CleanLeaf 1100 Series Replacement Foam Pre‑Filter

What does the CleanLeaf foam pre-filter do?
It captures larger airborne particles such as dust and lint before air reaches the main filtration stages, helping protect internal filters and maintain airflow.

Which CleanLeaf systems is this foam pre-filter compatible with?
This foam pre-filter is designed for CleanLeaf air filtration systems that use a foam-style pre-filter. Models include: CleanLeaf 1100 Series (CL‑1100‑C7, C18, C21, H).

Can the foam pre-filter be cleaned and reused?
Yes. The foam pre-filter can be vacuumed or washed and reused. Make sure it is completely dry before reinstalling.

How often should the foam pre-filter be cleaned or replaced?
Cleaning frequency depends on the environment, but it should be inspected regularly and cleaned or replaced when visibly dirty or when airflow is reduced. Clean as needed based on dust load; replace when it shows wear or damage. Use an optional Magnehelic® gauge to track pressure rise and time changes

Does replacing or cleaning the pre-filter improve system performance?
Yes. Keeping the foam pre-filter clean helps maintain proper airflow and reduces strain on downstream filters, supporting overall system performance.

Does it capture smoke?
It captures larger particles and helps protect the downstream filtration stages that handle fine smoke and odors. For effective smoke control, ensure the bag filter and carbon or HEPA stages are clean and current.
