Inova Air E20 Replacement Filters
Replacement filters designed for the Airclean E20.
Over time, different parts of the filter system may need replacing.
Some people choose to replace individual filters as needed, while others prefer to refresh the full set for balanced performance.
Supporting your air over time
If you’re here, you may be noticing that your purifier is not feeling quite the same…
perhaps the airflow has softened…
or the space no longer feels as fresh as before.
Over time, filters gradually fill with what they remove from the air.
Replacing them helps restore balance and supports your space once again.
Filter options for your E20
Over time, different parts of the filter system may need replacing.
Some people choose to replace individual filters as needed, while others prefer to refresh the full set for balanced performance.
The Inova Air E20 uses a layered filtration system, with each part working together as a complete set.

Most balanced option*
Filter Bundle Replacement
Together, these layers support ongoing air purification
within your space.
Choosing between individual or full replacement
If only one part of the filter system is showing signs of wear, replacing that individual filter may be enough.
If your unit has been in use for some time,
or the air no longer feels as fresh as before,
a full filter set can help restore more balanced performance.
When to replace
Replacement depends on use and environment, but you may begin to notice:
reduced airflow
lingering odours
visible dust build-up
the space not feeling as clear or settled
As a general guide:
pre-filters may need replacing more regularly
HEPA and carbon filters last longer over time
A simplestep to restore your space
Replacing filters is not about perfection —
just a simple step to help your purifier continue supporting your home.
A steady approach
The change is often gradual…
until the air begins to feel clearer, lighter, and easier to settle into again.
Looking beyond filters
If the air in your space still feels heavy or unsettled,
you may wish to explore broader support:
