The Thomas 787276 filter set is designed for all vacuum cleaners featuring the Aqua-Box or Aqua+ system, ensuring your home remains clean and the air stays fresh. This comprehensive kit includes five components: one pleated micro exhaust air filter, two blue foam filters, and two white microfiber filters, which together maintain the efficiency of your appliance. Built from high-quality microfiber and foam rubber, these filters meet the HEPA 13 standard, allowing them to capture 99.99% of dust and 100% of pollen. This makes the set particularly useful for those with allergies who need a high level of air purification during cleaning. To keep the system performing optimally, it is recommended to replace the entire set once a year, while the micro exhaust air filter should be swapped every six months.
