3.         Charge the battery by using 5V/1A cord and within the temperature range of 50°F to 104°F. Charging outside this range may shorten battery life, extend charging time, or stop charging for safety reasons.

4.         Do not overcharge or over discharge the battery. If unused for long periods, charge and discharge it every three months to maintain battery health.

5.         If the battery is obviously swollen or abnormally hot, stop using it. If the above-mentioned abnormal condition continues, please contact the manufacturer.

Respirator inspection

1.    Check for cracks, damage, or dirt on the respirator. Ensure that the respirator, especially the areas in contact with the face, is not deformed. The material should be soft, not stiff.

2.    Inspect the inhale valve for any signs of warping, cracking, or damage. Lift the valve flap and check the valve seat for dirt or cracks. Similarly, check the exhale valve and replace them if necessary.

3.    Ensure the head strap is intact and has good elasticity. Replace it if needed.

4.    Check that the gasket is properly installed and free from damage or dirt. Replace it if necessary.

5.    Inspect the purifier cartridge, filter cover and filters for any damage, cracks, or dirt.
