02 \\ DETAILLED USE

FOREWORD

Please make sure the instructions which follow are fully respected in order to ensure an optimal use and duration of your PRECIMASK® AIR. Under no

circumstances will the manufacturer and/or the suppliers be held responsible for any damage as a result of improper use of the mask.

1// Before putting on PRECIMASK® AIR, wash your hands with soap and water or with a hydro-alcoholic solution. It is strongly recommended to wear PRECIMASK® AIR

on clean skin, avoiding contact with facial hair.

2// To place PRECIMASK® AIR on your face, hold the rigid part of PRECIMASK® AIR with one hand and the strap with the other hand.

Position the mask on your face and pass the strap either on the top of your head or behind the neck.

Once the PRECIMASK® AIR is on your face, make sure that the silicone face seal is in contact with the area between your nose and your chin.

3// The PRECIMASK® AIR is delivered with two dierent straps.

By defaut, the mask is mounted with the wide strap (suitable for long hair in particular). It can be adjusted to the desired length by pulling on

the two ends. Once the setting is obtained, you can cut o the protruding ends.

A second strap is provided, equipped with a Stop Cordon. Once positioned, then you can adjust this strap by pressing the push button of the

Stop Cordon.

The two straps can be placed on the top of the head or on the neck.

4// To remove your PRECIMASK® AIR, wash your hands with soap and water or with a hydro-alcoholic solution. Then take the mask in your hands, move it away from

your face and slide it over your head: the straps are ﬂexible enough, it is not necessary to touch the Stop Cordon and thus you retain your individual settings.

You can use the pouch (delivered with the mask) to protect it, while waiting to wash it, or whilst transporting it. To avoid any contamination of the pouch, it will be

necessary to wash it in hot soapy water regularly.

5// Finally, wash your hands again with soap and water or an alcohol-based hand rub.

It is recommended that you do not wear the mask for more than 4 hours continuously. Take a break in the middle of the day and store your mask in the pouch provided

for this purpose. It is not necessary to wash it after 4 hours.

suitable for long hair

WARNING

As the mask is particularly airtight, condensation forms inside the mask, causing the silicone to fog and droplets to appear inside the mask.

These droplets are collected in a cavity inside the mask, and do not aect the wearer in any way. Condensation is a natural phenomenon that cannot be

avoided and you just need to wipe the mask regularly.

Type 2 cleaning : Simple monthly regeneration of ﬁltration cartridges

Once a month or after storage for more than 4 weeks, it is recomended to soak the

PRECIMASK® AIR ﬁltration cartridges in boiling water for 30 minutes. Then, dry in the oven

at 110°C (230°F) for 1 hour.

WARNING | Handle the ﬁltration cartridges with care when they come out of the oven so

as not to burn yourself and wait for them to cool completely before putting them back on

the mask.

03 \\ MAINTENANCE AND CLEANING

PRECIMASK® AIR is a cleanable and durable face mask, the cleaning protocols are broken

down into several types : Type 1 for daily sanitization of the mask, Type 2 for the simple

regeneration of the ﬁltration cartridges once a month and Type 3 for enhanced regeneration

of the ﬁltration cartridges in case of clogging (cannot be regenerated using Cleaning Type 2).

Regeneration protocols (Type 2 & 3) allow the ceramic to be thoroughly cleaned.

Please remove the ﬁltration cartridges before washing the mask. To do this, unclip the

ﬁltration cartridges by pushing them with your thumb towards the inside of the mask by

small successive pressures.

Type 1 cleaning : Daily disinfection of PRECIMASK® AIR

This cleaning is recommended after a day of wearing the mask to ensure viral inactivation

and to properly dry the cartridges, especially if the mask is used in a humid environment.

Place the ﬁlter cartridges in your oven at 90°C (200°F) for 10 minutes. The rest of the mask

should be washed with hot soapy water, or with a virucidal cleaning solution.

If you wear the mask in a humid environment, or if you feel decreased breathability, it is

possible to increase the oven temperature to 110°C (230°F) for 10 minutes in order to dry

the ﬁlter cartridges.

If you have chosen the wide strap (without Stop Cordon), you can put the entire mask in the

oven at 90°C (200°F) for 10 minutes.

WARNING | Do not put the Stop Cordon in the oven as it could deteriorate.

IMPORTANTE CLEANING INFORMATION

It is recommended to sanitize PRECIMASK® AIR daily and to thoroughly clean

(simple regeneration) the ﬁlter cartridges once a month, scrupulously following

the procedures described above.

Do not dismantle the integration capsules of the ﬁlters which protect the ceramic.

These must remain sealed to ensure their eectiveness.

Avoid contact of PRECIMASK® AIR and ﬁlters with liquids other than those

recommended for cleaning.

04 \\ PRECAUTIONS FOR USE

PRECIMASK® AIR has been designed to protect its wearer and its environment from most

particles and aerosols (spray, sneezing, etc.) of 3 µm, except in extreme atmospheric

conditions.

WARNING !

Continuously check that the PRECIMASK® AIR is properly adjusted, covers your mouth and

your nose and that the ﬁlter cartridges are correctly ﬁtted.

The use of PRECIMASK® AIR does not replace barrier gestures (regular hand washing, social

distancing & reduction of contact with other people). It adds an eective and scientiﬁcally

proven physical barrier so that you can enjoy social relationships with less risk of exposure.

If your PRECIMASK® AIR is not to be used for a long time, clean the cartridges before storage

: Type 1 cleaning for storage expected for less than one month, and Type 2 cleaning for

expected storage for more than 1 month. Then put the mask back in its original packaging

and store it in a dry place not exposed to light. If you must use your mask after more than

1 month of storage, do a Type 2 cleanse again.

Store it away from moisture, at a temperature between -5°C (25°F) and +55°C (130°F).

Avoid any environment that is dusty or that may cause water condensation inside the

ﬁlters.

INSTRUCTIONS FOR USE

Handle your PRECIMASK® AIR with the greatest care, avoid mechanical shocks

and falls.

Wash your hands with soap or hydro-alcoholic gel before handling the mask or

its various parts.

Never dismantle the integration capsules, their role is to protect the integrity of

the ﬁltration medium.

The components of PRECIMASK® AIR including the ﬁlters have been designed to be reused

over a long time span. If you strictly follow our recommendations, the mask will maintain

its protection level for a long time.

05 \\ WARNING

• THE CHARACTERISTICS OF THE MASK AND IN PARTICULAR ITS FILTERING EFFICIENCY MAY BE AFFECTED IN CASE OF A FALL OR SHOCK. In particular, a deformation of the ﬁltration cartridge

after a drop or impact renders the ﬁlter unusable as it is. You can order new cartridges on our website precimask.fr. The recycling of damaged cartridges is taken care of by PRECIMASK® by

returning them to us at the following address : Pracartis Groupe - Chemin de la Forêt - 74250 PEILLONNEX - France

• A damaged cartridge must be replaced.

• Filters or any other part of PRECIMASK® AIR must not be modiﬁed by any mechanical, chemical and / or thermal process.

• Make sure that there is no hair between the PRECIMASK® AIR seal and your face. The tightness of PRECIMASK® AIR can also be compromised by moustache and thick beards.

Type 3 cleaning : Enhanced regeneration of ﬁltration cartridges

This step is to be applied in case the ﬁltration cartridges become clogged for example by

dust :

• Soak them completely in 1 liter of a mixture of 3/4 ofwater and 1/4 of white vinegar

8 ° and boil the solution for 30 minutes.

• Drain the cartridges and then let them cool down.

• Rinse them with clean water for 10 seconds.

• Repeat a full Type 2 cleaning (see above).

To reassemble the cartridge on the mask, place it inside the mask with the rounded side

towards the opening. Press gently on the cartridge edge until it is correctly positioned (The

ﬂat part inside the mask should rest on the silicone rim of the capsule housing).
