What are the differences between the filtrete filter and polyester filter for the Easy Vac series vacuums?
Answer: The Filtrete filters are a higher quality filter. They have a tighter weave of more material per square inch, plus a very low porosity of that material. This filter will capture fine particles. The Polyester filter is thinner, with less material to capture fine particles but will provide filtration. These are less expensive than the Filtrete filters.
