What Is a HEPA Filter?
Because the fibers are densely packed, they create a very small pathway for air to travel through.
Washable HEPA filters can be cleaned, but only if explicitly listed in the manufacturer’s instructions.
This isnotthe actual HEPA filter, though.
For washable filters, your best bet is to follow the manufacturer’s instructions and timeline.
In short, replace a HEPA filter when the air no longer moves through it.
These particles can be generated indoors or outdoors and migrated through open windows, wall joints, or cracks.
you might usually find off-brand versions for less online.
Also, the added moisture can cause clogs and reduce airflow.
