Pros of SheMax HEPA filter:

• The folds of the SheMax filter are uniform over the entire surface, dust settles deep into the ribbed surface.
• SheMax filter with the largest area of 245 x 170 mm. This means that it will be able to absorb more dust and last longer.
• The SheMax HEPA filter is protected by a plastic cage in order to avoid damage during cleaning.
• Under high pressure, the dust is pressed and takes the shape of a filter, forming lumps. When removing the filter from the SheMax hood, the dust does not rise up, due to the fact that it is pressed and located at the depth of the finned filter. By shaking out the filter, you don't breathe in the dust.

Even if you are very careful with the SheMax HEPA filter, sooner or later the question of how and when it needs to be cleaned will arise.

Regular cleaning of the filter after each session will ensure a longer service life of the filter. It is advisable to replace the filter every 2/3 months or more often, depending on usage and quality degradation.

HOW TO REPLACE THE FILTER IN YOUR SHEMAX DUST CONTAINER

• Turn off the SheMax dust container Make sure the dust cup is disconnected from the power source.
• Wear protective equipment - a mask and gloves.
• Remove the metal grille, which is fixed to the top of the case with magnets, place it next to it on the table.
• Prepare napkins in advance (preferably wet), unfold on the table. Remove the filter from the top of the housing. Place the dirty part on a napkin. Gently push the edges of the filter to shake the dust onto a napkin. Do not use water or other liquids to clean the filter. Dry cleaning only.
• Turn the cleaned filter over and insert it back into the top of the housing.
• Fold the napkin and dispose of it.
• Place the grille on top of the case on the magnets.
• Turn on the dust container. Only plug the unit into an AC outlet. DO NOT leave the dust container unattended with the power cord plugged into a power outlet. Do not use accessories other than those supplied.
• YOU CAN START WORKING

HEPA filters are fine filters.

The efficiency of fine filters is determined in laboratory tests by the percentage of retained microparticles. For such laboratory tests, an aerosol from a mixture of synthetic microparticles about 0.3 μm (0.1 to 0.5 microns) is used.

HEPA filters most effectively capture microparticles ranging in size from 0.1 μm to 1.0 μm. And larger particles have a negative effect on the characteristics of filters, as they constantly knock down already retained small particles from their places, which leads to a significant decrease in the percentage of filtration efficiency. Also, large particles quickly clog the pores and air channels formed by the HEPA microfibers of the SheMax filter. This results in an increase in the resistance of the airflow filter. Over time, a HEPA-clogged filter severely interferes with the passage of air through the dust collector, causing the suction power of the dust collector to drop sharply and the electric motor to overheat. Therefore, dust particles larger than those for which the HEPA filter is designed (more than 1.0 microns) should not fall on the HEPA filter.
