About the Shark IZ462H
The Shark Vertex IZ462H is a cordless DuoClean stick vacuum with a removable battery. It uses a post-motor HEPA filter in the main body plus foam/felt pre-filters; this page covers the HEPA filter, which seals fine dust in and needs occasional replacement rather than daily care.
The IZ462H HEPA filter is a pleated post-motor unit downstream of the cyclone. It's cleaned far less often than the foam/felt pre-filters and is where trapped allergens accumulate — replace it when it stays grey after a rinse or the pleats deform, as a tired HEPA both cuts suction and leaks dust.
✓ Buying Advice
Genuine Shark HEPA guarantees the pleat quality and seal; aftermarket HEPA filters for the Vertex line are cheaper — acceptable as long as the listing names IZ462H and states HEPA. Pair it with a fresh foam/felt set for a full filtration refresh.
⚠ Common Mistakes
The main IZ462H mistake is treating the HEPA like the washable foam and rinsing it constantly — over-washing collapses the pleats. The second is forgetting it exists entirely and only ever cleaning the front foam/felt. Also remove the battery before opening the body.
