Pre-Filter Cotton

Pre-Filter Cotton is used as the first line of defense in a multi-stage filtration system. Its primary purpose is to capture larger particles such as dust, hair, and debris before they reach the finer filters, such as HEPA or activated carbon filters. This helps to extend the life and maintain the efficiency of the subsequent filters by preventing them from becoming clogged with larger particles.

The replacement frequency for Pre-Filter Cotton depends on the intensity and environment of use. Typically, it should be replaced every 2-3 months to maintain optimal filtration efficiency. However, in environments with high levels of dust or particulates, more frequent replacement may be necessary. Regular inspection of the pre-filter is recommended to determine if it appears dirty or clogged, indicating a need for replacement.

While some types of Pre-Filter Cotton can be gently cleaned and reused, it's generally recommended to replace them with new ones to ensure maximum filtration efficiency. If cleaning is an option, it should be done carefully by shaking off loose dust or gently washing and completely drying the pre-filter before reinserting it into the filtration system. Reusing pre-filter cotton beyond its effective lifespan can compromise the performance of the entire filtration system.
