Product & Filter Maintenance
Complete Product Maintenance
This page provides convenient reminders for important routine maintenance required for certain Therma-Stor products. For complete instructions regarding your Therma-Stor product, please refer to your product’s manual.
Standard Filters (MERV 13): These filters can be vacuumed cleaned on a regular basis. However, they should be replaced about every 6 months.
High Efficiency Filters (MERV 14): These filters can be vacuumed cleaned on a regular basis. Because it is a secondary filter to the standard filter, you should replace it every 2–3 years. How often you need to replace your filter(s) will vary by application.
