How do the replacement filter refills work?Updated 5 months ago

When you purchase an air purifier, you can choose to include automatic filter refills. There is 1 free 3-in-1 True HEPA Filter included in every Windmill Air Purifier. After 6 months, we'll send you another, so you can change it out right away and stay on track. When you have auto-refills enabled, it's only $60 per filter (vs. $80 for one-time purchases). So you save money and have better peace of mind!
