures are not high enough to cause the melting of the cellulose acetate 
• The melting temperature of Cellulose acetate is between 230 ° and 300°C

No, we did not change anything in the HEETS stick nor in the HEETS filter. 

• With no fire, no ash, and no need to stub them out, you can simply put used HEETS in the bin and keep litter off the streets.
• You should dispose HEETS sticks in the normal household bin for public waste disposals (mixed waste). Empty HEETS pack, after removing outside foil and inside metallized paper (and putting it in the household bin for public waste disposal), HEETS pack can be put in the paper bin.

For many years, PMI has been actively evaluating alternative filter materials with a lower environmental impact than cellulose acetate (CA). To be acceptable, any new material has to satisfy several criteria, including good filtration efficiency and consistency, significant improvement of biodegradation in different environments, and acceptable taste characteristics. Today, no better alternative to cellulose acetate has been found. We will continue to explore options as new materials and processes become available. 

• The European Union legislator made it a requirement to place such icons on the packs of certain products for single use which contain plastic as to inform adult consumers that such products should not be littered in the environment and should be disposed of correctly in order to protect the environment. The regulation should be valid in all European Union Member States as of July 3rd 2021.
• Philip Morris Polska Distribution Sp. z o.o. comply with the requirements of Directive (EU) 2019/904 (so-called "Single-Use Plastic Directive"), including the marking requirements pursuant to Article 7 of the Directive and Implementing Regulation (EU) 2020/2151 and its corrigendum.

• The regulationshould be valid in all European Union Member States as of July 3rd 2021.

• Products without the new product marking can continue to be sold to consumers without any limitation after July 3rd, 2021, while stocks lasts.

• To comply with the EU Single Use Plastic Directive and to fully support the underlying sustainability program, cleaning sticks have been changed to a paper stem instead of plastic
• As part of the modification, the isopropanol solution was removed to prevent that the paper-based cleaning stick would become soggy.

• To comply with EU Single Use Plastic Directive we reconstructed the IQOS cleaning sticks and use durable paper stem instead of the plastic stick, thus the use stays unchanged. 
• Due to the fact that we removed the cleaning solution from the cotton bud the efficiency is reduced but nevertheless it's inevitable to use IQOS cleaning sticks for a proper cleaning of the IQOS Holder.

It’s not recommended, as by doing so you may damage the IQOS device or potentially cause toxic residues of a solution to migrate into the generated aerosol.

• Yes, you should always continue to clean your device with the IQOS cleaning sticks, as they help to remove tobacco residue on the blade and in the holder.
• To get the best experience, clean your holder with the cleaning sticks and with the IQOS cleaning tool.
• With the IQOS cleaning sticks, unlike other dry cotton sticks, we prevent cotton residues to stay in the holder even if dry.
