Review on Fette Filter Compatible Navigator Lift Away by Christine Brown

Terrible. If you are allergic and have a shark to prevent it from picking up dust and allergens while vacuuming, AVOID THESE FILTERS. You can smell the dust being thrown up (just started with those filters, and yes, they're built in right) and it also makes me dust a lot more often. Since using these filters we have been overworked and have eye irritation that was particularly worse immediately after vacuuming. crap quality
