Don't worry, they're accessible. There are typically two main filters: a pre-motor filter and a post-motor HEPA filter.
- Unplug the vacuum and empty the dust cup.
- Pre-motor filter: Look inside the empty dust cup compartment. There should be a foam or felt filter you can lift out. This one catches debris before it hits the motor.
- Post-motor HEPA filter: This is usually located on the back or side of the vacuum body, behind a removable cover. Look for a latch or screws. This filter ensures exhausted air is clean.
If that didn't work, and you can't locate them, your specific model might have a slightly different layout. Search online for "NV356E filter location" for a visual guide.
Heads up: Clean the pre-motor filter regularly with water. The HEPA filter is not washable and will need replacement when it appears heavily soiled.
