Filtrete™ Air filters can help remove the top 8 allergens from your home

Will a Filtrete™ Filter eliminate the need for dusting?

Atmospheric dust consists of a wide variety of particulates ranging in size from 0.001 micron to a relatively large 100 microns. Because of the weight of the large particles, they will settle on your furniture long before they could reach your filter. The filter will capture some dust, but it will not eliminate the need for dusting.

Replacing Your Filter

For maximum effectiveness, we recommend you change your filter at least once every three months. You may want to change the filter more frequently if:

- You are remodeling or there is any other kind of construction work in progress

- There is any furniture or drywall sanding in process

- You own pets

- Anyone in the home smokes

- There is a fan running continuously

Now that you know how to change a Filtrete™ Air Filter, don't forget to change it every 3 months

Expensive washable/reusable filters can't capture microparticles as well as electrostatic Filtrete™ Filters can. The positive and negative charges on the fibres help pull more particles from the air passing through the filter than a filter without a charge.
