Frequently asked

What filter(s) fit a Shark AZ1800 vacuum?

The Shark AZ1800 uses the AMXFFKAZ2000 (foam+felt) filter.

Does the Shark AZ1800 use a HEPA filter?

Our data doesn't list a HEPA filter for the Shark AZ1800.

Should I buy the OEM filter or an aftermarket one?

The genuine filter is the safe, exact-fit choice. A cheaper aftermarket filter can fit the same slot too - check reviews for real-world fit and suction performance before buying, since vacuum filters generally aren't independently certified the way NSF-listed water filters are.

How often should I replace or wash my vacuum's filter?

Washable filters should be rinsed (water only, no detergent) every 1-3 months and fully air-dried for 24 hours before reinstalling. Non-washable filters are typically replaced every 6-12 months, or sooner if suction drops.
