Nadair Washable Permanent Central Vacuum Filter (Models 70025, 75022)

This Nadair washable permanent filter (Part #37508) is the reusable motor-protection filter engineered for select Nadair central vacuum power units. Rather than buying disposable replacements, you clean and reinstall the same durable filter, keeping fine dust away from the motor and maintaining steady suction throughout the home.

• Type: Permanent, washable filter
• Reusable: Rinse, dry, and reinstall
• Fits: Nadair central vacuum models 70025 and 75022
• Function: Secondary motor-protection filtration

Maintenance is straightforward — remove the filter when you empty the canister, tap out loose debris, rinse under water if needed, and let it dry completely before returning it to your Nadair 70025 or 75022 unit. A clean permanent filter protects the motor fan from grit and prevents the airflow loss that comes with a clogged element. Inspect periodically for tears to ensure the filter continues sealing properly.
