Safety Precautions

Health Considerations when Using Airofit Essential
To prevent damage to your Airofit Essential or injury to yourself, read the following precautions in their entirety before using the Airofit system.

• To prevent the potential transmission of infections, we recommend that you do not share your Airofit Essential with any other user, including family members. Moreover, your Airofit Essential is calibrated for only one user’s personalized data.
• The Airofit Essential is manufactured in a safe environment. However, the Airofit Essential is not provided as a sterile device – we recommend that you clean the Breathing Trainer prior to use.
• Do not use Airofit Essential while performing any other activities (e.g., running, cycling, rowing, driving).
• Do not use Airofit Essential for more than 60 minutes per day.
• Respiratory training can cause dizziness. We recommend that you remain seated after training and breathe normally for a minimum of 1-2 minutes before moving on to other activities.
• The Airofit Essential is suitable for ages 12 and over. Users under the age of 15 should only use Airofit under the supervision of an adult.
• Immediately stop the exercise if you feel any physical discomfort.
• If you feel light-headed or dizzy while exercising with Airofit, you should stop and check the resistance wheel’s inspiratory and expiratory settings.
• If you are suffering from a cold, sinusitis, or other respiratory tract infection, we advise you to wait until all symptoms have disappeared before using the Airofit Essential
• If you have any medical conditions with your respiratory system, heart, or blood pressure, we recommend that you consult a doctor before using Airofit.
• Do not use Airofit to inhale any type of substance.

Contraindications
To prevent damage to your Airofit Essential or injury to yourself, read the following precautions in their entirety before using the Airofit system. Use appropriate caution in the following situations:

• A history of spontaneous pneumothorax (collapsed lung), i.e., not due to traumatic injury.
• A traumatic pneumothorax that has not fully healed.
• A burst eardrum that has not healed fully, or other conditions of the eardrum.
• The subgroup of asthma patients with unstable asthma with abnormally low perception of dyspnea (shortness of breath) are also unsuitable candidates for Inspiratory Muscle Training (IMT).

General Safety Cautions

• Only use the Airofit Essential together with the Airofit mobile application and the selected sessions and programs. Always set resistance to the recommended settings.
• Do not drop your Airofit Essential. Dropping the Breathing Trainer may result in malfunction or cause a decline in performance.
• Ensure that the inhale/exhale vents located on the sides of Airofit Essential are not obstructed while training.
• Do not immerse the E-Unit, or expose it to jets of water, or any other liquids. For cleaning instructions, refer to the Maintenance section.
• Never use scouring pads, abrasive cleaning agents, or aggressive liquids such as petrol or acetone to clean the device. The Airofit Essential is not dishwasher or autoclave safe. For cleaning instructions, refer to the Maintenance section.
• Ensure that your Airofit Essential remains hygienic and in good working order. Always make sure that your device is dry before storing it. We advise you to store your Airofit Essential in a suitable, clean, and hygienic way.
• Only use the supplied magnetic charging cable together with a CE-certified USB charger (refer to Technical Specifications).
• If you have more than one Airofit Essential, do not swap the E-Units. Each E-Unit is calibrated precisely to the device, and swapping them will cause inconsistencies in measurement results

Operation

• Airofit Essential
• Magnetic charging cable
• Airofit Essential Start Guide

Airofit Essential System Description
The Airofit PRO 2.0 system consists of the Airofit Essential and the Airofit mobile application. The Breathing Trainer provides resistance to your inspiratory and expiratory breathing, while the application provides guidance to respiratory training and monitors your performance over time.

Getting to Know the Airofit Essential

• A Power Button
• B Removable E-Unit
• C Inspiratory Resistance Wheel
• D Expiratory Resistance Wheel
• E Trainer Unit
• F Removable Mouthpiece

Using the Airofit Correctly

• When using the Airofit Essential, you should be relaxed and sitting upright.
• Keep your head facing straight forward, as looking down can cause more salivation. Do not hold the Airofit Essential with your hand during training unless absolutely necessary.
• If you must, hold it with your hand on the E-Unit and make sure that the openings near the resistance wheels are not obstructed.
• Place the device in your mouth so that your lips cover the outer shield of the Mouthpiece and make a complete seal.
• The Mouthpiece bite block should be gripped between your teeth.
• When starting the exercise, the Breathing Trainer requires a short calibration (zeroing) of the pressure measurement. Do not breathe into the Trainer during this process. Wait for the instructions to begin the respiration exercise.
• Airofit Essential should not be used in conjunction with other physical activities. Breathing training while performing other physical exercises will compromise the oxygenation of the locomotor muscles

Maintenance

Always make sure that your device is dry before storing it. We advise you to store your Airofit Essential in a suitable, clean, and hygienic way. Fully charge your device if you are storing it for more than a week without use to avoid full battery depletion. Remember to charge the Airofit Essential fully before resuming usage. (Youtube: Airofit PRO – Care and Maintenance)

Daily Maintenance
As the device will be exposed to saliva during use, it is important to clean it frequently. We recommend cleaning your device after each training session. Always remove the E-Unit before cleaning the device. Do not immerse the EUnit, or expose it to jets of water, or any other liquids. We recommend washing the Trainer Unit and the Mouthpiece in warm water (below 60°C). After washing, shake off and blow through the Trainer Unit to remove excess water, making sure it’s completely dry before reassembling. The Airofit Essential is not autoclave or dishwasher safe.

Weekly Maintenance
Once a week, use a drop of dish soap in water to wash your Trainer Unit and Mouthpiece thoroughly. Once washed, hold the Trainer Unit under running water, allowing it to run through. Shake off excess water, blow through the Trainer Unit, and dry with a clean towel. Let it air dry. Make sure the device is completely dry before reassembling.

Monthly Maintenance
Charge your Airofit Essential fully at least once a month, even when not in use, to avoid complete battery depletion.

Getting Started with Airofit Essential

First-time use essentials
Before you start your training, it is recommended to charge the E-Unit until the light is solid green. While the E-Unit is charging, rinse the Trainer Unit and Mouthpiece in warm water, wipe them with a clean towel, and let them air dry. When the E-Unit is fully charged and the Trainer Unit and Mouthpiece are completely dry, you can reassemble the Breathing Trainer. The E-Unit contains electronics; do not immerse the E-Unit, or expose it to jets of water, or any other liquids.

Sign-up procedure
The Airofit app will guide you through the initial steps of your Airofit journey.

Lung Test
As instructed in the Airofit app, you will initially perform a lung test to establish your breathing condition. The app notification will pop up when you should take the lung test.
The lung test records your

• Accessible Lung Capacity, your active lung volume
• Inhale strength, your Maximal Inspiratory Pressure (MIP)
• Exhale strength, your Maximal Expiratory Pressure (MEP)

These measures are evaluated based on your gender, age, and height (as set in your profile). The percentages (0-200%) show how you compare to other users in the same demographic group as you.

Start Training
Based on the goal selected in the Airofit app, you will find training recommendations within the app. Prepare your trainer by setting the correct resistance levels and follow the app guidance to start the training. When your exercise is finished, the result screen will appear in the app, and you will see a summary of your training.

Understanding training levels

• Beginner: Low pressure loads with short breathing cycles
• Intermediate: Medium pressure loads with medium breathing cycles
• Expert: High pressure loads with long breathing cycles

Understanding training duration
Training duration can vary between 1-10 minutes. We strongly recommend that you always take a short break after every 3 minutes of training.

Training History
The app contains your training history so that you can access your lung test and training session results at any time.

Settings
You can update your profile in the settings. Your account is protected by a password, which can be reset. Preferences for background music and guidance sound can be turned on/off for your training exercise. If you have any questions about training, you can get them answered by clicking on the FAQ button. You can also report a problem if you find something wrong with the app. The app also contains the Terms and Conditions (requires internet connection) and thePrivacy Policy, which you agreed to when you created your account.
