It is possible to recognize that the filter has outlived its life by the smell of dust emanating from the device, or by a decrease in the power of the air flow from the filtration system. It is often asked if the HEPA filter can be washed. For most models, washing will be the last event in life - filters are deformed from water and lose their properties.
Can the HEPA filter be cleaned?
It neutralizes odors by trapping microscopic particles of dust and gases from the air. The fact that it can be washed is mentioned in the instructions for the vacuum cleaner or indicated by the letter "W" in the model name. Remember: the HEPA filter is washed under a strong pressure of running cold water without the use of detergents.
Notice that your vacuum cleaner with a HEPA filter is not good at sucking up dust and overheats quickly? It's time to clean it! F.ua will find out if the fine filter can be washed or is it better to immediately replace it with a new one.
Cleaning the HEPA filter
When choosing a vacuum cleaner, pay attention to what material the HEPA filter is made of. Distinguish:
- reusable (washable) - made from fluoroplastic fibers filled with porous activated carbon. It neutralizes odors by trapping microscopic particles of dust and gases from the air. The fact that it can be washed is mentioned in the instructions for the vacuum cleaner or indicated by the letter "W" in the model name. Remember: the HEPA filter is washed under a strong pressure of running cold water without the use of detergents. It is not rubbed with a brush so as not to spoil it. Dry at room temperature. Consider: reusable HEPA filters have a limited shelf life as well as disposable ones, since the pores of activated carbon become saturated and clogged over time. It loses its purifying properties. That is why even a washed filter has a musty smell. The service life of the fine filter is from 1 to 2 years, depending on how often you vacuum;
- replaceable (disposable) - made from layers of paper and fiberglass with antimicrobial impregnation. Do not wash such a filter, as it will immediately deform. It is also useless to clean it by blowing air, since dust microparticles are trapped in the filter fibers and cannot be cleaned. It is better to replace it with a new one immediately.
